If you have a kit harness or a ZX10, skip this box - If you are using a zx6r kit ecu with a stock wire harness and the Kawasaki kit harness adapter - LOOK!

This is the larger of the two stock wire harness connectors that plug into the ECU.

The 2 wires on the kit wire harness adapter (the $30 part you had to buy so you could use your stock wire harness), plug into locations 20 and 22.

The red wire to pin location 20
The white w/ green tracer to pin 22

#''s 20, 21, 22 and 23 are blanked with white pins in the stock harness from the factory. The wire location numbers are small and are 1 and 17 across the top and 34 and 18 across the bottom of the flat back connector plate in this picture.

Unclip the back flat connector housing, lift it up, remove #20 and #22 white plastic blanking pins.

Replace the flat back and insert the 2 adapter harness wire into their proper holes.

Look at the manual!
The small metal terminal must be oriented correctly, in reference to the  black plastic connector housing or it will not insert properly (fully).

With the connector oriented with the latch UP, the metal terminal must be oriented with the backbone of the terminal closest to the connector latch mechanism. I.E, the female pin receptacle "tube" of the terminal would be on the bottom of the terminal when oriented properly.

This picture shows the black plastic connector housing with the latch mechanism oriented UP.

1. You'll have to first "pick" your machine. That sets up the program with your bike's parameters and some other things.
   Main menu: click on Set, Machineselect.
   1. If all went well in the install, you'll see a list of bikes. The 05 zx6rr(ZX600N) is used for the 05-06 zx6rr's and the 05-06 zx6r 636.
      You have to pick the correct machine, and then close and restart the program. (that is a rather interesting procedure...)

1. Main menu: click on "File/Open"
   1. If all default paths were accepted during install, you be able to choose a map that is in the WORK subdirectory of the selected machine's subdirectory (machineselect).

1. This is the beginning table. It consists of a group of "zero" maps for the permanent ROM based ECU tables that Denso flashed into the ECU.
   1. You could download the "standard_data.est" into the ECU and the bike would run the same as before.
2. Choose the "standard_data.est" file.
   1. You will now be able to choose a single table in the next box. Pick any one of them for now or hit "cancel". Once you have gotten to this box, either way, you can check the PC to ECU communication.

1. Main menu: click on "Set/Monitor".  That's so you can see the throttle position and RPM, etc. while the engine is running. Turn on bike's ignition and kill switch to "Run" and "start" Monitor.
   1. If you get some numeric values of temperatures and pressures. Great. That means your com Port is set correctly.
   2. If "Failed open RS232C port", then close Monitor and go to Main menu: Set/RS232 and try another serial port that you actually have, till you've tried all 8.
   3. If you are using a real 9 pin serial port, they are usually 1 through 4.
   4. If you are attempting to use a USB to Serial converter, it's usually going to be ports 5 though 8.
   5. You could have cheated and looked a your computer hardware and seen what open com ports your computer has......
2. If you choose the right port, the cable is connected properly, the bike's power is on and the kill switch is in "Run" position, you should have the Monitor showing current data about the bike. You can start the bike and watch the values change.
   1. Monitor doesn't have the world's quickest refresh rate, but unlike some aftermarket tuning "schemes", it seems to be very solid.
   2. Remember - the ECU has to run the bike AND communicate to the outside world, reliably.
   3. Our Teka 4usb refresh rate, for instance, will visually trace on the table, you "blipping" the throttle in neutral and that's quicker than anything else I've seen - but Denso's Monitor is perfectly fine for steady state testing.
      
       
3. Bummer is if you are using the correct com port and you get a "Can't find ECU" error message.
   Then it's:
   Check bike's ignition switch = ON
   Kill switch = RUN
   Wire harness adapter's 2 wires are inserted in the large ECU connector and the connector is plugged into the ECU.
   Wire adapter is plugged into "ECU to PC/Laptop Interface Cord" AND the bike's stock wire harness.
   ECU to PC/Laptop Interface Cord is plugged into your serial port.

   That's all I can think of at the moment. Hopefully that's all you need.

   I happen to use a laptop to do KRT tuning. Older laptops tend to have a serial port and newer laptops tend to only have USB. I try to not use USB to Serial converters for the initial bike/computer setup as there are common special USB properties than can prevent communication - even though all seems ok.
    

1. Go up to main menu: Select File/Menu or hit the "F1" key.
2. Up pops a box named "Menu dialog".
3. On the right, select "Multi Map edit".
4. Up pops another box that is mostly grayed out, "Multi Edit Mode" is selected and (oddly) says "#1,#2,#3" and is (probably) supposed to say #4 if you have the right Windows font. (and none of my computers do). It only temporarily links the 2 fuel maps and nothing else.
    
5. You can't really select anything different here. 
   1. When you click "OK", you are temporarily locking "Compensation Map for Injection No.1" and  "Compensation Map for Injection No. 2" together.
      1. Compensation inj table 1 is the fuel rate for cylinders 1&4 and Compensation inj table 2 is cylinders 2&3.
   2. After you click OK, you'll see that your upper menu "Label" field will say "#1,#2". That means Compensation inj table 1 and Compensation  inj table 2 are locked together (and not just cylinders 1 and 2).
       
6. Magic! Something familiar is on the screen.
   1. On the top, the "Map" there's actually a bunch of overlaid lines at "0" (it looks like 1 line) and on the bottom, there's a familiar fuel injection "offset TABLE". Looks similar to a Teka 4usb or PC table.
      1. Technically, a graphic representation of a numeric "table" is a "MAP" and a spreadsheet-like looking grid of numbers is a "TABLE". Dynojet calls their Tables "maps", so, that might be confusing when you work with a larger manufacturer's products.

Pretty much ignore the graphic representation of the maps, it's pretty but not much useful......

Denso doesn't let you see the actual base fuel, ignition and other tables, they only let you modify offsets (to their predefined limits). It's the same in the Suzuki, Honda "kit" Denso ecu's.

Note!
The Denso software is set up to really NOT want you to accidentally leave the 2 Comp inj Maps linked. It will delink them whenever you change to another type of map (like the Ignition table) or when you exit the program. So - if you want them linked (and you usually do when doing initial tuning, check that "LABEL" displays "#1,#2" exclusively in the dropdown listbox.

 

Look at the fuel map:
Now is the time to make sure that the rpm increments and THrottle % position increments are what you want. If you don't do this now, you can't do it later without discarding all tuning work you've already done. (you only make that mistake once....)

Double click on the rpm increment you want to change, and change it.
The program will force you to do 14 increasing rpm value steps, from left to right. On the 600's, you probably would use 2000 to 14500, and I think that the supplied "standard_data.est" for the 05 600 was 2000 to 16000.(skipping 3000)  - but I'm pretty sure that they didn't give YOU the ability to program a 16,000 rpm redline!
On the 05 zx6rr, you can only add (from my memory) 300 rpm to the original rev limit, still less than 15,000 rpm.

With a stock rev limit, I'd use 2000 to 14,500 rpm
If you raise the rev limit, maybe you'll have to use 2000 to 15000 in 1000 rpm steps.
At any rate, 1000 rpm increments are alright for high rpm.

If the KRT software could do it, It would be possible to get very slightly better power results, using 500 rpm increments, but - that small potential improvement disappears if you are tuning "to an air fuel ratio", rather than loading the engine and measuring power (meaning that dynojet dynos and the rest of the "tune to an AFR clones can and usually throw away potential power)

Remember, these are the REAL rpms, not the bike's TACH rpm. The stock tach is ~10% optimistic (as common with stock tachs).

A relatively stock zx6r/rr doesn't make power at a real 16000 rpm or is mechanically, in the valve train area, strong enough, so it's not recommended to raise the rev limit to 16000. In fact, in a stock engine, DON'T DO IT and the KRT ECU that you buy won't let you do it, anyway

You cannot add, what is called "an extra rpm breakpoint" in FI tuning language, you can only change the value of an existing breakpoint. I think that there's 14 rpm breakpoints (from memory).
You can change the THrottle % breakpoints, too. I feel that 100, 80, 60, 50, 40, 30, 20, 15, 10, 7, 3, 0 are pretty comfortable and a little better than the "standard_data.est" values. I'm doing this from memory, so if you need another, I'd add 25% TH). Those are not quite as fine an increment as the THrottle % breakpoints that are used in our Teka 4usb module, but the 12 KRT THrottle breakpoints are better than a power commander's PC3 and PC5 coarse THrottle breakpoints.

You might notice that I capitalized "TH" in "THrottle". That's because eventually, I'll just type "TH" and you are supposed to know that means "THrottle".

After you make the breakpoint values, Save the map as "MySTD_data,2k16k,myTH.est" or something that makes sense to you. It will, by default, save it in your selected "machineSelect" bike's WORK folder.

Now -
BEFORE you merrily go on to your base test  with your "zero"  "standard_data.est" map,

Send your "Mystandard_data.est" file to the ECU with "Data Exchange"

1. This is a set of KRT tuning "constants" for the Denso KRT ECU.
   1. All Area Fuel Compensation Value
      1. This is the table that overall richens or leans out the fuel tables - as a foundation for the other fuel tables.
      2. This is the table that you find that you need when you have done about 75% of the mapping - Suggestion - do the main fuel mapping first - don't spend too much time doing part throttle at first.
   2. OverRev Shift Value
      1. On the 05 600 6rr, it's probably max value of 300 rpm - add more and a interesting box pops up and lowers whatever you typed in to something under the limit.
   3. Fuel Cut
      1. Use fuel Cut at closed throttle, Use: "0" - No fuel under shut throttle - Slightly better mileage, twitchier from closed throttle to slightly + throttle
      2. Not Use fuel cut, use: "1" - FI still delivers a bit of fuel at closed throttle, makes for smoother on/off/ throttle operation.
   4. Exhaust Valve
      1. Use: "0" - If you have some sort of variable Kawasaki "exhaust pipe valve" or (and I haven't tried this) only a slipon exhaust might still have one or some zooty "you probably don't have one" KRT exhaust.
         Remember, you'll have to map the Exhaust Valve opening across the rpm and throttle positions!
      2.  Not use: "1" - which is what 99.9% of us have......

1. Engine off, key on and Run switch on
    
2. Main Menu > SET
3. Select: Data Exchange
4. Select Read
   1. It will ask you to read from
      1. ECU data
         1. Read direct from ECU to probably see what's there and probably save it to a file on your computer.
      2. Edit Data
         1. What you've been adjusting (rpm and throttle breakpoints, fuel and ignition and whatever values on your computer
      3. File Data
         1. It will prompt you to find a file on your computer that you want to download to the ECU.
5. In this example, we want to send your set of modified tables to the bike's ECU - so, it's either Read the computer's saved "Mystandard_data.est" File Data and download it to the ECU or you could just send the current Edit Data that's on your computer screen (but make sure you save it!)
6. After you hit READ at the bottom left of the box, you'll get a confirmation, like "Read from edit data (or file or ECU data) ---> Complete"
7. To Write or send your data to the ECU, simply hit Write. (Engine off, key on and Run switch on)
   1. It will take about a minute to download.
   2. When 100% finished (it will say so),  turn the ignition off for 5-10 seconds, then turn it back on.
      1. I'm not absolutely sure that it's necessary to cycle the Denso ECU, but, whenever reflashing an ECU, it's wise to second guess the manual.
         
          
8. You've got 3 other choices across the Write box
   1. Verify (to cross check you data against the ECU data)
   2. Clear (to re-choose data to send)
   3. Close (to close this box and get on with tuning)
       
9. Now you can do your base dyno test with you new rpm and / or THrottle % steps

1. Main Menu > Monitor
2. Click Main Menu > Item Select
3. Clear all but Engine Speed and Throttle Position with the  <<(U)  dealio.
   1. each item displayed takes about 1/4 second to refresh and the more items selected, the slower the rpm and TH % reads out.
       
4. Main Menu > Monitor
   1. hint: shortcut from screen with cntl-M
5. On the Monitor window, click Start
6. Now you've got RPM and THrottle % readout on the same screen as whatever table you select to tune.

Set up the RPM and TH % breakpoints like we want them -

Sent our Constants List like we want them -

Set up the Monitor function so that we can read RPM and TH % -

Sent the complete set of tables to the ECU -

Ok - maybe it's time to actually tune.

The tuning will be focused on using an EC997 dyno, as it's extremely easy to tune to Best Power. Probably easier to learn to tune to Best Power than to learn to work the Kaw, HRC and Suzuki Denso kit box software.........

And now, how to win friends and influence people.....

It's almost impossible, in less than most of a day, to tune to Best Power on a dealership level dyno as many race teams have in the USA. That's why you see kit ecu's with power commanders piggy-backed and Ignition modules piggy-backed to the piggy-backed fuel modules with piggybacked quick shift modules piggybacked on the other 2 piggybacked modules for fuel and ignition changes. The only reason for that is that they don't have the dyno capability to tune to Best Power. (one race team member, when discussing their dynojet dyno's tuning capabilities....("We don't just have a regular dynojet dyno." "What do you mean?" "Ours is built into the floor......" "Oh...I see.....")

They religiously "tune to an af ratio" on a dynojet dyno at racetracks and think that's the best it can be. (I guess that's why they do it....). It takes 1 to 5 hours to tune the entire rpm / TH band, fuel and ignition to Best Power using an EC997 dyne system  to close to 100% potential  - Meaning it's tuned to Best Power AND well enough to be a streetbike, with smooth lowend cruise, etc... Takes about 1/2 hour - 45 minutes of running to start from scratch and do a "racetrack" quality job. A "Racetrack" job is making the bike idle and take throttle, then tuning any horrible spots, then tuning the all the throttle positions and rpms to Best Power that the rider will use on the track.
A "Street" job takes longer - as you have all the "cruise" throttle positions and rpms to do too.
It takes a dealership level dynojet dyno an hour or 2 to completely tune to "an af ratio" at all rpms to 90% potential. (and they are not even close on the ignition 90% of the time) and probably still not at a silky smooth streetbike cruise level.

There's 3 big (successful) teams that knows that "tuning to an af ratio" is not a goal.......

1. When making fuel, ignition or other table changes (I don't know if it works on the "Constants List")
    
2. You can make a value change in a cell - and while that cell is still highlighted,  hit "Shift + Enter". and that single cell's or selected range of cells value/values will be sent to RAM and the change is instantly testable. 
    
3. But REMEMBER! ALL table changes that are on your computer that you sent to "RAM" disappear if you turn off the bike - and to get them back in RAM, you'd have to go to every table, select every cell and re "Shift Enter" again (takes a long time and is potentially confusing.
   1. If you want to make those changes permanent (and you may as well), you have to use "Data Exchange" and "Write" edit or file data to the ECU.
   2. I usually do a bit of work, save the computer "Edit Data" to a unique filename and then "Data Exchange, Write, to ECU".
      1. Suggestion for saving - so you can keep track -
      2. Example:  Create a new subdirectory in the WORK directory, like "zx6rr,05,Akra_sys,FPstacks,BMCracefilter,Frech,Eric"
      3. Save working edit data with date, time and short note as "2009,03,18,0528pm,work_on_fuel_table.est"
      4. Then "Data Exchange" to the ECU - Then, the bike has all the edits permanently in the ECU and they will still be there when you turn the bike back on.
         1. Remember, if you are tuning and get totally confused and flustered, you can always "re-Data Exchange" the "all zero" "standard_data.est" to the ECU.
             
   3. Generally, if I'm tuning and accidentally turn off the bike, I'll just save the current file on my computer and "Data Exchange" the whole kit and caboodle to the ECU - easier and it will send all the tables in about a minute.
       

1. Accidentally forgetting to link the 2 fuel tables when tuning (and you spend hours tuning and wondering why the hp isn't changing very much when you are just changing 2 cylinders our of 4......)
2. Accidentally turning off the engine when you are tuning in "RAM mode" and forgetting that "RAM" changes disappear on engine restart / ECU reboot.
3. Using rpm breakpoints that aren't optimal and having to restart all your tuning all over after you fix them.
4. Finishing tuning to perfect, but forgetting to "reflash" the bike's ECU by performing a  "Data Exchange"  (file or edit data to ECU)

1. Link the fuel maps (Comp Map for Injection) 
   1. Select from Main Menu, "File", then "Menu", then "Multi Map Edit" (or hit "F1")
   2. Select "Multi Map Edit" (it will only link the 2 fuel maps)
   3. Adjust the fuel delivery to make best power at each rpm break point in Steady State (NOT in an inertia  Sweep Test)
2. Select Ignition Table from Main Menu
   1. You will have to delink the Fuel Tables (it's OK)
   2. Adjust ignition offsets for Best Power
      1. On the 03 to 06 zx6's, there's a lot of +4.92's  (+4.92 is the software limit) at part throttle.
   3. When you are done with both the fuel and ignition, it's probable that you'll have a transient "burble" when applying throttle from low rpm -
3. Select "Compensation for Acceleration"
   1.  "Compensation fro Acceleration" is the ECU's "accelerator pump" function.
      1. Decrease values at lower rpm, until the burble goes away when snapping the throttle on a fully warmed up engine.
         1. -10 to -20 is possible from 2000 to 5000 rpm.
      2. The only way to optimize "Acc Pump" values at higher rpms is to try it on the track and see what "feels better" to the rider. Some riders like more and some rider's styles like it less - and nobody likes a burble when applying the throttle while in a  2 wheel drift.
         1. When in doubt, leave the high rpm "Comp for Acc" values at "0". and maybe try adjusting for the rider in small "5" steps.
