Harley Davidson Twin Cam Engine tuning

Factory Pro's EC997 Dyne Systems were specifically designed to have the ability to effectively tune fuel injection systems. Other common  "dealership level" dynamometers are descended from heavy, slow reacting inertia dynos that have inflated, untrue HP numbers.
They only "tune to an af ratio" and  not to where the engine runs the smoothest or has the best power or mileage or cleanest exhaust.

Locally,  we enjoy specialization in dealer referred tuning on Harleys.
Listed are recent projects that we've tuned for local HD dealers.

We don't sell or install HD engine parts or do retail HD tuning - we just do the tuning.

We can tune with:

ECU Programmers

HD Race tuner

This is the preferred method is to reprogram the stock ECU. It takes more time, but the improved long tern reliability and enhanced tuning flexibility is the gain.

From a tuner's point of view, the HD Race Tuner takes the longest, but is less troublesome than other ecu flashing software offerings.

After completing the tuning session, both the Directlink and HD Race Tuner provide equally reliable and long lasting service for the rider.  We have no problem using either of the products.

There is an initial cost to each. The Directlink requires a fixed cost key that would retail for about $250 to $300. The HD Race Tuner costs $400 to $500.  A good tuner may spend 3 to 5 hours to tune to Best Power and will probably charge up to $500 additional tuning time for the highly skilled custom tuning work performed on $50,000 to $100,00 worth of equipment. 

We don't do it, but some people still push a button on their common "dealership level" dyno and automatically "tune to an a/f ratio" with a power commander and call it done. That takes a lot less time, and doesn't result in optimum tuning or best mileage.

Add-on boxes

Teka 4 usb and Power Commanders

We do both (section under construction)

Other FI systems

Factory Pro has been tuning fuel injection for many years. We even design, build write software for the EC997 dyne system. The EC997 is probably the most purpose built tuning dyno in the world - with many features exclusive to our dyne systems, all provided to make tuning to Best Power settings (rather than common, low tech dealership level "tuning to an a/f ratio" dynos.)
We've used complicated systems, such as Magnetti Marelli, Delphi, Motec, EFI Technologies (the California one), factory Kawasaki, Yamaha, Suzuki and Honda - so, I believe that we can figure out most any FI system.

Outside services

Factory Pro's Marc Salvisberg is available to consult on software interface development. The secret to making desirable software is indeed the interface.
Factory Pro's EC997 dyne system software is a prime example of design. It requires very little book study to accomplish the tasks that a tuner would need to do. All with a progressions of simple screens and simple, on screen instructions. A new user can accomplish, with little training, do what would take a college educated engineer to do on some other, otherwise capable, dyne systems.  Email comtact

	The extension of the laboratory for engines of the Swiss Federal Institute of Technology was completed in about 1935. Its architect was Rudolf Otto Salvisberg (1882-1940). He had a successful career in Berlin but returned to Switzerland after the advent of the Nazis. His architectural style was somewhat similar to that of Erich Mendelsohn. The staircase of the laboratory is in normal use but well preserved. Edited to the tunes of Chemical Residue by Herbie Hancock.
