Don Guhl is looking for someone to bring him a bike that he can put on a dyno and do some ECM testing on. If anyone is interested, please contact him. He is in Ephrata Pennsylvania. His phone and contact info is here: http://www.guhlmotors.com/contactus.html

Looking forward to seeing the results of the ECM reflash.

Same here, would really like to get rid of ridiculous speed limiter. Don Guhl is the man for this job. Had experience with his re-flash work on two bikes and the results were top drawer.:smile2:

Hey Fred,

Will this allow people to flash new fueling maps? I've found that on my yamaha the low rpm range was really jerky due to Euro emission requirements. Flashing a new fueling map really helped smooth power delivery and make the bike much more manageable. I know that the GW is pretty smooth to begin with, but I also know that having to engineer around Euro emissions comes with compromise.

Yes, what about fuel mapping?
While removing the speed limiter may be helpful in limited circumstances, better fueling and more power will be helpful all of the time.:grin2:

Best thing about this? Check that torque curve - completely flat, any speed/RPM. That is FREAKY...

I assume that messing with the Engine Control Module will leave a trace in the software that will void any engine and drive train warranty.

I would be curious to know what sort of power that engine can put out with a small amount of tweaking. I'm not talking different hardware, simply a remap. I bet it is pretty "healthy."
I'm very suspicious that this ECU knows it's on a dyno and holds back. The HP and torque curves are suspiciously identical to the previous engine and this engine is completely different. (Same basic boxer six, but that's where it ends.) Theoretically, this engine should have "gobs" more power than the previous engine.

this opinion has been covered exhaustively...it even shut down a similar thread so lets agree that were all aware of this and this thread is not meant for those that worry about the warranty. personally, id like for the information to flow and not get shut down again.

If you do volunteer your bike, best to do it with a rear tire that is closer to worn out than new. Dyno testing puts a lot of stress and heat on the middle of the tire due to the repeated full throttle runs with the bike strapped down into a straight up and down position. You don't want to do that to a new tire.

I took that to mean that the operator shut it down, not the ECU.

Yes, this is the next step in the process. Stay tuned, more to come...
