I installed the FuelPack, based on the instructions, pulled the latest settings off your internet site, entered the numbers, shut everything off, re-checked the numbers, everything seemed normal, the bike fired right up, I went for a 15 miles test ride, no problems. The bike accelerated normally, I hit the free way, and I rolled through the gears, up to maybe 70 MPH, all seemed normal. The bike accelerated, and decelerated as expected, it sounded good, no deceleration poping, I let it cool off for maybe 30 minutes then went for a second ride.

I rode maybe 2 miles on side streets, topping out at 40 MPH, all seemed normal. I started to pull out onto the Freeway, since the first ride went well, I wanted to test hitting the gas much harder on the Freeway on ramp. I nailed the throttle hard, and it felt like the throttle cable broke, (I have a throttle by wire bike, details below, that best describes what happened and how the bike felt) I twisted the throttle a little acceleration, maybe 500 RFM, and then nothing, I could not rev the engine. I tried again to accelerate, and the engine would not pick up speed. The check engine light came on. I more or less coasted to a stop. The engine never died, just acted like an engine with a broken throttle cable. I pulled to the side of the road, turned the bike off, then started it back up, still the same thing, I could not rev engine. I shut it off again, thinking I’d need to pull the main fuse, and reset everything, so I may have waited 15 seconds, but thought I’d try re-start the bike. It started, and the throttle worked like normal. I rode back home at a pace much like my first test ride and the bike ran fine. I assume nailing hard would make the same think occur again.

I sent an email to V&H, anyone else had a similar problem? If yes how did you fix it.

 

I've got a FP on my bike, and not experienced what you have reported. I can nail mine and it responds immediately and with force. Almost sounds like something is loose in your TBW...did you take a look at your connection there?

If it happens again, disconnect the FP from the ECM and try your series of tests again. That should give you a clear indication whether the FP may be the cause of your problems.

 

Number 17 mode always set at zero with plus will raise the afr and go neg lower
it it, go one point at a time and you may find wht your looking for.

 

Well after a couple calls to Fuelpack tech support, I think I have by bike running the way it should. No long rides yet, but I am 99% sure I found the problem. The Fuelpack tech support, help me find the problem.
