To avoid starting a thread, I'm offering my slightly used and working Booster Plug free to anyone who wants it. Just need to pay the postage. Like most people, I found it worked well for a bit then seemed to be tuned out by the ECU. But who know, it may work a charm for others. Just PM if interested.
I'll send the accelerator module free of charge to anyone in the EU, just PM me. I believe it works on the 650GS as well. Anything DeLewis said about the ECU applies here as well.
Thanks for the info Roger. What I need to do is contact DynoJet to see exactly when the PC5 kicks in during the start up routine. I already know the AutoTune doesn't even come into play until the bike is running. The PC5 does offer a cold start map option if you connect the engine temp sender to it, which it's currently not. That is probably worth the effort, but I need to see if the OEM temp sender works on a 0-5v range, most likely it does. I have subtracted a lot (-25, whatever that value truly is) of fuel from the lowest rpm ranges (500, 750, 1000). It's basically much too rich during the first 2-3 seconds as you pointed out.
