Thanks, but that is not the issue...after I ride the bike a few minutes its fine, and the idle is properly set. I am kinda looking for a non-obvious fix....I am very mechanical. Thanks though.
Had that exact same issue with a PC3 usb.. I RMAed it through DynoJet and the next one didn't do that. I say next one because I had to RMA my PC3 three times.
Let's see if I can remember the right order and symptoms....
1st PC3) wouldn't start without throttle and immediately died after starting unless you held throttle open until warmed up (same as you) This behavior started after it was about 3 months old or so.
2nd PC3) Started and idled fine but within the first week it started causing the bike to die as I was under throttle and the FI light would come and fuel pump was off. Had to reset the engine kill switch to restart. When bike ran it ran like crap.. back fired.. etc. This was the worst PC3 I had of the 4 I have had.
3rd PC3) Worked fine for a few months.. Then, out of the blue bike would crank but not start. By-pass the PC3.. yeah.. take off the tail section and completely remove it, putting back to stock ECU.. bike fired right up.
4th PC3) This one has been perfect for about a year now. I noticed that on this one DynoJet had lengthened the cable harness making it easier to locate in different places under the seat. Since '04 the PC3 instructions would not work for the suggested mounting point as the seat would sit right on it. See below for seat comparison. '04 and later seat is on left.
Where to install instead:
I should also note that I am very technically competent. Do I know everything about everything?.. no! But I assure you I installed the PC3 correctly all 4 times. (Actually more since I did plenty of testing before calling DynoJet each time.) I know enough about everything to know when I don't know enough about that thing! PC3 installs are not that thing!
My advice, don't wait, call DynoJet and report your issue. Talk to Phil Dupree, 800-992-4993 ext. 1127. If it helps, PM me and I will give you my personal info so you can mention my name if you like. Probably won't need it. They were very cooperative. Make sure you have covered all your bases.. I'm sure you understand what I mean if you have ever done RMA or been on the other end of technical support. Smart folks go up the tiers much faster.
