Resurecting this thread in order to make a request. Does anyone have a custom TuneECU map for a 2012 ST3 with a similar setup as mine? I have a CRM low mount exhaust (cat gone) and stock headers, but I'm using the Arrow low mount map currently. A CW low exhaust would be comprable. I have the stock air filter in, SAI and O2 sensors disabled (SAI removed and blocked off, O2 sensor still in the bung), and the intake screen removed.
Using the Arrow map I'm getting a loud pop, almost a backfire, everytime I upshift from 1st to 2nd gear. I use the quickshifter for the other upshifts, so there's no pop. That's the main thing I'm looking to eliminate. Is there something I could do, other than a better tune, to eliminate that? Otherwise the bike seems to run fine. Haven't spent enough time with this map and exhaust setup to tell much else besides that it seems to pull harder, but I'm guessing from the popping that I'm running a bit rich. Is that a reasonable assumption?
Thanks for any pointers, or better yet a custom tune, ha ha.
