Only true fix is Flashpro. In my opinion the Si isn't really worth having without Flashpro.I have a 2011 SI the rev hang is only apparent from 1st to 2nd for me. Rest of the gears are fine for me but when 1 go from 1st and 2nd sometimes i literally need to wait over 2 seconds for the RPM to drop
So I have an '08 FA5 would this still fall in this vin category?? I don't have the rev/lag/ hanging issue just a bit of hesitation And throttle surge in first gear on cold starts... I just thought it was a cold clutch or trans... But this is making me think further!The VIN range is 2HGFG2...6H700001 - 2HGFG2...6H707606..
What I sincerely recommend is that you buy FlashPro and at least run one of the beginning tunes that some of the folks here have built. From there I'd decide if you plan on any modifications and go visit the guys at e-tunez and have them dial in your tune.My 06 Si I bought used has bad rev hang. Called the dealer about the Re-flash bulletin. They want 96 dollars for it. What are my options here. Rev Hang problem sucks real bad.
