Evening all! I recently installed the PRL Flex Fuel Kit (amazing hardware btw!), flashed the TSP Stage 2 Tune, and was doing some shakedown pulls. Prior to this, I noticed ethanol percentage would go from 9/10% on 93, which is normal and expected. Occasionally, I would notice it reporting 15+20% intermittently, and couldn't find any info, so assumed it was normal.
Spoiler alert, it definitely is not normal for it to jump a lot on the same fuel.
Everything looking "Okay", I slowly increased pedal and boost and went to Map 2, and then Map 3. Fuel trims looked amazing, car felt okay despite what I assumed were normal ethanol readings.
Everything was fine until it wasn't. KCtrl shot up, fuel trims looked fucky, and my coolant temp gauge (ECT1 and gauge cluster) went to zero and then back up. Ethanol reported anywhere from 0 to 98%. No codes occurred, probably because this was a shakedown test and I didn't let it ride that way long.
Me and my backup driver parked it, and thought it was a bad install by us. It absolutely was, the ground for the kit was loose. After tightening, everything was fine, KCtrl started dropping, ethanol readings were solid 9/10%. Reflashed, KCtrl dropped from .59 default to "best" learned .49. Posting this so if anyone else has a similar issue, hopefully they find this thread, and pinging @PRL Motorsports , @KTuner , and @Two Step Performance so they can best help through customer support if they haven't seen these symptoms/fix before. Stay safe all!
