I haven't had my car run correctly since I put it together, and from what I've learned talking to a few non-hellcat tuners, they believe my tune is to blame.
A local, well respected shop did it, but again, My car is an odd duck; I road race/time attack it, and his customers are drag racers. With his tune the car runs fine on the dyno or street, barely runs on the racetrack with dead pedal issues and the car sounding "off" and not pulling like it should.
I've used this forum to help me tweak the tune trackside, with some success, car seems to run better.
Would anyone be willing to peak at my log file and my tune and give pointers?? Sitting 4th in class, I know I could still get on the podium if the car runs properly for a whole lap!
Setup is:
1970 Dodge Challenger
Tranzilla Tremec T56, Mantic Triple Disc Clutch
Mopar Hellcrate ECU/Harness
Junkyard Hellcat 6.2 and 2.4 IHI
SDG Motorsports Supercharger W/ported snout
2.85 Upper, ATI 10% lower
1300 Injectors
Dual 525 hellcat pumps, PWM Via Tapped harness
Large LTR
Peterson Dry Sump Oil pump and system
Headers
Thanks in advance anyone willing to HELP MEEEEEE!
I am NOT a tuner so I'm way over my head here.
EDIT: Worth Noting this log file is after I made more tune changes, AND is a street log, not an on-track log as I'm trying to get the car to run better before my next session. I will log and post my next on track laps. I did not experience any dead pedal/weird running issues on this log, fingers crossed maybe the tune is better, or if history repeats itself the car will run poorly on the track again.
