Default Re: Ls1 tuneup help

Sounds like the convertor is pretty close. It should definitely have a 2.75 first gear, and the final gear should be atleast 4.88. You need to look at the data log and check the Air to fuel ratio on the convertor flash and down track. The A/F ratio should be around 13.0 +/- .5 depending on what the car likes. If it is in the tune up, it would most likely be off on the hit of the throttle and into the flash of the convertor to have the 60ft that far off. You should be running atleast 10.40s with that mph. If possible, I would highly recommend changing to FAST Fuel injection in the future. Their software is much more user friendly, and their service at the track is unbeatable.
