03-05 J-Body ECO Tuning
Tuesday, October 02, 2007 11:38 AM
Does anybody have an 03-05 Cavi/Fire with the 2.2 ECO that has used HPTuners? I have an automatic and I am trying so hard to find a good tune. I have been messing with shift points but i cant get them down. Im making 136whp and 138wtq and still only hit a 16.00s at 86mph. How much timing can this motor handle running on premium gas? Any help with this car would greatly appreciated since I have gottan little to no assistance on the HPTuners forum.

Have you looked on HPTuners file depository....on their website?
Timing really depends on the motor. How much Knock are you getting?

Have you read any of Shifted's sticky's on J-body?
