I have a Jeep that had the Ripp tune in it, but it would hit the rev limit before it would shift. I pulled the tune with HP Tuners and was able to read it. I made a few adjustments for the transmission and dialed in the tune better. Customer was very happy with the tune, but now he turns the A/C on and it feels like it really lacks power. I did a datalog on the Jeep and found the throttle to be closing when the compressor would turn on. It does this in a very cyclical fashion. Turn the A/C off and it's fine. Is there some A/C table that I have missing in the software? Is there some adder table that I'm overlooking. You can see in the datalog that the throttle and load change, but my APP is rock solid, only with the A/C on. Right around the 9 minute mark you can see it happening. 2012 jeep wrangler todd wiedmeyer ripp supercharger mod6.hpt
