    Opposite trims with throttle input

    2001vetteFFP.hpt tpstrimidle.hpl

    Thanks for the help. I got a stock 01 vet with a 102mm TB, dynatech long tube headers and exhaust. Just got the hp in and I cant trim what so ever and with any throttle input the trims go negative on one bank and positive in the other. This is my second attempt with HP tuners. My CTSV was my first with no issues. Thanks in advance

    actually with out throttle input, if I give her any fuel in the tune it will do the same.

    Your O2 sensors are crossed.

    Why a 102 TB on a stock setup? Is it the stock manifold? Stock Intake setup? Sounds like idle troubles are on the way.........

    is a FAST intake mani with 102mm TB. It was installed when we got it. Im already looking for a 90mm TB cause im sure is going to be a headache.

    BTW, the guys at the shop did find the sensors crossed. Tomorrow ill get her on the dyno and find out what else is wrong with this thing....

    THANKS MUCH!!!!
