I have been watching my 05 GTO while driving, the dashhawk shows fuel mode, and lately i have been looking up to see it in open loop.. then it switches back to closed loop...
I thought it was perhaps a dashhawk firmware error, so i finally logged it with HPTuners tonight, and it is indeed showing OL during some of my logs...
I will post the HPL and HPT in a few minutes...
I have Longtube Headers, Catless Mid's, H Pipe, Spintech Mufflers, Ported Throttle Body.
