I have a BIN, but almost all the changes are on the HPT file. I have GTP injectors with a L67 throttle body and MAF. The good spark has been copied over the bad spark. The reason the O2 wasn't cycling was because it's in open loop. I'm replacing my O2 sensor anyway because the car runs lean in closed loop, and I have a feeling it's gone bad. Tiny Tuner will only open BIN files.
