Sti_Guy04, I highly suggest doing a lot more research and picking up this book
before you go any further or post any more threads about engine management.
no closed loop wideband feedback on the UTEC? really? couldve fooled me, because i have it on mine...and every other UTEC out there. yes, its still the stock ECU calculating it, but the injectors are still being driven by the UTEC.
i daily drive MY car and it works fine for me with a UTEC. sounds like the UTECs youve driven werent tuned very well...ive spent countless hours tuning and tweaking my maps, and they are very smooth.
