Help My camaro wont run right bad ecu tune? ok so iv been messing with my 67 camaro with the lm7 has ls1 hot cam and ford 30# injectors (36#) headers. it runs like crap stumbles but idles ok also very lean (spray carb spray in the intake revs up) but as soon as u hit the throttle trys to die wont rev up the scanner shows the st/lt fuel trims always at o and the o2s never close even when hot and there always at .445. i put the ecu in my 99 truck has the same lm7 motor but stock runs like crap wont rev up either shows the same thing o2s are closed when the motor is hot the stock truck ecu shows them close and the st/lt trims around -12 to 11. Now with the camaro ecu in the truck the o2s are still open when hot and the st/lt trim will run up to 56 and stay there. I think my tuner screwed someting up but wont say and not sure what to do and sugestions??? Oh yeah i posted data log about 3 days ago in this same forum just look for my post.
