I decided to test the a/f via the VF signal today, maybe some of you techies could help me out with the results..
At idle, cruising, and light throttle im getting 5v - Maximum rich.. So the engine is running lean and the TCCS is dumping extra fuel in.. OK
Mid throttle, up to 2psi it reads 3.5V - Minimum rich, so its gettin better..
As soon as I hit ~60-70% throttle, or anything higher than 2psi it goes right to 0v, Maximum lean..
Running completly stock fuel system and stock AFM.. mods are 57trim ct-26, 3" BIC exhaust to stock muffler, and custom air intake with hardpipes..
is this normal? is there any way to straighten it out a little w/o risking engine damage? or w/o spending a pile of $$$ BTW, i do not have dyno access.. Since its already lean at idle, I didnt want to back the screw out of the AFM
