turbo tune HELP!!! ok guys.... attached is my tune...
I have a 2 bar map sensor on a 1998 camaro z28, i hooked the map sensor up and at idle it is seeing maybe 50-60 kpa, with the engine off, 85-98 seems to be the norm... why would it fluxuate like this?? wtf? expesially the ambient pressure!
Ok so another issue, first time tuning with a wide band, but my car was very well tuned before and the highest number in the VE table was 130.... so i copied over that tune up until 105 kpa... now its having me put 144 at like 3200 rpms 78kpa or so, according to the wide band afr error... the wide band and hp tuners both read the same numbers within .1 so good job there guys!! im impressed.
It might just be in my head, but after i add an insane amount to the VE table i dont even see a difference...
I for sure have the 2 bar OS installed.. no doubts there, i dont have the secondary ve table anymore and it goes up to 210 kpa...
