like the title says about halfway through third my CEL comes on and the car goes into limp mode. any ideas i belive the CEL is for map sensor but i havent checked it in a while. any help is appreciated

 

well first off you need to check what the code is, and then we can go from there.

 

code 1 and 3 and im betting its not code 1 putting it into limp mode

 

bump

 

code 1 is the oxygen sensor... time to get a new one

and the code 3 is the MAP sensor and thats the one that trows u on limp mode

u either have to low of settings on the VAFC.. like -29% or so or u are boosting 10+psi

 

im at like -19 at full boost and its at 7 psi

Anything below -35 at 10-12 psi and up will put the car in limp mode....You should be no where near -19 under boost with 440s...

 

Change your in and out settings to -6 and -6. That should do it.

 

just tuned a 8 psi t3 b16 a on the dyno with a vafc last week... set the base timing to 18 degree. pull the vafc down to -45ish from 4500 to redline.. below 4500 set it to 35-8...

turn the fuel presure up to like 55 with vacuum off... see what that will do for you ..

 

put the settings at around -30 on full boost, run it on 3rd and tell me if still there

 

it idles with the afc set at -32 anyhting below and it idles like expletive

 

-19 is too rich. The richer you go on the set-point, the more you become prone to CEL due to the map curve.
