Scarborough,
Hey guys how are you? I posted a few weeks ago that when my car would hit boost it would just fall on its face and wont go anywhere. Anyway after diagnosing the problem for a while, I found out it was a MAF. So I had a spare 2g MAF laying around and that fixed it.
Anyway now I have a new boost problem its inbetween shifts. Lets say I am in 2nd gear WOT and shift to 3rd and go WOT the boost takes long to build around. However lets say I am rolling in 3rd around 3000 RPM and I punched it, it kicks in right away.
The turbo is only a 14B. Anyway I tried hooking up the MBC the other way (backwards) and I found out that the boost kicks in right away no matter what I am doing. However, the car builds unlimited boost so its very dangerious. So could this be a MBC problem?
I noticed in the log I am running pretty rich Air to Fuel ratio wise. But my duty cycle is around 89%. Another messed up thing is that my BOOST gauge reads 14-15 psi and the BOOSTES only reads around 10-12 psi. Whats up with that? He is my log, and suggustions in tuning? Thanks a lot guys
Can't upload the log because its an invalid file. If you guys want the log I can e-mail it to you or something.
