Default Re: CEL at the track today...

When I got home and put the reader on it the DTC was P0108, MAP reading above limit. I looked at all the paramters it captured and here is what I can remember. (It dumped them before I could get them downloaded of course.)
MAP= 69.9in/Hg (about 20.3psi)
MAF= ~89 CFM? (this is the number I am unsure of)
ECT=213
IAT=192
Veh Speed=105
Load=99.8
TPS=99.6
RPM=5925
STFT=0
LTFT=0
Spart= -12(?)
It seems odd that it would through a CEL for a MAP reading of 20psi. To me anyway.
I didnt do to good at the track. The best run was 12.67@112.6mph, two 12.7's and a 12.8. I couldnt hook up good and spun a little on every launch. The track wasnt prepped at all. I beat up on a 07 Mustang GT 4.6L with a KB supercharger. He says he was getting sideways and got out of it. I think he did get out of it as he was Waaaayyyyy behind me. Dont know if he was getting sideways or not. I could see his grill in my mirror. I really need to get those new MT's I guess.

That is weird! I have never seen a 181 car hit max PSI.
