DHP PCM tuned for exhaust and CAI ?

Frostbite545 · 05-09-2007, 05:00 PM

I bought my PCM when all i had was a Doctor Speed Intake, now that I have the Pacesetter exhaust, my cars O2 sensor is apparently really pissed off (from lack of backpressure maybe?)...and gives me a SES light. Does DHP tune the PCM specifically for what mods you have ? If so, how the heck am I supposed to get the computer to be as happy with my mod as I am?

go to autozone and get your computer codes read, it might not be the O2 sensor, find out what codes come back with the results and we can help ya from there

I have the stock cat, no resonator jsut a straight pipe from the cat, and it is the O2 sensor though im not sure of the exact codes now, my friend with a scanner looked at it. Apparently the oil pressure was low too... forgot to change the oil lol.

unless you requested something special from dhp you have their generic 1.0 pcm. i never had any issues with mine and im fairly certain they havent changed anything over the years.
