Top Swap Won't Run Right



Have you tried installing the GT PCM and see if the same thing happens. Do you still have the L36 MAP sensor?
 
If it starts with the old PCM without uplugging the MAP then I would guess that your PCM is jacked up. You need a PCM from a reputable supplier.
 


Are you sure you have the MAP wired correctly? Sounds like a bad MAP to me not a bad PCM

Do you have access to the file that is on the PCM or better yet...Who did you get the PCM from?
 
I'm pretty sure I did, i just matched wire colors up.

I'm tring to find the post of the guy I bought the pcm from, but they all seemed to disappered. I know he lives up here by me in Sioux Falls, South Dakota. He drives a 99 ( i think) black 2 door gtp
 


still haven't figured it out, it won't start with the map plugged in. I've tried different maps, no luck. I can start it then plug in the map and runs fine

Also did u do anything for a fuel pump
 
map is a 2 bar and pcm is 98... info on page 1

my guess is the tune is not correct. you say the pcm is a 98 but you have a 99 tb/maf. the base files are diff there. who knows what else is incorrect in the file. if you have access to a DHP i can give you a hand setting up the file. my money is on the maf not set up correctly and the improper matching of maf tables...

have you tried to wire back in a l36 map?
what all have you tried in the past 2 years?
 
The tune is from zzp so that's good but I am also using a fuel rail from zzp come to find out that the fuel rail they gave me was using a gen 1 fuel regulator that wasn't keeping pressure and letting fuel in the vac line so they are making me a new fuel rail with the gen 2 regulator so we shall see how it goes
