gm map with VPC

[WhiskyTalon]

i tryed shearching with no luck.

My map sensor for my vpc is out and you know how hard it is to get hks stuff anymore. I have heard of people using the gm maps for the vpc I was looking for some wiring directions if anyone had them....or knows. if this will even work that is.

another quick question... will a vpc with a 550 chip suport 780cc injectors.

thanks in advance

yes...it should work. You should only find ground/5v PWR/SIGNAL on the map sensor...it also should be a 3 bar one...the only "problem" you can have would be that the map from vpc is only 2.x bar...it reads util 24 psi, a 3 bar one is 28-29 psi, so you'll probably run a bit leaner, but the gain knob should take care of that....however, you can find the map at buschur for like $150 if I'm not mistaken. For the vpc 550 chip + 780 inyectors you'll need a keydiver eprom for your ecu...If you don't have an eprom ecu, a cheaper way would be runnng a 660 vpc chip, and lower you fuel pressure a couple of pounds.
