northstar v8

using a PCM from a 94-95 TBI truck(the 7427) looks to work with any of the -e trans with a PCS, and for MUCH cheaper than a TCI unit and with more customization as well.

IIRC the northstar monte required quite a bit of modification to the cooling system, ALOT of wiring and circuit board construction (last i knew the trunk floor had pretty much covered with wiring and boards) and about $20k+ in work, it also has never run correctly

it's running, just rich as hell since the guy decided to piggyback the 93-95 N* PCM instead of going to a different, tuneable PCM. and last i knew, it was around 20K, with a shop doing all of the work, but he also put quite a bit into the motor and it's up to an estimated 450 crank HP.

chrfab has a setup using Holley commander 950 with their own base program already installed. I ran into the same problem with trying to use a stock aurora pcm, screw that! go MSII, FAST, or holley. I'm personally waiting on finances for the ecu system, then i'll continue her.

much cheaper, at least as versatile and hella easier to find replacement parts for tuneable OBD1 PCMs.

i had/have plans for a 16196401 and 16197427 paired together...

SPILL! I've had the 4.0 sitting in my olds 88 for the last 2 years with no comp, I can't justify the 2k+ in ecu's to make it work, I'd rather drop the dough in my drag car.

to ratrod it, you could use a PCM/MEMCAL from a 95 aurora with the same FDR to control the trans and another ECM/PCM to control the motor. not sure how well the N* PCM would like that though, since it likes to chat with other modules on the dataline, especially the instrument panel and traction control module... i've been working on hacking through it, but damn... dual 64KB BINs take a lot of effort and time.

i actually made my nAst1 patch for the $A1 mask specifically with the northstar motors in mind(VE and spark tables that run up to 8400 RPM).

however, maximum cheap, yet still very reliable/tuneable: use a 1227727/1227730 to control the motor on the A1 mask, and whatever the hot PCM is from the 94-95 4L60E and 4L80E trucks(ask around on thirdgen.org, they love that thing). you would need to work out the base trans control maps(you may be able to find the info, if you look in the right places), but it would give more control than anyone would need.
