What chip do I need??

[PaulRV6]

I have a hot air engine 84/85 with the MAF from an 86 GN, coil pack is 86, cam sensor is 86, and injectors are 30lb/hr tomco, stock 84 turbo with 86 engine harness and Buick computer. First off I am missing the calpack chip and the engine control chip to try to make the engine run.
Not sure what chip I should be looking for for this and if I can just look for a stock 86 chip or a modified 84 chip?
I asked in the parts wanted forum but I thought I better check what type chip I need. Btw, this engine is on a stand and not in a car yet. Thanks

turbo tweak , go through the chip build form and just specify its for an 84/85 with 87 ecm , the chip will have less timing and lowered fuel at wot for a hotair lower boost as well as ignore the missing MAT sensor that the intercooled cars have

any stock 86-87 chip would allow it to start and drive but would turn check engine (SES) lamp on for the MAT (IAT ) sensor missing

if you wanted you could add an IAT sensor to the ecm but it wont matter it will just default to 71 degrees if its not there
besides the prom chip im pretty sure you need the small chip from a 7148ecm 3.8 (even from fwd fuel injected) to get it going

should run without calpak chip but will throw a code if missing (SES LAMP)
