Fmu

convert it to ebl maybe

convert to 91-92 speed density and run boosted $8D code

go aftermarket ecm

 

Save yourself some hassle and go with an aftermarket ECU

 

I put a microsquirt in a '165 ECM case so I could use the factory harness on my '88 back in 2012 or so. Ran it for a good while.

I'm actually taking it out because I'm putting an LS in the car and going to run Terminator X.

I do like the system, but it doesn't have enough I/O for what I want to do with the LS (sequential, boost control, etc). I may cut up the harness and re-use it for ignition / fuel pump / cooling fan / etc control on my '79 Z28.
