Can a GM ecu be set up to run a TII
 

So I'm in the middle of my project here and I've hit a snag. I have a S5 TII motor and trans that I'm putting in my FB I have all the parts to bolt it in except a -SE oilpan, but the big problem is I've almost hit my budget for the next few months and I kind of want to get it going before the snow melts up here.

So I dont know what to do about the fuel system microtech or haltech seem pretty good but out of my price range till my job picks back up this summer.

But I tune alot of gm cars and trucks with HPTuners, and I can get a GM ecu and harness for next to nothing, I can change any setting the ecu controls so maybe I can get a 13b to run with it.

I just don't know how I could set it up right, I could make it batch fire that could make things simpler, but the ignition is what gets me, would I set it up as a 4cyl or a 6? I mean it does fire 6 times per rev right well 12 with the trailing? I don't know. Thats another thing I don't know how I would set it up to fire the trailing plugs a few degree's after. Or I could have the ecu fire the leading and have the trailing fired by a dizzy, but that just sounds like a bad idea that might end with pre-ignition and a dead motor. or I could toss in a 12a dizzy and use the ecu just for fuel, but the I lose detailed spark control and the ability for the ecu to pull timing with boost or high iat's. But at least I could drive it in and out of my shop.

What do you guys think.

Oh yeah a 12a front cover fits on the tII right?

thats kinda like asking a Boat captain to fly you an AIRPLANE.. although similar they're completely diffrent, people have put stock n333 turboII ecu's in to FBs.

Well with a few simple directions a plane isn't that difficult to fly. Well I have the stock ecu for the TII but I have no coils, plugs for the ecu, or maf. I only have the half cut wiring thats still on the motor

DIY Autotune makes a megasquirt based DIYPNP which will fit the stock harness for the 86-88 RX-7 - $425 with a little bit of soldering, but less than a full MS kit.

There was someone selling GM ECU's claiming they'd run anything, but I can't seem to find their website anymore.
I'm actually pretty sure you could get it to run fuel only if you played with it enough, but it sounds like it could turn into an exercise in frustration. If you can program any parameter and know what you're doing, maybe though. Do some reading in the Megasquirt, as that's a universal system adapted to a rotary.
