Evo 8 ECU w/ an auto 2g

[PFC_CiarlilloM]

So, I've been looking into doing the Evo 8 ECU swap in my '96 GSX, but can't seem to find any information regarding if it works on auto's. All the write up's I've seen seem to be for various 2G manuals. I was wondering if it was possible to swap in an auto, and if anyone has a pin diagram for the swap.

i would look at the 2G auto pin out and the 2G manual pin out and compare them.

It'll work fine as long as it's wired right

@HighPSI TSI Guy, would you know the correct pin out swap I'd have to follow?

Bringing up a very old thread here. Has anybody tried this?? I was looking into this, but am not certain how this would be wired up so that it would communicate with the TCM to not only to let the TCM do its job automatically, but also to take advantage of features like boost by gear. Anybody?

Also make sure you scale the MAF and change the knock Multipliers (low/mid/high) 20/16/18

You can also go speed density using the Evo 8 ECU without much problem. There's a patch download for that:

Swap out the MDP sensor with a MAP sensor, and remove the MAF from the CAI.

Maybe this should go into the automatic transmission category of this forum. When you do the Evo ECU swap, you have to remove and swap certain pins. With a manual transmission, you swap and remove the proper pins and you're done. If you have an automatic transmission, you will remove pin 43, 48, and 91. I don't know what those pins communicate to the TCM. Pin 48 on an Evo ECU is fuel level, but I don't know what pin 43 or 91 do. If these 3 pins communicate with the TCM (RPM, Throttle Position), how does the TCM know when to change gears?
