ECU from AT donor - OK for MT build?
Hi all,
I've read lots of posts about mechanical conversions from AT to MT and the necessary modifications, but have not seen discussion about whether the ECU (or TCU) will work. I would like to keep the stock ECU from my AT donor. Will there be a huge number of fault codes to deal with?
Anyone with experience on this?
Thanks in advance for any info.

I've used my AT donor ECU in my 5mt 818. I wired the car per the MT schematic. It ran and drove with AT flash with a few codes. I reflashed the ECU with a 5mt file. Everything works as expected.

Yes you can use it, but you'll need to make a couple wiring changes and then reflash the ECU to a map from a manual car using Opensource software and a Tactrix cable.
Edit: What Bob said.

Thanks both for the feedback. I'm hoping to have my donor stripped down over the winter/spring so I can buy the kit in the summer. Good to know I can use most of what I have.
