I made an attempt to search for the answer as I am sure that this has been answered before but I came up empty handed.
I have owned my ae86 for 20 years and after 2 replacement 16v engines I am doing a 20V Black Top swap. I need an ECU but the only available factory computers that I can find are AT. Does anyone have experience running an Automatic transmission computer with a manual?
Are there significant performance issues? Are there any sensor problems to work around? Could someone point me in the direction of some good consolidated information resources for doing the swap?
THANK YOU!
- 20v noob.

its fine, no issues for 10+ years on an auto ecu. check in my sig for wiring DIY...

Thank you! Excellent writeup!
Do you happen to have the part numbers for the Black Top ECU? The computers floating around for sale seem to have differing part numbers and I want to make sure that I get the correct one.
Thank you!

any of these should be fine, its auto, 5 speed, & 6 speed throughout the years.
