For '90 up there should be no ECU differences. Manual and autos should use the same ECUs, since there is no transaxle electronic controls.
If anyone knows differently, post it up! However, I believe all Festiva ECUs from '90 to '93 should be the same. '88 and '89 ECUs will be different, and are probably different between the carbed and FI/ATX cars. I have no idea if the FI/ATX ECUs from those early years will be the same as the later FI ECUs. Anyone know for sure?
For example, I'm using a 5 speed ECU from a 323 on my B6/ATX swap car. It's a two plugger, just like '90 to '93 Festiva ECUs. The ATX 323 ECUs are three pluggers and won't work, probably because they control the electronics for the 323 ATX, which was a 4 speed automatic.
