Phase 1 4EAT with 02 ECU?
Hello, I'm thinking about swapping an engine from an 02 WRX into my 97 OBS with the phase 1 4EAT. Will the new ECU work with the older TCU and trans, or will I get error codes etc. It looks like the 02 ECU has an additional input (AT load signal) for the A/T that the 97 doesn't. Can the new ECU do without this input? What has to be done to make the two work together? Thanks for any help.

possibly if you can get the signal wires setup properly....but it most definitely is not a plug and play deal
I think your best bet would be a full conversion, not just the motor |

I played with this idea for a while. It seems like the "best" way to do it was to make the car think it's using a manual transmission and then take whatever signals are needed for the TCU Effectively splitting the two to work separately (other than the VSS signal).
