ECU question

Are the ECU units for '88 4Runner 22RE and 22R the same? I have a 22RE that I just swapped out for a newer one,and when I was checking something else, I noticed my ECU is labeled as a 22R. While the donor vehicle is still available,should I get the ECU that came with the motor I put in?

Yes, if you can obtain it, match the motor with the ECU.

Thanks for the reply,Brian,I'll do that.

The 22R only has an Emissions module. The 22RE has an EFI module and an Emissions module. Which one are you referring to?
