Standalone for AE86 4age to AE82 4age

[Chrisso]

You've got me a bit turned around here. So, you've got an AE86 wiring loom in there at the moment and you are a) changing engines, or b) changing computers?

It sounds like you're changing computers, as engine is just plug it up and go. So if you're looking for a standalone ECU then it doesn't matter. Just find one that you're comfortable with, considerations will be:

1)Price
2)Functions
3)Access to a tuner you trust

Just about all brands should be able to provide a linking cable to match your current loom to the computer. I would suggest a standalone over a piggyback.
