[AIROCOBRA]

Hi ,can any of the ecu experts tell me what the difference is with the two ECU I have.

1st ---- BLUE COLOR STICKER 89661-12080
ND 175700-0560 12V

2ND ---- ORANGE COLOR 89661-12051
ND 175700-0180 12V


Both units are same size and have same plug connections.

also to add to differences in ecus

wouldnt the jdm ecu not have a pin out for a thermo fan controller because rwd 4ages run a clutch fan ? as the ae82 twin cam ecu would

Thermo's in AE82's run completely independent of the ECU. So no, there isn't any pinout difference in relation to thermo's.
