I'm curious to know the ECU's that were used in S4 and S5 T2's-I have a 10ae w/a S5 JDM engine and ecu-but today I looked at a wiring diagram for my afc and my ecu matches the S4 diagram-my ECU is a N333. A pic of a S5 ECU on 1300cc.com said N370-can anyone help here?

 

you know for sure it's an S5 engine? I was under the impression the only way to tell the engine year asides from dismantling was from the ecu?

Sintri - assuming the engine is stock there's a few meathods. TPS, Alternator, intercooler, waterpump etc..
