Hey guys, So here in the US we are trying to experiment with the S15 ECU running a KA24DE turbo in a S13 chassis. The wiring for the ECU pin out for the Dual cam KA24DE harness is the same. We ended up swaping over the Coil and Igniter from the Dual cam. But the Internal disc is different. After connecting the ECU we were getting everything to work well and calibrate all the sensors except for the trigger 1. This picture shows that the Disc inside the CAS is different in the SR20 engine vs the KA24DE engine. I do know that when calibrating the CAS it will green light for both trigger 2 and ECCS. Any thoughts? This would be huge as we could market this as a unite that would function for guys running dual cam KA24DE turbo cars who need standalone options! Cheers, RichRDE
