I hope some of you guru's can help me, i've had 3 naspy Mr2's before.









its a rev 1
with a rev 2 engine and ct20b turbo.


now, its got all the wiring from a rev 1.


and the ecu is from a gt4 st185, and runs fine.





however.


the problem:
when you rev the car past 1400rpm the ecu light comes on.





i originally thought it was the wiring for the knock sensor to the ecu, now i've ran a wire from the knock sensor to the pin on the ecu and its still doing it.


we've tried 4 different knock sensors in the car in the last 2 weeks lol

its currently got a gm knock sensor in courtesy of woodsport
