Ecu Error Codes

[feyd182]

I dumped the codes from my ecu and got 21-ignition circuit, and 11-crankshaft postion sensor. My #6 cylinder does not seem to be firing at all, the voltage coming from the ignitor on the #6 lead is only 0.73v @ idle. I've tried different coils, plugs, ignitors, and crank sensors, even the coil harness as well and the problem persists. My question I guess would be is, would my ecu be f**ked? Would adding something like an E-manage help correct the problem, or should I try to get another ecu. As a side note, I recently converted my RB20DE to an RB20DE+t if that would have any effect on the problem. I did by the way upgrade the injectors to stock turbo ones, and the stock ecu from DE to DET. My fuel press. at the rail is approx. 38psi @idle and approx. 45psi under load. My turbo seems to be able to hit 12+ psi with no problems, although anything over 7psi and the engine starts to burp and fart.

The DE is a much higher compression engine than the DET - you DO NOT want mega boost running through the engine, 7psi should be heaps. Over 7 it is probably preparing for detonation heaven.

To the coils - have you swapped the #6 coil with one of the others, eg#5.? What happened?

Found the problem after swapping every component out and having no luck, the injector was stuck and flooding the shit out of the cylinder coupled with the fact that the #6 lead on the injector harness was hatched as well. I swapped out the injector and harness for #4,5,6 injectors and no more problem. I also turned off the correct on my afc-neo and it cleared up even more. As for the knock sensor and crank sensor, all I did was add an extra ground to the crank sensor and that problem disappeared as well.
