Need ecu N351 circuit info...
Hi guys, is there a link or thread for ecu N351 circuit description. Reason is I have 2 that have burnt circuits. One from my car the other I bought off ebay that was burnt . I just want to see which circuits are burnt to see if it's relavent to driveability. Don't want to buy another damn ecu. Thanks.

I know ecu's are usually the last thing to go. One got fried that was the original ecu for the car. The other was off Ebay that was apparently fine from a running car. Oh well will have to keep looking.

Start the car up and fully warm it up. Let it idle at approx 750 or so. PUll the BAC plug off as it idles. Listen to see if the rpms change to a lower reading. Reinstall the BAC plug and listen for the rpms to rise and maybe chugg for a moment before settleing down. IF you have a idle that is above the 750 figure, well just forget about doing the above til you have a real idle.
IF the rpms did not change when you did the above, I'd suspect the BAC circuit is shorted to gnd or the wires on the BAC to each other.
If the rpms did change, then look for a shorted Port Air solenoid or Split Air solenoid on the ACV. The wires to them, not a internal short in them.
