Cobb v3 reporting 'ECU' fault code after uninstall?

chrono · 08-20-2014, 08:55 AM

Hey all,

Cant find any info on this fault code (of course its damn near impossible to search for an 'ecu' ecu fault code...)..

Unistalled my cobb v3 a couple of weeks ago and just hooked it back up now to scan for codes and ive got 2

-misfire cylider 4. not concerned. had this even before the uninstall. need to change my plugs.
-a code that just says 'ECU'

So the ECU one is concerning and I can't find any info on it. Is this some sort of 'shadow'/tuning code? Is my ECU blowing up?

I have seen this, its nothing to be worried about IMO. One fault code can trigger another, it doesnt mean there is an initiate problem with a particular hardware the fault code shows.

The first thing you need to take care of are the plugs and or coils. This is more likely the main culprit

This is just the ECU doing its job by intervening to a serious threat, so thats why your are seeing an ECU code

Ok cool thanks. Yeah I need to order a set of plugs to start and have them installed. This florida heat is definitely not helping the missfire situation!
