Working with ME7.1 on a 1.8t AWP HS box

I recently swapped my ignition system for an LS2/Yukon coil system consisting of spark plug cables and adapters to plug into the OEM harness. Does anyone know how the ecu measures Ignition circuit malfunctions? I'm now getting:
P1355- open circuit cylinder 1
P1358- open circuit cylinder 2
P1361- open circuit cylinder 3
P1364- open circuit cylinder 4

I'm looking to calibrate these maps to the proper signals for the coils and not disable the diagnosis function entirely.

Because using the RED Ngk ones is too simple...

I just want to know if this is the car that melts plugs.

I installed the LS2/Yukon coil pack ignition system on 10/05/16 at 11am. All time prior to this time, the car was operating on engine code AWD hitachi bolt on coil packs. on 10/05/16 at 6pm I got the idea to check my spark plugs BECAUSE: over the past 6 months i've checked and gapped my spark plugs 4 times. At the beginning of this time period I was running OEM (but not OEM labelled) NGK R PR6Q platinum resistor plugs as defined by the bentley manual. Checked and gapped the plugs to the required spec (.025"). After 2 months, misfires on specific cylinders and random multiple cylinder misfires. Replaced coils on specific cylinders and rechecked plugs. Gap is now .040". corrected gap back to .025". another 2 months goes by. more misfires. replace more coilpacks, check plugs again. again, gap is .040"

I am fed up. I replace plugs with NGK R PR6Q OEM LABELED plugs and gap them to the required .025". replace another coilpack. Not sure if coils are dying, or what else is going on so i plan to replace my ignition system with the more reliable LS2/yukon coil packs and cables in order to rule out that my coils are dying off. Finish this and sit on it because i'm lazy and don't want to install it.

 2 more months go by and i'm getting HEAVY misfires and bad circuit codes from cylinder 3 coilpack. replace the pack, look at wiring harness which was replaced 6 months ago at the beginning of this escapade. decide to replace packs with Ls2 packs finally.

That brings me to 10/05/16 where I pull the plugs and the tips are missing and the gap is .050"+
So tell me, if my plugs have been burning up and I put the coilpack system yesterday, how could that be the cause of my plugs burning?

So, back on topic. ESKONF would disable circuit diagnosis correct? That is NOT what i am looking to do, I am looking to understand the method of operation for circuit diagnosis so I may increase or decrease it to make it suit the new LS2/Yukon coilpacks. Does it measure voltage to the coil or resistance through the coil? Does anyone know this?

Where would I start looking in the FR?

Circuit diagnosis is performed by the ignition driver.

There are no circuit diagnosis maps.

What is an ignition coil driver? is it a series of components built into the ECU or a separate module somewhere else in the car? Is it hardware or software or a circuit? is it built into the coils?



From this diagram, it looks like it's built into the coil. assuming driver is the same as "igniter"

circuit diagnosis parameters are determined somehow by software programmed into the SOIC20 microprocessor, assuming it's a microprocessor. Any way to access that software? It's just curiosity by now, odds are I will deem it too much trouble and ultimately disable ESKONF ZUE

11'ed the bits for ESKONF ZUE. Worked. I'll report if I find any ramifications.

You can delete this thread if it serves no purpose. Found the answer. Thanks Marty
