Title: Ignition Retard Cylinder 3, a3 1.8t Post by: ottosan on July 23, 2018, 03:53:48 PM Hello,
I'm having trouble with ignition retard on cylinder 3. I have tried to swap the injectors, ignition coils, changed spark plugs with no luck... :'( It would be great if somebody could tell me, what is possibly wrong? I'm attaching CSV logs and ECUx screenshots. Thanks in Advance, Title: Re: Ignition Retard Cylinder 3, a3 1.8t Post by: gman86 on July 23, 2018, 06:21:20 PM Check the cylinder isn't ingesting any oil.

Individual cylinders can knock sure... My question was what could be possibly wrong with that individual cylinder. Title: Re: Ignition Retard Cylinder 3, a3 1.8t Post by: adam- on July 25, 2018, 03:25:35 AM I don't get your question. It's knocking. Add fuel, less boost, less timing.

I can't count how many times I've seen nyet say "can you actually provide logs so we can HELP you!?!?" The guys forehead must be just absolutely thrashed at this point from facepalming so much..

Title: Re: Ignition Retard Cylinder 3, a3 1.8t Post by: royce5950 on July 25, 2018, 04:45:45 AM did you ever think to reflash to stock and then record a log to see if anything is different to rule out whether or not its something that you possibly did wrong in your calibrations that are causing the symptoms your experiencing?

Hello royceV3PT, I assume stock file would not work as I have upgraded the turbo to TD05h-16g. I have calibrated another turbo upgraded(CT-20b) a3 with the same engine code but only with less km. Air mass consumed by the engine is about the same @ about the same boost and here is the log from that vehicle. :) As you can see ignition is not retarded at all. Taking in consideration all mentioned above I assume that, something could be wrong with my hardware. But what? Sure, none of you could not knew the background when writing your answers to me. Still waiting for your opinion... Regards, |
