Re: AFR peak at 4900 RPM

Hi, On the sensors tab the injector ms value decrease at that point(490 rpm). Does your torque peak theory explain this? If you graph knock retard vs rpm you will see that at the same rpm(4900) graph starts to show knock retard.(I dont know if they are corraleted) If you are %100 sure that the fuel ...

Re: AFR peak at 4900 RPM

Hi
I have corrected row 4300 as you have stated. AFR around 4.300 got richer but the AFR peak (lean) at 4.900 rpm (WOT) still exists.
You may check the attached files.
Are you sure that this is not related to a software issue.

Re: AFR peak at 4900 RPM

By the way the AFR peak that I am talking about is at 0:22.
What I am trying to understand is that there is a software bug or something.
Thanks

AFR peak at 4900 RPM

Hi, I am uploading my calibration and datalog. There is an AFR peak at 4.900 Rpm that I can not understand. No matter what I did, I could not make that spot of the AFR line flat. At 4.900 rpm; on the sensors window INJ value goes down opposed to Fuel Low map. It is like the Ecu is using another valu...

Re: False knock or not?

Thank you very much for your answer.
Than I will load back the stock low cam ignition table and leave it that way. For the knock sensitivy low table what value should I set? It looks like 100 will be enough or should I go up to 204 like the first 3 columns

False knock or not?

Hi, My datalogs show knock counts at low cam with stock calibration. To understand if it is false knock or not, I reduced the ignition timing by 2 degrees at ignition low table. I have got again knock counts mostly between 2500-4000 rpm and %20-%30 throttle. My car specs: Model year 2009 Euro spec D...
