Hi, K20A2 with PRA ECU and Kpro 4



Do you have any advice to understand the cause of this jagged behavior of the injection, for example at 3:02

The consequence is that the AFR remains rich for 2 seconds
(AFR on ELD, 0 V -> 9 AFR, 5 V -> 19 AFR)

You can see from the logs that it often happens when I exit from the corner and push the gas.

I attached log and calibration

Thank you
Best regards
Don

Your MAP values also look jagged. Does it do this on the dyno or just on the track?

Thank you for reply.

I done this on track.

MAP is a little jagged also in the next gears, but there is not the same behaviour, you can see log and calibration attached.

It's seems like to me that there is some compensation in fuel.
Could be?

Dwell angle can do this? I have 13.3 Volt at WOT

Thanks

Have you tried making any changes in the Gear Comp tab to see if that has any effect? Such as acceleration smoothing retard?
