Strange dips in Injector Pulse width?

Post by kim_gulle »

Hi everybody!

I am currently helping a friend with his car. It runs fine, but sometimes when just driving around, the injector pulse width suddenly drops and the car jerks once.

My theory is that something is screwed up with the AE. More specifically the Decel Fuel Amount(%). It is, for some reason, set at 50.
Now, i have yet to test the setting of 100 on the car, since i have been analyzing the log just now. But could this be the reason for the drop in pulse width?

If i look at other tunes, and also the basic tune that comes with the firmware, this setting is at 100. Don't really know why this is set to 50...

Provided is the Log and the Tune, compressed into a Zip. It's running the hr_11d code.

Thanks.

Yes, that's the decel fuel cut; I would set that number to 100 to disable this.
