How do you dial this out? Around 1500 very light or no throttle and dam have to dip the clutch before there is an inch of play on every splined shaft in the drive train
It's not the over run as I moved that to eliminate it.
It's not the transition from moving to stopped again moved to eliminate

In short, learn to map properly.

Have you tuned the injection angle?
Have you calibrated the TPS properly?
Have you set the idle load threshold so the engine isn't trying to idle when you drive it at light throttle?
Have you set the over run fuelling and also the closed throttle detection so it's no fuel cutting while you're driving at low throttle?
Have you mapped the fuel map so that you're running a sensible AFR at light throttle?
Have you set up the transient throttle fuelling so small adjustments to TPS at low load don't flood or lean out the engine?

We all start some where pav and hence the username
Cheers for the pointers

But what you're posting about is actually one of the more difficult aspects of mapping. If you've come from doing opensource oem stuff to this, then there is a lot to learn.

Set your injection angle to 360deg if it's set at 540 that move alone will help.

If you want the engine to run nicely at 1500rpm and at some specific MAP you will need to test it like that, steady stead or at least not just measuring the lambda as it drives through it in a split second.

Sounds like you're going in and out of idle and that could send the ignition timing up and down massively causing your issue.

Don't mind paying experienced mappers I just like to learn.
Zen or gr are on my radar
Yes got 360. Early days only had an hour on it.
Terminology and ui are all to learn to moving from different software/ecu's
Lots to learn in general
Cheers again pavlo

Are ALS strategies disabled or have you fuel cut if ALS is OFF?
