Having a play and runs real good but

When I'm coming to a stop the motor either stalls or idles very low (about 660rpm)

As soon as I'm stopped it picks back up to normal idle speed, even did a 10 kph restart in gear and started and idled just fine.

Seems to be worse at higher engine temps.

Havn't touched the idle, warm up, or IAC maps, maybe I should. Have lowered the Decel back to std as no longer any pop

What have I done and how do I undo it?

Thanks Scotty, I'll have a look tomorrow.

No issues Dazza, did get a few ideas off em that have worked to good effect on my old map.

Is there a way to test the TPS Sensor?

and is replacment just bolt off, bolt on, plug in or is Digital tec required to set up?

Problem solved.
Did some more 14.6 AFR runs and used the VEs generated from the last batch as the base for MyTune to work from.
The first lot of runs generated 3 dozen changes, 10 of 15% or higher the largest was 22% @ 1250rpm and 0% throttle.
Todays lot of runs with the updated VEs and timing made only 14 changes with a highest of 8% and most were low revs and 0 throttle.

Lesson for the day - If MyTune makes large changes, keep doing more runs and more updates.

Most likely be the same for any similar soft ware based tuner just mine stands out because of the stalling.

Still reducing Decel Enleanment, trying to make it pop then I'll go back one step. Like em rich on roll off, good for ring/piston life.
Need to fine tune Cranking fuel as well, but its close.
