Megasquirt Idle PWM settings help

Hello, I have installed a Megasquirt 2 ECU, V3.0, with MS2Extra firmware, in a carburetted engine the engine operation settings are correct and it has had an excellent improvement in fuel efficiency as the carburetor has been replaced and ignition conventional by injection and electronic ignition.

Now I have a configuration error in the activation of the idle valve, when the vehicle runs downhill and I stop, the engine shuts down, I have tried to configure the injection cut in parallel, but I am unable to know which configuration can correct this error, this only happens downhill and apparently when the injection cut is activated as a whole, because when I drive flat or uphill it works normal, the engine does not turn off and works correctly.

I enclose the closed cycle PWM idle valve configuration, with the initial table, the engine idle speed (RPM) table with temperature and the main fuel map.

Can someone give me a hand?

Thank you...
