I hope that hint is enough

KFZWMIN 1 = 0x12E27 16x12
KFZWMIN 2 = 0x12F64 16x12
Optimum Ignition = 0x15865, 0x15915 16x11 ( two maps )
Basic Ignition Angle = 0x1609A, 0x1615A ( two maps ) 16x12

You are looking for DNWEK. This value is added to KFNWEGM and thus controls fuelcut. Set to 6000, so fuelcut is always disabled when condition AC-on is met you have your pops and bangs.

(You will still need to retard timing aswell)

If you want to change that to cruise control you have to change the bit that is checked for the map decision.

This is a change in program code and needs to be done in every routine you want to change the look up for.

You write you logic with Jump command if Cruise is on.

I can take a look at this if you would like. are you just trying to do the LC pop and bang?

I have the problem on a Seat Leon AUQ. I set DNWEK to the highest RPM (7080rpm) and retard Timing in KFZWMN but it does nothing..... Have i to change any values in KFNWEGM?

The A/C System isn't working, because there is no Gas inside. I tryed some solutions, but nothing is working.
