Bump for another really weird question. I adjusted the scaling and latency around and have it driving nice most of the time. I overshot my cranking/warmup enrichment adjustments so I gotta pull them back a hair it doesn't like to start hot.

The weird question is are there any vehicle speed based idle compensations?

If I'm idling at a red light clutch in on the brakes idle smooth 850-950. If I let off the brakes and coast forward downhill the rpm drops almost to stalling. Thought maybe it was due to vacuum changes from letting on n off the brakes but it seems speed related since I tried holding myself stopped with the parking brake and then coasting. Soon as it starts to roll forward the idle drops. Pretty annoying every morning there's a traffic light I sit at with a slight downhill and it does it every time
