Once warm press the throttle and relase the idle goes back to normal, but when engine is loaded, press throttle and relaese then the idle goes too low.

What are the step to adjust the IAC PID ? I do not understand clearly the combination and effect of these parameters and the documentation is very limited on that topics.

Many thanks in advance.

Laurent.

I have some question when the difference between afterstart and warm-up is not so clear and also deadband meaning.

I encounter some difficulty to understand some of the parameters.

Is their a good VEMS user in France around Paris for brief advice ?
