When asking for technical help at the very least let us know the version of firmware you are running.Cliff's Calibration (Mapping) Guide is a MUST READ: http://www.vemssupport.com/forum/index.php/topic,97.0.html

It means that there is a 2.5% duty cycle change for every 1000rpm of error there is between rpm and your idle target.78 would mean that there is 5% change for every 1000rpm

So I should use IAC lock and watch duty cycle at 1000rpm and then 2000rpm? Then I should find a difference between it and divide by 2,5 and multiply by 39? Then it would be my P value?
