Hello, i have buy the UTCOMP PRO.
I need to know what a and b by the air fuel Ratio Mean I have a Lambda gauge from England Who Shows 0-5V 7.35-22.39 AFR But i want to show it in Lambda ( :14.7 ) i have actualy a=0.21 b=0.5 it is verry close but not exakt.
I have on the digi out unser a Verry Bright led and i want to Use it as a shift light. I have the RPM Signal from the injection valve and from the camshaft position sensor.
I have a few other questions but These two are priority.
Sorry for my bad englisch and thank you for your help.

Re: Lambda Wert kalibration and Shiftlight
7,35 - 22,39 AFR for 0-5V gives a=3,01 b=7,35 - it's for AFR
If you would like to have lamba just select in settings -> advanced -> afr/lambda -> select lambda a=0,204 b=0,5 . You can calibrate b (e.g. 0,49 or 0,51) if you have offset voltage on wires.
You will need external shiftlight - dig out user is only for low frequency signal control (1Hz per second) and RPM based on injector is also slow.
