It would be nice if the nice people at Durametric would come up with an iPhone / iPad version since its a PITA having a 17" MacBook Pro in the driver's seat to get Actual Values.

I can do the .NET -> iOS conversion if they dont have anyone
Good luck with that. They don't even have a mac interface.

No.

A maf is an analog sensor, NOT an on/off switch.

Reading values it is reporting to the DME is only part of the story- the values tell you it isn't 'dead' or blown.... But you have no way of knowing if 1.35V is what it SHOULD be reporting for that airflow rate!!!!!

I'm not saying it is bad or it is the MAF, just pointing out that you cannot rule it out

Was that a serious question?

AFR = lambda value of O2 sensor * 14.7
