Title: Question for people with a power FC
Post by: phat purple one on December 11, 2010, 11:50:03 PM
Hi all,

I was wondering if someone could tell me what the MOP reading on their FC live data shows? Mine shows 0.83v contant, and is overfueling. I\'ve read somewhere that the power FC ignores this signal, is this true? Or do you think that replacing the meter oil pump would cure my fault.

Any help or information would be much appreciated.

P.S. Its a gen3

it should increase voltage with throttle position.

i think mine goes to around 1.23v(havent looked in months) when theres some light accelaration

Cheers though it was wrong, Any idea whether the power FC ignores this signal or not?

The PFC does not have a limp mode like the standard ECU does.
It would not cause it to inject more fuel.
I think the MOP voltage is highlighted if it is out of tolerance and your heatlight comes on, but don\'t quote me on that.

^^this, it gives an indication that the MOP may have / be in the process of failing
