MAFT PRO and fuel cut

[joeytvr]

I keep reading that people are having fuel cut issues even with there MAFT pro. I have run around 15-16 and have not hit fuel cut. I am runnning speed density, is that why? Does running speed density get rid of fuel cut?

where are you reading these things?

The MAFT Pro has a feature that limits the airflow reading sent to the ECU, you can choose to set it at whatever you want, kind of like an adjustable FCD. I don't have mine on, you can choose to turn it off. Right now with no tune it hits FCO at 11psi or so, but that really doesn't mean anything, because i'm not on the stock turbo (sp61gtbb (newest version with big compressor housing (4"inlet)). That is also with the AFR tracking off. my AFRs are going to about 10:1 so i have some leaning out to do.

Note that Fout Max doesn't necessarily mean you'll never have FCO again. There are MANY parameters that feed FCO. In most cases, a proper tune + Fout Max will eliminate FCO for you.

Also note that FC isn't a bad thing... it's nice to know you're running close to the ragged edge. I still have it enabled on my car.
