Re: Fox body OEM MAF comparison
On my datalog I show about the same HP as the maf shows in volts. My MAF is off a 96 corba 80 mm I thinks'
My dyno is to the wheels and that one may be from the crank. If so then its dead on. Pretty cool info. Lot's of information on that site. Thanks |

Re: Fox body OEM MAF comparison
Yep, that's Joe Viola - (stangPlus2birds) from corral.net. Joe is some type of engineer, and actually works with flow meters for a living. You should see some of his posts ripping people who don't know jack about MAF and EEC stuff!
He has numerous OEM ford EEC's, tweecer, eectuner, etc. He actually built his own flow bench for MAF's, which is where those numbers came from. He's prob. tested 100's of different OEM MAF's, etc. Unfortunately, his delivery in his posts leaves a bit to be desired, and he usually makes people mad at him to the point where they don't believe him.

Re: Fox body OEM MAF comparison
Yeah, Joe can be pretty harsh.
He hammered me on the TPS the other day. Smart dude though. I think the end conclusion on the use of a cobra meter has to consider the required use of the computers adaptive ability. Since we only have 12-15% adjustability with the fox computers, it may not be a good idea. The posted graph show that the difference between the stock MAF and Cobra MAF can exceed 24%. Besides, do you really want to design in significant amount of error in your system? If one has access to a tuner and can change the MAF Transfer, then there is no real downside. jason |

Re: Fox body OEM MAF comparison
Exactly.
I'm still unconvinced on the TPS voltage thing (for those of you wondering, Joe contends that as long as your TPS voltage is under 1.25v, the EEC zeros out the reading at startup to 1.0v every time, just like the 94+ cars. Probst book says so, but I'm not so sure whether it was a typo or not). We all know the EEC wants to see 1.0v or less, but the engineer in him won't let it go, so he throws that out there for the masses. Prob is that the masses isn't ready for that, and confusion ensues...

If anyone can find information whereby 1V is used as a reference, I will be glad to admit I'm wrong (unlike annoying Joe). |

Re: Fox body OEM 5.0 vs Cobra MAF comparison
Apparently I was reading the GUFB document correctly
This is one of about 3 or 4 oft repeated EEC IV "facts" that I have found to be untrue after reading much of the GUFB strategy document this past week. |
