Quick MAF ?
#11
RE: Quick MAF ?
There are MANY applications that use them...
The 94-95 Mustang being the most commonly known.
I have also found them on several Lincolns, especially 4.6 motors.
For this item, a junk yard can't be beat.
At my local pull a part, it's about $18 for one, IIRC.
If you do a search for '70mm MAF upgrade' both here and on the stangnet, then you should find MANY of the most common vehicles...
What you are looking for is the 70mm housing, with the 'F2VF' sensor.

Do you know any of the problems that may occur if I were to keep the MAF I have and the 19lb injectors? I'm going to buy a 70MM one, but I'm just wondering what some of the problems that could occur. Just curious.

The motor would probably have rough idle, and would likely be prone to low speed bucking.
Detonation would likely be an issue at higher rpm/loads.
I'm just speculating though... never considered trying it [8D]

RE: Quick MAF ?
I do have the rough idle problem, that is kind of what I was thinking in the first place. If I put the 24lb injectors in, obviously there would be too much fuel. I do have a fuel regulator and gauge, could I turn down the fuel pressure? I know the best thing to do is buy the MAF, I'm just trying to figure out what happens when you do something.

The major problem with this *could* be at idle... as the ecu would have to command a pretty small Injector Pulsewidth in order to get a stoich AFR.
Injectors don't control very accurately at lower PW's, so the AFR can become erratic... which leads to idle stability issues.
You also have the variable of the C&L MAF meter, which can cause issues itself...

Same applies for increasing the fuel pressure... The injector will act like a larger unit, spraying more fuel per PW, but if the pressure goes too high, control issues can occur.
I am not sure what the fuel pressure limits are though, so I don't know what pressure settings will start to cause issues...
If you decide to play with the pressure, then I suggest making changes of 1-2psi at a time... take it for a drive and give the Adaptive Strategy time to figure things out. This means 1-2 Hrs of driving, making sure to hit cruising speeds, idle, and mild accelerations. (WOT won't impact the adaptive settings, so it can be avoided)
