Title: 5.0 Mass Air conversion on 2.3 turbo?
Post by: JoeNoble on July 20, 2007, 04:32:16 PM
I bought this plug for my 5.0 mass air meter for my turbo 2.3 but I'm not sure which wires on the plug go to which wires on the factory wiring. Can anyone help?

What other bits do you have?  You're not just going to plug that in in place of the VAM and have it work.

I also have everything I need to upgrade to a 5.0 throttle body but need to have my intake port matched and I’ve got 46lb injectors, a new fuel rail (OEM), and an adjustable fuel pressure regulator. But I want to put all that on together and like I said I need to port match my intake manifold.

Some way to convert the signal from the MAF into something the turbo ECU can even use.  They are not the same.

If you look at the wiring diagram for a car with a MAF and a car with a VAM they are totally different.  Its not as simple as changing the connector.  A MAF is treated as a stand alone sensor, a VAM shares wires with other sensors.

you will need a moates j3 adapter and someone to burn you a chip with the maf  tables.

That sounds nice and expensive. Thanks bro.

Are there any mods for the ford 2.3 that don't require ecu modification?

I was told as long as the mass air meter came off another turbo engine that it'll work but my question is were there any turbo fords that came with a flow through maf similar to the 5.0 maf? I found a few on ebay that say they're probe or merker turbo mass air's but can't tell from the pics if they're flow through’s.

Post by: Chuck W on July 27, 2007, 10:23:50 AM
Merks use the same VAM as every other 2.3T.....

Not sure about the Probes...but the engine is smaller...so the air meter is not going to be any use regardless.

so is it just not posible to upgrade my maf?

I know the Tempo 2.3L came with mass air. Not sure if that helps any as there weren't any turbo tempos that I know of.

Yeah, its gotta be turbo. thanks though

You're not just going to find one and bolt it on and have it work.  Like I told you already the outputs are different and you have to have someway to covert them. 
Either one of the py piggyback coverters that were offered and never worked right to begin with or some sort of tuner (EEC Tuner, Tweeker) that would allow you to alter the code in the ECU.

You have a VAM (volume) not a MAF (mass). While they might serve the same function they measure air in different ways. Start thinking square hole, round peg and the sawzall is the tuner. You need to sawzall that computer! :D

That doesn't matter. YOUR computer won't know the difference. You need a tuner of some sort. Unless you find a 2.3T w/ MAF then take the MAF and the CPU and everything else because it doesn't exist. Well, at least not in stock form. Actually there was a guy selling a MAF setup. Check the classified forums.

And whoever told you a turbo MAF would work on a stock computer is wrong!

What he said. Again. No tuner, no workie.

As for other upgrades, I would go with a T-3 if you don't have one already. Actually what mods do you have?

it stock right now turbo and all. I baught a 5.0 maf (but had no idea it would be so much trouble, probably more than its worth), 46lb injectors (need to get mega squirt or something similar), a 5.0 throttle body and the adapting equipment (just need to port match my intake.

Post by: Chuck W on July 27, 2007, 12:40:36 PM
If you're looking at MegaSquirt..then you need to read more.  if you had you'd of realized that you don't need the MAF sensor.... ;)

You could also use one of the aforementioned tuners to tune for the larger than stock injectors if you HAVE to have the MAF.

What about the later Rangers with the 2.3 and 2 plugs per cylinder?  Were those Mass Air?

It makes NO difference.  NO 2.3T ECU was ever available with mass air, so it would have no idea what to do with the signal.

I can understand that aspect, but would it be a worthwhile endeavor to use the 2 plug head/ECU/harness end other necessities and put a T04 on it?  Just curious....

Again, not worth it or even really feasible without some sort of tuning capacity.
