I'm toying with the idea of moving my AFM to MAF converter from a prototype into a more polished finished version. The short story is that I can't make just one because of minimum order on parts. The smallest practical quantity looks like 4 units. So I'm just testing the waters to see if anyone would be interested in buying the extras. They would probably go for $150 each. You would still need to scrounge up a 3" GM MAF from the scrap yard. I paid $45 for the one I got.

Keep in mind these are experimental and require some plumbing and splicing into the wiring harness to install because I don't have a source for the connectors that mate to the VAFM.

The testing with the prototype showed that converting to a MAF makes a big difference on the 22RE. On my truck, it knocked 2 seconds off the 0-60 time. I don't know if that's the case for all trucks since mine was the only one tested. (BTW: this is for the 22RE engine. I have no idea if this will work on the 3.slow.)

If you're interested, let me know so I can gauge interest in the project.

 

It would be nice to see a finished product for the 3.0... Your next prototype maybe?

 

I don't have a 3.0 around to play with. But the device is pretty flexible. It's just a matter of getting hold of a 3.0 VAFM and mapping its curve. The MAF translator is programmable so it's tuning can be adjusted.

 

im interested . lets see what it looks like

 

A VAFM or maybe a Apexi SAFC..? I'm not sure how cost efficient this will be though.

 

how dificult it will be to tap into the wire harness.and what do u mind on the plumbing part?got me thinking on getting one....
what about horsepower..how much did u gain...2 sec. it's a lot .for the small investment

 

Lemme check my local scrap yards for a MAF, put me down for a maybe right now.

 

You need to splice into the wires that plug into the VAFM and supply 12V to the unit. It's not hard.

The plumbing is something that's in need of some work ... mostly figuring out how to use the existing airbox or fitting it with a new filter altogether. Oiled cone filters are not a good idea since the oil will foul the sensing element in the MAF.

I don't know how much horsepower was actually gained. There isn't a chassis dyno around here to test on. If someone has access to one, I'd might be talked into sending the prototype out for testing just out of curiosity.

The finished unit is a little circuit board that's about the size of a business card. I'm still trying to figure out how to weatherproof it. It might be better to mount it under the dash, but wires would need to be run to do that. (There's just 6 wires.)

 

I might be interested

maybe this liquid tape will help?
or want to use the black epoxy?
or go the cheap way...the rubber diping from harbor freight(the one for hand tools)

 

any progress on this.

 

liquid tape sucks...if you ever gotta take it off?

 

I just found a site the other day that sells universal MAF conversion kits for any vehicle equipped with an AFM. Too bad they're so expensive though. They offer universal 3" or 3.5" MAF sensor conversion kits in the $669-$799 price range. The kits include all the necessary components for a complete install atleast(including the 3" or 3.5" MAF sensor and an A/F ratio meter to monitor A/F ratios in real time). But still, a little too rich for my blood(pardon the pun).

Check it out if you're still interested. http://www.splitsec.com/products/mafkits/MAFkits2.htm

 

updates??

Theirs this but for the price you can buy a complete 7m parts car and still have some cash left over

 

Any updates? Still need people to buy the extras? I have buddies that would probably do the conversion with me here.

 

I redesigned the converter to use the more modern hot-wire MAF from late model yotas, but it hasn't been prototyped to see if it will work.

I still want to make an industrial strength unit that I can leave installed. The first prototype using the older GM MAF produced a 15hp gain +/-. It really did make a difference you could feel.

 

15hp out of a 22RE? Do you have other mods that's working in concert with, or is that a gain from stock?

 

The 22RE it was tested on was a newly rebuilt unit bored .020 over, fitted with the engbldr head, LCE cam and headers.

 

Not bad, you've certainly got my attention then. Keep us posted!
