has anyone made a home made maf i found a maf on ebay and i think its a home made one how does this work. does anyone have a write up on how to install a maf. what wires go where.

i have been trying to see if i could get a maf out of a different car and make it work in my 951

You'll find a writeup on MAF installation at Lindsey Racing.
here u go:

Rather than the harness signal return, I wired my MAF ground to the ground near the test plug where typically people get there 12 v power from.

thank you

but has anyone made a maf kit with a maf out of some other car

Huntley used a MAF sensor from an old mustang.

now we are getting somewhere where can i find more information on that

Dude, no offense, I am not sure of your car tuning experience, but if you are not real careful or know someone who is experienced w/ tuning, you are looking at a costful lesson. IE engine rebuild. The A/F mixture is critical. I am learning more and more the few years I have been here. I had a 300zxTT a few years back which was much easier to tune since it came with a Mass air sensor rather then mass air meter. Best options are in no oder of preference. Lindsey, Maxx (Russell),Vitesse,SFR. You will need to have a WB O2 sensor, preferably that will datalog ,at a minimum.

I am currently getting ready to install SFR MAF, and will probably contact Russell to tune after seeing how it does w/ my current Guru chips.

Hope this helps

i get where your coming from but a maf is a maf as long as you can hook it up right and get a stand alone unit like the one from LR then it should not matter where it comes from.

Do some more research. By the time you cobble something together and wind up with a substandard outcome you can spend only a few dollars more and get a decent product. Lots of people here have tried the diy route, there's a reason for there not being a write up on this. Every so often someone new comes a long and claims that they're going to do this and then........

Ya these places arent charging you a butt load for a maf. THe prices are really decent for the piping, couplers, Rewired connection, air sensor and K&N that you get from them. Then you need the piggy back anyway. So you could in theory maybe save a couple bucks on a used maf and have a used maf that doesn't read air acurratly. Go to the 928 board where the 85+ cars all have MAFs in their car. Half of their troubleshooting is no knowing if the MAF is readin perfect. They all send their MAFs our to get a rebuild to 'tune the car up'

Hi,

I have attached a typical MAF which most of the cars use. The sensor element is always the same, but the airmass throughflow depends of the diameter of the MAF. The problem is not the sensor, but the transformation from volumeflow to massflow, which is normally done by a electronic piggyback computer.
Instead of using a MAF, you could use a MAP sensor, which is easier and better than a MAF and it can be done without a piggyback computer only by reprogramming the DME.

this, is a long journey of reading, learning, more questions; reading, learning, more questions. I tooo posted something like this a while back. while it will work with piggy backs....I have a mafterburner 4 sale by the way (shameless plug) There are better ways, but way More costly.
