My late model MAF sensor came in. Got it off of ebay for 30 bucks and it appears to work so its not too bad a deal. All I can say is this thing is friggin huge! The opening is about 3.5 inches across. Lot more flow capacity then Ill ever need. Should be interesting to tune it. I dont ahve the tables for this sensor so Ill have to use the BLMs and forcasting to rough the tables in. I cant wait to try it out.

A few pics...

What I did, was take a 3" housing, and cut the foil out of it, and then ran the 3.5" sensor's guts, in the small housing. Had to trim a few locating nibs, but no biggie there.
BTW, they read down low enough that a lil 231 meters fine on them.

Remember you gotta match the freq range of the sensor to the ecm in use.

 

Im going to be using a frequency to voltage converter so I can easily read it in with my tbi ecm. Seems like the easiest way. From the tables I have the resoultion is ok at low flow rates but it gets bunched up above around 200 grams/sec or so. Ill probably use a venturi adapter of some sort so I can adapt the smaller inlet of the tb hat to the rest of the larger plumbing. Id like to ultimatly make a custom tb hat that has a large 3.5 in opening on it. Should be able to easily feed whatever I throw at it.

 

These are good sensors now that you mention it. I dont know why people havnt made more headway with using them in place of the standard mafs. Some of those guys running minirammed 383's and 400's could really use it
