lsdengines Posted February 14, 2008 Share Posted February 14, 2008 the stock 93 cobra maf was 70mm. Quote Link to comment Share on other sites More sharing options...
lsdengines Posted February 14, 2008 Share Posted February 14, 2008 is there any reason the jwt kit specifies the cobra maf. I ask this because the wiring for it is no different than the other ford mafs. It is just the only factory available 70mm unit for mustangs. Most any of the mafs for 89-93 mustangs should have very similar flow tables values. Quote Link to comment Share on other sites More sharing options...
Bernardd Posted February 14, 2008 Share Posted February 14, 2008 the airflow map in the ecu program has to match the maf, if you used a different maf your engine wouldn't run very well Quote Link to comment Share on other sites More sharing options...
lsdengines Posted February 14, 2008 Share Posted February 14, 2008 thats what I was getting at. The only thing that I know of that is different about the cobra maf is that it is 70mm and has a 24lb/hr sample tube. That is the main thing that changed with the mafs availible for the 89-93 mustangs was the sample tube. I actually know of a few people running a piece of 4" tubing with a sample tube inserted in it on stock pcms on terminator cobras, and they are working well. I'd be curious to see what the jwt map looks like because the ford eec maps are pretty generic. Sorry, going way off topic there, I was just trying to see if there were alternatives to having to use a 93 cobra maf. Quote Link to comment Share on other sites More sharing options...
