I am currently in need of help doing a MAF conversion.
i have the A9l computer so i can tune it with my hardware. I need the Maf conversion for turbo tuning purposes. Its mainly a street car.
The engine is swapped into a former v6 mustang.
Can i Just re pin the truck wires around on the ecu ?
Do i need the GT foxbody harness?
And then solder in the maf ?
.no i will not buy a conversion kit.
What motor are you working with? The A9L does not support boost so I'm not sure how much a MAF conversion would help.
Starting with an SD truck there are a bunch of wires that must be added and some more to be moved to make the mustang PCM plug and play.
A Pimpx PCM does support boost though and it would plug right into the wiring harness you have with no changes.
The A9l absolutely does support boost since it is a maf setup. The maf reads flow .
i dont want to go into this.
i traded my boosted v6 that i tuned myself with the QuarterHorse chip for a 351w v8.
.
So.. im just asking who has done it before ? All i need to do is swap the dash harness, re pin the ecu connector, and solder to the maf signal wires.
Making sure that is it without doing anything else.
But how do you deal with positive manifold pressure?
You need sequential injection wiring too. Here is a PCM pinout chart I made for MAF conversions on SD trucks, colored pins/wires have to move and grey pins/wires need to be added.
That's the thing. It doesn't deal with pressure. It deals with flow. Mass Air Flow.
If the non-turbo vehicle flows 16 lb/minute of air at max .. the turbo will force more air up to 40lb/min (depending what size turbo specs you have )
You tune it by dealing with the MAF Transfer, Injector high slope, low slope, breakpoint... And of course ignition timing under boost. Add a bigger camshaft and now you have more of the ECU to tune.
anyways.. i'm going to get started on this wire project. Thanks a lot for the lead. Will be interesting and kinda fun. Knowledge is power... horsepower. haha.
Interesting. I have only ever dealt with 1 forced induction setup and it was a MAF mustang. This car used an FMU to increase fuel pressure relative to boost and a separate ignition controller to pull out timing, no tuning was used as I don't think the Tweecer even existed at that time, but even so this ran surprisingly well, it made gobs of torque.. enough to break the tires loose passing cars on the highway and didn't blow up.
and didn't blow up.
