Ford MAF's

[Wedge]

Anyone ever used the Ford 90mm MAF on their RB or even heard about this because at around 100$ brand new each it seems to be a good deal compared to used Z32 at 150$ ?

What is the ford 90mm rated at for hp?

You can make any maf work so long as you have an ecu capable of it.

I've heard of poeple using GM 3 wire mafs. Mcfly is right though you can use pretty much any maf as long as your engine management allows you to.

[Wedge]

They are rated ,on the mustang forums, to be good for 800hp ... I didnt know you could use any MAF as long as you tune the ECU to take advantage of it .

You can use that MAF.

Rated to 700hp according to Nistune tuning software for stock ECU, which has the dropdown option to run that 700hp 90mm Ford Ligthning MAF.

Wire it in, change to 700hp 90mm Ford Ligthning MAF in tuning software and tune engine.

On twin turbo GTR with twin 700hp MAF, close to 1400hp at engine or roughly 1050awhp.

1100hp at engine can be done with stock R32GTR ECU -

YouTube- 613kw dyno run. World record for a factory tuned GTR ECU

I think experienced ECU tuner with GTR above 1000hp is key.

So you could use only one on a 500hp GTR ?

[Skym]

Yes...

If you wire the 2x MAF plugs together to recieve the same voltage, you can run 1x 700hp 90mm MAF. This join wires together mod is done on GTS models with 02 sensors, MAF's when running GTR ECU.

Normally with single turbo on RB26 and twin turbo MAF's you run a split pipe infront of turbo from like Greedy/Trust in Japan (or custom intake pipe if you prefer) that can fit 2 x Z32 MAF's.

While i was searching to find info on the ford maf i came across someone on the GTRUK board that runs a hybrid Z32/Q45 MAF not bad he used the Z32 sensor in a Q45 "casing" he said its good for 800hp like the for one but to buy both would be more expensive then 1 Ford unit .

Im chicking it out because i bought a RB26 that is tuned with MAP sensor on a F-Con V-Pro and since no one in quebec province has a licence to tune HKS ecu im screwed . I need to buy a GTR ECU and AFM to make the engine work I was thinking of a nistune and the Ford MAF . Im still checking all the avenues i can take since its going to be a street car 500 hp FairladyZ i dont think i need to have expensive stand alone .

The hp rating is approximate for MAF's.

ECU depends on application. For competition use the more expensive ECU's allow for extra sensors, etc for datalogging suspension, driveshaft speed vs engine speed (slipping clutch), etc. Also can rev engine higher in dragracing applications due to more rpm points. Motec ECU for example has 40 rpm points vs factory ECU with 16rpm points. But with factory ECU, can spread out the last 2-3 rpm points, so instead of every 400rpm, every 600rpm+. The rpm points are where the amount of fuel on fuelmaps or ignition timing on ignition maps changes.

Seems like a very large waste of time transplanting sensors into casings.
The casings are not a restriction in the system simply because they are a big enough diameter for the air they can measure.;)
