need help on installing the z32 MAF on the sr20 (redtop)

[implict]

Came with everything, as in filter and wire harness.

Thanks, Jeff.

What exactly do you need help on? Is your ecu tuned for it or do you have an afc or etc? Iv'e seen a lot of threads lately on this. Do a quick search on z32 maf.

[implict]

I dont have a afc and my ecu is stock. I just wanna know how to hook it up.

[Tai Mai Shu]

You cant, they run on different voltages, go out and get yourself an AFC mmmk?

[Drakon]

you gota tune ur ecu when you get the new maf cause your ecu will be thinking its still the stock one and it wont work right.

[robbbby]

I think he is asking how to wire it up, not how to tune it?

[implict]

well... i want the thing to work... as in i got a MINES ECU.. and no afc controller.... didnt know i needed one... so i have to get the afc controller?

If your mines ECU is tuned for a Z32 MAFs which is proabably isnt, then you could run the ECU. I have a picture on what the pinouts should be, but due to the limitation of the board I cant post it.

Huh? Limitations? I thought this board was all about sharing information and helping each other out??

[implict]

wha???? no idea.. what limitz?

[SpeedRacer1]

I have a picture, but the board will only let me post a 300 x 300 pic = gay.

Heres a link to another guide by JWT, try to firgure his out...http://www.sr20development.com...F.pdf

So you can't adapt a different MAFs into a SR without modify the ECU? What If I I use the AFC instead of modify my ecu, what do I need to set in the AFC? Also, what is the difference between a cobra or a 300tt Mafs to a SR one?

[ItzGenX]

Bigger...

[implict]

so if u get a afc... u dont need to mess with the ecu?:help

[robbbby]

I'd think using a afc would be considered messing with the ecu.

[AznRide]

Let me get this straight.

MAFS tells the ECU to let the car consume more air.AFC makes the ECU let the car consume more air.Therefore, AFC controls the air, so what the hell is getting a bigger MAFS do? I understand it's bigger, but is this where the difference of size comes in and play a major role in air/fuel mixture?

MAF's tell the ECU how much air the engine is consuming.

SAFC lets you modify the the signal of the maf, therefore tricking the ECU into thinking your letting in more or less air then it really is.

bigger MAf alows more air flow less of a restriction. the standard MAF can only read up to a certian amount of flow after that the ECU thinks its only gettin a set amount (the limitation on the mAf). but a z32 maf has differant voltage and out puts. thus you need a burnt chip or AFC to translate the maf signal into somthing the chip can read.

well i think thats basicly it !

please correct me where im wrong guys !

[AznRide]

So if changing the mafs. you need an AFC or programmed ECU to make it work right? If not, the car won't start up?

[implict]

it will start up but the new maf will will be useless.

Tell me if im wrong

[slw240sx]

it would prob be like running no maf or a really really out of wak maf leading to mixure problemns that could be detrimental!

yes you need a AFC or a ECU remap!

[implict]

k thanks alot.

Jeff.

Anyone have a afc laying around ?:D

[badass240sx]

Following the subject, can you use the MINES ECU in addition to the AFC to say switch to the z32 mafs, and bigger injectors? Or will the ECU not wire up with the S-AFC?

[implict]

i dont think the mines ecu is tuned for the z32 maf... So far from what i have looked up, you do need the afc controller. Inless you go get ur ecu tuned for the z32 maf.... up 2 you.

[badass240sx]

No, im asking whether or not the S-AFC will wire up and function correctly with the MINES ECU as it would with the stock ECU allowing me to change MAFS and injectors.

[SpeedRacer1]

I dont see why not, the Mines ECU (if it was weakly tuned) is just a regular ECU that has had is speed limiter and electronic limiter cut.

[implict]

it should.
