Rb20 Problem Solving Help.

[mwracing]

Hey I have a question regarding the MAF's on a gts.

If you had this setup being installed.... how would you control the MAF.. like upgrade to z32 maf?

not really sure what to do because we are going for about 250-300kw.

Stock RB20

Plazmaman Huge intake plenum

FMIC kit

Greddy BOV

garrett t04s 60-1 turbo BB

Top mount t04 manifold

650cc injectors

Walbro 255

greddy metal headgasket

arp headstuds

HD clutch

E-manage

3" test pipe

3.5" Cat back

3" custom downpipe

HKS Wastegate @ 15psi

Can the e-manage make the stock MAF work for this kind of HP?

or what do i need to do for the MAF situation...

I would swap the emanage for a remap with a z32 AFM, and use a bosch 044 fuel pump

if the afm is maxing out you can use the pressure sensor with the emanage, you can clamp the maf signal of the afm when it maxes out and then use the map signal from the pressure sensor. emanage has this feature.

this is only if your afm isn't currently creating a big restriction in your intake, which it probably would be with the power your chasing. which you could then look at the z32 or q45 afms. which will work with the emanage. or even a afm bypass, but i haven't seen this done with an emanage before, only full aftermarket ecu's.

thanks for the suggestions..

what did you mean by i can Clamp the maf signal when it maxes out and then use the cap signal of the pressure sensor?

It can read two at once? or one after the other?

buy clamp the signal i mean it locks the signal voltage at a little bit lower than the max voltage. so the ecu doesn't think its maxed out and hit cut. this makes the ecu output enough fuel and timing to run it at say 95% air flow. then the emanage will use the map (mass air pressure) sensor to take its reading from, and you have to tune it for the extra fuel and timing you need for anything after this point.

so its like what you said, it uses one after the other.
