Maf Fmu?

[Dangler]

would a used vpc and gcc\safc work?

[Joel]

you tell me, I know jack shit about this stuff. I don't mind used tho, no.

[Dangler]

well i say used b/c they don't make vpc's anymore.

Are you looking to go from mass air to speed density and then adjusting your fuel?

Or are you looking to adjust your fuel only?

This is on a turbo probe? Have you talked to Fallguy?

[Joel]

I am just looking to change my fuel settings. I haven't talked to matt, since he isnt an avid poster, I have a hard time getting a hold of him.

Changing your fuel should be easy - can you confirm what car\motor it is? You can change the fuel w/o getting rid of the MAF, just intercept the signal to\from the ECU with and SAFC or something like that...

Matt will be tough to get a hold of, he's got his hands full w/ his new project...

You could always try sending him a PM or email

Yeah, the S-AFC and other piggy back devices typically won't work on an 89-92 Probe GT. The air flow meter outputs a signal that is backwards of most meters. I've heard rumors of the GReddy e-Manage working on those cars, but I've never heard of anyone actually installing and making one work. I believe your options(if you want to avoid an FMU) include an ECU chip or installing a standalone fuel computer. InjectTech has been offering a chip and Megasquirt is currently the bandwagon choice of standalone computers for Probes. I've yet to see any 1st-gen GT's running a Megasquirt though.

A LOT of people just go with an FMU and an adjustable FPR.

Are you talking about probe people? what FMU works?

[fallguy]

I replied to your PM.

I used a Holley Rising rate FMU. You could always use a regular fpr to control base fuel pressure and then use the rising rate fmu to tweak the boost fuel needs. I haven't had that setup in a while though. Your right in that your really limited to what you can use with the stock MAF. The probe ecu processor is really slow too.
