Sotck FPR and z32 MAF

[Miata Master]

I know that with a Walbro 255 and stock maf, and stock FPR.

It runs RICH.

And a completely stock fuel setup with a z32 MAF runs LEAN

Would a walboro pump match with a Stock FPR (RICH) with a z32 Maf (LEAN)

RICH + LEAN = STOICH?

In theory, it may work.

However, considering how much a FPR costs these days, especially a direct bolt-on NISMO FPR for $104 shipped, I would just go with that that.

There is no use risking messing with the very important air/fuel ratios based on a rich/lean word and cancelling each other out to make stoich.

Also ur gonna need something to tune the car to make use of the z32 maf

how does your car run with stock fpr and z32 maf with no piggy back or PFC.

Ok like they said you can't really say it is Rich cuz who's to know whether thats a good thing or bad. Best advice would be to get a FPR and also a Wideband so you can get a accurate reading. Will pay off big time.
