SAFC won't correct

nametakennow · 11-22-2005, 02:11 PM

Yes, I've searched. If I missed something, link me.

Anyway, my car's still in the shop, it's running crazy rich and the guys are still poking around to figure out why. For whatever reason, changing the maps on the SAFCII doesn't do anything.

Info:
B15 SE w/pp 5spd
Avenir T25 turbo and mani
JohnnyRaceCar FMIC
custom plumbed
---
more importantly
MSD 34lb/hr injectors (I think these are within 50% size difference, shouldn't the SAFC be fine?)
SAFCII

I've recently come to the realization that simply plopping a filter onto the VC breather has caused me to have what essentially amounts to a big vac leak. However this lends itself to a lean condition, rather than rich, so I guess it's not a factor...

SAFC wiring has been checked and rechecked, I had it on the car for a couple weeks before even starting the turbo project and it read everything fine... the injectors are peak and hold low impeadance.

Thanks, as always.

What MAF are you using?

You should be fine with the SAFC im currently using a safc for my ve, using the ve injector with the stock ecu.......Are you running a wideband???? otherwise get it dyno tuned with a wideband....
yea make sure your not running a bored maf that makes the motor run rich also.....unless you gotta jwt

Stock MAF.

The shop it's at will be using a wideband to tune it. They've tried +50 and - 50% and there's been little or no change in a/f ratio.

However, it appears that I may have had wrong information on my fuel injectors (they're low imped, apparently I may have needed high?) to begin with, I'm trying to get confirmation right now.

edit: B15'ers got me covered - resistors in the wires to the injectors will do the trick

Get that vacuum leak situated. Lean is not better than rich any way shape or form.

Yeah you need high impedence injectors
