fmu + regulator?
I have a 12:1 fmu right now and im running too rich and I thought I could adjust the fmu but I guess i can't. So would a fuel regulator be the next step?

Re:fmu + regulator?
You're probably better off getting an adjustable fmu. I believe Cartech makes them for a fairly decent price. I'm not sure on all this though cause i'm not boosted yet. :-[

Re:fmu + regulator?
use a valve to bleed off/limit the boost the fmu sees to lean it out some
|
Re:fmu + regulator?
Would a bleeder valve screw up other things T'd into that vacum line like the boost gauge?
|
Re:fmu + regulator?
Sounds like it works just like a manual boost controller, except it's inline with the fmu? Which makes sense, because if the fmu doesn't see boost then it won't raise fuel pressure, which will in turn lean out of the mixture.
Don't take my word for it, i'm just a newbie. :) Stan |
Re:fmu + regulator?
I was looking at the recalibration kits for the vortech fmu and it looks like the 12:1 is the only one without a ring type deal around the washer. Dose anyone know what that is, because i was going to try putting in a smaller diameter washer which is all the difference is, but i dont know what that ring is for?

Re:fmu + regulator?
no clue about the ring, but you dont need to hook up the fmu to vacuum, just boost, so a bleeder shouldnt affect anything
|
Re:fmu + regulator?
ok i figured out the ring thing. But the bleeder valve, do you think I could just pick that up at a hardware store? where would i get somthing like that?
|
Re:fmu + regulator?
any kind of valve would work in theory...mind you ive never tried this, although ive seen it done and i will be doing it soon with my new setup
|
Re:fmu + regulator?
uh, you guys still didnt answer his question! he asked if he could use the fpr with the fmu to help lean the fuel out..you can just use that! use the fmu and with the fpr adjust the little bit of extra or less fuel you need. ofcourse he can use an adjustable one but its better to work with what you got or what is less expensive...
|
Re:fmu + regulator?
i already answered his question, and since he doesnt have the fpr, that would be more money he needs to spend...even with the fpr, the fmu is still rising at too high a rate and theres not much you can do with the fpr other than change the base psi i think

Re:fmu + regulator?
