    how do you know when/if you need a CMD or fuel controller?

    My afr's seem to be kinda all over the place in some places. so it got me wondering if I need some sort of fuel controller and if so what are my options?

    You can't go wrong with a CMD - autotune set up. Best part is you'll never have to worry about looking at your a/f gauge again!

    what about the Rude fuel controllers? they any good.

    If I got the cmd, i would be manually tuning it as I don't want to have to purchase their wideband when my mtx-l does a good job.

    Rude no longer makes fuel controller. Best solution is Dynojet CMD

    yeah I heard they don't make the Rude's anymore. I just saw a used one for sale in the classifieds and was wondering if they where any good. I did a search but didn't find a whole lot about them.

    Dynojet CMD with the wideband and autotune is the shitz! Get the LCD display and set it and forget it. No more fumbleing with fuel pressures, although some guys still like to tune as they ride I prefer the tuner. A little pricy bit IMO worth the money.

    When you get to the point where you cant get the AFR where you need it to be top and bottom then that's when you need a way to control fuel with, CMD, VTech, MoTec.

    A RRFPR can only do so much.

    Thank you hotbird. That answers my original question. Guess that means I should start looking into getting one as I'm good up top(11.8-12) but weird before boost. 14'[email protected], low 12'[email protected] 2k, then up to mid-high 14's around 5k, then low 13's after 6k and falling.
