    R&D Powershot adjustable fuel tuner/controller

    For sale is a R&D 4tec adjustable fuel tuner/fuel controller with instruction manual. Stated for 215hp 4tec's but should work with any supercharged 4tec. Looking for $200 shipped, obo, retail is for $440. It intercepts the fuel injector signal from the ECU, and increases or decreases pulse width at various RPM's. Perfect for anyone running increased boost wanting to fine tune their setup. Has adjustments for Idle/midrange/WOT Allowing you to fix an overly rich idle, tune for good fuel economy at midrange, and finetune WOT AFR's. Perfect for anyone running larger injectors that has issues with an overly rich idle. Below is a link to it in Jerry's store with more information on it.

    You can decrease fuel below OEM settings? I was thinking you could only add fuel with the PowerShot.

    With the settings on "0" You're running OEM fuel curve as if it wasn't installed, you can't go lower than OEM

    That's a good price! I ran one of these for a few years & it worked like it should.

    I've actually done more research on this since I listed it for sale than the entire time I've owned it . Halfway considering keeping it But as stated above, it compliments an rrfpr as a way to further fine tune your fuel map. It allows you to add fuel relative to RPM, as oppose to a rrfpr that increases fuel relative to boost. Looking for $200 shipped for it, thanks.
