    URD AFR calibrator.

    Used for part throttle closed loop fuel enrichment on 2000+ boosted Tacoma or 4runner 3.4 engine (and others). I can't find the Split Second software cd, but you can buy or download from them for 40 bucks.20180912_183830.jpg

    These go for 250 new, plus shipping.

    SOLD

    Just curious as I'm trying to figure out all this fuel modification stuff with the supercharger still...what kind of condition(s) calls for this particular mod? I have the URD 7th injector kit installed but is this calibrator necessary for better fuel management in general, or is it only needed if you're still having issues running lean?

    This would be for finer tuning of part throttle/closed loop under boost. The ecu fights very hard to trim fuel in closed loop to achieve 14.7 Air/fuel. Lean fuel and boost is no good. @eon_blue

    Thanks for the info. I was running really lean until I got the 7th injector about a year ago, but I still think I tend to run too lean under partial WOT so this might be something I need. Unfortunately I can't swing it at the moment but if it's still for sale in a few weeks or so I'll be hitting you up.
