Tier1Tuners Parts & Accessories

Tier1Tuners come out of the Dobeck tuning lineage and build fuel management kits aimed at riders who don't want to pay for a custom dyno map every time they change something. The +CCT Acceleration Optimiser samples injector data on every crank revolution in performance mode and adjusts fuel delivery on the fly to suit the current intake and exhaust setup.

Coverage runs across Sportster XL883 and XL1200, Touring platforms, and current 107ci Touring and Softail bikes. Useful when the bike has bolt-ons but doesn't warrant a full ECU replacement.
