Harley-Davidson & Indian ECU Flash and Tuner Modules

Flash the factory ECU or fit a tuner module. Either way the calibration is written for your parts and proven on the rollers.

A Harley ECU flash or Indian ECU flash rewrites the fuel, ignition and limiter tables inside the stock module. It keeps the wiring factory and the bike clean, and it is the usual answer for a Stage 1 or Stage 2 bike that will stay close to stock. Tuner modules such as Dynojet Power Vision, Vance & Hines FP4, the Screamin' Eagle Pro Street Tuner and ThunderMax add a device, which some riders prefer for the on-bike data, the map switching and the option to return the bike to stock before a dealer visit.

We fit and license the module, load a starting calibration built for the exhaust, intake and cams on the bike, then finish it on the dyno. A base map off the internet is a starting point at best; the air-fuel log is what proves the bike is right across the range.

Indian Thunderstroke, PowerPlus and Scout platforms are covered with the tuners the platform supports, and the same dyno session verifies the result.

Questions

ECU Flash & Tuner Modules FAQ

Flash or tuner module, which should I pick?

A flash keeps the bike factory-clean and is the lighter option for Stage 1 and 2. A module gives you on-bike data, map switching and a quick return to stock. The model year decides which ones are even possible; we will lay out the options for your bike.

I already bought a Power Vision. Can you tune it?

Yes. Bring the module, the cable and the bike, and the session finishes the calibration on the dyno.
