Harley-Davidson & Indian Dyno Tuning, ECU Flash & Service
Big twins get the same rollers, the same data and the same printed sheet as the superbikes.
A Harley dyno tune or Indian dyno tune starts the same way every session here does: a baseline pull, air-fuel logged across the rev range, then fuel and timing tables corrected for the exhaust, intake and cams actually on the bike. Factory calibrations run lean and hot to pass emissions; a proper tune fixes the heat, the surging and the flat spot off idle before it chases peak numbers.
ECU flashing for Harley-Davidson and Indian covers the fuel and ignition tables, rev limiter, deceleration fuel cut and the drivability features the platform supports. Pair it with a stage upgrade (full exhaust, high-flow air filter, cams) and the dyno session happens once.
Service follows the factory schedule: oil change, primary and transmission fluids, valve adjustment where applicable, coolant flush on liquid-cooled models, tire change, chain or belt and brakes.
