Grom ECU FLASH

This is a basic tune option for budget friendly performance. It includes a custom tune specific to your build. These tunes would fall in line with the average ECU flash needed for day to day use.
- Revised Fuel Map
- Revised Ignition Map
- Custom RPM Limit with "Race Limiter" (Faster/Smoother RPM Limit)
- This flash retains the stock learning trims for idle/partial throttle, with open loop (no autotune) wide open throttle
- Revised Closed Loop areas -
-- Flashed ECU Target 0-60% TPS = 14.7 AFR for optimal fuel economy
-- Flashed ECU Target 60-100% TPS = 12.8-13.2 AFR for optimal performance
-- OEM ECU 2014-2015 OG Grom AND 2017 SF Grom = 0-64% Closed Loop
-- OEM ECU 2018-2020 Grom & 2019+ Monkey = 0-90% Closed Loop
-- We revise the autotune areas from the factory 0-90% down to 0-60% throttle for all models, this dis-allows the closed loop to have an affect on the open loop portion of the map which causes the bike to lean out after learning miles for wide open throttle.
- Optional Fast Idle Valve Delete - (For those that may not like the loud cold start in a quiet neighborhood, you can also unplug your gray sensor on the throttle body)
- Optional Tip Sensor Delete (A lot of racers will delete the tip sensor to save weight along with some stunt riders relocating their sensor for a subcage)
- Optional Learning System Disable (A fixed open loop map, for intake/exhaust bikes only. Great for stunt riders that would like to be able to raise their idle without having the it creep up while riding!)
- Optional Decel Fuel-Cut (Less engine braking, smoother on/off throttle)
- Optional Side Stand Delete (Often used for racers when deleting kick stand
- Disable EVAP Canister Check Engine Light (For removal of the emissions canister)
- Revised Tip in Fuel Tables
- Revised Tip in Ignition Tables
- Revised Injector Timing
- Revised Oil + Air Temperature Settings
- Includes 1 yr warranty

During checkout, specify your mods so the proper flash can be applied to your sale. A Hindle exhaust vs a Yoshimura exhaust for example have drastically different fuel tables. So it is important we set you up on the tune that fits your build the best.
