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.

If your modifications are not in the drop-down, please add in notes or email us with you ordering number! Please list all modifications injector, cam, exhaust, throttle body, etc, even if purchasing parts from us at the same time 🤘🏼
