CJR Stage 1.1 Flash Tune (REFLASHED) ECU for 2022+ Honda Monkey 125! Stage 1.1 was tuned to aftermarket intake/aftermarket exhaust. The reflash will also improve the response and performance of the Monkey by removing the variety of restrictions on the OEM ECU, which will bring the engine to life!
This is a NEW ECU that has been reflashed, therefore you don't need to send your ECU in and wait for the reflash.
Stage 1.1 is intended for aftermarket intake and exhaust.
Changes include -
-
Revised Fuel & Ignition table to remove the dead spot in the mid-range, improves throttle response, lower engine temps, and increase overall performance across the entire RPM range. CJR fuel and ignition tables are each custom made in-house with a combination of CJR development parts.
-
Raised RPM Limit - CJR raised the RPM limit 500rpm on the stock cylinder head for improved top speed in every gear.
-
Revised Closed-Loop/Autotune System - The stock ECU tables are designed to have a lean 14.7 target AFR from 0-90% throttle position, this means outside of wide-open throttle, the stock ECU runs very lean. With our ECU flash we bring that down to allow richer partial throttle and in turn, makes for better throttle response and more power.
-
Revised Start of Injection - When properly tuned, this setting allows us to safely run additional ignition timing to optimize low-mid range throttle response in conjunction with additional high RPM gains across the board. This setting also plays a role in lower engine temps!
-
Engine Oil Temp Compensation Adjustments - This setting allows us to make changes to allow the ECU to have fail-safes in the event the bike begins to run too hot. Once the bike reaches a certain temperature, we ensure it adds additional fuel to help with cooling.
-
Intake Air Temperature Compensation Adjustments - This setting helps keep the fuel more consistent as the outside air temperature changes.
- Optional On/Off Settings -
- Tip sensor delete - For stunt riders or racers that remove the tip sensor for weight or relocation.
- Cold Start delete - This setting disables the high idle upon cold start.
