DHM ECU Reflash - 22+ HONDA GROM / MONKEY

Two ways to order: Select to send your ECU in and we will flash it and send it back OR Select to purchase a new core preflashed ECU.

    

The 2022 engine doesn't run as lean in the lower RPM as the previous generation, but still runs lean at higher RPM once an intake and exhaust are added. Honda was also very conservative when mapping the new bike, and has left a bit of power and throttle response on the table. As seen in the dyno graphs, we've been able to pick up quite a bit of mid range power and we've also smoothened out the awkward power hiccups that the stock mapping had. 

• Fuel mapping - we remap the entire fuel table to help your bike run safer while also making more power than the factory mapping. We can maintain factory fuel economy at part throttle while also making sure the bike runs safely and effectively under load. Fuel mapping is essential to keeping engine temps down.
• Ignition timing - we modify all spark angle maps to increase throttle response and power while keeping temps down. This can also help with fuel economy at part throttle, while allowing gains across the board when under load. We've altered the timing to eliminate the factory power dip around the 5,000rpm mark.
• SOI - Injection timing is modified to make sure that fuel is delivered at the most precise moment to increase efficiency and power. 
  
• EOT Tables - We alter engine operating temperature tables to make sure the ECU compensates for high engine temps. This failsafe helps prevent engine damage when extreme temperatures occur.
• Optional - Tip sensor delete and Cold start delete

• Stage 1: For bikes that have an aftermarket intake and exhaust installed
• Stage 2: For bikes that have an intake, exhaust, and aftermarket camshaft installed 
• Stage 3: For bikes that have intake, exhaust, camshaft and our DHM piston installed
