2018-2021 H2 SX /2020-2023 ZH2 Flash (SE & +)
I have flashes available for all exhausts made for the h2sx or zh2
I can also add the woolich race tools for another $500, this adds quick shifting, autoblipper, and launch control to the base model, contact me if you would like to add this
I also have a flash if your running an intercooler ( 250 hp run above, with Brocks full system )
and an E85 tune if you are running a zx10 header exhaust
contact me for details on the intercooler and E85 flash
Remove your ecu , send it to me, reinstall your ecu and enjoy
The flash is much more then just full throttle power but the full throttle gains are huge without the tune pushing the edge of safety. Max power gains are in the neighborhood of 40 hp but there are areas in the curve that is even more extreme.
After the flash ALL MODES MAKE PEAK POWER AT FULL THROTTLE.
This is important to understand. No pressure to use full power mode if you find the delivery intimidating. Switch to medium or even low power mode and you will get the same insane pull at full throttle.
I have spent a lot of time and miles getting the fuel mapping dialed in for all throttle positions to achieve the goal of what I wanted for each mode.
Low power mode is a touring mode. It is set up to maximize fuel economy and will get the same or better fuel mileage then the stock bike if ridden the same. The bike still has a nice responsive throttle and makes great power through out.
Medium power mode is what i would call a sport riding mode. It is set up to have a smooth transition from closed to open throttle and to have a linear power delivery. This is so that when cornering aggressive you get the response you want from the throttle.
Full power is maximum response mode. It is set up for maximum response at all throttle positions. It makes crazy speed and acceleration with minimal twist of the throttle.
other features include turning the cooling fans on earlier to keep it cooler in traffic
the ability to adjust power mode and traction control level while moving, the throttle just has to be closed ( Not SE+)
As with all my flashes lifetime reflashes to the purchaser as long as they own the motorcycle as updates become available or as you modify the bike are free just pay my return shipping

If the dealer does a reflash of the ecu after having my flash, it will write over the key that is in the ECU. The key is what allows me to flash the ecu again without having to buy another key. This is how reflashes are able to be free. If the dealer reflashes your ecu and you send the ecu back for a reflash to me there will be an $80 charge to restore the license.
All of my h2sx flashes now include the recall changes made by Kawasaki
