Kawasaki Handheld Tuner with Custom Mapping

No need to send in your ECU or remove it from your bike at all. You order the handheld, it gets delivered to you, you flash your bike. You never miss a day of riding and no effort removing the ECU.

The 2020+ Kawasaki Z H2 is an interesting bike. It shares a lot of similarities with it’s supercharged brother, the H2. It also has quite a few differences from the H2. Put simply, the Z H2 is the biggest departure from the H2 family we’ve seen yet. In the engine alone the Z H2 has more compression, a different cylinder head configuration, less boost, and more than the H2 and H2R models.

When we see how other people tune the H2 engines, it’s extremely aggressive and more like how you would tune a N/A litre bike. From a lot of data logging and testing we have found the limits of the motor to be quite different from its H2 counterpart. It’s safe to say the issue that H2 motors aren’t reliable isn’t due to the engine itself, but rather how it’s tuned. With the differences in the engine between the H2 and the Z H2, using the same tuning between the two can result in catastrophic engine failure.

Many H2 engine failures can be attributed to too much ignition timing and too much RPM in tuning. While the numbers will be lower than its H2 counterpart, the Z H2 with our tuning will be reliable and consistent. When you think about it, the Z H2 is a non-intercooled engine and must be tuned more delicately to ensure a reliable result. Of course, customers with modifications such as an intercoolers or headwork can accommodate different tuning. Ultimately we are here to utilize this amazing engine but will not sacrifice reliability for an extra 10-20whp. Reliable performance solutions is what we do and we spend many hours with a lot of data logging equipment to ensure that outcome.

WHAT’S INCLUDED WITH OUR STAGE 1 Z H2 FLASH:

• Fuelling Adjusted (per gear)
• Ignition Adjusted (per gear)
• Throttle Derestricted (per gear)
• Lower Fan-On Temp
• Increased RPM Limiter
• Removed Top Speed Limiter
• Traction Control Switch On-The-Fly
• Exhaust Valve Management

PLEASE NOTE

YOUR BIKE MUST HAVE THIS ECU NUMBER: (21175-1568, 21175-1586, 21175-1587, 21175-1626, 21175-1604). To find this number either look at the back of the ECU (in nose of bike), or call your local Kawasaki dealer and ask them what your ECU part number is based on your VIN number. The numbers we listed apply to all US bikes and a Euro version. If your bike has a different ECU number EMAIL US BEFORE PURCHASE. Your ECU number can be found on the ECU itself in the tail of the bike. We found the ECU number we listed is almost all 2020+ Z H2’s. We will be working to add more and will update this page when we do.

Due to the sensitive nature of the Z H2’s AFR (air/fuel ratio) and the platforms almost endless aftermarket options, the file we deliver you may need the fueling to be adjusted to meet your bikes individual needs. In this instance we recommend a piggyback fuel controller and dyno time, or an “auto-tuner” that can aid you in correcting your fuel maps (if needed).

Our tuning only applies to ONE MODE. This mode will be the highest power mode: sport mode. Please note that all other modes will run like stock and will not be derestricted. We have done this at the request of the community in general.

IMPORTANT!

It is crucial you check your oil level carefully after each oil change. If you add too much oil (above factory recommended ‘high’) “windage” may occur. This is when the crankshaft, rotating at a high RPM will churn the oil to the point where small air particles are trapped in the oil. This is bad for many reasons. The main reason this is bad for the Z H2 is because the crankcase is under pressure and has a very high tendency to push this aerated oil to the airbox and supercharger. If the oil gets to the supercharger, it will start to feed the oil to the combustion chamber to burn. If this happens the octane rating of the fuel, now mixed with oil, lowers significantly and causes massive detonation. EXTREMELY IMPORTANT TO MAKE SURE YOUR OIL IS AT A PROPER LEVEL BEFORE RIDING.

Dyno Proven

Yes, you’re reading that right. At peak RPM you’re gaining OVER 100whp FROM JUST A FLASH! The gains can be seen and felt across the entire RPM range. Even down low where you think the power is similar, the bike takes off better and feels more lively. Up top is were we really see our tuning shine! After we remove the factory throttle limits we are left with a lot more power to play with and tune. Increasing peak RPM safely also helps ensure a larger powerband, while still reliable and consistent.

This Z H2 came in with a exhaust and filter. All testing done with same mods and all testing performed on 93 pump gas, same day.

RED – Factory Tuning: 180whp / 95wtq
BLUE – BT Moto Flash: 227whp / 101wtq
GREEN – BT Moto Flash with VP Race Fuel: 239whp / 106wtq

Q & A's

What does a BT Moto handheld tuner do?

The BT Moto handheld tuner stores multiple maps that you can change at any time. Unlike the mail-in ECU option, this means no downtime for your motorcycle while we do the flashing process. You can also go back to your stock mapping at any time you'd like and even read and clear engine faults. Additionally, some models will allow for DTC reading / clearing and maintenance light resets.

How does the BT Moto handheld tuning process work?
Easy, you purchase the handheld, we ship it to you. Use the BT Moto handheld tuner to copy your motorcycles stock file (motorcycle will still run fine after this) then email that to Motobull. BT Moto will then create a file from your stock mapping and we will email it back to you so can upload it to the handheld. Once uploaded you'll be able to flash your motorcycle with the BT Moto handheld tuner.

How do I put my motorcycle back to stock with the BT Moto handheld?
Go to "Work" -> "Writing" -> "Original" in the handheld and then it'll load the original factory stock file to your motorcycle.
