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, among other changes from the H2 and H2R.
When we see how other people tune the H2 engines, it's extremely aggressive and more like how you would tune a N/A liter 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 joke 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 theory 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 and repeatable 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.
Stage 2 goes a step further beyond Stage 1 with a higher RPM limiter and more aggressive tuning. As a result we found 15-20WHP! We achieved this by working with Brock Davidson from Brock’s Performance so we could squeeze every last HP we can get from the stock Z H2 engine and its unique configuration. This is a nothing left on the table tune and meant for those who are racing, monitoring the bike constantly, and checking fuel quality. Use Stage 1 for a no compromise option.

BT Moto Stage 2 Flash Details:
Ignition - Optimized to make the most power while still being safe and reliable.
Throttle Derestriction - Giving you the ability to utilize 100% of the throttle is paramount in track situations where you need all the power you can get on demand. The factory file has a "dead spot" on the top end that kills the bikes power curve when it should be making the most. This also means any kind of straight line acceleration also suffers. We remove these factory restrictions to ensure a smooth and predictable throttle, all the way to redline.
Lower Fan-On Temp - Let's face it, this bike rides a little on the hot side. To help not only the riders enjoyment but also keep the engine slightly cooler, we've lowered the fan-on temps.
Increased RPM Limiter - The stock RPM limiter is set to 12,700 RPM. We have been testing 13,650 RPM with zero negative side effects. We set the RPM limiter for 13,650 RPM in all gears. This helps you stay in the powerband longer and reduces the need to shift at the track.
Increased Top Speed Limiter - Removed so you can let the bike run free in any track environment.
Traction Control Switch - This one is really just an annoyance that we took care of after riding the bike. We noticed you couldn't switch the traction control system off while riding the bike. With our tuning you now can.
Quick Shifter – We all know how slow the QS is stock. Our tuning reduces “kill” times to make the quick shifter much faster than stock, and a better overall riding experience.
Race Features – Minor features unlocked for the purpose of track use.
Fuel Cut – Optimized for better limiter feel.
IMMO Off – Immobilizer off.
Mode Based Mapping – High power mode will be a pump gas map and medium power mode will have changed ignition and fuel mapping optimized for racing fuel.
Injector Balancing – More power found through injector balancing and throttle based fixes.
Ram Air – Changes to ram air mapping to maximize power and rideability.
What is a BT Moto Handheld Tuner and what are the benefits of having one?
Thoroughly tested by our own engineers, not just for its function but also durability. We purposefully dropped this thing about 100 times just to make sure if you accidentally dropped it, it would still be a usable device.
So why buy it when you can just send in your ECU for flashing and spend less? Let's see the breakdown:
No Downtime - No need to send in your ECU or remove it from your bike at all. You order the handheld, it get's delivered to you, you flash your bike. You never miss a day of riding and no effort removing the ECU.
Go Back to Stock Anytime - You can flash the original, stock file, back into the bike at any time and for any reason.
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.
PLEASE NOTE:
YOUR BIKE MUST HAVE ONE OF THE FOLLOWING ECU NUMBERS: (21175-1568, 21175-1586, 21175-1587, or 21175-1626). 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 BT MOTO BEFORE PURCHASE. We found the ECU numbers we listed are almost all 2020+ Z H2's. We will be working to add more and will update this page when we do.
Our tuning only applies to ONE MODE. This mode will be the highest power 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.
