Honda 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 20-23 Honda CBR1000RR-R SP is probably one of the most sought after and interesting superbikes we have tested this year. Every aspect of this bike is AMAZING! It’s the updated, all new spec flagship Honda sport bike, based off the RC231V. This bike comes with a slew of MotoGP technology! At BT Moto, we focus on niche bikes that require our help for race use and change from from great to spectacular.

While the Honda is a new platform to add to our already robust line-up of programming, the Kehlin ECU is not. With the help of our engineers, we have been able to streamline the much needed ECU development in a short amount of time. This has quickly turned into the best upgrade you can get for your RR-R with gains of up to +30HP! We have found the refreshed 20-21 CBR has a lot of positive changes, not only visually but also on the software and engine side. We use factory information and reverse engineering, meaning we don’t use incomplete editors to nudge fuelling a little, like our competitors do. We had to develop ECU strategies from square one. From acquisition of the bike, to spare control units to Euro and US testing, we find out how everything works down to the last detail and what differs so much in power output. After all our hard work we are able to bring you our Stage 1 and Stage 2 ECU upgrades.

Note
At the moment we have mappings for: Full header + stock exhaust, Akrapovic (Other mapping is possible based on our best guesses but recommend AFR confirmation post flashing via wideband gauge)

UK customers - Map install and full Dyno testing facilities available.

WHAT STAGE 1 INCLUDES:

• Correct fuelling on both banks in “Alpha N” mode and race modes
• Raised RPM limiter to 15,500 RPM (beyond US/Euro restricted limitations)
• Top speed limiter removed for better use of 5th-6th gear
• Raised load limiters
• Revised throttle limitations to 100%, stock bike restricted to 66% throttle at redline, less than 50% for US
• Ignition timing adjustments
• Corrected fuelling that was causing engine break-up and aggressive hesitation
• Exhaust valve adjustments
• Oxygen sensor feedback for full exhaust systems
• Up to +30HP/+30TQ gains

WHY THIS IS THE BEST UPGRADE YOU CAN BUY

Currently there are no options to tune the new CBR, so with the assistance of our good buddy 650ib, we used our experience in other markets and platforms come up with our own. Using our in-house motorcycle dynometer and datalogging capabilities, we were able to systematically fix the glaring deficiencies in the platform. Turning it from one of the worst performing Superbikes available to one of the most potent. We all know the CBR1000RR-R SP is a great Superbike, unfortunately we also know it isn’t perfect in its stock form. These are the issues we have seen ourselves and fixed.

Through research we have found other customers have also verified the following issues:

• No tuning options currently on the market
• Low power (160WHP~)
• 182MPH top speed, no use of high rpm in 5th and 6th gear, even in Euro bikes
• Startup issues when exhaust is installed or even stock
• Issues when exhaust is installed, fault codes, lean misfire, exhaust break up
• Acceleration that isn’t smooth through the entire RPM range due to inaccurate AFR
• Engine seems to struggle off idle to 4000rpm and then lurch at 10,000 RPM
• Power that seems to level off (flatten) after 10,000 RPM with the throttle limiting in place

PLEASE NOTE:
Due to regulation compliance we will not turn off any off-road racing errors that may occur due to changing or deleting parts from the motorcycle

However, if you have fitted an aftermarket exhaust system which included a small plate to bolt onto the top of the exhaust servo to restrict the servo’s movement (so the bike’s ECU still thinks the exhaust valve is connected and working correctly) we strongly recommend fitting an Exhaust Servo Eliminator Kit instead (see Options). We know of customers who experienced FI light issues utilizing the servo plate method.

We also recommend fitting a PAIR Valve Eliminator Kit when fitting an aftermarket exhaust system (see Options).

RED = 135whp / 71wtq (pump gas with exhaust system)
BLUE = 147whp / 77wtq (pump gas with exhaust system and BTM Stage 1)

The graphs below represents a 2021 HONDA CBR1000RR-R SP with an aftermarket exhaust and air filter. You can see the power get extremely “jerky” in the low and mid-range RPM. If you look at the below power graph you can clearly see the issue. Without proper tuning the AFR (air/fuel ratio) spikes to 16:0:1 (with AIS clamped). Something this lean (lack of proper fueling) is actually harmful to your motorcycle and may damage engine components after extended use. The Honda in particular is EXTREMELY sensitive to fuel changes, up or down and drastically reduces or adds power based off its fuel mixture.

Test bike: 2021 Honda CBR1000RR-R SP
Owner: 650ib
Modifications: P08 Filter/Akrapovic header

Graph 1 (Stock Tuning):
Below is the stock dyno chart for US and EURO. The bike runs a 16:0:1 to 15:0:1 AFR (air/fuel ratio) mixture with these Akrapovic header modifications on the factory map and knocks / pings as a result in the bottom end of the RPM range. Increasingly more runs and heat will make the bottom even worse as it lost more power every run and struggled to pass 6,000RPM without an audible misfire. This is the best cold run we could produce on our in-house Dynojet. Peak numbers mean very little here because of the large bottom end losses.

US STOCK: 167whp / 75wtq
EURO STOCK: 188whp / 80wtq

Graph 2 (US vs Stage 1 Tuning):
Below is the US stock dyno chart vs our tune file for pump gas. The bikes mixtures were corrected to make power and peak performance, throttle was de-restricted, timing was optimized, and the rev limiter was slightly raised. This bike is 4 mode tuned Alpha-N from idle to redline at all throttle positions. Most importantly the top speed limiter of 182MPH (which includes all Euro bikes as well) was removed so the bike can make use of 5th and 6th gear where it normally topped out at the top of 4th. The engine no longer struggles and makes consistent power, over and over at this level.

US STOCK: 167whp / 75wtq
BT MOTO STAGE 1: 196whp / 82wtq

Graph 3 (EURO vs Stage 1 Tuning):
Below is the EURO stock dyno chart vs our Stage 1 tuning. The EURO bike still runs a 16:0:1 to 15:0:1 AFR mixture with the Akrapovic header modifications on the factory map and knocks / pings as a result in the bottom end of the graph. Increasingly more runs and heat will make the bottom even worse and it lost more power every run, struggling to pass 6,000RPM without an audible misfire. There are a bunch of changes in the European model, but what most people are interested is the European throttle is 100% open past 9,500. The European models have an even lower speed limiter than the US bikes! Now don’t be fooled, this has its own set of issues so this is barely an upgrade for the US bikes. We will offer an EU file with our changes as well, most importantly the top speed portion and fuelling.

EURO STOCK: 188whp / 80wtq
BT MOTO STAGE 1: 196whp / 82wtq

Graph 4 (VP MR12 Testing):
Below is the stock dyno chart vs. our tune file for pump gas vs. our tune file for VP MR12. The bikes mixtures were corrected to power making levels for MR12, nothing else was changed for now and these were the natural gains showing the bike is octane rated.

BT MOTO STAGE 1 WITH VP MR12: 206whp / 87wtq
BT MOTO STAGE 1: 196whp / 82wtq
US Stock Tuning: 167whp / 75wtq

Graph 5 (Stage 1 With And Without Aftermarket Velocity Stacks):
Below is our Stage 1 flash with a full exhaust system with and without aftermarket velocity stacks. You can see little to no loss in the mid and low-range RPM. Up top you can see a significant gain.

BT MOTO STAGE 1 With Exhaust: 192whp / 81wtq
BT MOTO STAGE 1: With Exhaust and Velocity Stacks: 201whp / 82wtq

RED - Stock bike + Akra racing system – 207 whp / 83.6 wtq
BLUE - BT Moto Stage 1 + Akra racing system and Sprint Performance Air filter – 214 whp / 82.8wtq

Note:
All in-house testing performed with 93 octane pump gas, unless otherwise stipulated. Different modifications and dynometers may make different power. Usage of a lower octane will yield smaller power gains. All power is measured from the wheel and not the crankshaft, whp (wheel horsepower) and wtq (wheel torque).

STAGE 1 PURCHASE REQUIRED FOR STAGE 2

Stage 2 was developed ONLY TO WORK WITH BRENTUNING MOTO VELOCITY STACKS. You need to purchase and install these stacks along with Stage 2.

WHAT STAGE 2 INCLUDES:

• Correct fuelling on both banks in “Alpha N” mode and race modes FOR BT MOTO VELOCITY STACKS.
• Fan Temp lowered for optimized cooling (BT MOTO ONLY FEATURE)
• Decel fuelling and engine braking changed for smoother throttle on/off transitions (BT MOTO ONLY FEATURE)
• IMMO off (keyless option) (BT MOTO ONLY FEATURE)
• Sprocket, tyre size, and traction control changes customized for each file (based on customer request) (BT MOTO ONLY FEATURE)
• Injector phasing changes for maximum power and optimal rideability (BT MOTO ONLY FEATURE)
• Up to +12HP mid-range power increase over Stage 1
• “Race features” available upon request (BT MOTO ONLY FEATURE)
• STAGE 2 INCLUDES ALL FEATURES FROM STAGE 1

By installing BrenTuning velocity stacks and Stage 2 tune a massive mid-range power and torque increase can be gained over the Stage 1 tune

Note, we believe the Stage 2 power gain would have been more phenomenal had the test bike been fitted with the Akra full racing system instead of decat stock headers and Akra track day db link pipe.

RED - BT Moto Stage 1 + Akra racing system and Sprint Performance Air filter – Mid range: 178.5 whp / 83.3 wtq
BLUE - BT Moto Stage 2 + Velocity Stacks, decat headers + db link pipe and Sprint Air filter – Mid range: 190 whp / 88.4 wtq

What is a 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.
• STORE MULTIPLE MAPS – When you send in your ECU, you only get one map. You might be thinking, “why would I need more than one map?”. Storing multiple maps means you’re able to flash for different fuels. If you’re a serious track competitor, we can work with you to get you different mapping for different tracks. If, for example, you add an exhaust to your stock bike, we can email you a file that takes the new exhaust into account with the changes you need to optimize your bike’s new modifications.
• GO BACK TO STOCK ANYTIME – Not only can you store multiple race maps, you can also flash the original, stock file back into the bike at any time and for any reason.

Q & A's

Can the BT Moto handheld be used for diagnostic checks?
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.
