BMW 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.

Here's What You Get With Stage 1:

• Power and torque gains due to unrestricted throttle and removal of limiters
• Lower fan-on temperatures
• Smoothing of part throttle and low RPM rideability to combat bucking and jerking
• Removed top speed limiter
• Stronger idle speed to combat stalling on warm up
• Reshaped torque model for more power at all RPM's, part or full-throttle
• Ignition timing optimised for every fuel
• Conversion to lambda
• Full-throttle limiters
• Engine braking in all modes
• Cold and warm start issues eliminated
• Removal of known flat spots in the RPM range
• Rev-limit adjusted for max power
• Lambda limiters adjusted for maximum power
• Throttle valve adjustments

We spent a ton of time removing the mid-range and bad sluggish throttle response, along with the jerking and bucking throughout the power range. The bike drives like a completely different monster after mapping!

Red = Stock flash with 93 Pump Gas
Blue = Stage 1 flash with 93 Pump Gas

The power gains from Stage 1 aren't just peak. You can see power is gained over the entire RPM range over stock. The extended RPM limiter helps to provide less shifting and a broader top-end powerband. This motorcycle has an exhaust system. If your bike has a stock exhaust, the stock exhaust valve is holding back quite a bit of power. We have seen gains upwards of 10whp over stock with our Stage 1 flash.

**Testing performed with US 93 octane pump gas. Usage of a lower octane will yield smaller power gains. Higher octane larger gains**
