ECU flashing is not only MORE COST EFFECTIVE than any other tuning solution, it is far SUPERIOR to any other tuning solution because it also allows for more precise tuning of fuel and ignition timing maps which automatically compensate for changing atmospheric conditions. It also allows for the modification of parameters that are not otherwise adjustable through other tuning solutions, such as electronic throttle mapping.

Our Mail-In ECU Flashing Service also comes with FREE future mapping updates for as long as you own the motorcycle. The only cost you are responsible for is the shipping of your ECU.

For any/all questions regarding ECU flashing, please email us at support@2wheeldynoworks.com

This Performance Package combines the unrivaled performance of the Graves EVR Slip-On Exhaust system, the precision fuel control of the FTECU Active Tune system and our custom 2 Wheel DynoWorks ECU flash and Block Off Plates! The full retail value of everything included in this Performance Package is $2,499.99 plus shipping, but when we bundle this Performance Package together you save $300 and shipping is FREE.

Included in this Performance Package:

Graves EVR Slip-On Exhaust Yamaha R1/R1M/R1S

The Graves EVR Exhaust offers the peak power of a full system without sacrificing any low-end usable power. This was possible thanks to the Grave's Exhaust Valve Race Technology. Already incorporated into the factory Yamaha bikes, EVR features an ECU controlled butterfly valve that provides great power output and drivability while maintaining the great looks of a shorty muffler. Additionally, the sound output is tamed at low RPMs but is unrestricted when the throttle is wide open. This would not be possible with a sound insert as it would rob power from the entire RPM range.

Graves Slip-On Exhausts are designed for the rider seeking top of the line performance, fit, finish and value. Developed using the same technology that has powered the Monster Energy Graves teams to consecutive AMA Superbike championships, the Graves Everlast packing produces an exhaust note like no other and holds up longer to the extreme conditions of a high-revving motorcycle. Graves incorporates advanced welding processes to reduce oversized welds that can cause excessive heat buildup. A special pipe bending technique known as mandrel bending is used for all Graves exhausts to prevent wrinkles and ovalization of the exhaust pipes. All of this combined not only streamlines the appearance of the exhaust systems but saves more than 10 pounds compared to the stock exhaust!

FTECU ActiveTune

This Kit lets your FTECU equipped bike fine tune the fuel mapping as you ride!

Once installed and activated, the ActiveTune kit monitors the fuel mixture making fast and consistent changes to mitigate changing fuel requirements.

Our breakthrough system replaces your inadequate stock O2 sensor with a proprietary FTECU lambda controller and the latest generation Bosch LSU 4.9 sensor.

Note: Stock is compatible with a stock wire loom, YEC is compatible with a YEC (Race) wire loom

This kit includes:
– 1 FTECU YAM-01 Lambda Controller
– 1 Bosch LSU4.9 wideband O2 sensor (M18 x 1.5 thread)
– 1 Product Activation Card

2WDW Block Off Plates

Air induction systems (AIS) reduce hydrocarbon emissions. Block off plates seal the inlet ports used by air induction systems. Removing the AIS system will save weight, reduce engine clutter and give us accurate air:fuel ratios which are needed when tuning your bike.


2WDW Custom ECU Flash

ECU flashing is not only more cost effective than other tuning alternatives, but it is far superior because it also allows for more precise tuning of fuel maps which automatically compensate for changing atmospheric conditions. It allows for modification of parameters that are not otherwise tunable, such a throttle valve actuation. 

Our mail in ECU flash service also comes with unlimited ECU re-flash services as long as you own your motorcycle. All future re-flash services are free of charge. The only cost you are responsible for is return shipping of your ECU.

Custom Flashing Service:

– Disable Injector Decel Cut
– Professional fuel map modification to suit aftermarket exhaust
– Removal of all gear based or speed dependent restrictions, TRE
– Optimized timing maps for 91+ octane
