Harley-Davidson ECU Remap Tuning

We The Remap Link offer ECU tuning services for Harley Davison in-house or through the mail. We're experts in Harley Davison tuning and have tuned numerous Harley Davison in our workshop located in Birmingham, West Midlands. We offer services for a wide range of Harley Davison models, including race remaps and custom remaps. We can increase the power output of your bike.

Harley Davison's remapping and ECU tuning process begin by running the standard bike on a dyno and measuring its power output. They also use standalone diagnostic equipment to monitor various engine function parameters, such as air-fuel ratio, throttle plate opening, spark timing, injector duty cycle, lambda readings, engine knock, etc. at different accelerator twists grip positions. This whole process is repeated for every mode that the bike has.

Our development bikes are put through their paces in the real world so that we can assess how they perform. This allows us to make any necessary changes and improvements. We also consult with other riders and existing customers to get feedback and find out about any common problems. Creating a good remap is about more than just making the bike powerful. We want to provide a Harley Davison that rides well, with a linear, progressive, and smooth power delivery, and responsive throttle.

It has come to our attention that many Harley Davison motorcycles are equipped with aftermarket exhaust systems but still have the original ECU. This is hardly surprising, as the ECU can cost over £900. However, when fitting a new exhaust system, it is necessary to adjust the fuel map to suit the new system. This is to prevent damage to the motor from lean running and to ensure that the bike performs correctly.

Harley Davison, there couldn’t be a motorcycle manufacturer more synonymous with 2 wheeled transportations! William S Harley and Arthur Davidson presented their first motorcycle in 1903, a racing machine built in a 10 X 15 foot wooden hut in Milwaukee. Passion flows deeply in Harley owners as it does at BHP UK. When we remap a Harley Davidson, our aim is to make more power and torque but also to improve the throttle response and make the ride more pleasurable.

All our remaps are developed on our rolling road before we road test the bike to make sure it works in the real world not just on our dyno. The BHP UK ethos is to buy our own vehicles to develop, so we do our learning on our own machines, not your pride and joy.

Harley Davidson owners love to modify their bikes and as we write all our maps in house, we can custom tune them for any modifications.

We can remap your Harley through its on board diagnostic port and will remap the factory ECU meaning we can adjust any engine parameter that we need to. These parameters include fuelling, spark advance, throttle response curves, torque limiters, lambda requests and closed loop monitoring.

We can retune these to suit the exhaust like normal but without all the restrictions in place we can also tune beyond what is enforced by the race kit map meaning we are only limited by ourselves. How far? Well when considering engine internals making sure they can cope with what's happening in there, how much fuel and how much spark you're using, it really comes down to a case of how agile your tuner's mind is and what school he or she went to!

The ECU programmer gains access via the OBD2 hole under your seat, so there are no holes drilled into the frame nor any tacky stickers on your bike. And because it plugs directly onto the OBD diagnosis port you aren't even electrical wiring modifications needed and this simply becomes "plug 'n' play"

There is nothing else like our Harley Davison Performance ECU Re-flashing service out there!
