One of the key features is reusing pins for multiple inputs or outputs. For example, if your motorcycle model does not have a Chassis fan, you can reuse that pin to drive something else, like a Methanol injector. We also went for as easy to use canned tunes. In theory all you need to do is enter your vin number, select which options you’d like on, and you’re good to go! Alternatively if you contact us and send us the information, we’d be glad to pre-program the ECU here and send it off to you plug and play ready!
