If you own a Triumph (also some Aprilia, KTM) You may be interested in this freeware. I'm a big fan of DIY and this software looks very useful. All you need is a OBD2 USB cable (VAG KKL Cable for 409.1 Audi VW Skoda) about $20 on Ebay. More details on TuneECU site... The cable I'm planning to try it out shortly. There is an updated tune available for my Tiger and I should receive my cable soon.
