That isn't quite correct. Both Kev's and the Dynojet O2 devices work in exactly the same way. They both allow the closed loop to operate as it would do normally, but control/optimise the signal sent to the ECU to obtain a fixed A/F ratio. Kev's O2 Controller is definitely tuned to give 13.6:1, I'd guess the Dynojet version is the same? (Kev might be able to answer that one?) Are you sure you are not getting mixed up with Kev's fuel mod, which is adjustable and works only in the open loop?

You will find that most maps that are available to download will be built around about the 13.6:1 mark. You can go as far as 13.2:1 for maximum power on a bike with a hot cam, big bore etc. This is the main reason you would perhaps want to stick the bike on a dyno, so you can match the A/F ratio exactly to your needs and mods.

It doesn't matter, if you've got a 2007 or later XTX/R with an O2 sensor, then the principle of controlling A/F ratio is the same - it applies to all XT660s.
