Powercommander V Autotune switch behaviour

This video shows how the Autotune switch works - if you install one of course! - on a Powercommander V. It proves that when you turn the Autotune off, it not only stops actively listening to the Air/Fuel ratio and applying adjustments, but it also ignores what is already in your trim table.

how do you display the engine temperature on screen ...... and is it possible to do so using powercommander 3 usb ??

[KaldekBoch]

@alykarate Engine temperature is a built in feature of the Power Commander V - you only need to tap into the engine coolant sensor wire (this is documented in the installation instructions for your bike). Unfortunately it does not work with Power Commander 3.

WHERE IS THAT SWITCH?

[KaldekBoch]

@Aldivine LOL, I fitted it myself. All you need is a switch from an auto parts store and wire it into the "switch" sockets on the Powercommander V. Then you just reconfigure the Powercommander so that the Autotune is turned on and off by the switch. I mounted my switch on the inner fairing panel under the left-side handlebar.

@KaldekBoch thanks man... my AFS is not reading.. have any idea what could it be?

[KaldekBoch]

@Aldivine You may need to upgrade the PCV firmware. I had to do this to mine to get AFR readings to work. Also check the lights on the Autotune box. If one of them does not stop flashing after 10 seconds, your Autotune O2 sensor has failed. Both lights need to be on all the time and not flashing.

@KaldekBoch right on man, I'll def give that a try in the next few weeks,never thought of that. I'll be sure to drinch that rag with carb cleaner.hell, got a fresh can at home! haha thanks for advice. RIDE safe !

[KaldekBoch]

@toyscostmoney10 It's possible for the sensors to fail and go fully lean. Good way to test this is to unscrew it from the headers and wrap it in a cloth which has been heavily sprayed/soaked with carburettor cleaner. This will keep out the oxygen and it should read fully rich (9 or so) when you hook up the laptop. If it goes rich then suddenly fully lean (17 or more) then it's a dud. Just make sure you spray enough carby cleaner on the rag otherwise the test won't work.
