I have a 09 classic with a PC5 but without the O2 sensors. I thought i had the auto tune but was told you need the O2's to be a true auto tune. totally confused!

 

You need the Autotune add on to have autotune. The autotune works of the 02 sesnors.

 

Yep, the autotune modules with the bosch O2 sensors cost another $300.

 

Great! another 300 clams, but the bike works great, a little rich maybe so what can i expect.

 

Autotune is an add on module that adjusts as you ride. You replace the OEM O2 sensors with the bosch ones in the kit. It adjusts as you ride or change parts. If you are happy with what you have leave it alone. Or have whoever you bought it from adjust the map. I have the AT module and really like it but it isnt necessary.

 

Get in touch with Jamie from FuelMoto and maybe he will be able to help you with a new map for your setup that won't be too rich.

 

Well i have been living with this sinse last year and once in a blue moon it will spark knock under power and sometimes when i blip the gas gearing down but with what i got in it it works great and decent on gas so i see your point, if it ain't broke don't fix it and spend more money than you have to.thats a good idea calling jamie, see what he says.
