TSB #06162C ECM Updates for Virtual Flex Fuel Sensor

[dredmond24]

Has anyone had this update performed yet? I was talking to my Service Advisor today about it. He claims that other customers have reported gaining 2-3 mpg after receiving it. I am scared because I think I will loose mpg's.

Thanks!

If you gain some extra MPGs, then that's a nice TSB then...:thumbsup:

I didn't recieve anything either. It was brought to my attention when my truck was in for an oil change.

Here is a link, that details the TSB:

I've done at least 100 of those program updates. Never heard of gaining mpg's, or losing mpg's. But i don't talk to the customers much. It doesn't change much of the programs in the pcm, just certain aspects.
