Questions after PHP rollback...?

Hello Everyone,

Well I just did the FICM rollback from PHP and I have a few questions. I followed the directions and everything seems to have worked, the truck starts and runs good and the post shut-down injector buzz is gone.

I was wondering if the FICM rollback changes the strategy on the truck or does that happen when the ECM rollback happens? becuase my strategy is the same as it was before. I am getting the ECM rollbacked on Friday.

Also I am now getting a code when I hooked up my SCT to the truck, I am getting code U0306: Software incompatibility with FICM. What does that mean?

Is it alright to drive the truck?

Thank you for the help.

That is because the FICM code is no longer in sync with the PCM code. Don't worry about it. You are fine to drive it.
