New ficm/oil cooler/egr delete question

**custom4584** · #1 (**permalink**) 11-20-2011, 07:01 PM

Put a new oil cooler on and did an egr delete while I was in there, after I finally got it started it ran really bad for about ten minutes. Then it smoothed out for about ten minutes, and now runs like crap again. Is this still air working out of the system? It ran a good twenty minutes and still sounds like its missing. I also changed out the ficm and now get a "u0306" code. Ficm software not compatible. That's the only code it's got. Would this make it run bad, and do I need to have the ficm calibrated?

That code pretty much means the FICM needs to be reflashed.
I would imagine it could make it run like crap.

Ok. I'm thinking maybe there's still air in the hpop then?

A few wide open throttle runs will purge it out of there.....

I can do that to hear the new exhaust! How do I know what strategy was on my old ficm to put in this ficm? Is this something ford will know what to do or do I need to find out what needs done?

The strategy of your old FICM can't really be determined without having the old FICM in hand and a device that can read it.
What FORD will do is update the ECM and the FICM to the latest strategies.
By the way, you will probably lose a little power and a little fuel economy after FORD does this reflash. The newer strategies were created with emissions standards in mind and not power/fuel economy.

So I should just leave well enough alone?

Not if your truck Runs like crap... Plus there is several places that have older strategies you can buy still.
