So Ford has finally come up with a calibration they believe will fix the misfire issues during damp rainy conditions. This new TSB was released the end of January. The best part about it is that they want us to take off all those air blocking plates from past tsb's which should bring back the coolers efficiency. Now this is only for the 2013-2014 models but hopefully soon enough there will be the same calibration fix for the 2011-2012 F150's. I also clarify the air cooler engineering numbers for all model years!

 

This is great news, I have a '13 with the upper deflector, and what looks like a lower scoop looking thing that is actually part of the airdam. I live in Northern California, where humidity is not an issue, and where the misfire is unlikely to happen but would like to get the updated tune, and have the full effectiveness of my intercooler.

Do you know if they will perform the TSB on a truck, that does not have the misfire, but has the blocking plates? Also, does the new TSB restore the claimed "de-tuned" portion of the programming people say the '13+ trucks have?

 

Very interesting, thank you sir. My 2011 has never displayed any symptoms of any kind nor has been worked on. Sounds like the 2013-2014 trucks are going back to the stock 2011 intercooler design but with a PCM flash. Progress is good.

 

Just go into the dealer stating you are having misfires in rainy situations when passing someone and they should do the tsb, we do them no problem. I contacted the ford engineer hotline and they said they didn't even have the specifics on what's changed.

 

bump. I want to keep my eye on this

 

I for one REALLY appreciate you posting these videos up for us and applaud you for taking the time to help us all out with the newest info etc. I tried to rep you but I am in rep jail again.

 

Got him for you Rob!

 

x2, thanks very much for posting these up here also in rep jail

 

Awesome thanks guys!

 

The '13 and '14's don't have the same intercooler as the earlier models. The internal design is different. So even if the shields are removed you still don't have the cooling of the early models. I have a '13 and I dumped my stock CAC for the Wagner. IAT2 temps are way lower now.

What will be interesting is to see what the new flash brings. Since the Ford's have larger turbos there is potential for more power. Maybe Ford will not only give them back the power of the earlier model trucks but actually increase it. Like getting a free tune
