Any owner of a F150 5.4L 4x4 ? I would like to have your input/feedback about this product. Especially if you live where it’s cold (-20 Celsius).

Have you ever got any weird behavior from your pickup when it’s cold, in the morning for example?

I suppose I should sell it then... anyone interested?

Any update?

I did change it 2 times (only recently) in order to fix the temperature issue, which did not.
As for the mileage, I agree that I will not do the same as on the summer time... but I know it can do better than 19-22L/100km

With the 87 performance, the pickup still needs 91 octane to run properly otherwise it stall or rattle a lot when cold. And cold is pretty much all the time at this time of the year in Québec.

That being said, while he was using the 1r08d it was going around 11L/100km, which is really good ...

2010, xlt 4x4 5.4L

Or... is there anyone else out there with the 1r08d update ? I definitly need to test it out again!

Ok, since it appears I am the only one with this issue I'll do it myself some other way.
Now, is it possible to get my hand on the update PRIOR the support of the tranny? I think its the 1r08d...

Can you post it please?

Thanks

It has been removed, but I have been using the 2 lasts, which were G and H. 1r08g and h that is. There has been 1 version that really worked like a charm, it was the version D... the one prior the tranny update.

Anyhow, as soon it get too cold, it doesnt behave normally...rattle and usually stall ...

Hi guys,
I would also add that I tried to get the 87 performance to work and its now actually shutting down when cold (forgive my english). It kind of rattle (?) ... need to put some octane to get it around 91 in ordre to having to work properly.

Help?

With a second note, it looks like the pickup cant get any new program... as if it was stuck on the original.

Is there a way, other than using the trinity, to verify that the program was installed/configured properly on the pickup?

Could the "original backup" be corrupted in a way that you cant ...

I'm working with l/100km here and usually from imperial mpg not US.

That would translate from how much us mpg to how much us mpg?

I'll convert those later

Thanks

Should I see any improvement in the fuel economy? Or am I reading it wrong?

Am I the only one with this issue?
