Re: 2005 F150 issue with no idle change after tune
can you attach the last tune written file from the tunes folder here so we can take a look at the file?

Re: 2005 F150 issue with no idle change after tune
The last tune attempt was with the aftermarket head unit unplugged , had read where it may cause issues.
(I stated bone stock earlier , head unit & SWC are the only mods , both disconnected).
Would the KAM cause an issue?
Wondering if installing with the door open would be best , so to keep the KAM off during ignition switch cycles.
Thanks again for the help

the aftermarket radios are not often an issue on Fords, mostly early GM trucks.
KAM wont be an issue, but keeping the door open is always a good idea when flashing.

Re: 2005 F150 issue with no idle change after tune
Hey Mike. Any updates?
Is the issue with the tuner itself? Would a different tuner have the same issue?
I have another i3 Platinum 8145 still sealed in the box. (accidentally two were purchased..)
I started to try the other tuner a couple weeks ago, but did not want to break the seal.
Any info or help would be great.
Thanks.
