thanks for the update. Headed on a road trip soon. I'll update my X4 and post my findings: 5.0 stock using 87 Octane Canned tune.

Have you noticed a downshift issue. Going 3-2-1 opposed to 3-1 like stock? You should be able to feel the trans catch 2nd on the way to a stop. I had this issue with my canned 87 but have since gone with a custom tune to correct the issue.

well I have good news and bad news
good news: the latest update from SCT worked and my truck can now use the canned tunes without the fan on 100% of the time
bad news: the canned tunes SUCK. they made absolutely no difference at all on my times at the track.

Canned tunes did not impress me one bit, custom tune is the way to go. I have 6 of them, first 5 are from 5*, last one is MPT, I'm stuck on the last one as it is the most fun to drive.

I have been saying I was going to get custom tunes for 2.5 years now, basically ever since I got my tuner especially after I found I couldnt use it due to the fan issue. But never got around to doing it because I am worried about warranty issues.
I work for a Ford dealer and should something go bad, you would think it would be easier for me to get it taken care of. but truth be told it's harder because the "powers that be" say as employees we should know better than anyone.
I took the tunes back out last night when I got home and honestly dont think I will put the canned tune back in. I knew I was going to the track last night (although that would technically void my warranty too) and I was just curious if it would actually make a difference in my elapsed times.

If yours is the X4 there is no issue now. I have the latest update as of now.The SCT 93 tune is the best of the canned tunes. But since I have discovered SSI tunes, Gen2 newest of their tunes, I haven't looked back. I am running the 87 version right now and there is no comparison.

Technically any tuner used, canned or custom will void the warranty should a problem arise and it is found without a doubt the cause, google Moss/Magnuson act, but given there is no easy way to show the vehicle has been tuned to begin with it's a moot point.

I have IDS and have searched thru all settings with it to see if I could find some evidence that it was tuned (yes with a custom tune active) and couldn't find anything that would throw up a red flag.

If you're still concerned about powertrain warranty see this link, http://www.stage3motorsports.com/

Yes I bought that because I was also concerned about warranty.

This seemed interesting. Takes a dual processor lap top.




Ford has 2 different interfaces, the VCM which is the factory scan tool from 1996 thru 2013.

The VCM2 is a newcomer with capability for the newer Can systems expected to come out on newer cars.

Bosch builds the VCM2. It is supposed to be backward compatible and so far, the bugs seem to be worked out.

Either scan tool requires a software license to operate the IDS software program. Each laptop requires a license.
Ford sells the license for 1 year for $699.00

Flashed my SCT today. Loaded 87 Octane, with 610 r.p.m for tire size. Fan does NOT stay on. Issue fixed. Thanks SCT for taking care of this.
