U7164 problems
Hi I have a 2010 F-350 6.4l. I just got an U7164 and I had a problem loading in the performance section. I received the following CALID numbers:
First unit: 8U7A-14C204-HCC
Second unit: 8C34-14C337-DC
Any help would be great. How do I find out what the current update on my U7164 is?
Thank you.

Re: U7164 problems
Thank you!! Worked like a charm once I figured out how to update the tool. Is there no option to change tire size with this tool? I saw the tires revs per mile but no tire size option? Please let me know cuz it would be nice since I've received two tickets in the last month. Lol. Do u know what tire revs I would need for 285/75r18's?? Thanks again and I'll keep u informed on how the tune is working.
Re: U7164 problems
Never mind. I spoke w someone on the phone there and they gave me the ratio. Thank u for all your help!! You guys have been very helpful!!!!
Re: U7164 problems
Hey Mike. How many tunes does that update u sent me (9t18a) have? I thought I saw economy, tow, performance, and extreme? What does the performance one consist of? Also, does the tire revs per mile recalibrate my speedo or is it just for shifting? So far I'm loving it!! Thank u for ur time!!!!

perf is for safe power increases and mpg gains while not towing.
tire size should calibrate the speedo

Re: U7164 problems
Well I'll look again for the tire size. All I could find is the tire revs per mile. Didn't see anything for tire size change. Thank u for the extra tune!!!

Re: U7164 problems
Ok cool. Just wanted to make sure. I read on a forum that revs per mile was just for shifting so hearing from u makes me feel better!! Thank u very much!! Have a great day!!!!
Re: U7164 problems
Should I see better mpg with the economy tune or the new performance tune? I've heard some of the higher hp tunes are better w mpg. I haven't tried the new performance tune yet so I'm just curious. Thanks.

Re: U7164 problems
yes, if you keep your foot out of it, the higher power tunes should show solid MPG gains.hockey21 wrote:Should I see better mpg with the economy tune or the new performance tune?
