I just got my truck regeared to 4.88 and my custom tuned Xcal3 from Justin at VMP only goes up to 4.56. I know he has to send me some sort of update file for me to download onto the programmer for the 4.88 gear ratio, but does somebody happen to have it on hand or know where I can get it fast? Justin must be loaded down because he is taking a while to respond. Is the file even universal or does it have to involve the custom settings for the tunes I have? Driving around with 4.88's with no programmer is fine, but I want to correct my speedo and shift points and everything...not to mention the power and it's driving me nuts

Thanks for the help guys!!

 

I thought 4.56 was as low as you could go?

 

He will have to change the limit values on the gear ratio and send you new LL3 files.

 

I had 4.88 gears in my sport trac with an Xcal 2 that only went to 4.56.
Doesn't really matter though. I set the gears to 4.56 and found the appropriate rev's per mile to get an accurate reading compared to GPS, then confirmed it with radar
