2015 F-150 5.0 Intune i2 tire size

Post by Warden02 »

I have a 2015 F150 Platinum 5.0. In the advanced tune menu on the Diablo Intune i2 I have enabled tire size change and entered the tire size multiple times in both the sidewall version and the height. My tires are 34.10' tall, 275/65r20 (stock was 32") . Changing the tune has no impact on the speedometer reading. I set cruise on 55MPH, my GPS indicates 58MPH, no matter what tire size I am using. I modified the tune for 275/65/20, 34.1, 35.5, and finally 37" all with the same result. There are no error indicators on the screen, the tune appears to be taking, but again has no impact on the speedo calibration. Does anyone have any idea on how to correct this? I know three -four MPH (faster i go the more it is off) is insignificant to most, but I want it correct.

The primary reason I bought the Diablo tuner was to correct tire size; the HP and MPG gains are a nice secondary benefit but the gains are expected to be minimal on the 87 octane tune so not a real concern.

the last tune written is uploaded. I restored to stock each time prior to tuning so I assume it deleted each of the other tunes.

OK "We have it all tested and proved out. Just trying to get it built and released.

When can we expect the release? This is the main reason I purchased the programmer, it is advertised as being able to adjust tire size, it cannot be returned due to being beyond the return time allowed. So $300 dollars later, patiently waiting, and still nothing........ :blowup:

Thanks for this thread. I bought an in tune i2 Dec 29, 2016 with the same goal in mind; correcting my tire size. No effect on the PCM whether i enter 22" tall tires or 44" tall tires. Not only this, but when I restore the factory tune I have no accelerator response. I'm in a pickle right now.

Once I can successfully reinstall my stock tune I'll be wrapping my in Tune i2 and returning it. And yes, I have tried to update it multiple times. Nothing works with this thing, or at least there is no indication of status update or things working. Very poor feedback on the unit. I'm very disappointed in this product.
