Spartan Tire Calibration

[rlpzzz]

At on time I heard there was going to be an update to allow users to calibrate tire sizes via the dash daq. Did anything ever come of this?

That would be very nice! I hope it happens soon....

Talked with Spartan yesterday and they said to get calibrated tunes for larger tires you can only program 3 tunes with tire calibration, you will have to record 3 different speeds from your speedometer & actual GPS speeds and let Spartan know. Hope this helps

And I assume there is a fee?....

[gregw338]

Nope, I am computer illiterate so when I send in my Dash Daq to get all the updated files I am going to have them update the files with the tire calibration.

Hmm, if so that is sweet. I will need to get mine fixed next week for bigger tires.

An on-screen tire size correction solution is very high on our priority list right now for development.

The reason currently that it is $100 for 3 tunes is due to the files currently being written by hand, and delivered as a full custom tune. Basically, it ends up being the same amount of labor as if we were building a tune for a truck with extensive hardware modifications.

Our method of recalibration doesn't involve just one module- both the engine and transmission files are changed. The benefits in this are that not only is the speedometer corrected, but all shifting parameters and N/V (related to axle ratio and tire size) load changes with the engine calibration are corrected likewise.

With the time spent on the latest V3 updates and 6.7L tuning development, it has taken longer than originally intended to get all of this incorporated into the Phalanx Console on-screen, but it is coming

Thanks for update!
Any sort of time frame?
