Gryphon ordered! But have a couple questions.

Changed the one in "gryphon programmers" already.

Well I just got my Gryphon today and quickly installed it. I think I can patiently wait on my custom tunes and just leave my truck on 0 (stock). But running level 1 transmission only shouldn't be a problem at all right? Seeing as how it has no engine modifications.?.? While I wait I guess I could try to figure out how to put in my tire size. 35x12.50x18. Anyone have this size and remember the mm value?

[Power Hungry]

Yes, the level 1 should be fine until then.

Tire size should be 2760 mm. That'll get you really close.

Great! Thanks a lot!

I looked through the book again, and decided that I would do the math for the tire conversion just because thats how I am. I went and got the actual specs for my tires off of Nitto's website and its 35.04x13.39x18. Seems wide for a 35x12.50, but thats what it says the actual width is. I have punched in the numbers and did the math several times and it looks like I should be more around 2715 to 2720. Just curious, where did 2760 come from? Thanks, Travis

I've noticed Bill seems to use a "squish" value that is less than what I've found works for me. If the unloaded circumference is about 2793mm, I would actually try 2709mm, which corresponds to a 3% reduction due to "squish".

However, anything you try (and your numbers seem reasonable too) is just a starting place. Plug it in and see how close the Gryphon's speed reading is to a GPS or how close it is to driving a measured mile at a constant speed and dividing the time in seconds into 3600. Adjust as necessary to make the Gryphon match the GPS or computed speed. (The dash speedo usually reads about 3% faster than the actual speed, by the way).

Okay, sounds good. Thanks a lot. Another question. I read that when I first initially run a tune that I should not go in and customize any of the options. Since I don't have my custom tunes yet, I am currently running Tranny Only
(1). I chose no on the customize option. Now, when I go in with my custom tunes OR if I decide to change up and go to the Tow tune, if I chose yes for customize and set up my tire size, is that going to save it for every tuning level or just the current one that I have selected to run at that time? In other words, do I have to customize my tire size for each individual tune level?
