Gryphon ordered! But have a couple questions.

I wouldn't worry too much about the stickys. We'll get it on the website and in the manuals and stuff. The worst that happens is they go to Corey anyway and she gets it in her regular e-mail.

If someone wants to change 'em, that's fine. Don't kill yourself to get it done though.

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).
