I'll check it out - and another question or two
I've been running the level two tune for a little over a half a tank, and I've noticed that the Gryphon seems to be under-reporting vehicle speed. The analog speedo in the truck agrees pretty closely with my GPS but the digital on the Gryphon seems to be about one mph or more low. What is the rounding algorithm? Does the unit round or just truncate the fractional mph?
I'm reluctant to open the custom parameters menu yet and start changing things, so my second question is, what tire size and gear ratio is the unit set up for? I think I provided my VIN to order, so did Bill look up the gear ratio and tire size (if it varies)?
As an aside, even if it is under-reporting speed and distance, my mileage seems to be up. I think the biggest cause is I can see the mileage and how my driving style affects it. So far, I have noticed one counter-intuitive effect. If I start off from a stop very gingerly and slowly accelerate up to the cruising speed (in town) I get WORSE mileage than if I hit it to about 1/3 - 1/2 throttle and get up to cruising speed more quickly. That may be because the towing tune is more efficient at lower speeds, or it may just be my imagination, but I thought it was interesting.
