Turned into an Edge for sale thread....

Just installed my edge evo cs today. The only thing I changed was tire size, to 35x12.5x20, however my speedomter seems around 10 mph too fast. Any idea why this may be? When changing the tire size it said Enlish, and then gave an example of 35/10.0/16 so did I put in my tire size correctly? If not what did I do wrong? Thanks guys! Love this thing so far besides the speedomter.

Week 2 with my Edge and I have to say I'm loving the difference. Currently running the level 2 tow mode.. I'm not looking for too much power, however this has given me more than I expected already.. I am going to replace the fuel with the 93 octane to try out the level 3 setting.

Did you check your gear ratio

Brady_bot

Yep, gears were set to what they are. Little confused.

Should I change my tire size? Read somewhere that you need to add in the "squish" at 4%, so maybe 33.5 or 34 instead of 35?

I played with mine and my GPS until I got it right.

I had 33s and when I used 2646 I was off by about 6 @ 70. When I adjusted to 2608 I was on when they were new and 2604 when they were worn.

I've heard of a lot of people doing this and IMO it's an incorrect assumption. The input is based on the tires circumference. The circumference of the tire doesn't change wether it's a perfect circle or an elongated oval. Factoring for "squish" does nothing.

I am about to install my Edge Evo. If I run it on level to do I need to use the 89 octane or can I stay with the 87?

BassAckwards

You can use 87 on all tune levels except level 3 which requires 93 premium.
