I’m trying to track the wiring here.
From the head unit to T harness then all 8 into the dsp(yellow wires?) then Dsp to rca to key 500 and key 200? Then back to t harness.
My first full tank with the lift and level came in at 18.4 mpg hand calculated. I did about 50/50 city highway, I did tow my boat once on this tank for about 6 miles so that ate up about 3/4-1 gallon there as most of that drive is stop and go.
so average that back out and it comes to 19.1mpg...
Install done today. Works great.

You don’t have to do that anymore. Forscan has majorly improved their interface. Most of the menus are just drop down and select now.

I changed mine to 2540mm and I’m really close. Within 1mph at 55...

FYI In forscan I adjusted my tire size to 2614mm which is equal to the 102.9” diameter nitto has on their website for these tires and I went from 5mph slow to about 2mph fast.(odometer compared to gps) I’ll adjust with the mm size down a bit and report back...
This Thread is slightly outdated now so I just wanted to update it. Changing the size in the mm selection now does work!
Some fine tuning will still be required. I changed mine to the manufacturers specifications on the tire and instead of being about 5 mph slow on the speedometer I’m about 2...
