Ok stock comes soldered from the factory 3,4,5 and 7. Pay attention to what i circle and say in the pictures. NOt the actual picture its just for reference.
Heres a list i put together
This is what i got from my testing, the resistor on j2 needs to be placed no matter what. These are the switches that need to be open or closed.
18s with j30 rear gear
switch 7 soldered
all others open
18s with stock 4.08 rear
switch 7 , and 5 soldered
all others open
17s ie 245/255 35-40 sidewall with stock 4.08 rear
swtich 6, 7 soldered
all others open
stock 4.08 rear with stock wheels and tires 205/55/16
switch 6,7 soldered
all others open
These settings should be pretty spot on, at worst 1-2 mph off. You can fine tune it adding more or less percentage but that should pretty much get you where you need to be.
