I hijacked another thread unintentionally so starting a new definitive thread on this subject.
As 74 Weld Portals start getting put on our 200's it seems the Very Large TIre Situation (VLTS) combined with the way the LC200 handles wheel speed sensors, speedometer, odomoter, ABS, and Trans shift points creates a problem that so far I've not seen a solution to.
I just got portals and 37 inch tires (mild compared to some others) and based on other trucks I've lifted/regeared, I assumed that the regear from the portals would offset the tire size and the speedo/trans/abs/odo would essentially be close enough to stock that it would be manageable. It looks like the LC200 uses wheel speed sensors only for these which means only the tire size and speed affect these functions. The net effect is without some form of calibration the truck is going 10-15MPH faster than it thinks it is at highway speeds and creates several non ideal issues.
I know you guys know WAY more about the LC200 platform than I do. I think this is going to be a more and more common issue as more people put portals on these trucks.
I really don't want a solution that requires cutting the factory wiring harness. Hoping there is some graceful solution that I'm missed scouring the forums.
Spoke to a mechanic and friend at toyota corporate, and he came back with nothing.
Ideas? Suggestions?
