How do I go about recalibrating the speedoo for a gear change? Liek in a mustang you can change the gear int he tranny and the newer ones can use the speed cal from DMS. Can the speed cal work on the F-150's?

I am putting the lightning rear supension and 8.8 in tomorrow and would liek for the speedo to read correct.

 

superlift offers a truspeed. heard its pretty good. heres a link to it:

you might just have to shop around for the lowest price, but its got good reviews.

 

The F150's '92 and up are electronic speedometers, no gears in the tranny. The speedometer sensor is in the rear end so if you are using the Lightning rear end, computer, cluster and stock Lightning sized tires you should be fine.

 

also the moon has to be in the right spot and you must click your seat belt three time before turning the truck on.

 

Heh heh, gear change. I guess I missed that part. Durrrrrrr.

 

Not using the lightning computer.. Just rear end & gauges...

 

yeah, i'd look into the superlift deal. let us know what you decide!

 

Don't you need to use the Lightning computer for the engine to run right?

 

Shouldn't have to ], my truck is mass air.

 

"shouldnt have to"? lol, might wanna make a sure first.
