speedometer recalibration ?

If that thing can do it, surely it can be done with EFI

EFI cant do it because that is in the TIPM.

best bet is to find an old smarty, you do not have to reflash the ECU

You can change it with hp tuners, I didn't think efi live was that different

The speedo is done in the abs module. I have open box products if that helps.

Ive always wondered the details of that flashing process... does that have anything to do with going thru the tipm or does it flash directly to the ABS module? I have always wondered why EFI cant acess it... sure would make a lot of customers happy
 
just find someone with a smarty and give them 40 bucks to do your ABS update on your truck
 
EFILive can not update the speedometer.

The tire size should be changed in the tune to get the load calculation correct.

I use a HyperTech speedo recalibrator from Summit Racing.
