Speedo problematic, can I have another one programmed to match odo??
Like clockwork, my truck generates a new problem just about every week. This time its my speedometer. I'm hoping there is a fix for this (otherwise I'll consider a replacement). The needle sticks, sort of. Random example... If I am driving at 70mph and slow to 55mph it might stay pointed at 70mph (my SCT Livewire reads 55mph through the OBD2 port). Now I slow down to 40mph to exit the interstate and this time it drops speed with the truck. However, for the rest of the time it is calibrated at 15mph higher than the actual speed. Slow to a stop??? The needle points at 15mph. It does it randomly and to different degrees. Sometimes 5mph off and sometimes 50mph difference. If I turn the ignition off and wait, it will fall back and reset itself.
Is there a fix for this??? If not, I'll probably ebay/craigslist/ORG classifieds a speedometer or gauge assembly. My only concern is losing the truck's original mileage and hour readout. Can it be programmed?
