180 km speedometer to 160 km
Hey everyone.
I got one of those APC white face guage things for my Blazer.
As it turns out it is a 160 km/h gauge. the old one was 180 km/h.
now my speedometer is about 10 km off.
Does anyone know what I have to do to change the ECM to read the speed correctly with a 160 km/h gauge?
does it have to be a total reflash of the computer? or is there a way to hook into the OBD2 port and change it? I have an OBD to USB hookup for my laptop that works great so hopefuly there is some kind of program out there that will allow me to do that.
Any help would be appreciated.
