Hi, am new to this forum. 1st all I have to say this forum has helped me out many times on my 1999 and 1997 S10s. Reaching out because I’m stuck on this one..., my 1997 S10 speedometer is reading way fast. 2.2l automatic, ext cab. Has factory size tires on it and correct rear gear ratio (4.10). I’ve replaced the VSS, and have changed the cluster. Still getting the same result. At 70mph on my GPS, the speedometer on dash reading 100. Doesn’t matter what speed it reads fast. The slower your going it’s still fast but the faster you go, the farther it is off. I took it to a local performance shop where the guy with his laptop using HPtuner, couldn’t get it to change. He’s telling me from the VSS to the ECM is reading right, but from ECM to cluster he can’t change it. Need help on this please. Is there something else other than the ECM that could be causing this?
