Hey there, I did a transmission swap, from a IB5 to a MTX75 and now I'm facing speedometer issues.
The old style sensor was mechanical snail-wheel type, the new one is magnetic. The speed is about three times too high now.

In SCT Advantage I adjusted System Switches --> Scalars --> Number of holes for OSS Sensor.
Stock value was 8.84, I set it to 26.52 (mutiplied by 3). Speedometer started to read correctly.
But now everytime I flatout the speedometer goes off and odometer goes "-----". (see vid below)
It comes back if I cycle ignition.

Am I missing something?

Maybe the software map doesn't read that high, no need to with the way it was before.

Computer may well go to infinity, the software though has limits.

Ask Tom, He could likely fix that.

That's what I thought.

Maybe I will need a speedometer signal interface to adjust the signal before it reaches the ecu.
