6 Speed swap ecu problem

[loudawg777]

I have a 2013 Sonic LS 5 speed. I swapped a MZO 6 speed from a Cruze. The 6 speed has a different pick up wheel for the speed sensor. This is making the speedometer read very high. Dose anyone know anyone who can hack the ECU and calibrate the speedometer????

I don’t know anything about the ECU, but maybe a tire shop could help? It’s like you bought a much different tire size and need to reset the speedo. Just a thought.
