Down in the file are links to my fuel and spark maps, in VEX format for 12x12 tables, MSnS-E. The fuel is rich and the spark is a little retarded for my NA 16 valve 4age. The car ran ...

When I initially set up MT I had the settings wrong for the O2 sensor and the voltage would rise up to about .7 or so and basically stay there. After reading the instructions in MSTweak for getting a good datalog, I changed the settings and it started bouncing ...

My car was running fine, but rich, and I was playing with the tuning wizard, changing values in the VE map, and my O2 readings started bouncing around, like from extreme lean to extreme rich. I tried to restore the original VE values, but it didn't stop the bouncing.
