PHASE 2 TEST:

All connections from the GIZMO were attached and powered, the engine was run in closed loop operation at idle. The 02 sensor signal wires were jumpered from the GIZMO, but maintained the original signal wire to the ECU to see if the GIZMO would override the voltage from the 02 sensor to the ECU before I cut them...

I was able to adjust the voltage on the secondary bank even though the GIZMO was just jumpered / tapped into the sensor signal wire without cutting the original connection. If you look at the data log you can see where I turned the pot completely off on the 1/2 & 2/2 sensor bank and it logged .005v.

I did the same with the primary bank and the voltage was altered +/- momentarily, but since it was only tapped into the circuit I could only hold the voltage for a few seconds before it went back to normal...

Now that I know the voltage can be regulated by the GIZMO, the next step is to cut the 02 sensor signal wires to the ECU/PCM and have the GIZMO take over the voltage output...

THANKS WOODY THIS IS FUN.
