I determined that I I had not calibrated the Ego sensor in the calibrate sensor menu of megatune. All is well

I have verified all the LC-1 grounds are tied together & 3.7 volts at AD5-1 on MSII daughtercard. This voltage should equate to 18:1 A/F ratio however Megatune reads 12.1. Logwoks2 software does show 18:1 & the LC-1 is working properly.

During a portion of the dyno run I see A/F ratio jumping up ...

Thank you very much for the reply Richard. The grounds were definatly a good idea, however I double checked them & they are tied together.

I do have a 3.6-3.7V signal at AD5-1. This should be around 18:1 A/F using the default LC-1 calibration of 7 to 22 A/F = 0-5V.

Attached is a PDF graph from a ...

System: MSII, embeded 2.32, MT 2.25, V3 main board, Innovate LC-1 wide band.

I have the engine running on a dyno at a steady condition.

Using the logworks software supplied with the LC-1 wideband O2 sensor the A/F ratio is reading 18:1 and flickering a little as it should be. Megatune however is ...
