Anyways. So... long story.. when removing power to the cluster the cluster looses its calibration memory so it doesn't have anything saved. This calibration is the "MAX" and "MIN".. It needs this as part of the EVAP system. So on first reset, cluster only uses the Resistor level sensor only to calculate fuel level. Once it goes into one fuel cycle .. from Full-ish to empty to back to full.. then its fully calibrated it starts using other data bits coming from the ECU saying its fuel usage...Its part of your "fuel economy" in your cluster. By any chance is your fuel economy working? That is a special data that Each engine kind is a bit different.
Wait so besides in your swap you get ABS/ AC errors and stuff? Did you wire those in or was that a kit?

I wanted to let you know that I got in contact with Pure and their Motec guru and YES, you are absolutely correct that the "fuel economy" affects the gauge reading. There is a value on the Motec that needs to be adjusted so that the Fuel economy reading is accurate with what the LS motor is consuming. I was able to adjust it to be really close to the real MPG I am getting. Last tank it showed accurately. Will run one more tank really close to empty to confirm it is all fixed.
Thank you very much because I would have never thought to ask the question had you not suggested it!!
