Hi all,

A few issues im having on trying to tune 2 different LS engines are as follows...

1. Logged data with scanner never seems to be accurate with vehicle conditions. example.... Load tested vehicle on dyno to measure afr, on the ve table im viewing the load never exceeds 20 kpa on the table.

2. IPWV table shows the vehicle to be running at 4.5 volts at all times. The map side of this table changes but the voltage scale is constant at 4.5. On previous vehicle it was fixed at 7.5 volts.

3. Measured 140kpa on dyno and 20 kpa measured on logged data.

What am I doing wrong?

Thanks in advance,
Chris
