MULTIPLIED WHOLE TABLE BY .844 NO CHANGE EVEN TRIED TO PLOT ACCORDING TO MY DATA FROM RT MON STILL 108?THE IDLE SCREW IS ALL THE WAY OUT TO GET IT TO STAY RUNNING EVEN IN CLOSED LOOP.I ALSO CHANGED THE COOLANT TO RPM ABOUT 150 RPM . :hail:

 

Can you un-caps lock before posting? Thanks.

The KPa (MAP load term) will change depending upon how much load the engine is under. If free reving in neutral then the MAP will drop as the RPM goes up.

If in gear and moving the vehicle the MAP will rise as the load is higher.

So collect some data at various points in the VE table and adjust accordingly. Collect again and adjust.
