    you have a MAF. to tune one area of fueling only, you find the particular range of MAF airflow where the correction needs to be made (you can datalog for that). then you increase that value to richen the mixture, or decrease it to lean it out. should be done by percentages (take the value *1.03 for a 3% increase in fuel). when you are finished, you have to view the MAF table and make sure the line has nice smooth transitions.

    I got that concept now and I know how to adjust MAF tables but how do I adjust base pulse width vs load. How do I know where to add or subtract on that table?

    Can anyone help me out on this? How can I find the LV8 number value so I know where to add fuel? And is it ok to play with this table with the the switch left on base pulse width calculation method (X=calc) ????
