Default Edit and MA tuning

To tune in your MAFT settings do you just change the MAF table in edit?
I wan't to transfer my 5% rich setting,then start tuning in the rev range L-terms.

Thanks

It depends where you made the adjustments on the MAFT.

If you made the adjustment to the BASE setting, then you will want to shift your entire MAF table the exact amount that your dialed in your MAFT to

Example: 5% BASE richening on the MAFT = Multiply the MAF table by 105%

5% BASE Lean on the MAFT = multiply the MAF table by 95%

If you made the adjustment to the WOT setting, then you will want to shift your MAF table at all frequencies above 8000 hz

Example: 5% WOT rich on the MAFT = multiply all points on the MAF table above 8000 hz by 105%.

Good Luck,
Kevin

5% adjustment on the MAFT is not the same as adjusting the MAF table by 5%. The difference at higher flow rates between the MAFT and MAF table for the same % is very significant. See below...
