BACK TO TUNING - AKA "Which way do we go, AE, SA, PE, VE, AFR?" Un-huh Un-huh!
As I mentioned earlier, I started with a "mail order" tune and wasn't happy with it. Then I went to Dave w and started really tuning with data logging. We started with the same SA table as Harris had. It's pretty aggressive but, again, the 7747 only goes up to 3600RPM.
Here's the "Main Table" from the EBL. Notice I flattened out the advance when near idle because I was having a hard time getting it to stop stumbling @ idle.
Plus, the EBL has an extended table that goes up to 6375 RPM but, I run out of springs and cam when I get up any higher than 5200RPM.
Here's a spreadsheet, I stole with pride, from @84ELKY who posted it on thirdgen.org and gearhead-efi.com, you set your all-in advance and adjust limit advance/increase Kpa, then you can go into the cells after max SA to reduce/increase drop off. The table above came from this workbook.
