What are you guys doing?
This is my band-aid solution:
Step 1)Right now I hit the bottom line 1.36 g/cylat 8psi boost. So i set my main table to that 18 degrees.
Step 2)I set BOOSTPE to 1.2(12.2afr) up to 8psi then 1.25(11.7) up to 12psi then 1.30(11.3afr) up to 16psi, then 1.35(10.9) up to 21psi
Step 3) Using the Spark AFR Correction table zero it out, then starting at the 1.25 line add -2 degree, 1.3 add -4 degrees, and -6 degrees for 1.35
verify.
8psi commands 18*
12psi commands 16*
16psi commands 14*
20psi commands 12*
If only the Spark AFR correction table had more resolution or had an adjustable axis for PE labels. you could get away from dropping the afr so much.
This with the IAT table makes it douable. and if you're a big dog like 5_litr, you could always start with 16psi, the crank it up to 21+ oke:
lets hear what you have tried. and i know, just scale the tune 50%, but i always end up with idle return issues doing that. cutting ifr and doubling stioch works flawlessly except the 1.36g/cyl spark table.

If i half the value will it double my resolution on all my spark tables?
