Pretty sure I see how to do it, but the map is a 20x20 block and hitting around 17psi I am at the 19 block. Just put in a 3 bar map sensor and adjusted the PIM reference, but to actually go higher I am guessing I have to change the map reference specs for PIM as if I am changing the rpms to go higher than 8K. Anyone have the values they are using up to at least 22psi? Seems the stock has 1K increments until block 16.

 

To add more boost P rows, you must eliminate/remove some of the useless rows.
Most stock engines idle in row 4. Thus it is easy to remove rows 1 - 2 by moving the current rows up for all three maps. That allows adding 2 higher boost rows.

Then the low vacuum rows used only for acceleration from cruise to boost can also be removed.
Same idea can be used for rpm columns.
I added a little for both for my calibrated Apexi/Denso 3 bar.

Just calculate the ABS PIM values.

((ABS-PIM/10000) * 14.22) -14.7 = psi

 

So that scale goes to 15.7psi?

 

I always use row P20 as an over boost row with low timing and very rich fuel. I do this even though my EBC has over boost protection. Safety first for our touchy engines.

My 4 boost rows that my EBC allows are exactly 2 psi apart.

P16 = 11.8 for running 12 psi
P17 = 13.8 for running 14 psi
P18 = 15.8 for running 16 psi

P19 = 22856. (22856 / 10000) * 14.22 - 14.7 = 17.8 for running 18 psi boost.

P20 = 24262. (24262 / 10000) * 14.22 - 14.7 = 19.8 for 20 psi over boost.

Due to much testing and calibration which very few people or tuners do but I do/did;
(1) I always first calibrate my map sensors. This insures that the values calculated by the PFC are correct and accurate compared to my expensive calibration
pressure gauges. The stock scale/offsets can be used but they all are inaccurate! They give low results.
(2) With a 2 bar, when boost is climbing and reaches .25 psi below the next highest ABS value in the table, it starts to use the next row a little.
Extrapolation can be seen on a log as a few hits in adjacent rows.
(2) With a 3 bar it happens around .2 psi.
(3) By trial and testing in the past for my 2 psi rows running calibrated values, I can get my PFC to only run in the boost rows for which boost I select.
My Blitz EBC with active feedback control can actually keep my boost very linear once boost reaches the set target boost.
