93 s13 redhead sr20det garrett ar/80 (t25?)

i have greddy fmic with hard piping.

while driving and looking at my apexi avcr boost controller i have the boost set for 0.80 kg/cm2 but when im monitoring getting on it the best i can get is 0.6x or a VERY low 0.7x never have i seen it touch 0.80 it mostly stays 0.5x - 0.6x Also the duty is at 37% should i put this higher? what does it do or should i set it at?

whats going on!?

gain affects how long the wastegate is held shut in order to get to your boost target quickly. To much gain can result in boost spikes do to the wastegate no opening fast enough to regulate boost pressure.

Okay...

I have AVC-R and it is amazing...you just need to learn how to use

Go to settings and pick A or B (whichever you are using)

Turn SELF LEARN on for all 5 gears

Give it a reasonable duty to start at (maybe like 55% or so for 0.8 bar or so)

Then get some pulls in from 2500-redline in like 2nd gear or in third gear from no boost....

After a few pulls, it well automatiucally adjust duty at each RPM (if 55% is a good initial guess) so that it tries to hold 0.8 bar at all the RPM values)

When it suceeds in doing this, it will display "***" under boost duty under settings when you select A or B
