Question SD map sensor vs RPM VE 96531706

Whats up guys.
I have a problem on SD.
Car
Evo 8 (96531706 rom)
Rc 1000cc injectors
S2 cams
Stock turbo Evo9
Aem 320 lph
map JDM 3 bar
fuel pump gas
No boost leak
New spark plugs
New O2 sensor
_____________________________
I now the best settings map sensor VE vs load must be 1:1 and RPM VE must be flat.
If I raise RPM VE (500-1250rpm set to 80) - AFR 10.7-11
I have a log of work on idle and WOT.
Tell me I'm moving in the right direction?
If not, what am I doing wrong?

You'll find the problem after you fit a fuel pressure gauge.

Your RPM VE settings are not correct.
At Idle your RPM VE should be any where between 90 and 80. Leave the rest as stock.
Start playing with MAP VE to get better AFRs.

Did you read Scheides Guide for SD tune ? If not please read it again.

Also ensure your fuel trims and injector scalings are in check.

Start by sorting out your injector scaling and latencies otherwise you will never resolve the issue.

Then work on your MAP VE (which seems quite off...)

RPM VE should only be for fine tuning purposes...
