Tunerpro defenitely is not the right tool for mode 4 control.
It is such a pain to use it.
I got very happy when I saw you`re working on this new software.

Here is the commands you may be interested in

SET BLM to 128
20 00 00 00 00 00 00 00 00 00 00 00

It is used once
If you want to run it again send
00 00 00 00 00 00 00 00 00 00 00 00
and then
20 00 00 00 00 00 00 00 00 00 00 00

Forced open loop use this
00 00 00 40 00 00 00 00 00 00 00 00

Forced closed loop
00 00 00 40 40 00 00 00 00 00 00 00

BLM update (LEARN) disable
00 00 00 20 00 00 00 00 00 00 00 00

BLM UPDATE (LEARN) FORCED ENABLE
00 00 00 20 20 00 00 00 00 00 00 00

I think BLM enable was labelled wrong as open loop so you can check what you have on file
Anyway these are the correct settings
