I have the same issue, I blame both my new trailer and I would like more power from the IBC...running on 10 with not enough brakes. I have adjusted my brakes twice now om my trailer with no change.

Subscribing.

That is the nature of TV MC PSI based trailer brake controllers (also
IBC's) and why the preset is so important. Though also important to
inertia based trailer brake controllers

When the TV brake pedal is pressed...it travels a bit (varies from OEM
to OEM) BEFORE it develops any MC PSI...but most do get the brake lights
turned on BEFORE the MC develops PSI

The preset determines the starting level of voltage sent to the
trailer brakes. Or the minimum voltage sent, once told to turn on

Below is my opinion from reading up on IBC's when they first came out
and do not know if they have changed


Then the MC PSI takes over and the hysteresis is preset by the OEM
for the IBC's voltage to the trailer brakes

The amount of voltage sent is determined by the MC's PSI. Press hardere
and the IBC will send more voltage

With an inertia based trailer brake controller, once there is *ANY*
deceleration, the inertial sensor will take over with the preset
as the LOWEST starting point.

The MC PSI only manages this via the more you press & brake the TV,
the more the inertia sensor will tell the trailer brake controller
to brake more (more voltage sent to the trailer)
