Timed vs inertia brake controllers

how I've noodled this before deciding on the P3...

True proportional braking using 'real time' feedback/sense...the inertia
sensor

Proportional after or above the preset gain

Proportional because the inertia sensor senses rates of change and
the harder the trailer brakes decelerate, the more the P3 will tell
the trailer brakes to brake (voltage)

Since the GM TV brake pedal switch is so nifty, it switches over with
less than 0.010" movement.

That means the brake controller will tell the trailer brakes to initiate
before the TV MC ever develops PSI. Meaning my P3 will have the trailer
brakes initiated before the integrated MC PSI sensed and after market
MC PSI sensed

Can take my P3 out of my Suburban and install it in anyother TV that
has the harness (compatible). Can't do that with any MC PSI sensed,
both after market and 'highly integrated'

Saw how the after market MC PSI sensed HOW2 video and telling to me
on their engineering fastidiousness or lack of it. To have the added
'T' and the stub line to the PSI sensor unsupported in a cantilevered
position on a high vibration application so telling...to have me wonder
what about the rest of their design/designers ??? Oh, they don't
instruct to bleed all the way down to the two corners of 'that' MC
line that was opened. Also telling on the fastidiousness of those
who say not needed and just bleed the stub line...

If my P3 goes south...nothing else is dragged south with it. Since
life time warranty, can get a new one just about anywhere and if not,
then buy another to then send the unit & new receipt for warranty coverage

There is a new thread where a guy hooked up a scope and found that
the signal to the trailer brakes is PWM...not a stretch to see that
there are lots of things that can be with that PWM signal... Yes, am
a designer and have lots of PCB design experience...

One down side is that it looks like after market, but since I keep my
vehicles forever, will be making a wooden center console and then
integrate the P3 into that.

Price is NOT a major consideration for this kind of safety system
but nice to find my P3 on sale for a fraction of the MC PSI sensed
after market units




PS...I've never installed nor driven a trailer brake controller that
used MC PSI sense...but an good in noodling how they work. Pure logic
flow or truth table diagrams in my mind married with the forensic's or
call it failure modes in my mind :)




PPS...looked at the Jordan when it first came out and the spec's seemed
wonderful and actually considered one

But, after seeing how the wire is mounted, where, etc decided that was
had a risk of getting snagged or bent. Plus a moving part, so a wear
point for both the wire length and whatever is inside the unit sensing
wire movement. Asked if there was a rate of change and the guy didn't
know what that meant...cinched it for me back then




PPPS...About the proportional braking of a MC PSI sensed and then
note to them that it is only proportional to the MC PSI, not the rate of change of the TV/Trailer

Or that an inertia sensed does that and dynamically too boot all the
while never developing any MC PSI

Or that when my TV's brakes are told to initiate...gets up to temp to
then 'haul @ss' down in speed...the inertia sensed will see that and
if not up to full voltage...will up the voltage to match

Often will have to let up on the TV's brake pedal to reduce MC PSI
and the inertia sensor will continue to apply high voltage to the trailer
brakes...a MC Sensed will reduce trailer braking because the MC PSI
has been reduced or removed all together...my P3 will continue to brake
the trailer in that condition
