Sup w/them 2024 Summer Projects?

Im really interested too in whats actually going on through a corner. I only did a 150psi sensor because I think if its over that its probably max or in more rare situation. But I'll be finding out!
Right now it will be sharing a gauge with my oil pressure sensor so as soon as I determine some of my oiling changes are solid, then I'll change the plugs. This is just temp till I run wires for full time logging of it though.

But you also shouldn't be taking advice from them on really anything.

Steering angle sensor has to be logged with this in order to have any meaningful data! Along with the throttle positioning and Gs

First step though, see what the pressures are doing and have fast they swing around.

Couldn't you just log the ACD ecu directly? I vaguely remember doing this years ago with Evo scan and getting things like wheel speed sensor, steering angle sensor, etc. Probably pump pressure is in there.
I also am relocating my ACD pump but shied away from AN lines because max pressure IIRC exceeded typical AN fittings. Safer to run brake line fittings.

As for AN lines, I dont recall the max line pressure but its something over 1000psi. The compression ring fittings do have a limit that may be pushed with the ACD pumps potential. I bought a proper AN flare too and flared the OEM 5/16" EVAP line and used that to run the fluid forward. As luck would have it, the line is about the same length as the OEM line (OEM wrapping all the way around the engine bay and all) and its the same diameter. So it works out perfect. And then the
EDIT: Also to add, Ive had this line in the car maybe 3 years already with not a leak. So it has been totally solid.

One of the things we noticed was that at steady state cornering the acd was open..

There is a small mechanical pressure limiting valve in the pump and it opens at about 15 bar

....about is what the pressure is in context of whats happening on course, what the yaw rates and lateral/longitudinal loads look like. I basically need to wrap my head around what the center diff is doing when the car is acting any given way through the various parts of a corner or straghts.
Sounds like you run better AN fittings than I am (also I don't have a crimper). My fittings are compression type and are rated to 55psi max. I'm also using the evap line to run acd fluid from the back. Just flared and using OEM style brake line fittings.

you could setup an arduino to log all those signals. Or if you wanna be fancy a mixed-signal oscilloscope.

Having said that, first thing that "we" should do is log individual wheel speeds / axle speeds and see if more locking is needed at all..
