So what’s that saying " Engineers just love to change things"
- well just could not leave well enough alone. I have just about finished a new Model 03 of the Mitsubishi 3000gt Suspension controller and I’m in the process of writing the new control software.
the new Gen 3 will do everything the Gen 2 design did , but it will have an Automatic Strut Control Mode that will use 3 Axis accelerometer daughter board that is part of the controller. The Accerometer used is the integrated on one used in the LSM303DLHC.
The automatic mode control algorithm will dynamically control the 3 stiffness settings of the 3000gt Strut Cartridges based on the motions of the car. For example if the car starts braking - the Control algorithm will stiffen to the two front struts to help mitigate the nose of the car from pitching downward.
This will match the capability of the original OEM system had - but without having to use any of the original car sensors ( Throttle control , Brake pedal, Steering wheel angular sensor etc that often fail in the 3000’s).
Here’s a PDF of the Schematic for the Design:

With the Hardware design done - I’m working on the software algorithm but I needed test data for what the acceleration profile will look like for a 3000gt Vr4.
So I added a Sparkfun OpenLog SD logger to be able to record live Acceleration data .

We did several runs and here is just one Axis of an acceleration run (12 seconds in duration) of a 3000gt Vr4.
you can see that at about 6.9 seconds into the run the car achieves a max acceleration of almost 0.75 g’s
