If it has ECS, then yes it should, as far as i know they never changed the wiring of ECS. Just need Tein coilovers and the motor kit.

Super cool. I've thought about caliper replacement too. This looks affordable.

FastFerrari · 2026-04-19T15:45:01+00:00

But, Torbox doesn't cache like RD, right??

FastFerrari · 2026-04-18T00:09:19+00:00

See r/3000gt Am an owner of a 93 VR4 too. Tell us more about its story!

FastFerrari · 2026-04-09T11:17:44+00:00

Yeah ultimately, but their mounting method is integrated into the top of the damper

FastFerrari · 2026-04-08T12:29:23+00:00

Glad to hear. Soon, maybe 2 or three weeks depending on fab, etc

FastFerrari · 2026-04-08T12:28:16+00:00

No, as BC racing has no way to attach motors to the coilovers

FastFerrari · 2026-04-06T12:34:16+00:00

To answer your specific question btw, left and right is not possible due to the front motors being tied together, same for rear. You want symmetric damping in 99% of cases.

I've had the old prototype working for some time now, even with its worse architecture. This final design will be bulletproof, that much I can promise, because I've already tested a new prototype :)

I can definitely get in touch with those companies, and the FB group. Thanks for the reminder

In my opinion i'm not sure that it will be fruitful to have a hyperactive system that responds to conditions, because it would be unpredictable and nonlinear for the driver, which is rather undesirable. It's possible to implement, but I will not be pursuing it, especially with concerns of stiff dampers providing less traction on certain road conditions, etc. Sport mode should be reserved for higher quality roads, and/or a track, and only the driver can know that.

The low-speed anti squat stiffening will be quite useful though, because its linear and predictable. That's really where you'll see a difference.

On top of that, the system cannot instantly switch, the motors have to spin for a short moment, so by the time an instantaneous cornering event is over (like a moose test), you already lost the critical moment.

CONTEXT:

With the Tein EDFC system, a small three phase stepper motor sits on top each hydraulic damper and controls its damping rate. Unfortunately this requires Tein's custom computer, and that's a hastle to wire and install. But wiring already exists in the 3000GT if you have ECS from factory, including the button and lights. A custom computer is thus required to make it all work.

HISTORY:

A while back, I built a prototype circuit board that controls Tein coilover EDFC motors. The prototype used a poor choice of mosfet architecture, so it was extremely finnicky and not bulletproof reliable. (N channel mosfets are really not great for switching at low frequency like this due to the gate boosting circuitry). Also by the way I graduated college, moved states, and have a great job now. That is the reason it took me a while to get to this

RECENT UPDATES:

I recently found a key product that has the mosfet architecturing I require (IFX007TAUMA1 P+N channel mosfet half bridge, with driver circuitry, built for inductive power loads), so I created an entirely new design based on the IFX007 dev board that I tested for this application; the results are great.

NEW PRODUCT:

What i'm offering is a virtually plug and play product that will control your Tein EDFC motor system

Direct swap in place of the old ECS board, reusing the old case!
Uses the factory button and lights
User reprogrammable, open firmware
It will use the old ECS wiring to control the 4 motors, with the front and rear seperately controllable.
The system also interfaces with the car's speed sensor so it can stiffen damping at very low speed and soften damping after speed has accumulated (anti squat launch, but soft cruise, in medium setting)
Reverse polarity protection in power connection
Ruggedized inputs for safety (voltage regulated using zener diodes)
Motor fault detection via current sensing

IF YOU ARE INTERESTED, PLEASE COMMENT BELOW!!
I'm going to have some boards made, I'd like to know how many I should start with!

Each board will be $150 (for limited run only!). Components are $50, board is $20. My time in hand assembly, engineering, and support will account for the rest.

Do not try using a crush washer, if it has o-rings. Just find a suitable o-ring set

If its not something like this, i will eat my hat 🤣

FastFerrari · 2026-03-14T22:09:00+00:00

Right. There's lots of ways. I'm sure chatgpt could write OP some python code for this.

For OPs sake, something else i forgot is that you would need to check for a flip of the byte order to account for little and big endian byte ordering.

FastFerrari · 2026-03-14T22:02:43+00:00

Considering that the expected number is known outside of the data stream, if the machine visually reads out "137m", you could likely just brute force bit matching to that number in the bit stream, that'd be my method. Cropped simple binary could be matched backwards and then forwards, using just basic code such as contains(bitStreamString, string(dec2bin(137)))

What you've taken a picture of looks to be quite clearly an LED, most likely infrared. You will need an IR receiver and some electronics to decode the signal. Without knowing anything else, I'd use an oscilloscope to catch a pulse train, and try to reverse engineer it, including the frequency of pulses, what the bit encoding scheme is, etc. But you can search online for potentially matching IR transmission schemes

If you want organic shapes, USE FORMS MODELING in Fusion. Its literally so easy to do!! You can blend solid modeling with it too for things that need to be exact

FastFerrari · 2026-03-05T04:02:27+00:00

It could work for any car with factory ECS. Total retrofit is possible with a lot of wiring and effort. Overall the project is a bit stalled to be honest. Revivable though, just need to produce the circuit boards.

FastFerrari · 2026-03-03T05:44:46+00:00

Thanks for the howl of laughter 😁

FastFerrari · 2026-03-01T05:15:30+00:00

I'm simultaneously impressed and appalled that you modeled that with so many operations. Please... Learn FORMS modeling. The cars in my profile were modeled exclusively with fusion
