Well, the unit is made by TEVES, the model is MK60 I beleive. It came installed on factory BMW M3 cars.
The reasons I upgraded the unit are:
- My stock boxster unit was only 3 channel. Which is one channel for each front wheel, and the rears shared a channel. So if one rear tire started to lock, the ABS affected both rears instead of just the one that was locking. Now, with a 4 channel, each wheel can be controlled individually.

- This unit is believed to have better programing for competition than the stock Boxster unit.

- This unit runs with inputs from brake pressure sensors, one for front and one for the rear, as well as a YAW sensor. I can send this brake pressure data into the CAN stream on my dash and log the numbers for driver feedback as well as technical feedback for the brake performance.

- This unit has its own diagnostic that I can plug into. I lost that function in my car for the stock unit when I removed the factory ECU and wiring harness.

I picked the components up from used parts dismantlers and eBay mostly...
