[Diy_efi] ABS

Hi Guys (and gals),

I was wondering if anyone has ever played with making their own 
proportioning valve based on ABS.  I have a Mk1 MR2 and the car uses a 
pressure regulator to control maximum braking on the rear brakes to 
prevent them from locking.  A number of people have commented that the 
regulator is set poorly and causes the rears to be doing very little when 
the front are nearly locked, thats very unfortunate in an MR2 which has 
most of its weight over the back.

I was thinking it'd be neat to try putting in an ABS modulator valve, a 
couple pressure sensors, and a 2 axis-accellerometer, which would keep the 
rear pressure at some proportion of the front pressure by using the ABS 
valve block.  The accellerometer would be able to detect tilt in the car 
and adjust the pressure proportioning as appropriate.

Anyone ever try anything like this?
