My car has VAPS (Variable Assisted Power Steering) which uses vehicle speed (from tanny) and other info to determine the amount of power-steering (slow = more assist, fast = less). I only discovered this after yanking out the old EEC-IV and installing MS2.

I have two options:

#1 - Rip out the VAPS steering rack and install a reman non VAPS rack.

#2 - Hunt down the brains of VAPS and see if I can piggy back inputs it needs... (screwed if it's part of the EEC-IV).

Has anyone else had this issue?

Thanks

VAPS is self-contained and does not communicate with the ECU.
