  • Replaced Whiteline 30mm solid bar with Eibach 32mm hollow bar
    • Whiteline bar: 19lbs
    • Eibach bar: 11lbs 
    • In the pic above (click to make it bigger), note the superior features of the Eibach bar:
      • Welded on discs prevent the bar from sliding (I added the metal stops on the Whiteline bar)
      • Uses the factory mounts (with new bushings)
      • The new bushings are asymmetric and include a part that butts up against the welded on disc - very thoughtful design
      • Finally, everything bolted up as expected.  In contrast, I had to buy a special drill bit to bore out the endlink holes on the Whiteline bar. 
  • Re-configured the catch can setup to vent to atmosphere instead of plugging back into the intake manifold.
  • Improving the EPS power assist
    • Turns out that the EPS expects a lower-pulse rate than the VSS provides. 
    • SOS connected the VSS directly to the EPS input and called it a day.
    • To return to stock-like effort I ordered a 1/40 pulse divider from Race Technology per the advice of "stratocaster" on s2ki (thread: http://www.s2ki.com/s2000/topic/828592-power-steering-eps-and-aftermarket-ems-problems/).
    • On AP1 cars, gauge connector C has the relevant wires.  Blu/wht on C3 is the input from the VSS and wht/blk on C1 is the output to the VSS.
    • Blu on C5 flows from the gauge cluster to the ECM and the VSS - what does it do?  Service manual shows it's a tach signal and SOS cut it from the connector - presumably they're tying the ECM directly to the VSS.
    • They are very difficult to access with the dash on.  This will probably have to wait until winter when I remove the dash and slim down the wire harness.
