Re: 89-90 200Q performance

[ptimmerm@mashtun.jpl.nasa.gov]

  I've had great results running >2 BAR with the IA Stage II
  on the '85 ur-Q, with 93 octane fuel, over 182K miles on
  the original engine, head never been off, etc. If I run only
  91 octane I do get knock reported by the MSD knock
  sensor and I have to dial back the boost a tad. With the
  MSD knock display I can really tell the diff between 1-2
  octane points on the fuel. I have about 100K miles with
  the IA mod and increased boost.

This brings up the question of MSD, the ignition product.
Multiple Sparc Discharge ignition, which uses a capacitive
discharge pulse string.  Are you or anyone else running an
MSD ignition product?
