Re: [DMCForum] Re: Throttle Plates/Manifold Vacuum (Martin Gutkowski)

Bill.

The DeLorean has full throttel enrichment via a microswitch. The CPR 
vacuum enrichment is a curve relative to manifold vacuum. It has nothing 
to do with full throttle other than that it is a point on the curve.

You used the word "advance" when talking about mixture enrichment. Why?

When talking about tehcnical issues, it's very important to use correct 
terminology.
