A lean condition is one in which ignition is actually taking place and there is not enough fuel present. It is not one where there is no fuel present at all. The systems in the Protege do not create a lean condition unless the air where you live has enough combustibles in it to actually ignite from the spark (if there even is one, if I worked for Mazda as an engineer I would have shut off the spark too, no sense wasting power). All your engine is doing is moving air. Air comes in the intake, cools off the cyclinder, and leaves the exhaust. I have had an '83 F-150 for years and I happen to understand the necessity to maintain a proper air fuel ratio. And I happen to have taken enough courses in automotive technology and chemistry to understand the principles of combustion. Please understand someones posts or ask questions before you snap off on tangents.

I think you're missing the point though... the point was, if you are AutoX-ing, and for 3 seconds you have a choice between shifting up to third and back down again or bumping the rev limiter... you're going to be a lot faster if you're bumping the rev limiter.

Sure, if you're accelerating in a straight line, shifting the torque range will lower your time, but if you're choosing "to shift or not to shift" you'll be faster by not shifting.

Running an engine without proper fuel for 1-2 seconds is not good. Running an engine without any fuel at all for 1-2 seconds (I only said 1 second to describe the delay between the fuel being turned off and back on) is fine. Now when you say "proper fuel" if you were referring to the no fuel at all condition I can think of no plausible way that doing that can damage the engine. All that little controlled explosion under your hood is doing is providing force to keep the crankshaft rotating. Allowing the crankshaft to get its turning power from the wheels is not going to hurt anything. As long as that crankshaft keeps turning the drive belt and turning the alternator you will not have any problems.

Hey Jesse, these shift points are for what car and motor?

Just curious.
