2nd fill

I really should rename it to Fuel Sucking Pig...

My 2nd measured fill was only marginally better than the first: 56.6 MPG US vs. 56 last time.

Part of the problem I realized is the MPG instrumenation has been somewhat screwed up (reading high) from keying-off to kill the engine. Thus affecting the feedback loop to my brain, hands & feet.

Motivated me to add a warm air intake (simple aluminum dryer ducting between the intake and exhaust manifold area).


Plus, the latest mod installed just yesterday is a proper shifter-mounted kill switch (via Crank Position Sensor interrupt). It might be the first Mirage with this particular mod over on the Mirage forum, so I shared a bit of a how-to...
