11/07/03: Version 1.0 – this calibration is based off of v0.6, but now contains the first of the spark curve adjustments.  For starters, I simply used the curves from the 1987 Mopar Performance Turbo II and CSX Stage II calibrations (they are the same).  From this point forward, I will be adding advance to eek out more performance from my CSX motor.  Since I have reduced compression with a head shim, I don’t recommend using any calibrations beyond this point with a stock motor.

11/07/03: Version 0.6 – made a slight adjustment to the partial throttle curve to try to address what seemed like a lean spot.  It seemed to take care of it.  This calibration seems now to get similar gas mileage to the stock calibration.

10/27/03: Version 0.5 – tweaked the cold start tables, AIS tables, and other fuel tables.  The engine starts and idles fine, even when cold.  Decel mixture is good.  Fuel mileage is better than the ND cal was, though still below stock.

10/16/03: Version 0.4 – richened-up the part throttle curve at high boost levels and leaned the no-throttle curve some.  Also adjusted the cold-start enrichment curve down a bit.  The mixture looks pretty good for me.  The only outstanding issue is an idle surge when coming to a stop when the engine is cold.

10/15/03: Version 0.3 – reapplied the v0.2 changes to the real stock 1987 Turbo II calibration and tuned for 55psi of fuel.  I ended up with different curves that seem to be too rich during no-thottle decel and lean at part throttle over 12psi of boost.  Idle mixture is good, as is cruise and WOT.

10/13/03: Version 0.2 – richened up the top end a little, but may be too lean for you, as I forgot that my fuel pressure is 60psi right now.  Gas mileage seems to be good and it gets enough fuel all the way to 18psi or so, even at part throttle.

10/11/03: Version 0.1 – first working cal, actually based on the MP CSX Stage II cal (needs 93 octane).  Has trouble at cold start, as it likes to die a few times unless the throttle is blipped.  Could be a mechanical issue with my motor.
