1987 2.2L Turbo II for 3bar MAP and 52pph Injectors


DESCRIPTION
-----------

This calibration is based on the stock 1987 2.2L Turbo II calibration.  It has been
calibrated for use with the 3 bar MAP sensor and the 52pph (+40%) fuel
injectors.


INITIAL CHANGES
---------------
3 Bar MAP:
- All MAP scales "Quick Set" to -14.7 - 29.4psi.
- All MAP values scaled by 66.666%.

52pph Injectors:
- PumpingEfficiency scaled by 63.46%
- FuelBatteryOffset scaled by 63.46%
- FuelBaselineFomMap scaled by 63.46%, last data point tweaked.


NOTES
-----
FuelBaselineFromMap: enrichened, last data point not scaled by 66.666%
AisOffIdlePositionCold: first data point pulled way down to prevent idle surge
FuelColdEnrichmentCurveA: heavily modifed for consistant startup and lean decel
FuelNoThrottle: leaned slightly in heavy vacuum
FuelPartThottle: heavily tweaked to enrich high boost mixture to prevent breakup


CHANGE LOG
----------
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.

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.

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.

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 10psi of boost.  Idle mixture is good, as is cruise and WOT.

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.

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.
