1989 Turbo2 Mopar Performance based SMEC calibration

The Ladybug system, in combination with ChEM or D-Cal, is your ticket to custom
calibrations and modifications for your 88-89 2.2 or 2.5 Chrysler turbo car.

Unzip into a directory and double click "Ladybug.bat" to build the binary image
from the ASM file. You can edit the ASM file (assuming you have some knowledge
of 68HC11 assembly) to add or change functionality. An extremely large
percentage of the code has been decoded and explained by using intelligent
names for variables, bits, and tables, and some explanatory text is scattered
where it will be useful to a tuner.

Also, near the beginning of the file are some variables that you can change
which will cause changes throughout the code, and even rebuild the cal for
either a 2-bar or 3-bar MAP sensor.

Mods included in this version:

* CE Light Detonation Indication: lights up the Check Engine or Power Loss
  light if any detonation is detected while running. Extremely useful for
  high boost engines and to ensure that your advance hasn't been overdone.

* Staging Mod: keeps engine RPMs at your ideal launch point when stopped,
  so all you have to do is drop the clutch and GO. Once moving, this mod
  disables so your rev limiter is back to 6650 RPM.

* 3-Bar MAP sensor: Although the fuel injector mod isn't complete yet, this
  allows you to run as stock using a 3-bar map sensor. All known uses of
  the MAP sensor have been accounted for.

After assembling the image, a TBL file is automatically created so you can
quickly make changes using ChEM or D-Cal. After modifying table data, you can
integrate your changes into your ASM source file by copying the bytes seen
using the "View Tabular" option.

Before burning the BIN file onto a chip or flashing your modified SMEC,
double click "MakeChecksum.bat" to have the checksum calculated and the image
modified (using a fixup byte at 0xff50) so you don't get a Code 53 error.

NOTICE:

Messing with the cal without understanding what you are doing CAN BE BAD. It
would be simple to overdo the advance or underfuel the engine, resulting in
detonation, or even catastrophic damage to the engine. Be aware that this is
NOT a fully automated solution, and nothing will replace experience and
knowledge in gaining more power from an engine.

Your use of this calibration and documentation is YOUR CHOICE. By using this
system you agree to take personal responsibility for its use, and NOBODY ELSE
IS RESPONSIBLE, EVEN IF FAULTY INFORMATION IS GIVEN. It is up to YOU to
determine if this or any modification software is appropriate for your use.
