Update Logs
09/04/1999 Updated the L9112D Interface schematics to reflect the A/C input to the ECU.
Updated the PN 3516 Source Code with more constant and table definitions.  Also added the option to down load it in ZIP'd package rather than just HTML.
Updated the Mistake Log. mis49 was not as broken as I had originally though.  Some of the code stilled worked.  It compensated for air compression at elevated altitudes.  Also I have had second thoughts about mis22.
Under the Miscellaneous General Programing Errors I added some comments concerning the altitude correction code (L0008) under mis49: and a little under mis22:
10/03/1999 Updated the Mistake Log. mis73 added to the log.  Found this one while doing the flow-charts.  During code restarts the intended MPU register is not been updated because they forgot to set the IY register to the 68HC11's register base address.
10/25/1999 Completed most of the flow-charts.  The main routines and interrupt handlers of interest are done.  Some of the less interesting and more mundane stuff may follow if I get really ambitious at some future date.
10/31/1999 Started to do work on the In Car Programing.  While I was at it I also determined the remaining PAL Input ($6000) and Output ($4000) latch bit definitions.  WEB documents have been updated.  It looks like the PAL is well behaved as far as the R/-W functions are concerned.  Looks to be no hidden gotch-ya in it that would make adding an EEPROM more difficult than it has to be.
11/28/1999 Got the In Car Programing finished.  The schematics are now on line.  Photos yet to come....
12/xx/1999 The Ignition Trigger / Jitter page is constantly changing as I am currently work on this are of the car.
12/21/1999  Updated the HY1 ECM schematic to reflect the addition filter of the TPS input.
01/02/2000  More work on the Ignition Trigger / Jitter page and also a new page on the Shutter Wheel.
01/13/2000  Add some construction photos of the Crank Trigger installation, the Distributor CAM position shutter wheel, the ECM daughter board for in car programing, and a little more detail on the SA - Ignition Trigger handlers.
03/01/2000 Started the Throttle Transient Response page.
10/10/2001 Well after just 12,000 miles the supposedly heavy duty Mallory fuel pump FAILED !
07/24/2002 Installed a Surge Tank so I could around right hand turns.....
03/24/2004 Installed new Stainless Steel Fuel Tank.  Removed old Surge Tank.
01/20/2005 Installing New MPC555 Based ECM.  Completely replacing the original Weber ECM with a high performance ECM based on the Motorola PowerPC MPC555.
