Added Import Cal Function to Files menu. This function will import all the cal values defined in the ECM Definition File from a selected calibration file into the currently open calibration file.
Added support for larger tables.
Increased size of the notes field for type $EE calibration files to 1024 bytes.
Double clicking on a graph will reset the graph to its original size after using the zoom functions.
Bug Fixes:
Corrected a bug that would not enable the Edit menu is when the Constants table is opened.
Corrected a bug that would cause a runtime error 9 (subscript out of range) if more than
10 changes were made to the switch or constants tables.Corrected the routine to read 16 bit MSB/LSB 2's complement values. Previously read values as LSB/MSB.
Corrected a bug to allow the edit step to be less than 0.01. Previously, this was set as the minimum and correspondingly no tables were displayed with more than 2 decimal places of accuracy.
Corrected an error in the print graph function of that would cause a runtime error 10007 after printing a graph.
Corrected a bug that would cause the program to lockup when zooming or rotating the graph and the key is released (Shift or Alt) before mouse button.
Tuner Version 2.00 Updates
Bug Fixes:
Corrected a bug that could cause incorrect min/max limits to be used when entering a constant value in the text box when the file compare function was active.
Corrected a bug that would prevent you from entering in a negative value into a Constant value text box.
Tuner Version 1.99 Updates
Bug Fixes:
Corrected a bug that could cause a programming error when programming the '94/95 LT1 FLASH PCMs. Previously, if you made changes to the calibration and programmed your PCM before saving the calibration file, an incorrect checksum would be programmed into the PCM. This would result in the PCM not operating properly. You can normally recover the PCM by reprogramming it with a calibration file with a valid checksum. If you are using the Tuner program and the $EE ECM Definition File to program your PCM, please update to version 1.99 immediately.

Integrated the $EE PCM FLASH Read and Program functions into the main program.
Added the capability of displaying a full graph for 2 and 3D tables. You can now view the table only, table and graph, or graph only.
Added a chart label to the full graph display which shows the coordinates and value of the data point closest to the cursor on the graph.
Added change indicators to the tables so that edited values are displayed in red.
Added a 'Print All Table to File' function that prints all the tables in a calibration in text format to a text file.
Entries in the ECM menu are now displayed in alphabetical order.
You can now use your own graphic on the main Tuner screen in place of the C.A.T.S. logo.
Selecting a table that is already open from the 'Table' menu will give focus to the selected table and bring the table to the top.
Added support for 2's complement values for constants and tables.
Added a table scalar function.
Added table print in text or graphics mode option.
Added 'Print All to File' function which prints all tables to a text file instead of to the printer.
Added a check so that under the following circumstances, the Program ID test will be ignored:
CheckByte1 = 00
Alt1ChkByt1 = FF
Alt2ChkByt1 = FF
NewChkByt1 = 00
CheckByte2 = 00
Alt1ChkByt2 = FF
Alt2ChkByt2 = FF
NewChkByt2 = 00
Bug Fixes:
Corrected an error that could cause an erroneous 'No response from PCM' error during PCM programming.
Corrected an error that would cause a runtime error 53 when a second compare file was opened and the file compare function was active.
Added code to load the first definition file if no initialization file is found. Previously no definition file was loaded causing a runtime error.
Increased dim of Undo Table and Compare Table arrays to allow table lengths up to 99 (was previously limited to 32).
Arrow keys now work properly when moving around in a table.
Corrected constant min and max limits when in compare mode. This This bug would cause incorrect limits on entered values and could result in a 'Invalid Value Error'.
Corrected error in the restoring of the system printer font in the Print All Tables routine that could cause a program error.
Corrected bug the would cause a runtime error 340 when Preferences is selected from the Options menu when only one definition file is present.
Corrected bug that would cause all switches to be shown as checked in the printout from the Print All selection.
Added test for 8 bit values > 255 and 16 bit values > 65535 to the save table value routine.
Added check for $EE Definition File when checking for .lt1 file type.
Corrected 'Restore Table' function to update the chart. Previously the chart would not be updated.
Corrected error that would cause the graphed points to be reversed from the table points if one or both axes had descending values.
Corrected a bug in the $EE speed calibration tool that would result in incorrect values for the speedometer calibration parameters for manual transmission Corvettes.
You can now open a calibration file with the Program ID set to $AA as a compare file. Previously you would receive an incompatible file error message.
