 In addition to the pre-programmed timing maps (selectable by the dials), the unit can be user-programmed to utilize customized timing advance maps instead of the pre-programmed maps. To use these customized maps, you must have a computer interface, such as the Daytona USB Interface (18014), and the Daytona PC-Link Software, to communicate with the TC88A module. (See the extra links below.)\\

 The TC88A map table will allow setting the spark timing for MAP conditions from 16 to 30 InHg using 2 InHg increments. Note that 30 InHg manifold pressure represents wide open throttle (WOT) and 16 InHg represents deceleration or idle conditions.

 There's a rough correlation of the throttle position to certain areas of the map image. Also remember that the CV carb responds to throttle changes with changes in the slide (which is a variable venturi) - It is the combination of the two that creates the change in pressure. The general relationship is illustrated below:

-Note that the module makes some modifications to the uploaded and stored timing data (perhaps due to interpolation for MAP values). This fact suggests that one might want to have a base TBL file that is modified as needed and used for a direct upload to the module (rather than downloading a previously uploaded file, which was changed by the module, then making your intended modifications to it and re-uploading it). Perhaps trying both methods will produce the desired results.
+Below is the 3D Map that the TC88A PC-Link Software produces for the 'Jester Delta' table data. Please note that this type image view (because it is an angled view of 3D information) distorts the advance values at higher MAP levels (near 30 InHg). The image makes those advance values appear less than their actual values. So refer to the table data for a more accurate perception of the programmed advance value at the higher MAP levels.

 The module parameters (which are saved in the map TBL file) can be altered in the PC-Link software under OPTIONS. Be sure to carefully set these parameters BEFORE UPLOADING your customized map to the module and before saving your map for future use. AFTER the TBL information is uploaded to the module, these settings will be effective on the module.
