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.)\\ | 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.

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. | The TC88A map table will allow setting the spark timing for MAP conditions from 16 to 30 InHg using 2 InHg increments.

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: | There's a rough correlation of the throttle position to certain areas of the map image.

- | 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. | ||

- | **Remember. Before changes can be utilized they must be UPLOADED from the PC-Link Software to the TC88-A Module. It is a good idea to save the desired changes to the PC Harddrive before UPLOADING them to the TC88-A Module.** | ||

- | If the Fixed RPM Limit box is checked, the FixedLimFlag is set TRUE and only then can you modify the RPM Limit Slider (RLS). The RLS is set to a RPM value as appropriate to your engine configuration (kept low for break-in periods). The slider will adjust from a low of 3000 RPMs to a high setting of 9900 RPMs. The module parameter in the TBL file (RMPLimit) will reflect the value chosen on the RLS. | + | If the Fixed RPM Limit box is checked, the FixedLimFlag is set TRUE and only then can you modify the RPM Limit Slider (RLS).

When FixedLimFlag is TRUE, this selection will DISABLE the __RPM LIMIT DIALS__ on the module since that value is now fixed in the software. | When FixedLimFlag is TRUE, this selection will DISABLE the __RPM LIMIT DIALS__ on the module since that value is now fixed in the software. |
