AChartPro(tm) Release 2 with Programming, Data Logging, Auto Analysis, 

Calculations, Gauge Panels and more ! 

AChartPro(tm) collects vehicle performance data from Holley® Pro-Jection® 4D and 4Di engine management systems and allows the user to chart (graph) and program all 4Di variables as well as display both static and variable data in real time. Collected data can be saved for review and analysis at a later time which is useful in determining the effects of your programming changes.

Note: AChartPro Programming module requires ECU EPROM version 3.24 or later.  If you do not have a version 3.24 or later EPROM, contact your Holley distributor to order the current (Version 3.32) EPROM.

If you are not sure of the EPROM version that you have, you can download a program here that will check the version for you.

Auto Analysis will analyze your saved data file and compare it to your ECU's fuel map and recommend changes to your ECU's program (.216 or .316) file to improve system efficiency and performance.  Using this new feature you should be able to tune your fuel injection system in a very short period of time.

The calculations module will assist you with throttle body and injector sizing.  Remember, bigger isn't always better when sizing your throttle body and injectors and oversized throttle bodies and injectors will make tuning your system very difficult, if not impossible.
