MSD Can-bus Data

Has anyone figured out how to get the data from the Grid into a non-Racepak datalogger? I'm thinking of going to the Grid and would love to get the Can-bus from it talking to the Can-bus in the AEM logger. AEM is looking into it for me but thought I'd do some digging on my own as well.

I wonder if the can-bus works on the same specifications as regular OEM can-bus stuff? Seems like a lot of data going across those lines.

I believe it is standard can-bus 2.0.

In order to read the Grid, the programmer would need detailed information from MSD regarding the instructions and data format. Since MSD owns Racepak, that information will probably not be released to competitors. Unless that is made available, you will need to download the Grid seperately. What information do you want from the Grid that is not available on your data logger?

I'd like to overlay my retard curves and other ignition info. The rest of the data would be redundant.

You can read the actual ignition timing with a tach timing module from Electrimotion.com. The timing line from the grid shows what it was supposed to be. (If everything is ok, they will be the same) The module will output an analog signal that can be read into your data logger.

Thanks for the tip. Sounds like what I need. I appreciate the help.
