If it is a Haltech, most systems give you the ability to connect a laptop and upload from the Haltech EMC the current tune. That current tune is likely what roger is calling the secret sauce.

I highly doubt he has custom software in a factory Haltech EMC.

This is simple to figure out.

1. Find the model of Haltech EMC.
2. Download the software for that model.
3. Load software on laptop.
4. Connect laptop to Haltech EMC.
5. Upload current EMC mapping (ie:"the secret sauce")

For someone to tell you it is custom and to leave it alone is, IMO, stupid. You should know how everything in your car works. There is NO MAGIC in there. Sounds like Roger has been less than helpful and continues to be that way. Sorry for friends of Roger but he is not someone I would have wanted to buy a car from.

Not to worry, it is no magic. Haltech EMC's have been around a long time and are typically very easy to work with.

To Doug's point, you NEED to save the tune so that if anything goes wrong with the EMC in the future, you can get another one and reload the tune and then you are back on the road, with the same tune!
