Hello All,
In support of our new Engine simulator project (TMES aka Turbo-Mopar Engine Simulator pronounced like the River Thames "pronounced 'tems', with a simple 't' sound"

I have been working to better understand the REF and SNYC HEP signals, I used a real turbo distributor from my Shelby Z and tested various HEPs that I have. It appears that all my HEP are not the same but you knew that right?. I tested two Mopars and aftermarket from my CSX they are consistent from a "first look". Interesting, one from my Shelby Z the angle between the Sync and REF. is different but the car did run well. I am unsure how bad it must be to stop working. If you have a bad one for me to test LMK.
Here are my tests from my Saleae logic analyzer. The angle between the REF and Sync ranges from 166 to 168 degrees.
