One of my customers sent me a photo of a hot start relay he had plugged into his DeLorean. I had him send it to me with his core return so I could test it. It turns out this is a VW hot start relay. So my thought that DeLorean designers put in the hot start relay socket as an after thought was probably wrong.
The VW hot start relay (pn 813 906 064) delays firing the CSV for 1.5 seconds. It then fires the CSV for 250 ms., off for 720 ms., then repeats as long as it stays powered. So maybe the VW CSV was a higher flow rate then used in our DeLorean engines. Not sure if those short CSV pulses would be enough to help the DeLorean engine start.
