So this is the section i'll put all my previous issues up on. i'll edit the format as time goes by to make it easier and organized.

Just add the answers or any help below each problem. Add any questions at the bottem like always!


my first problem i ran into while I built my first VEMS system (which then i sold before start up) I couldent find out how to wire up the stock E30 tach up. 12V pull up wiring, grounding via tach output pin.
How abouts to i get an electric fan set up? i will be trashing the fan on the end of the waterpump for something a little more conventional. Not really a problem. Ground the fan relay using a free output.

Questions for me:
