Hi everybody,
I'm driving my Golf 4 (1.8T 20v)allday long with my 3.7 installed and it work fine...
But for more reliability I would like to change my old style 3 wires COP for the more recent (115r)with 4 wires (5 Volts trigger).
After some some test on the bench I find that I need +5v to trigger it .
My idea is to use a LM7805 to get stable 5v without worrying about the input.
Why?
because the voltage is never the same and if I use simple resistor, the output will follow these fluctuations.
My questions is :
Can I use this regulator in serial with the direct output of the igbt/logic driver or it would be better to work with stepper driver?
I think yes for both of solutions, but your advice will be very helpfull to confirm
Thanks guys
