How to controll alternator on an NB with EMS
I am looking at getting an EMS4 since I cna get a great deal on it. The only thing that I dont know about is setting up the EMS to controll the alternator.
What are you all doing to get the EMS or EMS 4 to run the alternator?
Please remember I this will be going into a NB.
Have a great day,
Jared

Most people that have DIYed their Megasquirts use a circuit designed by JasonC SBB. My own Megasquirts have a digital control circuit that does the same thing, with some additional features like a smart battery light.

I installed a 1.8 na alternator this last weekend when I installed my EMS 4. A PNP harness was made. Only what I needed to run the EMS is connected. Will I still haev to cut the wire? I am having some power feedback issues.
Have a great day,

alternator control
Has anyone gotten their ems4 and left the stock ecu in with connections to the alternator? I tried but I have a battery light and it only seems to charge very slowly while the car is parked...maybe because the factory ecu can't see engine speed anymore..
I know adaptronic did this so I know it's possible.

We've done it using a schottky diode (similar to the circuit Adaptronic uses) but in all honesty it's cake to just use the NA alternator.
