Tnx
I have Power Resistors and TS diode.Since i`m going to use lowZ on my turbo engine,we will talk about that when the time comes,now i`m using highZ stock on my N/A engine.Just want make sure that i got thinks right and then switch to turbocharged,my wire harness still can stay.
Curently i`m studing your text for Idle stepper (BMW Stock)
Here is what Mattias said to me:
Use a Schottky diode (SR806 is good) to protect the injector FETs if you use those outputs. If you use IGBTs then use the Schottkys anyway because the built-in diode protection clamps at much too high voltage to efficiently control the ICV solenoid flyback current. If you use free stepper chip outputs then you don't need the flyback diodes.
The VEMS Genboard only provides ground. One ground to close the solenoid and another to open the solenoid. The third wire is +12V. It's easy.
What is Schottky didode?
I think you said on some topic here that we cant use stepper outputs for that one?
Tnx
(i know i`m little boring but this is my first project)
