Collecting some information to check VEMS ECU options
Volvo T6 engine (exact engine code ? number of cylinders) with exhaust cam VVT
Ignition outputs / coils
LS truck coils with built in igniters.
- more exactly ?
- pinout ?
- Active coil (need logic level outputs, or stepper outputs) ?
- or passive coils (need power IGBT output, in that case 8 IGBT would be best) ?
Injectors
- resistance ?
- high-Z (>5.5 Ohm) ?
- 30V flyback is perfect in that case
I'm not sure what options/outputs etc I need. I drive mechanical operated throttlebody and mechanical adjusted boost control and i dont need any knock sensors or idle air controls. Everything else is mostly sure to me, but ...
VVT control doubts me
- VVT solenoid is closely like BMW vanos solenoid. only 1 solenoid with 2wire for camshaft. it controls oil flow to cam gear
- simple low-side (NFET) outputs should be good (using free injector or ignition output)
- Min 2 IGBT would be recommended
