Collecting some information to check VEMS ECU options
Volvo T6 engine (B6284T inline6 cyl) 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) ?
- yes LS7-9 coils are known good CNP coils with strengthy spark, logic level to control them
- or passive coils (need power IGBT output, in that case 8 IGBT would be best) ? NO, not passive
- Active coil (need logic level outputs, or stepper outputs) ?
https://www.jfetech.nl/epages/080402.sf/en_GB/?ObjectPath=/Shops/080402/Products/LS2-Coil i mean these coils. how i can find out that is it needed a stepper or logic level output from ecu? if i understand right these are active type coils.
Injectors
- resistance ?
- high-Z (>5.5 Ohm) ?
- 30V flyback is perfect in that case
i use high-Z injectors. around 9-11ohm
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
ECU VEMS V3 (v3/20423)
- MAP connection: 400kPa (6/4mm pneumatic) (so 180C PTFE tube can be used directly)
- primary_trigger: HALL
- secondary_trigger: HALL
- ignition driver: 2 IGBT
- additional Low-side NFET outputs: 0 (not needed)
- NOT needed, if 2 IGBT (or free injector outputs)
- Knock input channels: 0
- Flyback: 30V (not LowZ active flyback 8ch)
- EGT input:
- Hi-side PFET outputs: 0
- ETC BridgeOutput_Interface: 0
- withSDcard: removable
- LCD connection: no
Please carefully examine all options, including Flyback: 30V, manufactured as noted.
