I've bought an old VEMS (V3.3 - V3/531) which I'm upgrading.
Thematically organized, editable page (like this) is required for support (otherwise optional).
- [external] (non-editable)
I would like to buy all the parts needed to do a (almost) max (??) upgrade.
- 2xWBO
- 2xEGT
- AD597
- have full 8 IGBT
- and have as many analog inputs as possible
- does NOT usually require any special parts (perhaps some resistors like 2k7 for pullup to +5V)
- of course all this is far from "max", since VEMS can control 4 camshafts + 2 CAN-buses, DBW / electronic throttle(s), ...
I havent decided whether its going on a BMW M42 engine, or a S38 yet. Both of those are VR/VR though, so i need a secondary VR chip (LM1815)
- So far from the forum ive found im missing R103 and R3
- use order comment for a list of resistor values, like:
- 0805 : 5x 2k7 2x 10k
- throughole: ...
- add a few (eg +2) extra each, these are cheap like 1 EUR / item (handling, the parts are almost free)
I also dont know if i need a stepper driver? It is missing on my board
- if you need, you can install. Most engines don't need stepper outputs.
- For NA engines ( 20-103 kPa), any MAP sensor is suitable.
- Use wires to connect the second WBO2 (through some connector, like SSC5 female).
- See GenBoard/VerThree/Schematic
- pump- and +12V are shared between 1st and 2nd WBO2 (pump+ nernst, heater are separate)
List
- [AD597]
- [LM1815]
- [27k resistors] for LSU4.9 nernst pullup to +5V
- For LSU4.9 i need 2x27Kohm resistors.
- [30V bidir or unidir] 1k5E30 transient protection diode
- parts to do a proper flyback.
- or [8 channel active flyback]
- [stepper driver] optional
- [IGBT]
- ... continue
