Emergency with MembersPage/RagnarBurenius
Resolved. MembersPage/KeithHargrove, from Milpitas,CA, USA West Coast prepared an old v3.0 ECU (changed to primarytrigger VR) and handed over.
However, it came to Keith after he sent out that
- the v3.0 has nonstandard FETDRIVER_NONINVERTING setup... This was a self-assembled board as this wasn't used too much. Not possible to make it work just by configuration (it would activate the injectors right after powerup!). A firmware compiled with -D FETDRIVER_NONINVERTING needed: http://cell.dyndns.ws/vems/firmware/v3_firmware_1.0.44_NONINV.zip (1.0.44 has no major configuration/comm changes since 1.0.36 GenBoard/UnderDevelopment/FirmwareChanges so MegaTune won't be a problem).
- see MembersPage/KeithHargrove for the IGBT positions (also nonstandard). This is easy to handle with econoseal pins and "ignition sequence" configuration, see GenBoard/Manual/DigitalOut and GenBoard/Manual/DigitalOut/Table for pin mapping. MembersPage/PeterJensenwiring suggests that on Keith's picture 0,1,5,6 ignition channels (Keith confirmed these) have IGBT's. mdh82, mdh92, mdhd2, mdhe2 commands will verify (might only lit for short flash since ign-code disables them soon if ignition sequence is configured)
- cathode- to output
- anode+ through 270..4700 Ohm pullup (series with the LED) resistor to +5..+15V
- take care of polarity when installing the GenBoard/Manual/PowerFlyback powerflyback board. The cathode (marked with a line) connects to the injector+
Note that they took another ECU, a v3.2 in case something bad happens. The v3.2 has normal inverting FETDRIVERs. The power ignition outputs are same (nonstandard) as the v3.0 : 0,1,5,6
Communications to handle the situation:
- write here, on this page
- I made a #v3needed for this emergency situation irc channel on the same (efnet) where our #avrboard channel is hosted: see ChatViaIrc
- from the onsite team contact: phone: +46709557097 Ragnar Bolemius (Swedish guy, in the USA now, this is his cellphone)

Setup:
- 250kPa MAP sensor is fine
- non-demanding 4 cyl wasted spark app,
- primary trigger VR
- secondary trigger: don't care
Even unassembled genboardv3.x would work as last chance
- + with Econoseal connectors (EC18PCB + EC36PCB)
- + FETs (min 6, preferrably 10)
- + IGBTs (min 2, preferrably some spare too)
- + 250 kPa MAP sensor
- + powerflyback -
- the rest
- + Alubos - would be nice
- + 3 clamping plates and 3*10 mm screws would be nice
- + frontplate optional
- - endplate truly optional
- - stepper chip not needed
The ECU prepared in HU WebShop (that just missed the last Fedex plane that could have took there in time) was sent to MembersPage/KeithHargrove.
