GenBoard/Manual/IgnitionOutput

Standard genboard ignition outputs

These show you ignition (i259) channel assignments to EC36-xx pins:

Depending on webshop options you've chosen during ordering, some of the 8 are high power outputs, the rest are logic-level.

It is easy to measure which are logic-level outputs, because logic-level output pulls toward GND5 when inactive. Measure DC voltage on output, with your DVM (20V mode), with +12V (or +5V) being the base.

If DVM shows -12V, than either

New standard - power and logic level ignition outputs since 2006-12

IGBTs Nickname power outputs Logic level outputs
0 0 - 0,1,2,3,4,5,6,7
2 2+6 2,3 0,1,4,5,6,7
4 4+4 2,3,6,7 0,1,4,5
6 6+2 0,1,2,3,6,7 4,5
8 8 0,1,2,3,4,5,6,7 -

Option 0 All 8 injection channels have logic level(+5v) control for coils that have built in igniters or systems where you wish to use an existing Igniter pack:

Option 2+6 Two channels are high current, the other 6 are logic level:

Option 4+4 Four channels are high current, the other 4 are logic level:

Option 6+2 Six channels are high current, the other 2 are logic level:

Option 8 All 8 channels are high current control channels:

Assembling when purchased from WebShop unassembled

The 0,2 and 8 IGBT-s are trivial. (the 2 IGBTs are for ignchannel 2 and 3, so only 2 clamping plates are needed in this case: the 3d line of switches has no IGBTs).

The L means logic-level (short between output and gate). The numbers are ignition channel numbers for the given physical position. EC36 is at the bottom

OLD standard - before 2006-12

The 0,2 and 8 IGBT-s were always the same.

The new scheme is more useful with the (rarely used) "ign dualout" option.

The 4 (4+4) and 6 (6+2) options were different before 2006-12 :

Option 4+4 Four high current channels, Four logic level:

Option4+4.png

Option 6+2 Six high current channels, two logic level:

Option6+2.png

Actually, controllers with 6+2 config sent out before 2005-09-02 had channel2=EC36pin34 and channel5=EC36pin12 configured as logiclevel. If in doubt, measure.
