Bosch Motorsport Ignition Coil 3x2
gox:
Anyone have any clue about pinout?
There are four pins....i need to connect 3 of them to IGBT's,do i need to run them in pairs?
I searched for pinout on the coil but didnt found anything....
tnx
rob@vems.co.uk:
I've never actually had one of those coil packs in my hands, and I've just been searching all over the place to find the info to no avail.
But the way I decode the pins on the coil pack that I have had is to write down the pin numbers then measure the resistance between the pins and writing down the readings.
There will be one common power, and the other 3 will each go to an IGBT - no need to run them in pairs.

Tnx Rob,i will do the measuring and will see ;)

hey I actually know this one!
so for future reference...
pins 1 - 2 - 3 are ground, wire them up with igbts
pin 4 is common +12v feed
pins are placed in logical order: the left pin goes the left coil etc
not so logical is the numbering on the coil spark outputs, ignore them!
use coil 1 with pin 1, and cyl 1+6
use coil 2 with pin 2, and cyl 2+5
use coil 3 with pin 3, and cyl 3+4

This cylinder numbering is correct for Porsche boxer-6 and most V6 engines but not for straight-6 engines.
