cis 3 ecu intereaction

[Alan Pritchard]

also, I meant to say... on the diagram I have there are 3 wires
interlinking.....on the fuel computer they are labelled as.....1,21 and 30,
and on the ignition ecu: 5,8 and 17. 5+17 seem to send to the fuel computer,
and 8 receives. So the tach input goes into the ignition computer first I
guess then to the fuel computer via 5 or 17, another line must be for error
codes I guess, sent to the fuel computer..... am I getting close?? Where
does the tach feed to the instrument cluster come from? Is that the fuel or
ignition computer? And will I be able to use the tach signal from the
ignition computer for ms? Or would it be simpler to come of the coil?
Thanks again

Hi guys, further to my wiring diagram request from the other day, I am
looking for a bit of further information. As I am replacing my fuel computer
with ms, I am trying to do a load of groundwork, what, if any, interaction
goes on between the fuel computer, and ignition computer. I presume there is
a tach signal between the two, anything else?
