rob@vems.co.uk:
What sort of load are you switching with this system?  How many coils/ inejctors and solenoids?

jadzwin:

4 high Z injectors, two coils (maybe 4 in future with COPs), 3 relays and 1 wideband heater.

I pulled apart a unit last night to see how the grounds come from the factory - the two pins are joined by a wire across to the ground line over by the IGBTs on the underside of the board.  It would be as well to do this as earths are never a bad idea :D

jadzwin:
Thank you very much !!!

I will wire it as you suggest.

So this week I want to run the system on the desk with injectors, coils, 60-2 signal simulator and scope.
I hope I'm able to do it :)
