Hello all!

Anyone here with expirience with MR3 Marelli Competition ECU? A friend of mine brought his unit to me, it does not produce spark anymore. The loom is also here. The racing season starts this weekend for him (what a timing ), so it is urgent.

The basics have been checked, sensors are ok, TPS and MAP are getting 5v supply, there is 12v at coils.

The following would be of help to me:
1) Wiring diagram
2) Software for mapping / diagnosting MR3 ECU
3) Person with hands-on expirience with this unit

Many thanks,
Nikola
