Direct Ignition with G3 LEM - can't get 3&4 to fire?

I've just rewired my Eunos to use toyota COP's, changed settings to direct ignition, all 4 ignition channels are set to ignition, put appropriate dwell times in. Turned the key and it started, but only running on 1&2. Used the ignition test function and 1&2 fire fine, no life from 3&4. I checked wiring for continuity ecu plug to COP plug and all fine, checked ground and power all fine. I'm a bit stumped, it appears to be a software problem as it appears although the ecu should be firing channels 3&4 it isn't. Any suggestions? cheers Steve B

I've had it suggested that the OEM Mk1 MX5 cam angle sensor triggering system is in-sufficient and I'd need a crank trigger wheel to sort this out? I notice in the G3 trigger setup page it also lists MX5 OB2, is this the mk2 setup that has an OEM trigger wheel? If so, if I bolt on the setup from the mk2 will this work?
