I just intalled a NEW sm4 into my calais if anyone needs a cad file using 750cc injectors,gt35/40r.My problem is I'm running a standard coil and canot get spark.The sm4 wiring diagram does not tell me how to wire single coil.I have tried the O/P ignition 1 (pink/white)running to the power trans then back to the Neg side of coil then to +ign with no luck.Any help would be GR8. Some original photos have not been recovered yet.

Try a search on the "Autronic MRM Forum". might help

did you get the crank angle disc the autronic supply for vls too?

yeah ill be like Coran using a chopper disk in the distributor. Is this reliable and work okay as apposed to a crankt trigger sensor? or does the sm4 require both? Im struggling to find out also how to wire up the single coil for the sm4 as the power im chasing will not be needing an ignition box. any help would be great cheers

Good news guys,Drove my calais back today from SAS. Problems they found were- Cranck and Sync inputs to ecu repaired intermitant signal. refitted diodes Rewire CAS with battery voltage supply instead of 8v Replaced week ignitor. It starts and drives fine now Thanks to the boys at SAS Some original photos have not been recovered yet.
