Hi all, silly ideas day...
Now I know the Camira module is intended for use with a reluctor pickup, but looking at the diagram posted here:
http://pcmhacking.net/forums/viewtopic. ... rt=10#p931
It looks like a 5V square wave signal could be simply connected to the reference signal of the module/ECU? This way it would only use the amp/ignitor and EST bypass relay in the module, I can't see any reason why it would need the VR input?
As far as I can see the hall effect sensor should work fine with 5V (thinking using a small IC regulator for clean output) rather than 12V? Is there an issue with teeing the hall effect output with the ECU ref signal?
It all seems a bit too simple, I must be missing something? Can't find enough plugs to try it out without chopping up a perfectly good loom on a running vehicle just now.
Camira module with hall effect trigger?

Re: Camira module with hall effect trigger?
I think you would be fighting the output of the AC to DC signal converter in that picture. Your effectively trying to inject a signal in to an output. Can always try it, but def add some sort of logic buffer on the output of your hall sensor or you may damage it.
Re: Camira module with hall effect trigger?
Good point, I was just assuming that without an input the output would be low/zero. Will have to get around to testing it at some stage
