Trigger definition

So , I came across a crankshaft reluctor wheel with the following patter hall sensor btw, 17-2,16-3 im using EcuMaster Emu Black how can this reluctor be decoded? First time I come across this type of reluctor wheel

thanks

I'd email ECU Master and ask but it's unlikely they would support this. The easiest option is likely to be to fit a generic trigger wheel that's supported such as a 60-2 or similar. You do need to be a little wary though as some unusual trigger patterns are included for engines that use variable cam control or similar.
