Hey guys.  This question is for you propane guys.  Do I still need the ECM if I have a propane carb installed?  The propane carb does not have all the dang wires like the factory carb does.  If I don't need it, great.  If I do need it, how do you hook it up?  Thanks for any help.

No.  The Samurai ECU is no longer used.  A new aftermarket carburetor (Propane or otherwise) is not designed specifically to work with the Samurai ECU.

You will need to plug up any unused vacuum ports on the intake manifold.

Thanks.  That's what I was thinking.
