Tom,
I have the wolf ECM to control the fuel and the timing. I have not used it as yet. I do have EFI on my cobra with a control module
and I love it. Being able to fine tune your system for weather, racing or economy is the best. There is a learning curve involved but it's worth it and not that difficult.
Wayne Presley who is a member on this board is now the North
American distributor for the fuel system that I have. Talk to him and see if he can set you up.
