Another option for the controller is something I was introduced to when I was researching the parts I need to build the monster VW engine I want to put in my toy (Yes, I know "monster VW engine" sounds wrong, but we're talking a 3.5L turbo 4-banger that can turn 350+HP at the wheels).
It's by a company called Simple Digital Systems , thier basic system has everything you need short of the MAF & injectors, can run anything from a 1 cylender to 8, and is fully programible with a simple module that is part of the package (no computer needed). It's also designed to work with turbo setups if people wanna get silly like that. Pretty well rounded system for the coin.
Just a thought anyway. smile

I dig all cars, old and new, whether they were hammered out of American iron, German steel, or Japanese tin cans. Being unable to appreciate them all is missing out on a world of great things.
But thats just MY opinion! :P
