Re: Edelbrock EFI info

Well that sucks! The ads lead you to believe that the system is easily tunable by the hand held device. I guess they worked around a lot of electronics requirements by having a "base line" burned into a chip. I bet if you remove the battery you lose the "fine tuning" you put in.

While most systems that are completely programmable are much more expensive, at least one is not. Take a look at www.sdsefi.com (Simple Digital Systems EFI). It's completely programmable from the hand held device that comes with it and doesn't cost a fortune. It isn't a "complete kit" though. You have to supply some parts. To quote the website:

"If your engine is not equipped with EFI hardware such as injectors and a high pressure pump, you will need the following items in addition to one of our systems to convert to EFI:

Fuel injectors
Fuel pressure regulator
Fuel rail
Fuel pump
Fuel return line from regulator to fuel tank
Throttle body

If no suitable EFI manifold is made for your engine, you will have to weld injector bosses to your present manifold, make a fuel rail and mount a throttle position sensor. Details on some of these aspects are available on our Tech Page at: Tech Page/FAQ. Cars equipped with CIS (K Jetronic) mechanical injection, also need extensive modification to convert to EFI, including new injectors."

Still, not a bad deal.
