Simon,
Sounds good to me - anything to get control all in one unit, instead of half
mechanical and half electronic as my '89 Audi 200 is right now. And be
able to data-log, and see & tune from a map of settings.
I'm a good mechanical and plumbing guy, have a decent shop, can TIG weld and
silver solder, etc., and can do good wiring, but as far as EFI theory goes,
I'm a no more than a parts changer so far.
If you know how to make or design the fuel rate module, I'm in for the parts
that I can contribute.
Let's me know what's involved, this sounds pretty good.
Ernie
