[Diy_efi] Override/Passthrough EFI system?

[Mike Gruber]

I'm working on one for my '88 Supercharged MR2.  The basic hardware is 
in place.  See <http://www.grubinski.com/grubinski/dataacq.project>.

The next step for me is to use the system for data acquisition, to 
figure out what needs to be changed fuel and ignition wise, and how 
much.  The second step is to actually take over the injectors and 
ignition.  In my case, that will probably mean richening the mixture 
below 3500 rpm by stretching the injector pulses, and leaning it out at 
the top end.  But I won't know for sure until I get some data.  Thank 
you DIY_O2!
