Megasquirt EFI Lean Cruise Reality Check

GREAT!! Sound like you have made some good progress "I ain't a tuner" either LOL

My progression/ experiments into EFI:

1...Found an old Holley "Pro-jection" system, one of the old ones with 4 or 5 pot adjustments on the box. These are not programmable, they are pot adjusted, 2BBL TBI. Did not even originally have an O2. They are operated in what is called "Alpha N"

2...Found a used complete Holley "Commander 950, a 4bbl TBI unit with an "all manual" but very capable computer---this was the earlier Holley system, adaptable from TBI to multiport, and could run either Alpha-N or Speed density (MAP sensor)

3...I got a third party program for the above from some guy which "autotunes" the fuel map and that helped but in the end I.........

4.....Bought a bare bones Holley HP computer and harness and used the Commander TB with the HP computer. The HP is in most of Holley's higher end stuff except Dominator which is a different computer. The HP also, can be operated either TBI or multiport, and either Alpha-N or Speed Density

This was all at the "end" of the Dart (which is still apart) and "projections" were to adapt it to multiport or even a Hilborn manifold which I scored
