Bill has some very valid points.
Dyno testing of a number of Deloreans showed that the ignition system is
not reliable above 5,000 rpm. Clearly, if it starts to misfire at this
rpm, it could use some improvement below this range.
DMCH upgrades the ignition on their 200 HP engine because of this fact.
Second, Dyno testing of turbo and supercharged cars also showed fuel
starvation problems again at higher rpm and engine load.
Many turbo cars, attempt to compensate for this by grounding out the O2
sensor to go to a richer mixture. OThers have used other tricks.
Wiring in the cold start valve may add too much fuel.
However, there is also a D owner who converted to EFI with larger
injectors and got more HP.
Bill start with the Ignition First. You really want to insure you burn
up that extra fuel and don't dilute the oil.
