Re: [DML] Cold start valve wired to full throttle switch (don't bother)



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.
