What is E.E.C. ?

[YENKO DEUCE REGISTRY]

Good explanation Rick, that was my understanding as well. I think the Deuces don't get the full advance until 4th, ie; the TCS is fully turned off when the engine is at operating temp and the trans is in 4th gear.

Per Jacks chart,that would give it the characteristics of a TRUCK transmission,would it not?I'm curious if this is actually the case,and if the Deuce's 4spd.trans. applies vacuum in 4th gear only.
Please let us know your findings.

I guess I could simply start the car, get it warmed up, put the trans in each gear and simply wait till I hear the rpm's rise?

When I start my car cold the fast idle is on you can hear when the temp switch cuts the vacuum it will drop 2-3 hundred RPM's.
Then when warm and idling putting the shifter in third will drastically raise the RPM 4th gear also.
Very easy to test to see if these systems are working correctly, and not bad to trouble shoot. I think at high levels of judging this should be included in tech inspection, if yours works you should get credit for it.

Good point.

Ditto that!
