Can someone explain to me the function of the R3 vacuum lines and where they are located I see them under the tank, I read that I should check them but that's about all,,,,,need help :sad:
 
There is one vacuum line from each throttle body which goes to the MAP sensor ,it measures pressure or vacuum ,and changes the reading to volts so the ECU can see what is going on in there

Further to this, the MAP values are used in the 'L' tables.. Tuneboy ( & Tune ECU) have F & L fuelling tables. F is used on throttle & L for low throttle & off throttle fuelling. You can set the % throttle opening where these tables crossover.
Mostly L tables would be adjusted to eliminate popping on overrun after fitting more open pipes.
The lines themselves shouldn't be problematical, just make sure they're not twisted up or loosely connected.

I checked all lines , no kinks, tight on the fittings, I am using your tune modified by Hanso ( I think) :grin: still a stumble on idle, haven't tried it yet on the road,, darn weather won't cooperate :roll:
 
Quispamsis, Beck, really? What the hell is a Quispamsis?

:smile: Quis- pam-sis, is a local Mi'kmaq Indian word ( pronounced "Mic Ma") which means " Little Lake in the woods" our town is centered around a lake we call Ritchie Lake. apparently this is the little lake in the woods :lol:I hope this helps :p
 
OK, that makes sense to someone who lives in an area with Tahuya, Hamma Hamma, Queets and Humptulips. (Not sure what that's the Indian word for.)

We now return you to your regularly scheduled programming.
