No, what i'm talking about is actually killing ignition and injectors on 4 cylinders and using them as air pumps to cool the motor if the vehicle is overheating, not breakage.

 

My truck has a valet program where 4 cylinders drop out above 30mph, and the boost bypass remains open.

Basically it becomes n/a f-150 that can't go far above 30mph before it falls on it's face. I do this anytime i have to leave the truck somewhere that I don't trust 100%.

It is possible, just not all tuners have the skills to do it.

#1- NO ONE parks me L but me

#2 if you got a parking lot attendant driving your L over 30MPH while trying to squeeeeeeeeze it into a parking spot, you need a fking baseball bat not an anti-a$$hole program

I have to totally agree that foot control is 100% the bottom line here.
My L using the 550+ HP winter program CLEARLY gets MUCH BETTER gas mileage than my V-6 Mitu-whateverthefkitis "on the street". It cost me a minimum of 10.00 (sometimes 15.00) dollars a day to drive the Mitsu on my normal daily routine. I can prob double that with the L on the identical route.

WHY ??? cause my foot is to the floor board 24/7 when driving a v-6, that POS has "no *****" at all (03 Diamante with ever option known to man kind)
Where as the L is so frigging powerful these days you literly dont even push the pedal anymore and you actual drive faster. However if I'm out playing it is a totally diff situation of course, and then will revert back to a timer and not a guage, hehehehehe

Now on the parkway thats a horse of a differant name, I documented 33 MPG on the way to Lake George and back this yr with the mitsu. Where as the L will document 9 - 11 MPG on the street, and not much more on the parkway.
I do need to check it again with this motor, I'm def getting way better MPG ?
The L takes 3/4 of a tank everytime to get to V's and then English Town. 1/2 tank the first 100 miles to V's evertime, and then a 1/4 tank the other 30-40 minute ride to the track from his house. I always figure 10MPG, and put @ 13 gallons in an empty tank (3/4 on the guage) I get to the track with maybe an 1/8th tank every time, then put 40-50 of race fuel in it.

Bottom line I would look for things like an electric clutch to cut off the Supercharger, have it go into (and stay) in OD at lower MPH, and lock up the converter immediately at the 2nd to 3rd gear shift. That with the proper timing "and a light foot" would prob increase the MPG 50% ???

 

thanks

 

Sometimes a place doing an alignment or the dealership doing cosmetic warranty work has to test drive a vehicle afterwards. In that case i think giving them 30mph is decent.

I also go to places that aren't strip malls. Lots of nice restaurants in downtown miami and southbeach don't have parking anywhere near them, but rather go into a garage down the street.

It's a matter of last resort only, I usually am the only one who will park the L, unless I really have no choice.

 

I hear you
and I wish I had that program, 2 yrs ago when mine got inspected
I told the dude 1 thousand times DO NOT drive my Truck,
I go to pick it up at the end of the day and he says,
WOW MAN THAT THING IS FAST AND THE TRANNY HAS QUITE A KICK
*(#%$(@#%(@$@($%

I'm due real soon for this years inspection and it surly isnt going back to him..

 

That's 16mpg...and not impossible on the highway. The last time I calculated my mileage on a road trip I got 15.94mpg. That was with conservative driving and practically all highway @70-75!

 

LET me know if you will what they do say? Are you saying they can't kill the fuel and spark to say 2-4 cylinders when in closed loop mode?

 

I'm pretty sure they said they couldn't do the cylinder drop out,don't quote my on that though, but I'll talk to Jim when I go back in February for an updated dyno tune.

 

Its not that easy! I've read the technical requirements to make such a system work and it is very complex. If it was that easy, all manufacturers would do it to all their engines. DC, GM and Honda have only a few applications. We will see more in the future no doubt as new engines are developed.

Don't even think that a backyard tinkerer (certainly without a basic engineering degree) can make such a system work properly...

Thanks that is more what I was looking for. Time for the next thing to think about.

 

they only shut off when your highway cruising

 

I really didn't want to get involved in this thread. I figured someone would have posted this by now. You can shut four cylinders down. It won't make a difference however since you can’t open at least one of the valves full time. If you do shut them down then all you have is four cylinders taking away power on the compression stroke and not giving anything back. The engines that do have displacement on demand have the ability in the valve train to open a valve so that the piston can move freely.
