Drive in tow mode! :lol:

But as for being able to turn it off I'm not sure. I drive a truck a lot with the 4 cylinder shutoff and i agree its annoying when you want to try and pass someone and there is that huge delay! Hopefully someone else has knowledge on this

 

I turned it off with my Superships programer.. Best thing I ever did.. MPG's did not move much so well worth doing it..

 

Around town use your manual mode in the 5th setting and it will never come on. No need to spend any money on aftermarket tunes that will indeed void your warranty.

 

What is manual mode in the 5th setting and where do you find that at? Thanks

 

I can not stand my truck switching back and forth from V8 to V4 anymore. Is there any way the dealer can disable this stupid feature or am I going to have to buy a programmer to get rid of it? I need help because it really bothers me how much it switches back and forth.

Thanks everyone!

Your best bet if to get a custom tune i know black bear can remove the v4 mode or like enkie said get the superchip which i never knew they could do

No need to spend any money on aftermarket tunes that will indeed void your warranty.

Ok i dont know where this guy is getting his info to but i never had a problem with a custom tunr or programmer on my silverado , Cobalt ss or our 2500hd work truck

 

Go ask your friendly neighborhood Chevrolet dealer the following question- Mr. Service Manager, I have an aftermarket tune, does it void my warranty?

Se what he says and please report your findings.....here.

 

LOL thats cute. But first my dealer has got to prove that what ever happen to my truck was becasue of the programmer same goes for all my other aftermarket parts. i had a stage 3 cobalt ss never had a problem getting warranty work done same goes for my silverado

 

Plus Most programers can switch back to Stock in 5 mins.. I always do that before I go to dealer for Warr work. And I have the Superchips Sticker on the side window of my truck.....:gasp:

 

My dealer up here in Canada has a programer that does not void the warranty but it cost $550.00 plus tax. It only shuts down the V8 to V4 mode.

 

I've gone into the dealership in many different cars in trucks that were still covered under warranty and I don't think I single one of them was stock. Maybe we buy enough vehicles from our dealer that they love use or as long as what's wrong has nothing to do with the aftermarket parts so they still fix it. But back goths topic, I don't have the 6 speed but I've never had an issue with v4 mode. I took my tune off probably 8 months ago to sell it for something new. I've yet to figure out if it's custom or diablo intune

 

Ok-so your not asking him then? You just said you don't where I get my info. SO- Why don't you ask your service manager at your local dealership and provide us with what he said. See above for question.

 

ive asked them along time ago bud back when i had my old cobalt and they will say the same thing everytime i ask them. Gm has got to prove that the reason something went wrong on your truck its in what ever act they got. My truck just got back from doing warranty work i had 2 ball joints gone a wheel bearing and hub gone and my transmission lines where blown all of it was under warranty.

 

Obviously, the work you had done is not related to motor/transmission operation. You blow a piston, burn a valve, or have ANY INTERNAL transmission issue-your powertrain warranty will be useless with a tune. I want to remind everyone-NO MANUFACTURER OF A TUNE WILL STATE it does not leave a footprint even if you change it back to factory tune before taking it in.

Then in a questionable denial of claim, try going up against the WHOLE TEAM of Gm's Lawyers. One better have limitless resources.

In addition, if you feel manufacturers don't deny claims "because they can" spend time over on the Ford Forums and see how Ford is denying seemingly legitimate warranty work on their lousy diesel motors.

 

ok so explane to me when i lost my engine in my cobalt SS and they warranty it since they did the work when they did my stage 3 you cant all tunes leaves a foot print and it all depends on the dealer that the truck is getting work done to it.but whats the point of tell use if we cared so much about it all of our trucks would be stock until the warrnty ran outand ford might be doing it for there lousy power strokes thats fine but my f-150 dont need a programmer at the moment since i can remove my top speed by the truck it self. but when i do start the upgrading in the f-150 ill have a custom tune on that truck aswell including a twin turbo casue warranty still dont mean **** to me.

 

So....tuner is the only way to turn it off? My wife has an '11 and she wants it off too.

 

My Silverado has the V4 mode and it has always been seamless when going from 4 to 8 cylinder and back. Although for the small amount of time it spends in V4 mode I think it's more a gimmick than a actual gas saver. JMHO

Yes but some people say gm can do it which i never experince since i asked them when i first bought mine in 08 and they told me they couldn't. Now becareful caus eonly certain tunes will turn it off. I know any custom tune like black bear wait4me and wheatly can do it if you ask them and someone said superchip do I know hyperetech dont turn it off since i got one but im getting rid of it down to road for a custom tune myself.

 

You may have a special relationship with your dealer. However, all it takes is ONE DEALER to enter it in to their (GMs) NATIONAL COMPUTER NETWORK and your toast.

 

Interesting posts....I just bought an 09 SIlverado and did not even know it had the v8-v4 mode until I was playing with the DIC display. I played with it a few times, and it did not seem to go into v4 mode much at all...I really have no issues with it when driving.

On the other hand, my son buys cars for a dealership and I often go with him to bring them back after purchase. Yesterday, I drove an 07 Impala SS with the 5.3...super car. Anyway, we drove about 140 miles on the hiway, it is spent about 60% of the time in v4 mode and got 27+ mpg....the AFM seems to work swell for these cars. I am not so sure how much it helps the heavy trucks....I have yet to see 18 mpg hiway with the Silverado.

 

I did a performance program with superchips programmer, but my mpg did drop from 13 to 10. This is also with a Vmax 6.0L. Power increase with this motor is incredible tho.

 

Im sorry CKNSLS, there are companies that do claim that their programs do not leave footprints. One company that I know is wait4meperformance. Im just putting it out there so there's no reason to be hostile.

 

I have a Diablo Tuner. Does away with the 4 cyl mode, shift points can be adjusted, speedo calibrated, injector trims adjusted, 3 settings to choose from instead of being stuck with one tune. Reads codes thru the OBD port and can be removed easily with no trace of ever being on the truck. They run around $350. I have to take mine off before going to dealer sat for oil consumption issues. Oh yeah.......when you install it......Its married to your truck tho!

 

Kyle - is it on their website? If it is I don't see it. Just curious. Not being hostile.

 

Around town use your manual mode in the 5th setting and it will never come on. No need to spend any money on aftermarket tunes that will indeed void your warranty.

Can you explain this process a little bit better? Turning off the AFM is a question that comes up frequently here and this is one option that may be appealing to those who do not want to purchase a programmer.

Quite simple actually. Just place the shift selector to M and before taking off push the up arrows on the gear selector 4 times until the dash readout reaches 5. Then just drive it like a 5 speed up to around 65-70. She'll never go into 4 cylinder mode and will upshift and downshift automatically through 5 gears. Unless of course you push the up button one more time into the 6 readout postion or run it in auto select.

Thanks for the additional info! It will be helpful when people search for AFM topics.
