Disappointed in the 6.2

Kickdown Mode
The accelerator pedal provides an
additional downshift after pressing
through the kickdown feature.
It requires extra pedal pressure near
the end of its travel to engage.

 

 

It all makes sense now... I noticed getting on it that if I really mashed the petal down it would finally downshift an extra gear depending on my rpms.

Let's remember than the 8 speed shifts faster than the 6 speed. It made the Corvette faster, it's not going to make the truck slower.

 

Here's the maximum speed in gear for each truck.

 

The 6 speed will hit 60mph in 2nd gear and the 8 speed has to be in 3rd gear. It ALMOST can do it with the 3.23 gears (59.3 mph)

I don't dispute your numbers but I never said the 8 speed made it slower and the term "shift faster" has a different meaning to a tuner.

There are a lot more variables to take into account than the gear ratios and one extra shift at 3 tenths of a second could easily skew the numbers in a short run of only 6 seconds... Especially if the shift is late in the run, which is the last thing you want.

 

As far as Vettes times... Oranges. Completely different calibrations in both ECM/TCM and their purpose is more spirited driving/track oriented... So it only makes sense for the Vette to show improvements in times every year, that's primarily what sells them. Well that and they go good with Viagra...

 

 

i would not put too much stock in magazine test numbers.

 

if 0-60 or 1/4 mile time stats are really that important to you, ask yourself, are you doing a full launch from every stop? is there a prize for covering distance in less time......in your chebby pickup????

 

if you are really going to race your truck, all that matters is the person in the next lane, not what a magazine ran in los angeles a year ago on a different surface, different air, different, driver, etc.

 

enjoy your own experience, don't base your life on other's.....your life, your perception, it's all your own. if you punch it and it makes you smile, who cares if it is 5.4 or 5.3 or 5.1? no one knows the difference unless the clock is running. and it's not.

Higgs- My self worth is solely judged by my mod list and 0-60 time. The eggs must not survive the trip home!!!

Just curious where you have seen that 0-60 time for a crew cab 5.3. Are we talking tuned? Not saying it hasn't happened, I just haven't seen anything close to that for a stock 5.3.

I'm having trouble finding the link I saw with the 5.3L times but here are some with stats on the 6.2L. Maybe I was mistaken on the 5.3 times. Sorry for the confusion since I can't seem to back it up right now. SMH.

 

I'm old school I guess in that I still pay attention to 0-60 times as a performance gauge. That's the most common "run" for me, coming off stop lights, so I like to see what numbers my vehicles post.

Remember that the 6.2 is easily the fastest 1/2 ton in the 1/4 mile. So if you're disappointed by that I'm not sure what else to say :)

61.4 mph for the 3.23 and 58.0 mph for the 3.42 with a 33" tire ;)

 

and a slight rev limiter bump, then....

 

of course, i have 3.23s with the A8 so I am good to go.

The Corvette has it set at 6600rpm...wouldn't mind seeing a dyno sheet to see if the power is still coming on or not at the truck's 6000rpm redline

There appear to be big dif's in the 6.2's. My 2014 has 3.73 gears, 6 speed, 23000 miles, and will burn on takeoff but is slow on acceleration. Stoplight drag races not good. But at higher speeds like passing it pulls hard and just keeps pulling. From what I've read some of it's torque management that a tune will fix. The 0-60 ET's reported on test vehicles exceed what mine will do...but the torque is awesome. Mine will pull most grades empty in 6th gear even at 80. Towing very good. My truck did loosen up with break-in so test driving off the lot may not tell you much.

If my 2016 isn't better, I will get a tune. The power is there but warranty is a consideration so it's a gamble getting a tune.

You have a Denali and 3.73 max tow? I didn't think the NHT was an option for Denali's but I could be wrong.

mine is set to 7000 but then again its a blown 416ci.... :-)

 

i raised and lowered the full throttle shift points on my truck, one of them as low as 5200 or 5400 RPMs in order to drop into max torque each shift.

You are correct, I have 3:42. Thinking of an old truck.

I'm pretty sure my '14 6.2 is NOT designed for e85...

My owners manual specifically states I MUST use 92 octane or higher.

I'm driving the bag off my brand new double cab 15 6.2 tonight... the truck hauls ass for a stock pickup.. even with lame ass 3.23s out back. At a 20 mph roll the stock sra's don't stand a chance.

 

We rented the local dragstrip tomorrow and that's how she is getting broken in... lol. See what it can do before it has 100 miles on it

Right, the 6.2's are not designed to run E85 from the factory

 

E85 is actually 100+ octane, but you still can't run it. More to it than that.

You could run it by changing out $10 worth of hoses/gaskets/fuel lines - E85 is corrosive to many plastics/rubbers - that and a tweak to the A/F tables is all you need.

 

No more to it than that.

If it were that easy, I assume GM would have done it, and put the FlexFuel logo on all their trucks. So I'm having a hard time believing there aren't some needed internal changes (possibly to gaskets, etc) to make it work.
