Turning off cylinder while driving on high way

[lsv_palana]

Hello dear friends. As i know there are ability on our 5.3l v8 lh8 engine to turn off half of cylinder while driving on high way.. how to make it on hummer h3 ?

Sell it and buy a Tahoe.

Lol, I don't know why but that made me laugh more than it should.

Long story short - DOD isn't going to happen on an H3, sorry.

That's a condition I try to avoid! Dead rotating pistons and rods sounds stressful on everything else.......

Thanks for answering. But we have a same engine with tahoe. How they make this ?

Be happy with the truck you own or sell it

If you want less power on the interstate we can swap engines.

Lol. Clearly this is not going to be the crowd to help with your questions. I'd recommend a google search. There are many helpful resources on the web.

It's in the programming of the ECU, while it might be possible to take the code from the Tahoe programming and splice it into the H3's programming, it would probably require a fair bit of work and debugging to get it to work right. I really don't think it would be worth it, if it really is even probable to do. So unless you know so someone that can decipher and recode GMs code, I'd just be happy with what you've got.

I don't think it's an identical engine, even though they are 5.3L V8s. I know that the 6.2s have different hardware in the engines with cylinder deactivation vs those without

Yup.. It's not just software. 06H3 found this out when he did his swap.

Well there you go.

It's just a funny idea for an H3... I am praying to the power gods for every ounce of power no matter what the speed is and you want to reduce power for fuel. I would be happy getting 5 mpg if I had a great running V8 under the hood .

I think cylinder deactivation was meant for those trucks with a 6 speed. The I5 with 35s struggles to keep 80 mph in OD on flat grades with the 4.56 gearing, how about doing this with 4 cylinders and 4.10 diff ratio!
