RPM for the 6.7

[dodgeram082500]

I'm a little behind the times on the 6.7 trucks. Did we ever get the capabilties to fuel at or above 4000 RPM on manual trucks?

[4NEATR]

you sure can programming wise, but just make sure you have the hard parts to back it up

[2007 5.9]

Rod ratio on the 6.7 isint favorable for high rpm conditions.

[dodgeram082500]

Nothing left untouched on this motor guys including rods. Thanks again guys.

[2007 5.9]

Yes, Fleece has had fueling over 4k.

It's there, might have to work at it, but it's been proven to be there.

[dodgeram082500]

Thanks but no offence to fleece or anything else we would rather do in house custom tuning. It will be far from the first cummins we've pushed over 4000 RPM ,but the first 6.7l. So is this way to push it above 4K avaliable in the public release or is it a beta thing? dont really need to know how to do it just if we can do it. Thanks again.

[WisconsinHick1]

You can do it he was just stating it can be done as Fleece has done so.

[dodgeram082500]

Much appreciated guys yall helped save us alot of trouble

[Duramax 6.6L]

Could you please tell me what table or tables controls the fuel above 4000 rpm

[kaiserbailey]

Could you please tell me what table or tables controls the fuel above 4000 rpm

All of them... :nixweiss:

[2007 5.9]

Nothing left untouched on this motor guys including rods. Thanks again guys.

Did you address the rod ratio issue, or just put stronger rods in, in hopes they don't fail?

[dodgeram082500]

The motor is using a 5.9 crank, Carrillo rods, as wells as several other internal mods to make durability and rigidity issues minimal

Unfortunately I have been sidetracked on the RPM chase, but from what I recall when testing some OS's didn't play nice and still have hard RPM cuts at 3900 RPM (or there abouts).

[dodgeram082500]

any ideas what operating systems were giving the trouble?

[GMPX]

I thought that would be the next question :grin:, the answer is sorry I don't remember, I'll have to see if I still have on my work computer the files that Brayden was working with and I'll let you know what OS it was.

[dodgeram082500]

Thank you sir

[GMPX]

11551035 was the one he was running.

[dodgeram082500]

Is that the one that gave trouble or worked thanks again

[GMPX]

11551035 worked, doesn't mean others wouldn't either, just that it did.

[dodgeram082500]

Thanks once again

We continue to work on RPMs in testing. Today the 6.7 finally broke the 4,000 RPM barrier hitting 4,166 RPM. Pics to follow

Cheers
Cindy

[dodgeram082500]

Good deal Cindy!!! Glad to see you guys are working on that

4000 RPM's on a stock ECM 6.7 has officially been broken.

This is running a manual file on a 47RH.

Here is the actual pull to 4200 RPM's. This wasn't a hard pull, I simply rolled into the throttle in first gear and took it up to 4200 RPM's.

The light you see come on is a MIL for torque management. I simply need to extend the torque limiting table out beyond 4200 RPM's and we'll be all set.

Tomorrow she's gonna get a workout.

Here it is getting wound up to 4400 RPM's with full fuel.

Very nice

[Duramax 6.6L]

What is the max rpm you think we will be able to get to

[C Murda]

is this kind of thing only possible through a manual trans or can an auto 6.7 be able to go to 4000 too?
