Wasn't Bean spinning his standalone over 6K??

How high could you spin yours if you wanted??

Yeah, thought he said it hit 6400 when he was having some clutch issues. Something about the crank wanting to go limp noodle up there.


The Nira I'm running will go to 12,000 RPM, been on some alky tractors over the pond firing injectors. My limiter is at 5500, and seen a couple of 6000 peaks when I was tuning the rev limiter. Can't believe it but absolutely no wear on the keep it in the block end of the rods. (Steel pistons)


The RPM limit I imagine is going to be a tough one in the stock ecu.....digging out a single tag, then making the rev limiter play nice there too.

The guys running stand alone's are running sensors that actually read what we are doing. The rail sensor I'm running that reads 30K or a bit better, just forget now is 0-3V and I do find it a bit more sensitive to the slightest voltage fluctuation.

look guys 6000rpm out of a cummins is not going to happen anytime soon, if ever..... The d-maxes dont even have 6000 rpm yet and that softwrae has been out for years...

just sayin dont get your hopes up.:Cheer:

Ummm......

Yes we are beta testing the Zuess controller. its coming along nicely, still tweakin some things with it but it has some serious potential as you can see. I have hit close to 7000rpms with it and with all the fuel I call for, just need more air up there. ...

You also were asking about not too long ago...

...I have been in contact with EFI about a few things and RPM potential has been my #1 concern, mainly because i need more rpm!
...
Click to expand...

And you claimed 5500 rpms...

Now, I may have just made an @ss of myself but unless you guys are blowing smoke, how can you say you 1)Have the highest RPM CR out there and 2) How did someone else claim to get more RPM?

I read on the destroked site. Our Ecms will burn up at 4500.
Injection driver circuitry cant handle anything above that.

What I can say about the 5.9L ECM is the CPU inside it is more than capable of keeping up with high RPM's. For the technical people, the CPU is the same one GM use in their gasser ECM's from about 2006 up, these will run a gasser up to about 8,000RPM with way more complex computations than the Cummins ECM needs to do. The scaling in the ECM's RPM calculations allows up to 8192 RPM!
So the CPU speed is not the problem, it has been suggested the Injector driver circuits are the issue, that may very well be the case because the charge capacitors need 'x' time to recharge to be able to fire the injectors. Switching them too fast may indeed cause overheating of the internals of the ECM.
However, soon we will be able to log the pilot, main and post injection pulse times, if it shows even just the the pilot & main are being used up to 3500+ RPM then above this turning off the pilot (and post) increases the available time the injector firing capacitors have to recharge.
Even though the pulse time is much shorter on the pilot, if the injector only needs to fire one main shot it's going to give the ECM more time to recharge the capacitors.

Cheers,
Ross

I want a lope tune....

In a more serious note I would like to see some improvents on the items below.

A more linear throttle
No throttle hang
Bigger injector rattle
Low boost smoke
Spooling large chargers

I will think of some more

X2 with emphasis on the bold. I can run a pretty clean low 11 with my smarty on 1 but it's still a trick to drive low smoke on the street, and quick changes in speed is not happening without a good cloud. Turning up my pressure box to run 17-18k like the 04.5+ trucks helps but I think it could be better. Pressure seems to run a good bit lower in the 03-04's.

Without a different VB, complete control will not happen in a 48RE....you might get some control, but it's not a fully electronic tranny like the Allison....now the 68RFE...it is:evil

The 48 isn't fully electronically controlled but I am curious to see what exactly they can control...if anything.

i have 21 logged passes of 56-5800 on each and every shift at that RPM, one hit wonders like those listed only ended up in broken parts and dreams....

BTW i was speaking in terms of stock ecu software anyway. i.e. EFI

Yes i could use more RPM, but EFI has not found time to work on the issue's, as there trying to work on the dodge stuff.

My question to Rob was to address this very questions on running aftermarket rail pressure and map sensors/transducers. We can get them from 0-5v and able to read 30k or more(I am pretty sure they won't like it though)like you have. I am pretty sure as you have stated that better sensors much make it much better to tune and get it running as it should. The aftermarket sensors should have a quicker response times and MUCH better resolution vs. stock.

6.7 l Injectors instead of 5.9 is what I am waiting for to upgrade injectors.

Here's a scope shot of the stock ecu ~4k. You can see how close the pilot is to the main, and yet could fire twice in that time. So that supports what I said above about loosing the pilot and the high side drivers should go a lot higher. The charging time isn't going to be what holds it back.

Pretty sure the low side drivers will handle it as well, as its relatively low current holding.

It's cool you guys are engaging the forums......lots of input here if you can patience the odd a$$hole or ego.

The CRIN3's are just way better when it comes to extra pressure, I just plain wouldn't run the 5.9's in that 30k range they can't take it.

I don't see the stock ECM however ever firing those, the current profile is so much more for the CRIN3's.

You mean they won't drop everything and work on something simple like that for you??? Wow....don't they know who you are?


Huh...who'd have thunk it!

it's really not that simple chris. Some of the best EFI tuners in the country are stummped on this RPM cut off, even Banks is haveing the same issue.

When EFI does find time to rectify the issue's it may take a day or a month i dont know, but they promised me that they would look into it once the dodge software is launched.:Cheer:
 
Banks is having this issue?? How? They run the high end Bosch standalone last I heard!

We've delt with the same limits on the Dmax sensors. What I can tell you tuning my truck and the 8 sec Dirtymax both making a lot of boost, is we have made due just fine with stock sensors. Would having better sensors help, yes on ultra fine tuning for sure, but for the 99.9% of the trucks the stock ones will work. Again, I've not logged the Cummins sensor speed and compared so kind of an educated guess at this time.

This chit way beyond me, but can I ask a favor??


Would the one that put "marco is jellous" in the tag section below PLEASE edit your tag for spelling.... Especially since someone called you out with a tag that says, "that's jealous you dipsht"....


LOL

Thats just been buggin me a bit...


Carry on!!
 
Wow! Very interesting information in this thread! I'm curious to see what all can be done with a 6.7! Subscribing...

LMFWAO not to mention they spelled his name wrong. Macro? WTF, I love it when people get online to talk $hit and they can't even spell correctly.... You could at least spell it phonetically marko is gelis :soap:
