Tuning options

I’d rather not out the companies that I have found on a public forum, but I’d be happy to share the two that I have talked to so far via pm.

Please do

Several companies out there offering a single tune without an ECM swap, but none of them are emissions friendly, and they do not offer transmission tuning along with it.

Between the cost for one of said tunes, and a Randy’s tuneless valve body, you’re back up there with the cost of an ECM swap.

It’s an expensive proposition either way.

Several scam companies yes no legit company will offer that as the 22+ ecm is still not been able to be cracked. I believe they can be bench flashed but that would involve you sending the tuner your ECM.

The shop I have been talking with are capable of flashing the ECM in the truck, with the use of their computer/hardware that you can rent from them. Two running 2022’s with a weight loss regiment that I know of, running their tunes, in which the ECM was never removed.

I still have the emails from my original conversation with them, I just decided not to pull the trigger since my regen issue seemed to magically knock off without much reason, and I do like having a warranty.

They are likely doing the “bench flash” in the truck by only disconnecting the ECM and connecting their connector to do the flash.
 
My first Ram diesel was a 2004.5 2500 and I was getting poor fuel mileage without towing. After talking with the mechanic at the dealer he told me that around 50K miles I would see a bump in fuel mileage at 100K mileage would go up more and at 150K would be what I could get. Towing a 11K Lb 5th wheel that is what I experienced. I traded it with 193K on it and could get 12 to 14 MPG towing. I am now on my 4th Ram diesel, 2024 3500 dually, towing a 40ft 17K Lb 5er and getting 8 MPG with less than 10K miles on the truck. When replacinal a truck
Aways get a truck to pull your next trailer, not the one you have today!

I need to talk to this shop. I have a 22 with 105k miles and the dealers wants over $6k to replace all my ****. I don't trust the diesel dudes kit. I'm stuck
 
A few months ago I found someone on FB Marketplace that was offering tuning services on 2022+ Cummins trucks with locked ECMs.
We exchanged a few messages and the guy said there is no need to remove or replace the ECM, just bring the truck to his shop.
I forgot his username and didn't save the messages thread where he described the software he uses. I think his shop is somewhere in N Texas.
 
Anyone have experience with Cummins software called Calterm?

Be aware the 22+ ECU may be hacked for tuning in some shape way or form but the gearbox tuning cant and both needs doing to get the proper effect and the only way is buying a 21 unlocked ECU

that makes no sense nor is it accurate. Some tuners have been able to bypass the bootloader and tune the 22ECM without a bench flash others have required an ECM swap or at least send off the ECM to be benchflashed to remove the bootloader security. . Once you have access to the ECM thats all you need to be able to flash a tune. The 68RFE uses a integrated trans tune with the ECM where the Aisin has a standalone TCM and can be tuned separate.

So you saying the 24 ECU is cracked?

Your post said 22+, not 24.

The point is if you can tune a 22+ ECM you have access to the same trans tuning as a 21 ECM.
 
The 22+ ECUs have not been cracked, someone above hinted at how it’s done with calterm.

They can only alter the non HO ECUs to disable the emissions (0hp, or very limited added power) regardless of what they claim. Even then, it’s hit or miss with the ‘tuning’ depending on who’s doing it.

Yes I did as my understanding is 22,23,24 model years ECU have not been cracked yet hence buying a 21 model year unlocked ECU to do proper tuning. The tuners here in OZ go down that route, and have repaired many 22,23,24 model year transmissions because the guys that claim they can tune the 22,23,24 model year ECU’s cannot do the necessary adjustments to the transmission side of the ECU and damage the transmission's after they have tuned them, these failures dont happen instantly but within 10-20,000km depends on use, the harder it works the quicker it fails.
This is what was explained to me if I was considering any tuning.
My apology's for any mis information it seems tuning is different in the US, so ignore my previous post or the managers can delete it.

I haven’t seen transmission failures from it, however I have seen very poorly running trucks and bricked ECUs from people who shouldn’t be using calterm, let alone ‘tuning’ vehicles.

Until they are able to get around the bootloader protections like on the earlier ECUs there aren’t many options beyond the ECU swap method for the 22+ trucks. There really isn’t any incentive in the industry to do so, EPA compliant or not (it’s reflected pretty well in the price for the compatible ECUs). I also wouldn’t hold my breath on the old days of tuning, the EPA hasn’t slowed down on prosecuting sellers of defeat devices, regardless of what they say on YouTube.

They are likely not tuning the trans properly I would be willing to gamble its more the tune than not being able to tune properly. Plenty of 22+ trucks tuned without trans failures.
 
Apparently Diesel Patriots out of Canada can delete with factory ecm just a delete no power increase anyone used their stuff yet?
