Cummins development progresses

[SGFastMax]

ok thanks

[cumminsDK]

So any updates on the scan tool progress?

[FUBAR]

Update please?

[Blacky]

The latest Cummins beta version is being uploaded now and released to the beta testers tonight.
This is likely the last Cummins beta release before we make a public pre-release.
We haven't announced any release dates publicly as we need to propagate that information through our reseller network first.

I expect it will be available well before the end of May.

Here is a little more detailed update on our progress.

Last week we expanded our Beta program to include several additional testers. This was done to help us speed up the process of our testing as well as expose the software to fresh eyes to see how new users will manage. We needed to see how users who hadn't been exposed to custom tuning took to the process. Not only have we had excellent feedback from these new testers regarding parameters and how the tune tool and scan tool interact, it's also been very helpful for our documentation and support network for when we do release. We have produced a quick start guide which will be given a once over from the Beta testers too.

With respect to the software, this is what we've been working on recently:
- added support for new some new operating systems (they keep popping up).
- injection timing and fuel pressure controls confirmed as working well, commanding 26,000 PSI no problem with verification on the scanner it's doing it.
- full control of post and pilot injection confirmed as working.
- currently testing tire size adjustments (we may add a calculator in addition to current controls).
- Wastegate control - we've made good progress on this feature and people have been able to remove boost foolers.
- auto door lock disable feature in testing (mixed results).
- Scantool PID group selection working well, although we may need to retrain our existing GM customers - this approach is very different to what they are used to. We expect this method to be far more helpful with users assisting each other.

What we are still working on:
- fuel hang - appears to be operating system related. The issue is resolved on some trucks via tuning, and is still being experienced on others. We are compiling a list of OS's that it works on and doesn't work on to try and resolve this completely.
- RPM limiters - we've had some success consistently lifting the limiter to 4200 and removing that huge back off to 3600. We haven't hit the magical 5000, but we are still actively working on this though not as a priority for release day.
- door lock disable feature is working on some trucks but not others. Still need to do more digging on this, although it won't prevent us releasing (nice to have, but unnecessary)
- flashing tunes from one vehicle into another. We need to finalise testing to ensure there are no security issues or no start issues.

What's needed for us to release?
- The testers (and ourselves) need to have a better understanding of certain table affects on the final injection pulsewidth algorithms and the Fuel Pressure control systems to support our customers as knowledgeable as possible.
- Keep testing the RPM limiters.
- Finalise documentation (will anyone read it??)
- There are a few minor fixes needed to the software, and then I expect we'll have one more full beta release before we are ready to go public.

We just want to make sure that when it's released that all tuners are going to have the ability to produce better tunes than what is currently on the market today. When I say better, I don't mean the highest horsepower or highest RPM, all that will come, I mean something the drives smooth like a factory vehicle yet performs significantly better.

Cheers,
Ross

Thanks for keeping us updated.

Does it look like there may be some trans tuning available in the future? If anything, to control converter lockup? That would be great if it's possible.

I would really like to know this too!

Yes, some trans control will be included, but not on the first release date. Although the electronic side of the transmission is relativity simple on the Dodge (compared to say an Allison), we will need to get our Beta testers to do some testing on the tables we wanted to include.
