Re: 6.7L Cummins conversion project

I have read that Auto Enginuity with the enhanced Ford Interface will do tire correction:

http://www.autoenginuity.com/

http://www.autoenginuity.com/products/o ... -ei01.html

However when I look at the above page, I see that it only mentions tire size for the 7.3L and the 6.0L diesel.
So, before spending any money, I would go to the subforum on your engine in ford-trucks.com and ask how to recalibrate for different tire size.

Although this site is a diesel oriented site, it has the reputation for the best prices:

A bit pricey for a one time thing....

Perhaps we could do a community group buy thing here and pass the tool around..the logistics would be tricky....or better yet MGmetalworks creates a bootleg version/method and we "donate" to his engine swap project for use of the software/method.....just thinkin' out loud.....

Great excuse for a So Cal meetup; there would probably be a handful of local members that need speedo correction.

Re: 6.7L Cummins conversion project

Boywonder: There are those on the ford-trucks.com forum (aka Ford Truck Enthusiasts forum) for your engine that already own AE. And some of those members live in or near your city. So, after verifying that AE will in fact change your tire size calibration, post on the forum for your engine and ask if someone with AE can help do it for you. And also for giggles at the same time run some engine diagnostics. FTE is called the "Brotherhood" for a reason.

Re: 6.7L Cummins conversion project

I can see that it is about time for a separate thread about van electronics, module programming and CAN bus info....

Changing something like the tire size is fundamentally a pretty simple concept... There is a specific location in the ECU's memory that holds some numeric value for tire size, represented in revs/mile. Hand held tuners, software packages like AE and many others read the contents of the memory, convert those contents to human readable format and then allow you to manipulate the value of certain parameters and reprogram the memory. You can communicate with modules and read the data out of the memory without any fancy user interface style software packages but you'd better know what you're looking for because it isn't conveniently formatted for human consumption. Those purpose built hand-helds and fancy interface software have done the research and spent the time to go through the data line by line and interpret the contents so that you can easily read it.

Now if you're clever and too cheap to buy a software that already does the hard work for you, there are ways to figure out which memory locations are the ones you want and there are ways to attempt to convert parts of the data into something that might be readable. In a new thread, we can toss around ideas for how to isolate the information we want to find...but in this thread, I'm only going to concentrate on what it takes to get the Cummins running in my van. I will need to manipulate some values in the modules in the van so I do have a strong desire to find a way to do all this without spending much money..... BUT... it takes a lot of time to figure out even one or two things so for now my focus is on my specific needs in my specific application. If I learn things along the way that might help crack other mysteries wide open, I'll share my findings.

I think it is annoying to have to spend a few hundred dollars on a hand-held programmer just to change the tire size so I'm going to try to find a way to do it with open source software and cheap hardware (cheap meaning under $100). I think it can be done...Actually, I know it can be done. The companies who have done it before just want to make a profit off of it by bundling it into something you might not really need.

Re: 6.7L Cummins conversion project

Thanks for the info E350, I'll wander over to the brotherhood forum when I get a little time.

MGmetalworks: My comment above was half tongue-in-cheek since I completely understand the time required to capture and interpret raw data with little support; you appear to be looking at it like a treasure hunt which is great. It's sometimes hard enough figuring out the sugar-coated data that you get from a shiny new scanner, let alone burning new firmware in your various modules.

Certainly plenty of motivation and creativity on your part as slapping a different drivetrain in your van is not trivial, and will serve as an inspiration to others here.

Yes!

I'm a much bigger contributor on FTE simply because I know a bit more about E-Series vans from the cargo only aspect than I do about SMB's or their variants.

Typically FTE is just like SMB wherein most who contribute do so to share their knowledge and in the process learn more too. It would seem the brotherhood is anyone who enjoys tweaking and better understanding the vehicles we drive.

Both great sites with unique perspectives---I've learned a lot from both!

Re: 6.7L Cummins conversion project

With all the talk of hacking modules and digging in to the code to make changes, I thought I'd explain my somewhat cryptic message several days ago about making major progress on the ECM security.

Probably the biggest, most challenging hurdle to clear in this project is not actually fitting the engine and trans in the van. The biggest challenge is literally changing a few binary values of '1' to binary values of '0' somewhere deep within the ECM's memory. My comment about "MAJOR progress" refers to the fact that I have identified the parameters within the software that will disable the interdependence between the ECM and Ram truck's SKIM (Sentry Key Immobilizer Module). What does that mean exactly? It means that I will be able to run the engine with a dozen or so wire connections to integrate into the Ford harness and without any dodge specific electronics.

Sounds good huh? The only problem is that I haven't identified all of the right memory addresses for each parameter yet. I know the parameters and I know how to change them, I just need to find the right line of code to make the change. Still some detective work to do...there are only 88,000+ lines of code in a calibration file so I'll eventually find it.

In the process of identifying the security stuff, I also made a few other discoveries that may prove quite useful, especially for integrating the Allison TCM into the vehicle.

I don't have any fancy pictures of this ECM stuff...and quite frankly it is a little boring to see strings of numbers and letters... but I will soon be tearing down a NV271 transfer case for rebuild and retro-fitting of a speed sensor and tone ring. That should prove to be an entertaining series of pics. I owe you guys some good pics for all the boring nerd posts I've been making.

Great thread! Too many ratholes though...we probably need a F2F...
