Cummins 6.7L Overhead Chime Public Beta software

[cindy@efilive]

UPDATED NOVEMBER 18, 2014

***Files now included in Oct 28, 2014 (or later) software release***

Ross has spent a lot of time working through the 6.7L overhead chime issue. We had hoped to have a permanent fix publicly released before we left for PRI, but unfortunately we have run out of time. All is not lost, below is link and instructions to a public beta for these features which has been extensively tested by our beta testers and a number of individual customers who have contacted me over the last few months.

To install these files, Customers MUST first update their V7 software, V8 software and firmware to our **REMOVED LINK**

NOTE: PRE-RELEASE SOFTWARE is ONLY available via manual download. PRE-RELEASE SOFTWARE (if available) is listed on our DOWNLOADS page BELOW Public Release software.

Before you install these files, you should know that these in this format MAY NOT become our permanent fix. There may be some slight changes between public beta and public release.

These files DO NOT cover all OS's but here is the list of OS's the fix can be used on.

There are changes to be made in a number of places, the first is B7500 - see dealer reminder timer. Extend this to 360. (Timer is now set to chime every 6 hours).

The second set of changes is under F2000.

Below is a picture of the new tables



It's hopefully self explanatory on how it works, just select 'Not Used' next to the DTC you want disabled. If you need to re-enable a DTC just select the correct P code from the drop down list.

DTC's have multiple instances, so make sure you catch them all.
If you want to quickly disable a DTC, just select the cell you want and press the letter 'n' on the keyboard rather than using the drop down list.
One thing I would like you to keep an eye out for is a mismatch of P codes, eg, instead of it showing this:

P125B "Power Enable Control Circuit High" P125B
It might show this
P125B "Power Enable Control Circuit High" P1096 << that would be wrong

Cindy, I think it needs to be added that this is not a sure fire fix for the overhead chime. We are still getting it on several trucks, but the timer and enhanced code tables help to minimize the issues. It is still likely that problem trucks will still have messages with this software.

well guess i'm gonna need a little help getting this to work? so how do I go about installing this over the latest V7 update?

Yep ran the update a couple times I have the nov 7th and none of the tunes are showing the B7500 timer or the F2000 part either? I must be doing something wrong?

Hey, I'll try anything at the moment--thanks for adding this ! I think you're very close to a permanent solution.

[CGASTON]

I know that this is wishful thinking...... But is this an update for 2013?

[GMPX]

As in 2013 models? No it isn't, we haven't got the 2011-2012 done yet.

I know that this is wishful thinking...... But is this an update for 2013?

2013 trucks are a whole different animal of an ECM I hear. Not good news.

Sure you can pay Bully Dog some ridiculous amount of money to open the ECM up, but nobody has hex editing for it yet that's stable...Ryan tried, but don't think it went well.

While this update will kill the "See Dealer Reminder" dinging every 10-min it doesn't stop all the OHD chimes...so its a small victory.

Thanks for the great work guys. While this is just a small step forward, I am happy that as a user, I now have the ability to change this and not have to go through one of the beta testers. Not that they haven't been great about making the changes but it's just nice to not have to bug them for something some menial....

2013 trucks are a whole different animal of an ECM I hear. Not good news.

Yeah, 2013 went to another ECM again.
2006-2007 use a CM849
2008-2010 use a CM2100
2011-2012 use a CM2200
2013+ use a CM2350
Really, a two year life span on ECM's? GM gas cars still use the same ECM from 2006 to 2014 models on some engines.....and they went broke!

While this update will kill the "See Dealer Reminder" dinging every 10-min it doesn't stop all the OHD chimes...so its a small victory.

We still get mixed feedback Les, some people we've sent this out to have an all clear on all fronts.
