Oh, I should add, we just had delivered the new updated V2's with the SCI bus support, so development can continue on full steam ahead with Cummins again.

So does this mean old V2 units will not work for cummins support when it's released?

It means the CAN based Cummins can be read with existing V2s (based on a previous post) but 03?-05s are SCI Bus and will need to have the SCI bus updates (dont know if its just hardware or firmware, I assume both).

See Andrew's post: SCI/CAN Cummins support

It is a physical hardware change to the V2 internals, so the SCI support is unfortunately not able to be enabled by a firmware update alone.

Update time.
We have successfully implemented re-flashing in to our version 8 development software for the 5.9L. So at this stage all technical challenges have been completed, we have a few things left to tidy up before we would consider releasing this as a beta.
One of these issues is more an issue in the ECM itself. Anyone who has ever used the Tech Authority system to program a 5.9L will know you have to go through a VIN learn after the flash is complete. This is because there is IMHO a bug in the ECM's reflash code handler that dictates you need to do a full reflash of the ECM even though you tell it to only write to a small section. In doing so the ECM clears out some critical memory area that needs to be rewritten before the ECM will come back to life correctly.
It's not a big challenge to handle this properly and we will be testing some processes shortly.

To answer the question on the old (existing) V2's working with Cummins, we are going to allow an upgrade to those V2's that will allow them to work with the 2006+ ECM's (the CAN based ones), this will not be a free upgrade, but it will save you needing to buy a whole new unit. Upgrade pricing has not been set, we will be having discussions with our resellers on what they feel is fair for everyone.

I know everyone wants time frames for a release, I don't want to set any false hopes as we have a pretty busy schedule (including overseas travel) before the year is out and Paul (the main software guy) is recovering from a pretty serious back operation, however we are 100% focused to get 5.9L tuning out as a beta before the year is out.

FYI, Below are the warnings shown with the Tech Authority factory on-line programming software.

:lookaround:

I bet if you have to ask, you can't afford the supporting mods... :devil_2:

Supporting mods.......hell I can't even afford a diesel truck. But my customers can !!

Hey Ross are we going to get CSP2 / CSP5 ??

Switchable tunes will of course be something we look at for the Cummins but definitely not before everything else is sorted for them. There is certainly enough space in the ECM's memory for such modifications but I don't know what sort of spare inputs it might have.
