Thanks for the vote of confidence Jake.
We decided to continue from the 5.9L ECM to the 6.7L simply due to the fact it's all CAN bus based. It's probably going to be more of a challenge for us figuring out the old SCI bus that it is mapping the actual ECM.
I'm going to make an educated guess that the earlier 5.9L's will be very similar to the 2006+ ones, so most of what you see in the 2006+ ECM will be in the earlier ones.
Essentially it looks like Cummins started from some base code back in the 2004's and built up to where it is today with all the additions probably due to meeting tighter emissions. What we've done on the 6.7L so far would indicate that the concept behind how all the tables work is the same as the 5.9L, just more of them.
Time frame for the SCI ECM though, I hate giving time frames because who knows who hurdles we may hit with the projects prior to the SCI ECM, but being a realist, it might not be until 2nd quarter of 2012.
Cheers,
Ross
