Sorry, I should have been more specific, I never tried pulling anything from the original dme. The boards were burnt up and corroded inside, it lost the ground circuit for the main relay (among other things, I imagine) and I was hoping by grounding out the relay I could at least get communication with ista but no luck. I could run a vehicle test and with the main relay grounded (and maybe a couple other things grounded or powered, I don’t remember exactly) the engine would turn over but it wouldn’t start and it wouldn’t communicate. This was months ago, and I never bothered going any further with that dme.
So the read/isn is from the donor dme and that is what’s currently installed in the m5. Which is why I’m wondering if the CAS isn read-out by the mss6x flasher software is for the donor car’s cas or my currently installed (original) cas. Reason being is it seems to me that the software communicates directly to the dme over dcan and not through the gateway (unless I’m not fully understanding what’s going on in the background), in which case it would make sense that it would not be communicating with the cas at all and is only relaying information specific to the currently installed dme (from the donor car) and in turn only giving me the isn associated with that dme and it’s originally-fitted cas (from the donor car).
So based on what I think I understand about this, I believe the “cas” isn that the mss6x flasher reads to me is coming solely from the dme it’s communicating with. Which means that because the dme it’s currently communicating with is from the donor car, the “cas” isn is not the isn in my car’s cas but instead the isn from the cas in the donor car. If that’s the case, then my only solution would be to somehow write the “cas” isn read-out by mss6x flasher (which is the isn for the donor car cas) into the currently installed cas (which is not from the donor car). I apologize this description is so convoluted I’m just trying to be as specific as I can.
As for installing the donor cas, if I could simply throw it in with donor dme, go into winkfp and do some vin changes then that would clearly be the easiest solution. But I don’t know if that’s possible or not using the standard tools, and I’m not comfortable enough with unguided experimenting to risk putting myself in a situation that I need to frantically dig my way out of. The way it sits right now, everything is fully functional outside of running and driving, specifically the most important things like terminal control and elv function so the car can be moved around when needed, put outside and locked, etc. If I do something I don’t know how to reverse on my own, in winkfp for example as I have no experience with any of this until now, and the car gets stuck in my bay or in the middle of the shop, that will become quite the headache.
And in regards to ews delete and dme cloning and things of that nature, from what I understand (or at least believe to understand), that will still leave me in the same boat with having to obtain a separate software with those particular functions/features/capabilities to allow me to do those things - which I’m not opposed to buying as long as the software is worth it and has little to no user limitations - or paying someone for that service. My specific goal here is to eliminate having to outsource for this type of stuff. Not that I’m against paying an expert to do what they do, by any means; I have no problem paying for products, services, advice, tools, software, licenses, tuning, etc. But it would be nice to have a better understanding of all this to be able to do some of these things on my own without having to always rely on other people to bring a project to a close, especially in time-sensitive scenarios. My ignorance on the subject will without a doubt prevent me from flying solo all the time, but at least with the right tools I can put in the time and effort to work toward not being so heavily reliant on everyone else.
I do appreciate the response and suggestions, hopefully I can make some sense of this without needing too much handholding but I’m not off to the best start so far! Lol but thanks again for the reply, it is truly appreciated!
