CA to change smog laws again come Monday
This is where i'm at right now in going to factory - 08 gsr with last stock rom having had the first-year 5krpm hesitation fix/tune recall applied to it. Which i'm guessing belongs to 52680017/0018/0020(thanks razor and everyone who made it possible for all that info/data to be accessible).
Or go with one of two final revisions for that model year - 52680024 & 0027 of which they probably belong to tsb-13-13-009 & sc-13-004 - they both share the same software P/N too(according to the PCMUpdates.pdf on the mitsubishi tech info site) which makes it trickier to choose which to go with.
Afaik that(sc-13-004) was the last ecu-related fix to be provided to owners of 2008s through(possibly) 2014s that isn't dependent on warranty coverage & is provided at no cost as stated in the customer communication letter, so perhaps that gives it more weight and is the rom used as the basis to determine what data to use as the -final & most up-to-date- in state databases for testing purposes.
Plus theres another difference on the communication letter sent to dealers for those two bullitens(pulled from the nhtsa site).
On page 12 of sc-13-004 there is a strike-through on the instruction line of "The Control Module Label is NOT used for this reflash. It should be discarded." Whereas on page 12 of tsb-13-13-009 the instruction line is unaltered.
Maybe becaue the change made from the sc-13-004 flash more notably effects emissions so it was mandatory to have the sticker placed after completion? Which again, might give it more weight for emissions testing.
Anyhow, all that to say that it's true, just gotta decide what is appropriate for each situation. Though with some uncertainties that kinda make it tricky(but with signs pointing to the most recent rom needed?) how to pick what exact rom revision to use I can see how some flash a valid model year rom and ended up not passing as it wasn't the exact rom revision and resulting cvn that was being looked for.

why can't you load any stock ROM then have a dealer update it to the latest?

Assuming the dealer visit goes without issue and they don't put up any resistance for whatever reason. Which they shouldn't if everything is back to how it needs to be.
It's just an extra step that needs to be taken as opposed to going d.i.y the whole way.
Hey guys - it is not just a case of loading the right stock ROM ... it must also contain the correct CALID (which matches the ECU outer case label plus variant iterations AA, BB, CC, etc), a valid CVN, and a matching VIN.. The dealer update load will load the correct ROM for your model year plus any required TSB revisions, and finally they will add your VIN to the ROM. You can do all this yourself, but it requires a detailed investigation of the ROM to find all the locations you need to update, and unfortunately this is hard and is not currently public knowledge.
Silevx - When you get your 2008 to pass the ref, please post up your model year, ROM variant, CALID, CVN1 and CVN2 so the community can learn from your experience.

If I can avoid having to go the route of acquiring a 2nd ecu, then yeah I plan to share the details of this after it's all done & hopefully the info provided will be of use to others.
