Anyone messed with the ECM on the newer 3.0L LM2? 2021 to be exact, not really asking for deletes, more on the ability to turn off the auto start/stop permanently. I see HP tuners supports them but wasn't sure if those tables were available
LM2 tuning?
- Thread starter PureHybrid
- Start date
Moved this from chat into its own thread in LM2. Are any tuners north of the border doing friendly tuning to them yet?
As to stop-start, is anyone making a hood-release harness adapter for them like some other vehicles do to defeat stop-start?
EDIT: yep, they're being made. Just google "LM2 stop-start harness".

Thanks.
Yes I've seen the Auto Start boxes that basically just "push the button" for you every start up. Seems to be the cheapest option but I like permanent solutions, we'll see
What about the 2023 version? Can't seem to find anything on them yet except one place and you have to swap the ECM and TCM
The info I've found has HPT charging $800 for their ecm service on the E66 which supposedly covers 2021+, they claim full access but I haven't seen anybody talking about the auto start function being part of the ecm or if it's in the bcm
I would double check if you have a E46 or E66. The pickups had the E46 up to 22 but SUVs got it sooner.
I'm 99% sure the controls are in the ECM. I'll look into it more later

So, yes. The Start/Stop controls are in the ECM. But HP does not have them mapped. Nothing a little custom mapping can't fix though 
About on the same level as them running 20wt oil
I haven't seen it myself, that's what my brother said was it calls for 0w20. I think he's just going to run T6 5w40I guess I missed that one.
?
Vee S E is the only one I've found for the 23-up
But will anyone do a def bypass tune??
