I reached out to HP Tuners about this but haven't gotten a response. Can I tune my ECM without unlocking my TCM? I have 2018 A8 and know the TCM is locked, but to my understanding the ECM is unlocked. Installed a DSX Flex fuel sensor the other night and am looking at different tuning options, would rather not have to ship out / buy a new TCM if possible. Thanks!
