For this particular model, given what it is as a sports car and the demand for a manual already, it makes zero sense NOT to offer a manual until the Supra MKV needs to go hybrid for all but the niche trim levels (GRMN, etc) in later model years. Jeff, your idea of pulling the code/parameters from a manual GRMN ECU is probably the only second best way to convert the early GR 6 cylinder cars to manual without having any electronic, sensor or emission test issues (for most states that have testing that is). Toyota really needs to put a manual into volume production though, not just on the GRMN. It is a limited window anyway and this is their halo sports car, not a Camry or even a Corolla hatch (which offers a NEW manual for 2019...). I can only understand their logic in being cryptic and stringing everyone along with the manual question if it is part of their plan TO rile people up who really want a manual version... and get them to be both vocal and vote with their wallets. Though I am a bit confused as to how more people buying the auto-only Supra is going to do anything more than confirm to Toyota corporate that people wholeheartedly accept there being no manual available. Do dealers note to the corporate offices every time they lose a potential sale on a Supra after a customer refuses to put a deposit down on a no-test-drives limited availability model because they made it abundantly clear that they refuse to buy or even put down their deposit unless there is a manual version available on the lot or to order? Toyota keeps saying "we will sell a manual Supra if the demand is there". Okay... so for the actual customers who CAN buy this car, how is this demand gauged when the diehards will see that manuals are getting scarce as of 2019 and they would be more inclined to shrug and buy one *now* from Porsche, BMW, Ford, Chevy, etc.? I hope they make the right decision. At the very least, Jeff, I hope the GRMN will have a stick so that we can pull its unique programming and cut and paste that into the automatic ECUs of regular GR Supras. That still won't allow such conversions to be legal in CA unfortunately no matter how functionally correct they are but for everyone else it would hypothetically be a good second best solution. Unless Toyota does add a manual to the GR option list, for CA customers who want a manual Supra it still seems like the only sure-fire options will be the very limited and expensive GRMN manual... or extremely risky and shady out of state registration for their manual-swapped MKVs.
