Actually, this is similar to the 15yr old TCCS system on the Toyota
It adjusts to your driving style, and before each run of every
event, I'll unplug the EFI fuse for about a minute and euthenize the ECUs

it'll take 20 seconds to idle smoothly, but it is a significant
performance gain on no brains -vs- learning the environment around it.
