I searched but didnt find any real information. So just asking VFR direct. Has anyone been able to unlock to tune a stock OBD-2 ECU? I've had several vehicles that I have been able to tune the stock ECUs and have been happy with the outcomes.

I don't think its possible. There's a few options for adapting aftermarket ECUs like haltechs eg:

Unichip looks like is just signal modifying box. Looks like I need to do some more digging, first figuring out what protocol is being used.

Does the ECU have a removable E-EPROM ?

Toyota's are notorious for not being crackable, always have been. An aftermarket ECU is possible but you gotta figure out what you want to do for controlling the transmission.
