I would love to convert my car to an electric, but it’s an automatic so I’d have to spend as much as a new car to convert it.
A drop in ECU replacement and motor/battery would be great, but I doubt the auto industry or the government is going to allow the sale of third party drop in ECUs.
It’s not about converting the car.
I have a 2009 Chevy with an automatic transmission. I’m order to convert it to electric, the ECU would have to be replaced so the car knows when to shift to a higher gear without a combustion engine.
Because of environmental reasons, ECUs are pretty tightly controlled by the government. I don’t know if any company even exists that can sell an aftermarket ECU. There’s plenty that can hack or reprogram ECUs, but even that is becoming increasingly regulated and legally questionable.
