There is no aftermarket ecu capable of running your automatic... Not without some heavy reverse engineering on your part, anyway...

I did come across a fellow on another forum that claims to have an automatic IS300 up and running on a transmission controller he built himself after reverse-engineering the system. He doesn't share how he did it, nor does he offer them for sale.

So basically - you'll need to keep your Toyota ecu in place (and connected enough) that it can continue to issue correct commands to the transmission.

Neat! Was unaware of that.

FWIW: An electronically controlled automatic requires "calibration", so something like this is not a plug and play. It'll require considerable effort to act like you think it should.
Never said it was PNP. Hesse "PRO" in the description.

Someone on a forum used a Dicktator Transmission Controller for his a650e swapped SC300.
