Lotus does not use a Toyota ECU. BOE has great tunes for the Series 1 Evora'sIf I do go with the supercharger I'd need to look at tuning options. I have found a few different sources that tune the OEM Toyota ECU's (R9K and Frankenstein Motorworks) just to name a few.
It seems that the Toyota ECU has an excellent ability to modify itself to take advantage of exhaust modifications and fuel grade, but I'm sure I'd need to tune for the supercharger. I know the Toyota Aurion did come with a supercharged 2gr-fe so I'll need to do more research on that.
Thanks for the help!
