Discussion and questions related to the course EFI Tuning Fundamentals
so what do you recommend to start tuning my 2015 TOYOTA Corolla 6 speed manual. 1.8L. Isn't better reflash or buy and standalone ECU.
there is not much if anything available to tune your std ECU as they are pretty locked up
and depending what canbus is used it may be a little tricky to fit a standalone ECU without a bit of research first
the best bet would be to ask around do some googling to see what is available
