SS-III vs ST205 on track Options

Why does it need to be changed change to 1zz-fe ecu if you have the power-fc? doesn't the power-fc alone let u raise the rev limiter? does it not control a standalone ignition system or even the stock ignition system?

I'd understand if u were using an safc, but a power-fc?

you dont get a power-fc for the redtop beams, the 1zz-fe is very similar electronics wise to the beams except for the ignition circuit, so i made a harness to allow the 1zz-fe power-fc to work on the beams redtop.
