might keep my car so what upgrades next, How long does a gallon of meth last? Options

[mk7celica]

I have my car for sale and did not have much intrest. So I might keep it. If so I have some money saved to mod my car. I had a ct20b installed not to long ago. Not sure If I should get a bigger turbo and aem fic? Or keep the ct20b and get a aem fic with 3 bar map fuel rail and bigger injectors? I want 325 to the wheels and I have added everything I could to my 2nd gen and I am at the fuel systems limits. Suspension is done so I am good there. Any ideas

Best move you could have made at this point.

One draw back to the PFC is that it has no Knock Control.....So make sure you have a very good tuner, that he is aware of this, and maybe think about hooking a J&S knock guard system on your car somewhere down the line.

It still logs knock and flashes your cel. It just doesnt try to retard your timing when it senses it. Really not a huge issue since the car needs to be tuned from the ground up anyway.

Anyway on ECUs with knock control, this is not precise because there is no compensation with knock threshold. So the knock control won't hear the noise in low RPM as you have set it for high RPM sound/knock.
The advantage with Power FC is that you can monitor knock live while daily driving, and it records the last peak.

Anyway, the max power ignition tuning isn't possible without a dyno. On a dyno, the peak power is obtained in timing advance much before knock is coming.

So if you get knock on a Power FC, with your advantage to monitorize knock, you have to retard back from 2-3 degrees the timing but max power is not really obtained.
Another big advantage, if your timing is set for 93 fuel, and the only fuel that is near is 91, you won't blow the engine. You can retard the whole ignition MAP in seconds with the commander.
