Greddy Profec OLED
 

Hi there.My name is Elias and i am from Greece. I am an Evolution 9 owner and i just bought EBC (greddy profec oled) before i flash my stock ECU and i want to ask you if its nessecary for my specs. My car has forge actuator full intercooler kit, HKS induction, 340aeromotive fuel pump, full exhaust(76mm to 80mm) and i am planning to upgrade injectors and camshafts later.My engine is stock. As i read that this EBC doesnt have the option to tune boost per gear or rpm specific without MAP extension. Stock ECU has this option and i was wondering if this EBC is useless for me like some people say or its ok to flash my car with this EBC. I need your help guys please!

Hi, i Had the Same quetions in my EVO 8.
I flashed
my ECU with Tephra 7, and programmed the Greddy ,it workt well. Have you already installed the Greddy? Make testruns
and ask specific quetions.

It’s fine to use it but as it doesn’t allow gear/rpm boost control, you won’t be able to fine tune the boost.

I use the greddy, and I enjoy it.

Ok, ECU-Boost is more flexible and if you use a quicker solonoid quite as fast as the Greddy.
But with the Greddy you can flexible switch between 2 settings and have an overboost button as well. With Tephra it's also possible to swicht between two settings, bur if you snatch bad petrol you have to reprogramm your ECU.
