FC3SPRO: 400hp on Stock ECU
Since alot of people in here recommend the Mild to Wild thread on FC3SPRO.com, i have finally read it. Now what is crossing my mind is that everybody seems to be running for standalone EMS’s early in their builds, yet the thread says that a stock ECU can actually run 400+ HP.
This interest me quite a lot since my HP goal is 350, but where im from its hard to find a decent standalone, and even harder to find someone who can work on it... So my question is basically, is the Mild to Wild thread trusted to “stage IV”? |
IMO, It's a good guideline but I wouldn't take it word for word. That thread is now 14 years old and pretty outdated.
While I don't doubt that you can make 400+ HP on a stock eco + a piggy back fuel controller, standalone ECUs have become more accessible/affordable and have way more features compared to stock ecu + piggy back. Which is why you're seeing more people convert to standalone. Myself included. |
poor tuning is a major cause of engine failure, its the best insurance you can get for engine longevity

I made 315whp on stock ECU with a Apexi piggy back fuel component. I have FMIC, Full exhaust, intake. Stock turbo, stock injectors. I knew some ppl who have a upgrade turbo who wre pushing 350whp+. I bet 400hp might be doable with the right setup.

hey could you send me a private messge with more info on your setup? Im really looking into about 300-350whp but on stock ecu since i wouldnt want anybody in my country to start tuning my rotary lol. But id like to know all the mods you had, like fuelpump, cdi, fpr, or any other mods please :) this was a long time ago but I believe my setup was Greddy FMIC Apexi S-AFC fuel controller Apexi Boost contoller FCD 550cc primary, 750cc 2nd injectors ( had them sent out and made bigger by RC Injectors ) Walbro 255 fuel pump custom made intake Racing beat Full exhaust / 3" Catless downpipe Stock ECU Thats pretty much it... Car was great - full boost by 2,600rpm, full boost 15psi stay to about 5-6k then would drop from to about 12-13psi. But the 305rwtq made the car a blast to drive in city. A HUGE part of this will be getting the car tuned right. My buddy is an amazing rotart builder and tuner. So I was lucky to have him tune the car for me, |
