Hi, I have a question.. I have a series 1 s14 with s15 motor and have found a power fc.. just wondering what benifits i will get from it. What power increases can i expect to get from stock ecu? I am running stock t28 (bush style) with front mount and 3 inch high flow exhaust system. currently running about 15psi and imagine at best i would have 165 - 175kw atw.. my aim is around 200 rwkw on stock turbo.. would i be able to achieve it with a power fc and tune? thanks in advance

My S15 had 201rwkw with your mods plus Z32 AFM, mild 'step 1' cams and nismo fuel pump/740cc injectors on 15psi. Some ppl claim to get that much power from the stock AFM and injectors with a power fc/tune, but i'm skeptical.

The Power FC itself does not necessarily give you more power just by plugging it in. The power increase comes from the ability of being able to fine-tune the air/fuel ratios etc throughout the rev range to make use of the other supporting mods. It is also a safety mechanism as it allows a tuner to compensate for each car/engine's individual characteristics.

These days, a nistune ECU is also a decent option, but i haven't had any experience with them so can't comment.

Dropped it off at the tuners yesterday, picking it up today (unless something went wrong), they expected about 200 - 210 rwkw, if i get that i will be extremely happy. Im aiming for anything over 185rwkw, im on the hunt for injectors and z32 afm and will retune once i aqquire them. Ill post later about what power i got.

Well not quite the 200+ they thought it would get but still.. 193.3rwkw on 14psi.. Thats still pretty impressive on standard afm and injectors and cams.. Will be having another dyno run tomorrow morning on 15psi with better fuel and a mild tweak of the power fc and see what it gets then.. I'd like to see a dyno chart showing over 200..

That's a pretty good result with stock AFM/injectors. How was the duty cycle % on the injectors?

ohh dangerously high duty cycle

i would've gotten all the gear before i tuned it, waste of time/money tuning it twice in that short time
