With can handle the best power out put, the power fc still has to be tuned by a tuner. other than it being a plug and play unit, it not good for all situation like maxing out z32 afm's and can't run map sensor on some modles.

and it can't use wide band signals to self tune or ajust perameters.

so what is the best power Fc (lots of users) motech (lots of money ) heltech (lots of money)

Well its going to depend on what your going to use it for. The PFC is enough to attend to the needs of a street car. On the plus side there are a lot of people who know how to tune the PFC so you won't be scratching for information or finding someone to tune for you.

Maybe what may be best for you is to see your preffered tuner and ask what he recommends and can work with best. Because at the end of the day, your tune will only be as good as the tuner is.

Mate im gonna close this only because each ECU has been covered - to death

Its soley upto what you want, what your doing, and what your tuner is familiary with.

No point giving someone a tomato is they prefer apples.

Please search in a couple of days, or flick through the first few pages of this section (as there have been a few just in the past few days)

Thanks

    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
