Nistune would be smarter than any piggyback crap.  The NA ECU should be able to do what you need - doesn't matter that it was auto.  Nistune will actually help you to get rid of codes that the ECU will probably throw from not having the auto's TCU on-line.

If you have to buy injectors, don't buy stock DET injectors.  Buy some brand new Bosch injectors (or similar) from Scotty (or similar).

Any big pump will do.  The 255 is reasonable, but there are newer Walbros that better suit E85, for some future proofing.

If you do use Nistune, grab a Z32 AFM, or an R35 blade AFM and fit that instead.  No point hamstringing yourself with the NA RB25 AFM.

And upgrade the brakes.

And fit an LSD.

I run flex fulltime with no issues, i can check knock and sensors are working and is easy for my tuner to play with.

Does the job for $600.

You mean you run E85 full time.

PowerFC can't even cut power when you're above a particular load point, it can't even cut power when you've exceeded a particular engine water temperature.

I think you need to admit now that it is a pretty basic ECU.

Nistune can do full flex blending (PowerFC cannot), Nistune has basic engine protection (PowerFC will grenade your motor), Nistune you can vary your VCT (PowerFC you cannot), Nistune has launch control (PowerFC does not have), Nistune you can fully map the DC for the boost solenoid (PowerFC you cannot).

So tell why the PowerFC is better? Because of its useless hand controller?

Also, the RB25DE Ecu can't be Nistuned, at least it couldn't back in the day when I had one.

May have changed now as I admittedly hadn't looked into it for several years, but I got the impression that the actual ECU was fairly different hardware wise to the GTT one.

If that's the case GTt ones are dime a dozen, everyone going Halaltech or Link or Motec or ECU Master or Syvecs these days.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      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.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      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)?

      Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
