what happens is..

no acceleration..

hear turbo winding..

cant get over 2.5 revs or it starts jolting.. like its getting acceleration then loosing it quickly.

Does it 1/6 times i drive the car..

* When i bought the car it did this. He said it was a wiring problem on the AFM, wich it may be.. cause u play with the wiring and the car cuts off*

Just woundering what else this might be caused from if its not the wiring?

Hmmm.....sounds like limp home mode for a faulty AFM, won't let you rev past 2500rpm. My experience was exactly the same, happened fairly infrequently......at first. I killed mine thanks to the use of some normal silcon for a seal between the the AFM and the airfilter. The silcon was not "sensor safe". I know now better!

Cheers

Is it auto or manual?

Sounds like your has blown a cooler piping. Check all the piping to make sure they haven't popped off, reason its surging above 2500rpm is because it builds boost, but the boost doesn't reach the intake manifold as it leaks out somewhere in the piping, then the car over fuels and start surging.

Thats my theory, check the simple things first.

If its not that, then chack AFM.

EDIT: Just re-read your post, does sound more like the AFM than anything. But check all things to be sure. :P

Try borrowing a friends afm and see if there's any difference. If it's not that, do what abu has suggested. Check piping.

Yep thats a good idea actually!

See if that works, saves you buying one and that not being the problem.

You could probably source a 2nd hand one from the forums for fairly cheap. Will keen an eye on the for sale section. If I see one I will post up the for sale thread link. :P

thanks guys, yeah im pretty sure its the afm, i got a microtech to install when i get a new turbo.. so then i wont need my afm, just waiting on loom for the microtech, $300 is cheapest loom iv found so far... dont want to pay that much :nyaanyaa:

Yeah thats good. I reckon AFMs are more trouble then they are worth.

A MAP sensor would be much more reliable in that sense.

Well thats my personal opinion anyways lol

      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...
