Its a strange one Marcus. On the dyno it's at the same rpm every time (7000). It's not a hard cut or a "rpm cut", but a faint miss. The best way to describe it would be three softest rev limiter ever.

In the road however, depending on how cool it is, it may happen earlier. Gtr Sean drove it before we left for the nats and it missed at 5800. Stupid car.

Car is finally booked into Insight on the 19th of April for the ECU, fuel system and sensor wire in plus the tune. Thats the good news. The bad news is that V-cam aint gonna fit with my pistons and ho

Small update.... ITS RUNNING. Fired first go! Smells like burnt dust apparently .

A 9174 would just make the EGP pressure issue worse and in my mind it seems like a bit of a GT RS shit going on. Not that it's horrendously bad (It wouldn't be no twin buttplug pressures), That's NOT

Make sure you get Yavus to check the settings for ignition/dwell etc. It's the only thing (computer) that has been changed....

I was there today. Tried that one too. :(

Didn't you just replace the alternator? Could the new one be playing up?

Not a chance of that ! 20 mins before it came off my car and it was pumping at full power output. She is almost brand new unit and designed for high power GTR's.

It should be boosting electrical output.

Chuck it on Paul and recheck all your earthing.

CDI time !

Naw wouldn't go that route either. I have a 500R on my 'mini-me' version of Paul's and mine has break-down once it's hot. Hard to nail this one down. Just not sure how to get a hotter spark with lots of amps to make it fire reliably.

Was good to see you lay a decent time there Paul. I'm spewing a bit cause I had to drop out of play so soon. Might have been able to give you at least a little run on times.

Is that not more likely coils then? What coils were you driving with the 500r?

Yeah, your issue is a strange one considering you have tried another set of coils and it didn't change anything :(

I reckon the issue might be the ecu, specifically the fact you're running wasted spark... it'll be over working you ignition system IMO

Thing is, it was perfectly fine 9 months ago. It's pretty much a standard setup bar the igniter which has been modified. Joey has three exact same setup and no issues.

Hi paul

How does the car feel with the higher comp and tight squish ?

Feels really grunty. No need to rev it. I would have liked more comp but without custom pistons it wasnt going to happen.

It will be a few weeks before the tune is finished.

paul,

have you whacked another set of working coil packs or an igniter on the car to test yet?

Yep with coils that just did 425 rwkw a few hours before. Changed ignitor box off the same car. Changed plugs. Then I yelled at it!

Fancy trigger wheel all in check?

Doesnt seem to be any issues there man. Nothing on the logs.

I'm sure it's something silly thats been overlooked due to a serious lack of time.

      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...
