Just had my car back on the dyno, after my latest lot of mods. Was hoping for a few more kw than the 117rwkw that my car got but at least it was a gain. Dyno was run in 3rd gear.

My car seems to running a bit lean through the mid range, so might have to invest in a fuel pressure regulator.

And it definatly looks like I need to get some bigger cams :P or more tuning or something, the power really drops off up the top end.

The next mods I'm looking at is installing an electric fan and installing a bigger throttle body.

Anyway here's my print out

Yeah I thought it was a bit funny that they ran the dyno in 3rd, don't know why they did that??? <_<

So far the mods that have been done are, exhaust 2 1/2", extractors, K&N pod filter with cold air intake, custom 3" intake pipe from the pod to the trottle body, and running an after market ECU (GTS link).

would be interesting to compare your dyno to a dyno dynamics readout with someone who has similar mods.

as i personally think that you should be pushing more power.

shouldn't it should be fine to do it in 3rd gear if they configure the dyno for 3rd? but hmm... 4th....

p.s - did u retain the VVT with the GTS Link?

Eug, Yeah I'm a bit disapointed with the 117rwkw I was hoping for over 120rwkw, but it is at least a step in the right direction.

Yep it's still running the vvt with the link ecu.

Al, when the ecu was installed and tuned earlier this year it was set up with different mods to what I have now, when I changed to the custom intake and added the pod filter it obviously changed all the air/fuel ratios and the car needs to go back in for more tuning to correct this. I have been putting it off untill I have got more of my planned mods done, I have cams, throttle body and a few other bit's to be done before it goes back to the tuners.

The ECU (GTS link) I'm using is most commonly used on turbo skylines.

I'm not familiar with the Apexi power FC, but from what I have heard are better than the link ecu's. I can't see why they couldn't be used on a N/A car, although better to find someone that knows for sure.

      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...
