30mins on a relative stocky to 1.5hrs on a modded example depending on mods.

times are based on comprehensive tune including cruise etc not just the power curve.

I think I read somewhere that the EMU can also remove speed limit cut, boost cut and whatever other fun cut Nissan built into the stock ecu, is this correct and easy to setup? This would be good, eliminating the need for 5 different tiny computers to overcome each issue.

All made the same power or within 1rwkw so it is never a case of whether or not the EMU is capable. These results were the first few shreds of evidence that initially sparked my interest in the product. Mt tuning has shifted from 95% PFC to about 50% PFC 40% EMU and 10% various.

Ill second that. My tunning has varried greatly as well lattely. Used to do Power FC after Power FC. Tunned a blue in an R32 today and the difference is fairly great between the two. The slight lack of fine injector control does make a difference with the blue model but still a good thing.

its prob stated somewhere and missed it so sorry if i have but pretty much what use are saying is if i had both the pfc and EMU they would produce pretty much the same performance and overall tune? by sounds of it can handle bigger turbo/injectors which i thought it couldnt..

iv been looking for 2nd hand pfc and didnt think about these due to didnt know anything but this thread is changing my mind..

has anyone had one tuned at mercury motorsport? as thats where id get it done

thanks for a great thread to open some eyes and get rid of the doubt !!

This ecu sounds like it shall be very popular soon with the pfc gone, trent would you know when/if they will be producing a harness for GT-T?

unfortunately never as there is not enough demand in japan. The R34 GTT plug is unique. Wire in for GTT only.... it aint hard i did a GT to GTT conversion for a autobarn customer not long ago and it was a piece of piss.

NOTE: WGNC34, GTT and series 2 R33 need jumper 8 set to 12v not 5v as they have internal ignitors. GTT also needs ignition adapter 15921500

Trent I was thinking what would really be helpfull

well from noobs point of view is step by step parameter setting for different model skylines

Stuff like the knock sensor etc kinda threw me and still have me scratching my head as to what they should be set to

Hi Trent,

The voltage measured at the coils is 5v for GTT - when setting it at 12v, why wont this fry the coils?

My car completed installation and tuned with ultimate this week and in the process 3 coils were burnt on the top part just below the connectors - with the setting at 5v. Saw your advice too late and only this morning got my tuner to change and he is apprehensive abt setting to 12v so wud like to know the reasoning behind the change to 12v.

Thanks in advance!

does it have the adapter fitted inside the emanage? part number 1521500. i have done about 6 personally and never burnt coils. if you dont fit the adpater it wll burn coils in a matter of 20-30mins.

I tried to take a pic last night of the adapter installed (the one Trent is talking about)

but my ghetto phone camera sucks on close ups

also changed the jumper on #8 to the 12v system

ill reinstall again today and see if my missfire is gone

i hope it is

Adapter was fitted(but need to check if is 1521500) and in addition my tuner also put in resistors for the coils. Originally splitfire coils were on and when tuned initially 3 were burnt and suspect the silicon covers on them were not so tough.

Still on 5v setting coils were changed to stock ones and these have not yet succumbed to heat. All the while intermittent misfirings at idle and low-mid end. So this morning change to 12v and after that no issues with misfiring yet. Wl go drive and monitor this aftern.

Pls adv the mechanics for setting the jumper to 12v when the coils are rated at 5v.

Thanks!

      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

      By Duncan · Posted

      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...
