Cutting wire 53, put your HICAS into diag mode, Some people have had problems with their HICAS not working properly once the wire has been cut, and some people haven't had any probs at all. I personally would think its a silly idea if your doing a 180km/hr and your HICAS decides to take control over your car ??

BBQ: Have u actually done it or u just heard what other people say? cause i've actually cut the wire and it DOESNT put the hicas into diagnostic mode.

Anyway, HICAS is rubbish, quite annoying really, i agree about the part not wanting the HICAS to start working at 180kph tho!

Check out modyourcar.com.au I got a Pivot speed meter for $152, it removes the 180km limit, displays speed up to 350km/hr and gives you times and terminal speed for 0-100m, 0-200m, 0-300m, and 0-400m.

There are only four wires and it is easy to install, (comes with ecu pinout diagrams for all models). Good value for money i reckon, plus the hicas still works normally.

Yes I have actually done it, I had mine on a switch so when I need to go over 180km/hr on a private road, I would flick the switch. It would give me a HICAS light on my dash though.

Once I turned the switch off, the light would go away.

I though its not safe to be fooling the computer by thinking that somethings wrong when its actually not. So I got a PFC to remove the limit.

From memory.. the stagea's have the ecu wiring of R34, which is different to this wire 53. The only confirmed result I have seen that has worked for the wire 53 is the R33 ecu wiring.

Be on the safe side and get a proper speed limiter cut, not the dodgy wire cutting.

Just my 2c worth.

    • 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.
    • 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...
