I suggest you do a search on this forum for "hicas" and you will find out everything you need to know.

The only real way you can test out your hicas system is to get the car data steamed by a consult machine. It's the easiest, simplest way to find the problem.

I had problem with my hicas when I first got my car. The wire from the speedo to the computer had been disconnected meaning lots of things weren't registering with the computer (including the HICAS). There is also another problem with my HICAS being that when the car isn't doing hard turns (as in cornering), just driving along the freeway, my light comes on. It's because the connector in the steering wheel isn't making contact so the computer can't make a connection betwen the sensor and the computer. I found this out by getting the car data streamed. You can either get this done at a Nissan dealer, or a mechanic who has the machine. The only mechanic I know that has one is Gavin Wood Auto Tech who is at Labrador down the coast.

I'd suggest if you don't know alot about skylines or cars in general, take it to a mechanic/dealership that knows what they are doing.

mine comes on when i am on the highway for about 20 mins (usually near the strawberry farm on the m1 heading down the coast). My steering wheel does not sit on dead centre - its at about 11 oclock which really annoyed me at first but i am used to it. I didnt wanna recentre it because i thought that it might screw with the hicas??? How easy is it to recentre?

Very Easy

Just take the horn button out with a screw driver then undo the nut inside with a 19mm socket pull the wheel off (it mey need some force) once its off make sure the cable for the horn is at the top, And make sure your wheel has the hole at the top too.

Then put the wheel back on Straight.

Ok there is a way dot on the bolt and one on the wheel so its easy to centre it.

My problem was that the wheel was not a hicas one so i brought a aftermarket wheel and hicas adaptor.

Hope this helps

Dan

As I said in my post, with my car, the wire from the speedo to computer wasn't connected and there for resulting in the HICAS, ABS, speed sensor (HICAS and ABS use the speed sensor to function) and the speed cut wasn't working. All because of this one wire.

When I had that problem, the light used to come on after a few minutes of driving. Everyone kept telling me to check the power steering fluid but that wasn't the problem.

I have a spare HICAS computer here if you want to check that out. I got it.... "FREE" lets just say :)

      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.

      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...
