I desperately need to borrow a working Hicas computer. My hicas light comes on and my power steering dies when i turn my 33 off and then on again. My hicas wont speak to the scanner so I need to borrow another computer and head back to Synergy so i can find out if I need to buy another computer or weather it's something else in the car messing up. I'm trying to solve this problem instead of just putting a lock bar in and taking the bulb out... which after a lengthy google search seems to be main solution LOL!!!

Please anyone? :)

i have a spare for an r32 gtr but im pretty sure theyre not interchangable with 33's due to 33's being electronic and 32's being hydraulic... tho if you check and find they're the same I can loan it to you

EDIT - If you're running an aftermarket ECU, consult won't talk to hicas as it requires the stock ECU to initialise and translate the signals - if you have the stock ECU, plug it back in and see if the scanner will pick it up

Heya man, hows the 32? I have nfi if its stock ECU or not, I assume it is as the entire car bar exhaust is stock but who knows..

If I can't get this solved I'm getting rid of the 33.. had enough

take it to a specialist like boostworx or wilall who know many ways to get codes out of your vehicle before you throw in the towel. I had a hicas issue that pissed me off for 18 months but when I found out what was wrong (simple boss kit incompatability) it made the research all the worth while.

unscrew the passenger side kick panel on the left side - it will be a max of 5 bolts (3 on a 32)

you'll see your ecu, if it doesnt say nissan then its not stock

hicas is relatively easy to replace with a lock bar, i believe its a couple hundred dollars, but then you need that bar certified to be street legal, and there are many engineers around. I believe rory thompson can certify a lock bar for $500 odd, but don't quote me on it.

If you want to fix your hicas, be prepared to swap individual components. I personally like hicas and was happy to do the work, however a lock bar may well be a better (quicker) solution.

Its all about which direction u want to go. And if that hicas light comes on and doesnt affect your driving ability at all, do what the japanese do - remove the bulb!

Holy crap that is almost a weeks pay just getting it certified. That is way more money than I'm prepared to spend on this car again, especially after being told o2 sensor is dead and that's $165, plus coilpacks might be on the way out as it's almost stalling taking off from lights when it warms up. I just spent $2k getting major service and alarm so there is $0 cash left to spend for a very long time *sigh. Wish I NEVER bought a skyline. My shitty calibra was less trouble than this head case.

Synergy sourced a Hicas for me to try out which is orsum. Just hope it will work as the parts interpreter said he found 5-6 different model numbers lol.. Find out tuesday if it works or not. Here's hoping it does then I will just need to find a Hicas to buy :D Or sell the car.

Aye, skylines are rather expensive but when you get everything working well, the sheer driving pleasure is second to none. Boost in second around a corner and get a big sloppy grin on your mug, then it doesn't hurt the wallet so much.

Theres always a few things to do when you've just bought a skyline. I too have done the major service, replaced o2 sensors and coilpacks, among many many other things, however I don't regret a cent.

If you can't afford it to be certified, then don't worry about it until if/when you get defected - its not a must do thing. Simply get the lock bar fitted, wheels aligned and you'll be done for around the $200 mark (i think, not sure how much lock bars are - theyre not much tho).

    • 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)?
