I'd say the tuner would be risking it... might be good for the street but what if something happens on the dyno for it to reset/ reengage or anything like that...

As on the dyno it will want to put torque to the front wheels as it thinks the back end is completely "slipping" out at over 150km/h, thats why my tuner will only put my car on without the front shaft to be sure.

Where are you reading these faults from? the attessa computer in the rear of the car has its own little L.E.D on the unit that flashes when there are faults, it wont flash on the cluster like a RWD skyline does, it will only turn the 4WD light on which is basicly telling you to look in the boot at the module and count the flashes there. The series of flashes you are talking about wont output from the unit in the boot. If your reading them from the cluster then its 77 for rear heated oxygen sensor circuit and 43 is Throttle Position Sensor but i dont know what its doing if your reading the flashes from the unit in the boot.

Reading form the ECU in the boot mate, on the very odd acasion the AWD will not come on, or will come on a while after start up, it will buzz and flash likes its priming up then just stay on. its got me stupmed.

p.s i recoreded these codes about 10 times jsut to be sure i was reading them correct, its pain staking.

Your lucky i work for Nissan and had time to look today :thumbsup: . This is the error codes for ALL r33's with 4WD so its legit and i found it in some old book which has more info than the net.

43 = ABS actuator motor , motor relay and circuit

77 = ET-S/ABS control unit ground and circuit

It obiously points to a break somewhere in your circuit so i would check all fuses/relays then conectors then earths and lastly wires or maybe the interal wiring is worn in a moduel/motor just check everying.

i had a problem with my car idling at 1500rpm and my 4WD light came on and my ATTESA ECU flashed 75 for TPS, when ever i used anything electrical and that includes my brake light or headlight or wipers etc etc and i was stumped for 2 years and spent ($6000 COST PRICE!! probably $12000 retail) on work just think i might fix it one day changing things and found the other day it was a earth cable from the starter motor to body just under the black fuse box in the engine bay, it needed a bit of sand paper and tightening. Most likley wiring..........

haha mate thanks for taking time to find that out, aswome info, i thoguht it was my Main ABS so i had that changed ages ago, lucky i got a cheap one, ive taken it to a auto elec, i think i need a specilist nissan auto electrition. any ideas?

    • 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)?
