this is my second post about this problem with my car i have had no luck in finding the problem or having some one to find the problem..........its really annoying

if the car is under a little bit of load in a lower gear and i put my foot down and let the boost build up it will hit max boost then go into loop home mode y??

i have had the car at nissan for a diagnostic.........nothing all levels are normal when the car is running good and in loop home mode

i have checked all the cooler pipes all tight

this was happening b4 i had my car modified.........now that it is modded its still doing it even after being tuned on a dyno

any one have any experience with finding what it could be ???

its now booked in at maztech for them to give it a go over.........

i feel like this problem has beaten me

That's usually a crook AFM (switches to limp-home around 2500 rpm). Unless of course you can actually get it to go past the problem.

Alternately, it's a SERIOUS detonation problem, with the ECU doing some serious spark retardation.

had it run on the dyno at maztech......couldnt find any problems with it in limp home mode it made 162kw at all 4 wheels.......boost droped down to 7-8psi

they think it could be the fact that i had the stock boost restrictor taken out of the line and the boost solenoid cant handle the boost........all mixtures are fine...........so WTF..........i swaped itwith another gtr and same thing happens

could it be i need to use a boost controller ???

      Like loud exhausts? You could be a psychopath.

      By GTSBoy · Posted

      Actually, it is probably pretty legit. I mean, it's still woke feminazi bullshit academia, but you would have to agree that it is very likely that there would be a correlation between wanting a loud exhaust and scoring at the unpleasant end of the scales for dark triad personality traits. The fact that they found it didn't correlate with narcissism and only with psychopathy and sadism definitely shows that the loud exhaust thing is more of a "f**k you" than a "look at me", and I reckon that rings pretty close to most of the dickheads who take it to the extreme. Remember, this is correlation with tendency to be closer to one end of a personality trait scale than the other end. Of course someone who is at the literal opposite end of the psychopathy scale is going to be so considerate of others that they wouldn't even think about wanting to upset anyone with a loud exhaust. So the finding isn't that "you are a psychopath". Just that you score more towards that end of the scale than someone who doesn't like loud exhausts (on average, not necessarily even for specific individuals).

      Blitz ER34 at some point hopefully, should be allowed in Gr3 if they do.

      Blue Smoke from exhaust, RB25DE+T

      By MBS206 · Posted

      Stock R33 boost control, with the exhaust, and FMIC done, will boost creep. There is no tuning around it if it is the factory boost solenoid.   If it has an aftermarket electronic boost controller, the settings/mapping can be altered in it.   Oil could be anything as mentioned, however did it ever do it before you did the turbo swap? How much and how often did you drive the car before the swap?   I'm hinging on too much oil supply, or it's not draining properly.   To check, pull the air outlet off the turbo. Is it full of oil? Drop the exhaust at the turbo, does it appears to be oiled/coked? Now pull turbo and check the exhaust manifold, does it appears oiled and coked the same way?   Secondly, the PCV could even be stuffed / not functioning properly and will cause blowing of blue smoke.

      No "could" about it.

      rb20de neo +t conversion - boost pressure sensor needed?

      By GTSBoy · Posted

      Almost any ECU would work, from a 30 yr old PowerFC to a new Motec/Autronic. But presumably you want new middle of the road ECU, meaning that you want a Haltech or a Link, most likely. As to which model though? I dunno. I don't keep track of what they have in their current ranges. You don't want a plug in though, because plug ins can start to cause you the same wiring issues that you have to chase up with your stock ECU/loom swaps when an engine transplant is involved. If you use a Haltech (and presumably a Link) you could put the base map for the engine in and drive it around and not even need to "tune" it. It will work just fine. I can't recommend a tuner without a location (and even then I can't recommend many, being as I never use any tuners except myself and my brother-in-law). And not many tuners are happy to remote tune. Maybe they'd be happier doing it for a basically stock setup that just needs to be demonstrated to be working properly. But even then, not being able to be with the car to see what the hell is going on and sort out the inevitable problems that will result from an engine conversion done by an amateur..... unlikely to be enthusiastic about the job. And if you think that just adding 2 wires for the boost sensor is difficult - you don't want to be trying to install and set up an aftermarket ECU. You're going to have to bite down hard on something with either approach.
