Gtr gauge issues

Hey guys can't find much in search...

I had my engine rebuilt for my 33gtr, and now my speedo reads exactly 1/2 kph and the revs are all sporadic? I've had someone look at it and came up with nothing. If the engine builder accidentally mixed up my gearbox with a stagea awd could the speed sender be the issue? I don't want to fork out a grand to have the same issue? Or could my cluster just be effed?

This is such a random and bizarre problem that it will be very unlikely that you will get a solution across the internet. Nevertheless, a few points deserve to be addressed.

  1. What do you mean "speedo reads exactly 1/2 kph"? Do you mean, that it reads exactly 0.5 km/h, that it reads either 1 or 2 km/h or that it reads exactly half the speed that the car s actually doing?
  2. How and why would your engine builder "accidentally mixed up my gearbox with a stagea awd"? Is there more going on here than you have said? Why would an engine builder be swapping gearboxes?
  3. What do you mean by "fork out a grand to have the same issue"? Particularly when you present it as a question, with a question mark at the end of the sentence. What are you saying?

With respect to later R33 speedo problems, there was a recent thread with a similar problem. Maybe the solution was posted. Search it up.

"could my cluster just be effed?" Maybe. But if you have problems with 2x electronic meters (ie, they both just receive pulsed signals) then.....would you not suspect a wiring plug related problem.

This is a logic problem. Arrange all the data, then apply logic.

If in doubt, take it to an auto electrician. If an auto eleccy cannot fix this in a couple of hours, I will be horrified at him calling himself an auto electrician.

I don't pretend to know much about cars, I just love em. 

Answers to the following 

1. If I'm doing 60kph it reads on the speedo 30kph

2. There was a stagea awd in the shop at the same time as mine was... I don't know if they're visibly identical and if they are are the speed senders the same? Perhaps they had them sitting next to one another and just mixed them up...shit happens. I never said it was a good engine builder. Engine lasted 300kms shit it's self and then they sold up days later...

3. I don't want to spend $1000 on a new/different cluster, only to find out I've got the same issue

Both the WGNC34 and BCNR33 have the FS5R30A as a transmission option. The Autech 260RS version is going to run the same sensor as a BCNR33. The RB25DET version does have a different speed sensor but the RPM/tach issue is unrelated. On R33s the tachometer comes from the ECU.

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.

      Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).

      Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers

      Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.

      Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.
