Guys,

Looking for some advice.

My car did this last week after getting fuel (98)/ It woulnt rev past 2000rpm no matter if you selected any gear/neautral.I Suspected fuel but now I am not sure as its spot on 2000rpm and when you hit that limit it drops down to say 1000rpm and goes back up.

Anyway I went to show my next door neighbour whos a mechanic after it had been sitting for a while (maybe 1/2 hour) as he suspected an air leak but it ran fine a didnt do it at all.

Now that was a week ago and its been fine since then but low & behold it started today.. It started fine and i drove done the shops 10 mins so the car wasnt evenn warm. Stoped in that shop for 15mins & started again for 5 mins in another shop and when I got in again then it started just checked the temp and it got to 68 degrees so not even fully warm

I have cleaned the AFM & connector with contact cleaner as I suspect something along this line but I am by no mean mechanically minded.I am not sure what should happen even if you unplug the AFM while running?

Now the car has the following mods...

Nistune Z32 ECU

Z32 AFM

660 injectors

SS1pu Turbo

Solid turbo inlet piping (made by Scotty) to air box (hopefully see him tonight to resolder AFM plug wires??)

Yellow Jacket coils

Throw some ideas at me please?

Regards,

Darren

Ps:attached a short video of whats happening when just revving the car in neautral

      R34 GTR Speedo Drive , sensor type ?

      By Butters · Posted

      Working through possible solutions of converting my mechanical speedo.    Anyone know what type of speedo sensor the factory r34 gtr getrag has ? what the output is ? I assume its not a VSS and more a voltage like earlier speedo sensors ? Can an ECU read it ?

      I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps

      Can you mount the ATTESA pump in other locations?

      According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car.

      It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.
