Hi all,

for the last 3-4 weeks I have noticed the funny revs everytime I put the gear to neutral.

it only happened when the turbo has kicked in.

It would go from 5 th gear at 2800rpm to (put in neutral) down to 300 and up to the normal 800-1000rpm. :D

I have changed the ACC but it did nothing....

Also my mate's R32 gtst auto always cutout when the engine is hot. Sometimes can't start for 10 minutes. bloody scary to drive when it decided to die in the middle of a busy intersection.

took both car to the mechanic and they have no idea what is wrong with the car.

maybe you guys know....

Please help....

Much appreciated.

P.S I need a service manual for the R32 gtst.

if anyone have a copy please pass one on to me.... :D

Your problem sounds like its caused by the blow off valve. I had the same problem and replaced the turbosmart atmo venting bov with the standard plumb-back and problem solved...

its caused by the already metered air being vented to the atmosphere, but the fuel still being fed in to go with that air, hence causing it to run really rich when you put it into neutral, so basically whats happening is your engine is overfuelling to the point where it bogs down, and sometimes will even stall, 'coz it floods with fuel.

My suggestion: Get a recirculating BOV.... better for the car, and doesn't make the wanky PSSSSSSSSSSSSSHT sound :P

Yeah, I had the exact same problem. My R31 coupe came over with no BOV and if I was on boost and just dipped the clutch the revs would drop right down and the warning lights would start flashing and sometimes stall.

I installed a bosch plumb back BOV and the problem was cured instantly.

      I’d love to find some where that can recover the dashes to look brand new and original. Mine has a very slight bubble, nothing compared to some I’ve seen though

      $170K. I asked one of the guys there as a joke if that price was just for the passenger seat as it was where the price sheet was... he tried really hard to crack a smile 😄 He also mentioned that every single part of the car was inspected and either restored or replaced with a new or as new part, or made from scratch. The interior was incredible, every inch like a new car.

      Time for a modernisation, throw out the AFM, stock O2s, ECU into the e-waste bin. Rip out the cable throttle, IACV, pedal, etc. into the scrap metal bin. DBW, e-throttle, modern ECU, CANbus wideband, and the thing will drive better than when it left the factory.

      I agree, don't go trusting those trims. As I said, first step is to put the logger away, and do the basics in diagnosis.   I spend plenty of time with data loggers. I also spend plenty of time teaching "technicians" why they need to stop using their data loggers, and learn real diagnostics.   The amount of data logs I play with would probably blow most people away. I don't just use it to diagnose. I log raw CAN data too, as a nice chunk of my job is reverse engineering what automotive manufacturers are doing.

      I'm aware, but unless you're actually seeing the voltage the ECU is seeing and you're able to verify the sensors are actually working I find it hard to just trust STFT/LTFT. I will say, logging the ECU comes naturally to me because it's one of the lowest effort methods of diagnosis and I do similar things in my day job all the time. Staring at 20+ charts looking for something that isn't quite right isn't for everyone. NDS1 allows you to log almost everything so that's normally what I do and then sort out the data later.
