hey guys,

i just had my car remapped yesterday using an RB20DE ecu out of an A31 cefiro.

the car feels a little more powerful now (mild mods: exhaust, fmic, turbotech boost) and was just shy of 200kws on the dyno.

a few issues have come up though,

1. when i start my car 2 out of 3 times it will start and then die down and stall.

2. it idles quite high around 1500 rpm cold start, 1000 when warm

3. strangely when i put it into any gear when stationary the revs will increase a few hundred rpm.

4. the exhaust temp/cat light flashes randomly while driving

any advice, opinions or theories will be well appreciated :)

I personally wouldnt have gone to a RB20DE ecu...you do know that your loosing your VCT or whatever its called by doing that....i have heard of people actually going to Z32 ecu's for RB25's remapped...

Talk to Jeff from Speedlab or whoever did the tune for you mate, they would know the car better and prob be able to sort it out for you as well

I had my rb25 remapp from him. i used a r32 chip and the onli thing i had problem with was when the car was cold it would do the same thing, rev at 1500rpm but when its warm its normal at around just under 1000rpm, he said something about i had an external blow off valve. =]

Prob just needs a cold tune as well mate....my mates 33 had a power fc in it and it did exactly the same thing, got it cold tuned and never had that problem...and you would notice that the car literally goes nowhere unless its warmed right up....sucks if you wanna leave in a hurry

      Jacks that fit under GTR lips that can reach the subframe?

      You know how your car rolled through a fence in your last jacking escapade? Scissor jacks increase the likely hood of that sort of thing happening immensely!

      http://calfinn.com.au/product/1500kg-standard-trolley-jack-cj-2t-c/1500kg-standard-trolley-jack-cj-2t-c   I have this and fits under a S3 33 GTR with no issues. Purchased in 2009 and not one issue. It was $950 back then. Not cheap but something so important isn’t worth cheaping out on.

      R32 GTST - 600KW+ RB28/CD009 Build

      Just trying to get my head around this. At 5psi of boost, you turn on your wmi pump, and then you're using a 3000cc injector, to allow flow upto the actual engine, where you have your 6x200cc injectors and a 500cc injector. If the above is correct, what advantage are you obtaining by having the 3000cc injector blocking flow, is this just incase a line breaks between that injector and the motor you can stop flow immediately? Or are the 6x200cc and 500cc less injectors and just spray nozzle?

      Intro/R33 owner

      By f00stx · Posted

      Welcome! New member myself, but I had an R33 back in 2002. Best advice I could give, based on my experience: if you're running the factory turbo, be very conservative with boost. I made the mistake of just fiddling around with the boost controller and cranking the boost for fun, and the end result was my intake pipes popping off frequently from the constant deluge of oil that was being blown into the recirc by the stressed-out turbo, which itself was siphoning oil from the engine and farting it out both sides of its centre bearing (or something to that effect). If I could do it all again, I would have gotten a new turbo and had a tune dialled in professionally and then just left it alone! Funny you mention the metal shavings in the gearbox, as I had the same thing - the probe plug (magnetic drain plug, essentially) would come out caked with shavings. At least it was doing its job. Not sure if that's just sacrificial wear and part of the deal, or if my gearbox was shagged, but I wasn't abusing it. Enjoy the R33 - they're a dying breed, and if they weren't $35k+ on CarSales in Queensland, I might have picked up one of those again, instead of the 370GT I own now (though I'm loving the 370GT, that big 3.7L V6 just hits different).

      Second time Skyline owner (R33 GTS-T and now a V36 370GT)

      Howdy folks. I owned an R33 back in 2002, which was thoroughly beyond my capacity (financially speaking) to maintain/insure, so we parted ways in 2004. Fast forward 21 years (to literally yesterday, in fact) and I'm now the proud owner of a 2007 V36 370GT. I'm happily surprised by how much power the VQ37VHR makes, compared to the RB25DET, considering the latter is turbocharged. I had planned to add a turbo at some point but I'm on the fence about whether I'll even need it (though I do love the sudden onset of extra torque). Any other 370GT owners around the traps, I'd love to hear about your experiences with this car (good and bad).
