what happens is..

no acceleration..

hear turbo winding..

cant get over 2.5 revs or it starts jolting.. like its getting acceleration then loosing it quickly.

Does it 1/6 times i drive the car..

* When i bought the car it did this. He said it was a wiring problem on the AFM, wich it may be.. cause u play with the wiring and the car cuts off*

Just woundering what else this might be caused from if its not the wiring?

Hmmm.....sounds like limp home mode for a faulty AFM, won't let you rev past 2500rpm. My experience was exactly the same, happened fairly infrequently......at first. I killed mine thanks to the use of some normal silcon for a seal between the the AFM and the airfilter. The silcon was not "sensor safe". I know now better!

Cheers

Is it auto or manual?

Sounds like your has blown a cooler piping. Check all the piping to make sure they haven't popped off, reason its surging above 2500rpm is because it builds boost, but the boost doesn't reach the intake manifold as it leaks out somewhere in the piping, then the car over fuels and start surging.

Thats my theory, check the simple things first.

If its not that, then chack AFM.

EDIT: Just re-read your post, does sound more like the AFM than anything. But check all things to be sure. :P

Try borrowing a friends afm and see if there's any difference. If it's not that, do what abu has suggested. Check piping.

Yep thats a good idea actually!

See if that works, saves you buying one and that not being the problem.

You could probably source a 2nd hand one from the forums for fairly cheap. Will keen an eye on the for sale section. If I see one I will post up the for sale thread link. :P

thanks guys, yeah im pretty sure its the afm, i got a microtech to install when i get a new turbo.. so then i wont need my afm, just waiting on loom for the microtech, $300 is cheapest loom iv found so far... dont want to pay that much :nyaanyaa:

Yeah thats good. I reckon AFMs are more trouble then they are worth.

A MAP sensor would be much more reliable in that sense.

Well thats my personal opinion anyways lol

      R32 gtst speedo out by 10kph

      By -Jimmy- · Posted

      Interesting, I haven't read about the issue with oil getting into the speedo in the cluster before. I'll have to take more notice with mine. The speedo on my R32's when I've run factory diff and tyre size have never been accurate as far as I can remember. The non Type-M GTS-t did come with 15" 5 stud wheels and smaller brakes, but that's less than 5% of them.

      Good to hear the condenser you picked up off my brother worked all good. Do you think there could be an issue with your AC compressor itself or the clutch on it then? I don't know a lot about them so I can't really help but keen to hear what it ends up being. Keep the build thread going man, it's nice to look back on over time.

      This is a story of my life things, I learned eventually (thanks to someone calling me out) that my enthusiasm for discussing and sharing ideas that it came across as arrogance and I'm like... WTF?!    One thing I'm pretty sure I justifiably pride myself on is knowing that everyone will have things they can teach you, and you're always going to find out that something you think you know turns out wrong - you just don't know what it is until you get there.   Just the bursting enthusiasm that comes with ADHD when you hit something that gives you dopamine dumps can come across like you think everyone else is wrong or don't matter. But yeah, I'm a software engineer by trade and also do tuning in weekends and 100% have long had a reputation for  quickly making connections when resolving problems or forming solutions that I've sometimes had to take people form a long walk from start to end to explain how I ended up where I did when it's seemed "too simple" when I've stated my initial case, and had the "WTF" type reaction when they've realised how much was actually considered haha.   My reward is that I get all the curly problems thrown at me.

      Wives never seem to find things funny. Especially when they're trying to sleep, and you've found the new funniest thing ever. I've never seen someone be able to get try and be cranky with me, while they're holding back fits of laughter... 😛   Also, I tell mine it's payback anyway. She has BiPolar. So the household can get quite emotionally wild at times 😛

      I'm not up to date on the latest, but for basic modifications like pod filter, lower springs etc you can get a modification permit at the time of inspection.  For more serious modifications you will need engineering.  Intercoolers used to fall into the mod permit rule but its been a long while since i looked it up.   Either way you will be able to get it registered, just a case of $300 vs $3k .
