Just wondered if anyone knows much about how it works. Its the stock one - but don`t work in fact never has. There is plenty of boost as the car does 0-60 in 5 to 6 secs. The gauge itself works and the sensor unit that feeds it works as I have had a syringe on it and it goes + and - ok. Am I right in thinking that when engine is idleing gauge should read minus and when boosting should read positive? My gauge just stays in the centre. Have checked vacuum pipes and all the ones I can see seem to be connected ok. Has anyone ever come across this problem? No doubt something very simple but damn annoying when you can`t find it Cheers Mark

On my J spec import, there are two lots of warning lights on the left of the steering wheel and one lot on the right. My question is what do the ones on the right do? In the 4 months I've had the car none have come on. Are they opporational? The drivers handbook give a list of things which have warning lights, but no picture showing where they are. Most of the ones on the left come on, though there are some blank spaces. Please put my mind to rest!

Can any of you shed any light on this one ?? The ambient temp display was showing negative numbers this evening whilst I was out on a run. I can't remember exactly which ones but think it was something like -32 and -86... So whats that all about then ?

My headlamps, sidelights, foglights and rear lights have all suddenly stopped working!!! I checked the fuses in the relay box and they are all intact, the relays are still clicking when I turn the light switch on and off, is there anything else I can check? I have looked at what I think is the fusible connection box at the rear right hand side of the engine bay and these also appear OK. I put a voltmeter across the terminals of the headlamp fuse sockets in the relay box but could not get a reading with the lights switched on. Is there a common fuse somewhere that I have overlooked? I have checked the online manual mentioned in these forums but have not had much luck…

I've got an auto 90 tt auto import still using a kmh speedo, and it was fine and dandy up until recently. when the auto switch is in 'a/t' position, it won't change up into second.If i put the switch in 'hold' its ok. So I foolishly decided to put an autobox additive in with the atf. The result? I now have no overdrive (ie i have to cruise in 3rd gear) . But....if i'm cruising at about 55mph the revs will drop to a normal level if i take my foot off the accelerator for a few seconds. Another side effect is that when i boot it in 'power' mode, power kicks in for a split second then revs really high without accelerating, yet when i floor it out of power mode …

where is the cheapest place to get these callipres and brake disc's.? Richard.

Hi, On the back of my uk 90tt Ive got a dealers name painted on the left of the hatch lip where the nissan emblem would normally be. It looks like it is painted on with thick white paint, feels a little prowd. Any advice on how to remove this, Warm water won't touch it, but a bit reluctant to try thiners or something similar. Anyone have any bright ideas or is it time to get the thiners and a clean cloth out ? Regards Jon.

I need some advice on the noise a gearbox should make! I am getting quite a bit of transmission whine when rolling and when idling there is more noise form the transmission with the clutch disengaged in neutral than with the pedal depressed. My trusty (non zed specialist) garage suggested they consider replacing the gearbox bearings, but I wondered if this was the total source of the problem. Any of you experts have any comments? - Will bearings be worth trying or do I need to think about a complete recon on the box? How hard is it to get down there - any hints on labour times involved would also be much appreciated. Thanks.

Hi, Got the R33 brakes and want to paint them, does anyone know where to get hold of the Brembo Logo to transfer back onto them?

Whilst having the exhaust done yesterday, I noticed that the exhaust heat shield was rusted through where it clamps just below the outlet manifold. Whether because of the new pipe, or because I didnt hear it over the noise made by the old pipes, I dont know, but it was vibrating like a bugger this evening. Question is: Can I just remove it? or should I remove it and lag the pipe? is anything going to melt, ignite etc? Or anything else anyone could suggest?

Hi all, my brother has recently had the clutch replaced on his TT. Before this was done, it was boosting to just under 1 Bar. After having the clutch done, it is now boosting between 7-9 psi. The ecu is giving code 55. The car does feel down on power compared to before. I have a Mkiv Supra N/A and can out accelerate him. On paper his car should waste mine (220bhp vs 300bhp+) WTF is going on ?

Can anyone help , When i'm driving along my suddenly my speedo needle goes right round and off the clock and the chime from my "lights left on" sounds aswell and when i bang on top of the dash above the speedo it returns to the speed i'm actually doing ! ....Does anybody have any ideas wot it could be ?......:confused: :( :confused: :(

Righty ho... following up on my own post (safety boost), I've done an engine diagnostic (how do you get it out of it now ? even taking key out and back in ,and it's still flashing away at me ?) anyway, it's a det sensor disconnected code 34 and a engine temp sensor disconnected code 13 ( might explain why plenum was hotter than the sun... hopefully ok...) so.. where exactly is the plug for the det sensor ? and where is the lead for the temp sensor as these have clearly not been reconnected properly when they replaced clutch/pipes (they had an abortive attempt at removing the plenum, so it's possible summit is not reconnected up there). stu

ok stupid question, but the ttnet site doesn't say whether I'm supposed to short pins 8 and 9 with the engine off or on, ingnition on or off, etc? anybody ? stu

What's the difference between the HKS AFR and the HKS S-AFR apart from £180 ? Also what's the best site for info on electronics, i.e. EVC's & AFR's ? Before I start looking at prices I wouldn't mind reading up on what theses actually do and also what extra features they have. I'm currently looking at these two for the not too distant future but don't; want anything too flash with loads of extras. HKS S-AFR Fuel controller £275.00 HKS EVC Boost Controller £395.00

I'm hearing a clicking sound (3 clicks) about every 15-20 secs, it's coming from under the dash, behind the air con unit. I've tried switching the modes of the air con but no joy. But it does stop when I turn the De-mister on. Problem is, can't use the air con without it doing my head in. Any ideas ?? Occasionaly car cuts out. This happens sometimes when i come to a halt (not too suddenly). Only when i've been driving for a couple of minutes, after it warms up it's fine. Could this be the PTU? Also, has anyone figured out a way to stop people staring, someones going to do their neck some damage soon. Cheers
