There was a news story in my local paper showing a picture of a 350z that had crashed near the Travel Lodge in Glastonbury, Somerset. Is it anyone on the forum?

Thanks andy10v, I will have a look at the links you provided.

Hi andy10v, I think it will be a while before I would attempt to tune the engine myself. I'd first want to develop a much better understanding of what's involved, how to read and interpret the data and how to change the various settings to achieve different results. Just really need a place to start.

I've recently upgraded to the latest version of the datascan software and yes it does give the fault codes. That's how I was able to determine that the recent issue I had with my zed going into Limp Mode was concerning the Throttle Position Sensor. I had my zed uprevved at Horsham Developments and I was fascinated by the process of plugging it into a laptop and changing the characteristics of different components in such a way that you can see some noticeable gains. My zed is the first car I've ever owned with that ability. All my previous cars were a lot older and didn't have that technology. I'm a bit of a late starter when it comes to cars and I'm learning all the time, picking up bits and pieces here and there and it's something I want to get into more. I would like to learn more about engine tuning, about what settings there are and how to adjust them, etc. I don't know whether it's something I'd get into seriously, but it is something I'd certainly like to learn more about and gain a better understanding of.

I get what your saying Jetpilot. It's not just that though. The thing is, whenever something goes wrong with my car, I immediately take it to the garage and get them to fix it and obviously if that involves running diagnostics, that's something I get charge for in addition to any work needed. I've always been more into styling than performance and the actual mechanics of cars, but I'm getting to a point where I want to increase my knowledge of that side of things. If I can save myself some money by pinpointing a fault and maybe even fixing it myself, then I could start saving myself a lot of money. I'm not looking to become a fully experienced mechanic, I would just like to gain enough knowledge to be in a position where I can be more informed about any problems that do occur.

Hi Jetpilot. I haven't got my own data to hand, but I did find a screenshot online of the dials and have a couple of examples below. Air Flow Dial Reading - 2.2 A/F Base - 100 Injector Reading - 12 Firstly I don't know what measure is being used for these values and I don't know what the values themselves mean. They are probably all okay, but I want to be able to understand what they are telling me and what the tolerances are. I mean say for instance the Air Flow Dial Reading should be within a range of 2.0 to 2.4 for a Nissan 350z and my zed came back with a reading of 2.5. It's only just over, but at the moment I have no idea what the range is and that 2.5 is quite possibly outside that acceptable range. My usual mechanic hooked my zed up to his diagnostic equipment last week as I had a Throttle Position error come up. He looked at the readings and said that the voltage of the sensor is reading okay. But how does he know that? Where did he get that knowledge from. He primarily deals with Fiats and Alfas, yet he knew that the reading of my Nissan was okay. I'm not a mechanic and I never attempt any work on my zed myself as I'm not confident in my own abilities. I've worked in IT for 20 years and data is my thing and I just want to be able understand this data. Thanks.

Thanks SuperStu, that does make sense.

Hi Guys, Recently I had to use my ODB2 connector and Datascan software to check for error codes and while doing so, I started thinking about something I queried a while ago but never really got to the bottom of. The software is great and I especially like the data display which shows all the dials and what readings they are returning. However, the one thing I've never really mastered is being able to interpret what the information being displayed is actually telling me. It looks really cool, but I want to be able to understand the data itself. I want to be able to look at a reading and think, that's a bit high or that's a bit low. But I've got no reference. I don't know what the acceptable ranges/tolerances are supposed to be for each component. I'm not going to mess with any settings. I'll leave that to an expert. I just want to be able to read and understand the information displayed. Thanks.

Thanks GMBallistic. I know some of this may be obvious, but I appreciate all the little pointers. Especially if it helps me improve my preparation, spraying and finishing skills.

Thanks GMBallistic, that's great. The lacquer not hardening properly may have been to do with me being over zealous and putting way too much on. I am using rattle cans as you call them by the way. Couple of things: 1. Is it wise to use the same make of primer, base coat and lacquer? Just wondered if there could be some possibility of a different brand causing an odd reaction when used with another. 2. I currently use the shed to do any spray painting in, as doing it in the house is out. Would it be advisable to do the spraying in the shed and then to maybe bring the parts into the house as I've got no way of regulating the temperature in the shed as there is no power there? Thanks.

Hi All, I had a go at respraying my door switch panels a short time ago and being a complete beginner at these things, it didn't go well. For one, I don't know what happened with the lacquer, but I let it dry for 24 hours, but when I picked up one of the panels, my fingerprints showed up in the lacquer. Plus a day or two later before fitting, I noticed like a bubbling effect along one edge. Fortunately, I have another set of door switch panels so am going to give it another go. But before I do, can anyone offer any helpful tips and advice so that I can maybe get a half decent job done this time? Thanks.

Hi Ceejay29, According to the gauge, the battery charge is fine. I've only had the car 3 years and about a year after having it, the battery was changed anyway. I've got an ODBII connector and am going to hook it up tomorrow and see what fault codes it returns.

Cheers ZMANALEX. Hopefully there will be a fault code which will help diagnose the problem.

I will check the codes out tomorrow and do a reset if I need to. I did wonder if it was maybe the fuel. It was fine when I pulled onto the petrol station forecourt, but it was after I had filled up that the car suddenly threw a wobbly. ** I should add that I have just gone out and restarted the car. The traction control light is now off, but the engine management light is still on. Will it be okay to drive, even in limp mode if I have to get it to a garage?

Have just been out to get some fuel and when I pulled out of the forecourt onto the road, I noticed that I suddenly had no power. The engine light was on as was the Traction control light. Luckily I don't live far away from the petrol station, but was driving at literally 20/30 mph all the way home as the car just wouldn't go any faster. I'm guessing that the car went into limp mode. Any ideas of what it could be? Thanks.

*** SOLD *** I have a gearstick surround and gauges/pods for sale. See image below. The gearstick surround could do with a refurb as it does have some surface marks, but nothing serious. The gauges and pods are in very good condition. Am asking £40.00 for all three items which will include the P & P.

Thanks guys, appreciate the feedback. I shall have a look at the links you provided GMBallistic. Cheers.

Hi All, Does anyone know where I can get hold of the passenger side and driver side door switch panels in a carbon finish to fit a GT4 (2005)? Thanks.

Saves me some money then. Cheers.

Hi All, Just wanted to ask a question regarding the vent below that I found for sale on Ebay. Obviously it will greatly improve the air intake as it will be much more direct but will it make a significant difference to how the car drives/performs. Not really thinking of getting one, but if there was a tangible benefit then maybe I might. Thanks.

Thanks Renegade. Been looking at getting some custom centre caps and just wanted to reference them against the part number of my existing ones.

Just a quick query. Anyone got any idea what the part number is for the centre caps on a 350Z GT4 (2005)? Thanks.

Have been having a clear out and am selling the parts in the image below. All parts have come from a 350Z GT4 (2005). * PRICES REDUCED TO CLEAR * Gearstick Surround (A few marks, but in good condition) - £30.00 Temperature Controls Unit - 20.00 Upper Pods - £22.00 All three items for 70.00, again this will include P & P.

Hi All, I'm hoping someone can help me with this. See the pictures below. Basically I purchased this hub a while ago as I was fitting a new aftermarket momo steering wheel and thought what better way to go than to match it up with a momo hub. The hub arrived not long after I received the steering wheel, so I took it all to my local garage and asked them to fit it. A short time later I received a call asking me to pop over, only to be told that the hub doesn't fit. Basically the aperture I have circled in one of the pictures was too small to fit over the wiring interface. A bit puzzled I took it away and because I wanted to get the job done, I went ahead an ordered a HKB hub instead, which fits perfectly. Thing is, I am a bit puzzled because on the box the momo hub came in, it states quite clearly that it is for a Nissan 350Z. I've checked online recently and this model of momo hub (K3516) is sold as fitting a 350Z. The only thing I do wonder is that I have the GT4 model which has all the controls on the OEM steering wheel, so am thinking maybe the wiring configuration on standard zed models is different, which would allow the Momo hub to fit. Any thoughts? The reason I am asking is that I would like to sell the Momo Hub, but I don't want to list it as being for a Nissan 350Z, if it doesn't actually fit.

Hi All, Just been reading this thread and was wondering. I've already had the uprev mod done to my zed, but is there a case to be made for having it done on a regular basis or is really only necessary when additional mods are made?
