So sometimes ill go for a drive, then stop turn the car off, come back 30 mins later and when I go to turn the car on it will turn over easily enough put it won't fire, if I push the accelerator then it comes alive but it will literally not fire unless i press the throttle... and this only happens when it's warm, it's running a Power FC and im starting to think whoever tuned it has no f**king clue.. it seems like they haven't haven't even bothered with a coldstart map or anything, just power runs....for 8 PSI...

Take it back to them and get them to fix the tune then? If your not happy and it has a running issue then they should fix it

The tune was done by the previous owner and was done a year or so ago. So wouldn't he have taken it back immediately if he noticed it was sheeeit? coldstart + A/C it just stalls when you take out the clutch, it's miserable to drive in the morning on the way to work haha

Does Nissan have some cold start sensor or relay or something? that could be on it's way out??

How come in post #1 it's a hot start problem, and in post #4 suddenly it's a cold start problem?

because it has both brah. And a tune would also cause hot start/cold start issues. And so would one of the sensors

Depending if it's overfuelling or under fueling when starting

Might be injectors leaking or cranking enrichment in tune once warm needing touch up but these are only guesses

Need to get the car properly diagnosed

I Called a shop to book it in to have a major look over this issue as well as retuning it.. only problem is that they are booked out until after WTAC and I wanted these issues sorted before then so I could drive down... :/ It has Deatschwerks injectors which could not be more than 3 years old so while that is a possibility i highly doubt it..

Am I allowed to name the company to see if anybody has had issues/similar issues with this company or is bad-naming not allowed?

Where are you located? Lots of shops in NSW.

Im in brisbane, There are a fair few up here too but I really only trust this one shop with tuning, I might call some other shops though and see what they say

Do you have a datalogit? If you can get your hands on one. Backup your current tune the reinitalize the ecu. Let it do its cold start setup and then drive the car until its warm and shut it odf and restart it. If issue persists then its hardware at fault.

I had a cold start issue. Car would never start first go. After many people suggesting the water temp sensor, contact cleaner on the afm sensor had the car starting instantly every single time and improved drivability 10 fold.

Try adding more fuel to the cranking table for that particular temperature it's being a little shit to start at.

Also if your injectors are dirty, this would also attribute to starting issues as it's leaner.

Has this developed recently?

Yes but I also bought the car recently but for the first month or so I never noticed it so that's why I'm not 100% on it just being the tune

And I don't have access to one man :(

      Tein Circuit Master- rebuild worth it?

      By QB6SAGR · Posted

      Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻

      Nice car! I’m glad folks in the US have gotten past the FnF and are buying real cool cars like the 260RS I was with a bunch of mates in Portland about a year ago and spotted a green Stagea (just a regular 2.5T AWD) parked about 2 blocks away and they were like “a what?” So I made a bet with them for a round of beers and said “ok one of you run down there and tell me if the steering wheel is on the correct side” 5 mins later the American comes trudging back up the hill and goes “he’s right guys. Ok what beer do you want?”

      Should replace OR drop the tank, give it's good clean. Might be worth replacing that entire fuel level/pump/cradle thing with this: https://frenchysperformancegarage.com/products/fpg-s13-180sx-r32gtst-single-pump-hanger-kit-billet-hat-6-v3-fpg-089?gQT=2
