Hey guys done a fair bit of searching on this but have been unsuccessful...

R33 gtst series 2 rb25det

Splitfire packs

Apexi pod

Boost tee

FMIC

Stock turbo

Apexi power fc

So guys just had an apexi power fc installed on the 33 and the idle is rough when warm and cold, the cold start seems like it isn't even initiating on startup, when the clutch is in when coming to a full stop the revs drop dangerously low to about 400rpm and there's flat spots throughout the rev range oh and not to mention when I turned the air con off today on the way to work it stalled and then when I started the engine I had to keep the engine revs up or else the engine would shake and try and stall...

I'm not going to name the tuner as I wouldn't want to give them a bad name all I know is that they apparently didn't have the software on their laptops to suit the latest style of apexi units so instead they used the latest hand controller that came with the unit.

I'm sure a lot of the problems are tuning related and need to be fix via a tune but I would rather not pay to have something fixed because of poor tuning on their behalf.

Will a tuner fix their mistakes at their own costs or what? Because I'll be damned if I'm paying for them to fix it

Cheers

Any good place will fix their caused issues. Provided they dont blame the car

They can't blame the car everything is running that smooth as anything prior to the ECU going in even had the car checked mechanically and it's running sound so the tuning is the culprit

Sounds like they suck. If they didn't have the correct software they shouldn't have done a half arse tune. I would doubt they would be able to fix it to an acceptable level anyway. like polishing a turd!

Do you have an atmo BOV?

Those things dont sound to hard to fix, but with an atmo Bov, you may still get some stalling off throttle issues. Shouldnt stall when turning air con on or off. There are settings to prevent this.

Otherwise it might be a problem with your AAC/ICV. I think you can check something in SW/SENSOR CHECK on the power FC hand controller (if you have one)

Check the plugs, maybe adjust the base idle as well

Cheers for the input but it's the factory BOV to be honest I cannot stand the whoosh sound and would rather block it off....

I'm not going to mess with anything and will leave it down to the tuner to fix once they have done that I'll be off to see good old matty spry and get a real tune done

They gave you the car back running like that? Did they mention anything to you about the car running that way?

When i got my car worked on by my tuner, He got me to drive it and he sat in the passenger seat. Everything was fine and we were both happy.

They didn't test drive the vehicle on road but the car was running just fine before it was tuned

The only thing I noticed was the revs dropping very low when I came to a complete stop but it wasn't until the next day when the vehicle was cold that I noticed every little thing shaking and lumpy and hunting idle and then it got really bad one day and kept stalling

      WGNC34 - floor mats

      By Marek · Posted

      Hi 🙋‍♂️. Just bought my Unicorn but the interior need some minor work so it would match my expectations ;). I noticed it is hard to get used oem floor mats in good condition so i started to dig if there's any chance to buy set of new ones. I found two websites - nengun and amayama and it looks like one can still buy factory new floor mats in Japan, but thers a small issue. Some mats (i assume genuine, oem ones) are marked as G4900 and these are "discontinued". The ones you can buy are marked as G4911 but i have no idea if these are also oem, made by other producer or some lower quality replacements that looks entirely different. Can anyone help? 😃  P.s. there is also some strange indication - 0V005, 0V015 and 0V505. Any idea what does it mean? Would appreciate any help with this 🙏

      Version 1 aluminium airbox is.......not acceptable No pics as I "didn't like the look.....alot" Even after all my "CAD", and measurements, the leg near the fusebox just didn't sit right as it ended up about 10mm long and made the angle of the dangle look wrong, the height was a little short as well, meh, I wasn't that confident that Version 1 was going to be an instant winner I might give Version 2 another go, there's plenty of aluminium at work, but, after having in on and off a few times, and laying in the old OEM airbox without the new pod filter and MAF, there may be an option to modify the OEM air box and still use the Autoexe front cover and filter.... maybe This >  Needs to fit in here, but using the panel, and not the pod, the MAF will need to fit in the airbox though> I'm thinking as the old OEM box and Autoexe cover that is sitting in the shed is just sitting around doing nothing, and they are relatively abundant and cheap to replace if I mess it up and need another, it may well fit with some modifications to how the Autoexe brackets mounts to the rad support, and some dremiling to move it get in there, should give me some more room for activities, as I don't want to move the MAF and affect the tune Sealing the hole it requires to stick it in the air box is simple, a tight fit and some pinch weld will seal it up tight  I am calling this a later problem though

      Ethanol Content Sensor - Always at 11%?

      and it ends up being already priced in as though you're just on 91RON without any ethanol. Car will lose a bit of economy as the short and long term fuel trims bring down the AFR back to stoich or whatever it is for cruise/idle for the engine.

      Oh, you are right. But, in Australia E10 is based on 91RON fuel and ends up being 94RON. Hence it being the cheaper option for economy cars. The more performance oriented cars go for the 98RON fuel that has no ethanol mixed in. The only step up we have left then at some petrol stations is E85.
