So when the car makes boost it gets faster? That sounds pretty normal dude lol

Or do you mean when its already on boost it feels like the torque drops off at redline? if so that is normal, you get a big whack of midrange torque with the stock turbo around 4-6k then the torque drops off by redline as the tiny turbo can't provide any extra air. If you want that feeling to redline you need a bigger turbo.

Lol, trying to think how I can explain this to the best of my knowledge..

Say I take off from the lights in 1st gear, change to 2nd normally, then put the foot down.. It very slowly makes boost because of the t04e and does get faster as it should.. But then when I hit about 10-12 psi, maybe around 5500RPM (still in 2nd) it feels like the turbo is choking and you feel the car die off a little and splutter like it isn't sucking any air at all? (foot still down)

You dont need to bash it. When on boost theres 12 or what ever boodt you're running coming through the silicone hose on your bov pushing down on it to help keep it shut. So as long you've got some spr

Yes it is that easy.....except that you have to be able to bolt it all together once it is welded up. So a little thought during the "design" phase can save you a lot of swearing later. Main point o

Just take the plastic piece out from the vent on the SSQV. Will be much quieter and not make that high pitched whistle. I also couldn't stand the SSQV sound. This worked. Try it.

Sounds like the typical rich/bad spark misfire that so many people get. Go read up on the previous threads eg the 5500rpm misfire thread, it is usually a combination of too rich/bad coils/bad plugs causing a misfire.

It is extremely common and almost certainly your problem.

Yes was tuned at chiptorque... Lol

18psi - 171kws

(I was more of a noob back then :D)

WUT? you can make that kind of power on a RB25 S1 turbo bolted to a RB20DET @ 1bar (tuned of course)

Don't want to get off topic, but, long story short..

Bought car, booked it in for tune straight away lol.. And just went to some

Random tuning place that don't do skylines or anything..

Don't think it was a very good/safe tune.

      RB25DE NEO with Haltech ECU

      By Kinkstaah · Posted

      For fuelling the Haltechs have O2WB fuel controllers. Very useful for helping tuning VE and correcting for *small* mistakes. Of course if your injector/cam/trigger/sensor data is just wrong (or for a GTT which is not a GT) then you will get impossible reactions to things. I am sure you know this already but the reason people don't typically put haltechs (or any Aftermarket ECU) on GT's is because there's practically no real gains to be had - So this knowledge won't be commonplace.

      Can someone tell me if the cracks seen in the rear sway bar bushings in these photo's is unacceptable from a roadworthy point of view?

      Shouldn't need a "base map" for anything other than guidance to ignition tuning. You just need the engine capacity right, the injector size right, and something, almost anything, for a VE map. On an NA engine, fuelling is almost completely a function of load signal & rpm. It should run and drive with a completely flat fuel map. It will be too lean under load, but that's easily fixed. We used to tune all ECUs without any base map. There were no such things (until someone had tuned a near stock engine on one, and then they had a "base map".

      Duncan's V37.......race car?

      By Kinkstaah · Posted

      What did you actually buy/how much did it cost? When I got mine in like.. 2017...? 2019? the aim was to run Torque for gauges via ODB2 and things like Track Addict/Laptimers/Dashcam/Reversecam/Spotify etc. Mine never broke, but I wonder if you've got the same needs (it sounds like it). Cause I liked the idea of being able to do anything with it. That said, yours also cost 3x the cost of what I spent so... food for thought.

      Duncan's V37.......race car?

      By Duncan · Posted

      For me there is a massive difference in manufacturer or big brand crippled android (Sony, Kenwood etc) vs the sort of thing I've installed here, which is basically just a tablet in DIN form factor with open Android, and the other model of course is mirroring - Android Auto/Carplay. I hate the locked down manufacturer and AA options where they decide what apps I'm allowed to install, including the Launcher but also importantly things like Ecutek (for this car) or Real Dash (Stagea) are not supported. Plus those crippled versions tend to be slower due to both overheads and lower spec hardware. On the other hand, when this breaks I'll likely be in trouble for support....but how is that different to owning an Infiniti anyway
