OK. So a bit of an update: I fixed the knock sensor, it turned out to be a broken wire. The speed sensor is still an issue. The engine light comes on and then the TCS and Slip light comes on. If you turn the car off the TCS and Slip light go out when you turn it back on. When I clear it it goes away for a while, then randomly it comes back. Doesnt matter on the type of driving. Also when I plug in my laptop, the speed gauge in Nistune has no reading. The only thing I can find with the same problem is this but it talks about a de-limiter and I am not aware of my car having one. Any help would be appreciated.

Oh, well in that case the dash has a fault. There's integrated circuitry in there to do the speed signal translation (takes in a saw tooth AC voltage from the speed sensor and outputs a 0-5v square wave for the ECU). That stuff would be nigh impossible to repair unless it was a broken track on the dash circuitboard or something equally trivial.

      I know you don't want to hear this comment, but I can't not say it.  I just can't see 200kw being worth the time and effort. Its like guys with NA cars, putting in headers/exhaust/tune for a massive 20% jump in power. Great, the slow car is still slow and you're down $10,000.  My vote is leave it NA or price in a gearbox upgrade and shoot for at least 300KW, preferably 350KW+.  Now you have a NC that will try to kill you from time to time and will be exciting to drive

      How "plug and play" is the Haltech Pro for R33 GTST

      Ah yep. The main message I want to pass on is, try not to get scared of ghosts when thinking about knock/knock detection.  What I mean is, healthy engines make noise. Knock is also noise. Your knock sensor and ECU combo are trying to determine bad noise from good noise based on how loud the noise is. The factory knock sensors and ECU are not good at doing this.  Modern ECU's are pretty decent at it, however I'd still say that you would want to verify that if your ECU says it's knock, that you actually listen to it and confirm that it is correct.  Are you familiar with the plex knock monitor?  https://www.plex-tuning.com/products/plex-knock-monitor-v3/ I expect you're the type of person that would be very keen to play with something like this. It is great knock detection and you can pop some headphones on and listen to what's going on.  Knock that you've deliberately induced in low load low RPM areas is not really putting anything at risk and is a great tuning/learning/verification tool.  I just thought this was worth mentioning based on the way you were talking about setting up a base map and the Haltech base map settings. There are better ways to spend your time then chasing ghosts and worrying about detonation in scenarios that it is crazy unlikely to encounter it.  I was also wondering, what ECU are you planning to get? Will it be long til you pick it up?

      This came quicker than I thought. It ain't even 2025 yet.

      I somehow quoted my post instead of editing it. I regret nothing.

      STOP GOOGLING FAB9 MAKE BORG WARNER EFR KITS FOR THE NC. THEY PACKAGE AN EFR 6758. DO NOTHING ELSE. CAPS INTENTIONAL. THE BEST RESPONSIVE SETUP EXISTS FOR YOUR CAR, AND HAS BEEN PROVEN FOR QUITE SOME TIME NOW. IN B4 "BUT I WANT EVEN MORE RESPONSE, IN A SIMPLER, MORE RELIABLE PACKAGE" WHICH IS A LS.
