My car is a 95 and it still ran rich once modified (10:1) so I don't think you can necessarily say all 95's run leaner, perhaps the fuel pumps/injectors on 200rwkw stock ECU cars are not quite flowing enough, could be any reason really.

It's possible that there are a few different firmwares for the 95 range of cars.

You'd need to get hold of a 95 ECU that has been proven to give good power (good a/f ratios).

Then you'd need to burn that to a eprom (for the R33 chip types they are about $90) and give it a try.

ive got a 1995 registerd r33 but its no airbag so its either a 93 or 94.Does a 95 ecu plug in to a 93??ive noticed that the afm are different between the two.If so whats the going rate for a 95 gtst auto ecu.

Also r the igniton maps different on 95's?

I'm pretty sure all the series 1 ECU's are interchangable cause I'm running a 93 ECU in my 95 car. And apparently I've got a Series 1.5 motor !!! It's lacking the ingition module on top of the cam cover - but I'm sure it's just somewhere else :)

      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

      By Murray_Calavera · Posted

      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.
