Stock ECR33 RB25DET. Pulls RPM till 5000rpm and it chocks before going up again. What's wrong? One more question, i have the NISMO 300KM speedometer and i'm stuck at a max speed of 220km. What can i do to make it go all the way to 300km?

What mods you running?

Mine has a nice big flat spot at 5000rpm .. slowly getting this sorted. So far:

replace plugs (.8 NGK Coppers)

tape up coilpacks

ECU reset

Running much better after those, and a cheap way to get close to your RB for an afternoon.

re: second question .. give it more right foot? :D

Did a max speed run just now at final gear at around 200km close to 5000rpm. It won't go any further even when i floor it. Interesting when i saw the engine light come on after 2mins of flooring the accelarator and temp rising above 1/2 line. The engine light went off and temp went down when i release the accelarator afterwards.

    • Just to be clear, there were no lights or codes when the hiccups were occurring. Also nothing noticeable in the cars' braking. It brakes fine and the dash is clear. I only made the connection when it did throw a code and suddenly, despite the lights, it felt great again. 
    • Yeah they are sliders and this was in my head before I worked out it was the speed sensor.
    • Ok so we have a smoking gun.  A few weeks ago I had to replace a speed sensor that I'd fit incorrectly. I replaced the sensor and everything was fine with no lights or codes thrown any longer.  When I was doing some more bedding in yesterday I got ABS and traction control lights again and, considering when this happens those things are disabled, the pedal went back to normal with smooth braking and no hiccups.  The codes thrown are for the same speed sensor that I replaced. When I looked at the sensor I took out it looks like the tip of the sensor is damaged. So whatever happened to it, perhaps it has damaged the magnetic ring on the bearing (that I only replaced the other week). I'll get my boroscope in the hole where the sensor goes and see if there is any damage in there. Hopefully just the tip of the sensor is in there and the bearing is fine. 🤞🏻  It's worth noting also that the pedal hiccup happens more often and for longer periods now and totally goes away when the codes are thrown again which happens usually after 5 or so minutes of driving. Love all your help here as usual guys, thanks!
