I have found a couple of rb20det ecu pinouts online but they have conflicting information. Does anyone have a definate A31 Rb20det ECU pinout.

Alternately, does anyone know which wire is needed to connect an external 'digital speed measuring device'?

To me it looked like there may be two wires to each pin, +/-. If this is the case, how is it possible to connect the device to the ecu, if the device only has 1 wire available.

Any info would be appreciated, thanks.

Perfect mate exactly what I needed, Yellow/Green it is... however, how do I wire up the sensor?

It has just 1 wire thats needs to attach to the ecu. I wired it up to the Yellow/Green one, but nothing happens, car works fine, speedo etc all work but not the device? Any ideas?

    • That is correct. I'm using a modified ABS ring and a ZF speed sensor on my rear diff for speed input. I'm running a Haltech ecu. 
    • Been busy with the newborn. We originally thought we were going to go for a third, but we're good with two lol. He's starting to actually sleep now so I've had some energy to work on the car. It's been parked away in the garage since late November due to winter.  I went ahead and redid all my head oil drains. I originally had my front and rear head drain going into the same pipe but have since split them up. I also added an Ethanol content sensor to get ready to run E85 this summer. Tossed it on my return line. Sensor sits nicely under my intake manifold.    I also have a lot of parts that came in for my rear end. I'll be swapping over to a 3.3 final drive and doing the GK teck anti squat mod. While the rear subframe is off, I'll also change every bushing. We're planning on buying another house soon with the condition that I get at a minimum a 2 door garage, so I'll wait to have more room for this. Now onto the strange things that recently happened... After changing the lower rad hose (It had been sitting in my cabinet for well over a year and was the last hose I had to replace), I let the car idle in the garage to bleed my coolant. After running for a few minutes, it started missing. Got much worst within a minute or two and then stalled and would not restart. My crank sensor decided to crap itself. No damage, no explanation, just died. I went ahead and replaced it with another ZF sensor but the heavier duty stainless model with a shield. Tossed that in and started right up. Has anyone else seen this? I hate when things fail without cause. Luckily this was a blessing in disguise... This lead me to recheck my timing. It seems I may have had a beer or two the last time I had set my TDC angle as I was off exactly 5 degrees... I miscounted a line haha. I was running 5 degrees less then commanded. It's a little embarrassing but helps explain why my dyno operator seemed to think I should be making more then 478rwkws.        
    • Sharing results from recent Liberty Walk R35 GTR, since they are still considered as somesort of a V36 Skyline. We do them turbos too. This are high flowed SS-1 models with ball bearing conversion done.  Car have managed to pull 485awkws @ 20Psi so far pushing limitations of factory built engine. The build list for R35 GTR enthusiasts as follow : HyperGear high flowed stock turbos in SS1 (G25-660 specs) Custom titanium intake pipes. Vspec performance titanium front pipes. Vspec performance 4" titanium exhaust. Upgrade fuel pumps. 1200cc injectors. Ignition coilpacks Hks intake plenum. Hks intercooler piping. Greddy intercooler. Greddy bovs. Top-secret coolant reservoir. Emtron ecu. Straight E85. Built gear box.  
    • Nah no bearings, just slip fit.  Would be a reasonably challenging but not impossible job to modify it to run bearings but I'm hoping that's not necessary as I may have well built one myself if I end up spending hours modifying it!
    • Brumbys with good shells are bloody expensive, I've looked at 2 "cheaper" cars, and walked away from both,  plus after some research spare parts are fairly sparce I'm starting to think that I missed the boat on finding a clean one that is straight (ish) and without alot rust I'm starting to think about a old Hilux as panels and other parts are much more available as they sold tens of thousands of them I use to be indecisive but now I'm not sure
