Hello First, I apologize if this is not the correct forum. Let me know and I will move it to the correct one. I'm having a problem with the tachometer on my Skyline R33 with an RB25DET Neo engine. I'll tell you from the beginning. I'll tell you from the beginning. I have the RB25DET Neo engine installed in a Nissan Patrol GU, with a Link G4X control unit specifically for that engine, and I have fitted a Skyline R33 tachograph to the original GU dashboard, but it doesn't work properly. I have the tachometer connected to the positive and negative terminals of the GU panel's wiring, and the signal cable is connected directly to the ECU output pin, but the rpm fluctuates widely. Can anyone tell me if the output signal from an R33 ECU is the same as the output signal from an R34 ECU, or if the voltage and signal type are different? Regards and thanks.

hello The regulator doesn't seem to be punched, so it's probably broken, I'll look for one and try it. I'll look for a nistune distributor and talk to him. Thank you all for the answers and suggestions

ok, I'll talk to the tuner to see the PowerFc. I have also checked the pressure in the injector rail and I have 2.65 bar at idle and with the regulator vacuum tube disconnected 3.40 bar. According to the manual it has to be 2.45 bar at idle and 2.90 bar with the regulator vacuum tube disconnected. I don't know if this variation is enough to determine that the pressure regulator is not working correctly.

The ECUs of rb25det neo are not all compatible with nistune? In this aspect I am very lost. I am in Spain and these "cars and engines" are not very well known here. The td42 was not sold in Spain either...

Hi everyone I understand that this engine in a 4x4 will consume much more fuel than in the original car. The thing is that a colleague has the same car configuration, engine, including the same turbo, wheels, gearbox and differential group and his consumption is 16-17 L/100Km, my consumption is 30L/100KM, that's why is the query here So I understand that for everything to work properly I have to mount an aftermarket ECU and tune it Thank you

hello I have a rb25det neo mounted on a patrol GQ and I have problems with fuel consumption and I don't know where to look for the problem. With 17L I travel 60 km, checking by filling the tank and then refilling. The ECU is stock and turbo with these features Compressor Size: * Inductor diameter: 52.7mm * Extruder diameter: 76.2mm, * A/R: 0.5 Turbine size: * Inductor diameter: 65.2mm * Extruder diameter: 48.2mm * A/R: 0.63 Maximum blowing pressure 0.9 Bar. Front intercooler with dimensions: 550x300x65 mm. I attach a photo with ecutalk with the values at idle. Also comment that I have an AFR watch, it is not connected to the ECU, and with a slight accelerator load and turbo pressure of 0.2 Bar more or less, the AFR measures 13 13.5. If I accelerate fully, the clock measures 10.5 AFR with turbo pressure of 0.9 BAR What things should I look at to know that it is failing. Thank you

hello use is not competitive. It will be used for carts, tracks, etc. Ok, I'll look at the turbos that you told me about. Thank

Hello. I have an rb25det neo engine mounted on a Nissan patrol GQ. What turbo can you recommend knowing that the engine is mounted on a 4x4 and I want a band of use of rpm as wide as possible. The engine will run most of the time in the "middle" rpm zone. Thanks from Spain

Okay The problem is that the signal from the speed meter of the patrol gr gearbox is not the same as the signal from the skyline gearbox. Cheers

Hi yes, i am using rb25det neo ECU. The wiring is correct What I don't have is the speed signal, but I don't know how to get it. How do I get the speed signal for the ECU to "understand" it. Thank you

Greetings to all from Spain I have recalized a swap of a nissan skyline engine, a rb25det neo, in a patrol Gr and the vtc does not work. Someone who has made this swap can provide me with information on how to make the VTC work in the Gr patrol. Greetings and thank you
