problems after swap

Recommended Posts

Hello from Russia my dear friends =)

Initially there was a cedric 34 body of the 2nd generation with a motor of vq25dd, I swap a vq30det with a сedric 1 version ... And as we know in the 2nd version the control of the digital bus, and in the first analog, I went the complicated way but nevertheless started the engine. After a long work there was only one mistake, check the engine - "there is no communication with the speed sensor". The podium panel remained with the 2 versions of the cars (digital bus), and all the wiring and ECU with 1 version (analog bus). Because of this error, the automatic machine works in emergency mode. There is no information on EСU pinouts and engine, nothing at all ... Help solve the problem.

sorry for my english =)

nice car!

In Australia, the VQ30DD model is not allowed to be imported from Japan, so most of the english info on them is from New Zealand. There is not much information available. Isn't the Gloria a common import to Russia? I have come across Russian Y34 information on a few forums. http://www.club-nissan.ru/forums/

I thought Y34 ECU pinout was the same as NM35 (VQ30DET vs VQ25DET), but someone who has re-wired a VQ30DET ECU for a S14 build says its not. http://zilvia.net/f/showthread.php?t=492211

  •     Russia is a unique country =)) The concept of supply of a specific model of the car does not exist, we carry everything that has 4 wheels, bypassing all possible laws and customs control. In our market officially Japanese cars with right-hand drive were not delivered and we are taking them through customs.

        Russian forums talked about information on the site vq30det.com but this site was closed ...As far as I know the ECU pins on 33 and 34 differ, tomorrow I will check the scheme that you gave, Thank you.




    The most informative forums on nissan, a lot of information, may come in handy

    Yeah I suspect the 33 and 34 are different. They run the same gearbox and turbo etc just not sure about the throttle setup (basically a dodgy drive-by-wire system)
