I am swapping a VHR from a 2014 370z into my 06 350z. Everything fits as if it was oem. Engine, transmission, dashboard, and 370z steering column all fit perfectly.
I'm using all of the 370z ECU, VVEL, BCM, and fuse box modules and its electrical harnesses. Gas pedal is from a 370z.
But my biggest problem is I am not getting into ACC mode. My push to start button is stuck in lock mode but with no indication of the lock symbol on my cluster, as my cluster strangely does not work. My push to start bottom lights up and my power socket works but I do not hear any relays clicking. I do have a NATS delete but still nothing. I have not looked if I am getting 12v on my ECU, as my OBD2 plug does not work either.
The only thing I can think of is my dashboard harness was cut by who sold it to me, I believe it is cut as the window connectors. I do not have any 370z body harness, but how can that prevent me from seeing any other power on my navi system or cluster?

I need to know if I am missing a module to give power to my dashboard, and how to get out of lock mode.

(Also not sure if this was the right forum to post under, this is my first post and it's also my last resort option as Idk what could be preventing me into getting to ACC)

 

Welcome, but your first post sounds like another difficult VHR engine swap. It's not the mechanical swap that's the difficulty, it's the electronic architecture differences between the Z33 and Z34. The number of data points used to run the 370Z is far in excess of what it was for the 350Z. It's a complex problem and one I'm glad I didn't step into. You mention that you don't have a full 370Z body/cabin harness, so I'd start there. Most posters who have asked similar questions about doing this conversion have taken some advice, but few have ever come back to update their progress (or lack of it). Maybe you'll be different.

 

I figured out why none of my 370z electronics were working.. Nissan has a safety button for their fuse box while its at the dealer to prevent the battery from dying.
This is all new information to me so of course I wouldn’t have known about it.

The problem now is the car won’t turn off its electronics. I did have a NATS delete on my 1st ecu, and now I have a stock ecu and still the same results.

Im still missing the rest of my body harnesses, which will arrive sometime this week but how can this prevent the entire electrical system from turning off? Is this key related?

Also, sorry for not even introducing myself. Here is my VHR swapped 350z on 57 Nismo Rays (LXZ shown in photo)

 

Wow thats alot of work! I applaud your efforts thus far …

I’ll echo what DK said in that the VHR is a wildly more complex engine and chassis system then the HR and even more-so the DE. So plan on running into many challenges along the way and keep your expectations low as to what will have full functionality. I think you’ll have issues with many modules between the Z33 and Z34 - they are completely different and incompatible systems - the CAN bus protocol is different.

I had a coversation with my tech support rep at Link ECU and one reason they did not pursue a standalone for the 370z / g37 / qs is because of all communication hurdles between the different modules on the car - it was too complicated and I think there was not enough interest to turn a profit. I bet Haltech is the same.

This may get expensive because I dont suspect there will be solid answers to your questions and you will be doing alot of guessing & checking …

so let me ask this - are your keys programed to the VHR/z34 BCM and ECU that they natively came from?

Push buttom start goes - ACC > On > Start? So, not only are you locked out of ACC, but presumable you cannot turn the car ‘ON’ and you cannot start the car??

Is the ECU tuned on ECUTek?

If so, who is your tuner?

You will likely need to re-enable NATS and have your keys programmed to the BCM and ECU just from the get-go … this should be your first step. You will need to have NATS enable before the ECU and BCM will take a key-reprograming. Try to find an independent automotive computer technician. I found a guy here in Denver that has more capability than the dealership, wildly smart, mobile/comes to my place but he is $200+/hr

Start there and get your keys reprogramed and see where you end up
