AbbeyMS Posted April 22, 2021 Report Share Posted April 22, 2021 Any one got a 350Z HR motor running on a Thunder G4+ yet, I have the throttles all set up , engine is in a Zed still but using a Boomslang patch loom that keeps the stock ECU for canbus duties' any info on trigger offset and cam control would be a great help Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 22, 2021 Report Share Posted April 22, 2021 I will attach a map from a running engine. This was done in an early beta firmware and I think (not 100% sure) that the trigger offset was eventually written into the code. So trigger offset may be zero or 142. Trigger 2 must be connected to LH inlet cam, and RH inlet must be connected to a DI (the RH inlet is also used for quick syncing the trigger). VVT needs to use user defined mode, instructions for setting up offsets etc are in the help file but these should be working in this map.

AbbeyMS Posted April 22, 2021 Author Report Share Posted April 22, 2021 @Adamw when you say LH inlet cam are you talking about Bank 1 ( bank with cylinder 1) drivers side? reason I say is the 350Z DE uses INLET RH which I am told is from when you sit in the car?

Adamw Posted April 22, 2021 Report Share Posted April 22, 2021 If your car is right hand drive then the right hand cam would be drivers side. Quote Link to comment Share on other sites More sharing options...
AbbeyMS Posted April 23, 2021 Author Report Share Posted April 23, 2021 @Adamw thanks for this; So the HR uses a different sensor for the phase sensor than the DE engines ( the Cars you make a PnP ECU for) Just trying to understand the Nissan V6 Motors?

Adamw Posted April 23, 2021 Report Share Posted April 23, 2021 When the engineers are designing a trigger decoder there are many considerations such as factory wiring, difficultly in interpreting the signal, possibilities of errors as cams move due to future machining, chain stretch etc... The HR trigger decoder uses two cams to compliment the crank information for both phase and position to achieve a very quick sync. I believe the crank only needs to rotate a max of 120degs before the ecu has determined engine positon and can fire the correct cylinder. The old VQ35 mode only used one cam and needed up to 360deg to sync. Quote Link to comment Share on other sites More sharing options...

Thanks @Adamwappreciate your time on this will post my map up once I have the car up and running , this car is what I asked about on the tech email , running piggyback with stock ECU (patch loom from Boomslang) as they think the Can bus is different on the Later HR powered cars , we are having issue with temperature/s inputs into the Link due to the piggybacking of the ECU's still.

JOHNVOR Posted April 23, 2021 Report Share Posted April 23, 2021 Hello AbbeyMS and AdamW i am also building a vq35hr. Everything of thunder wiring connects to factory sensors? And at cams and at crank? No need of new trigger wheel? Thank you Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 23, 2021 Report Share Posted April 23, 2021 Yes, you will need all factory sensors for it to work. Quote Link to comment Share on other sites More sharing options...
