Adamw Posted June 28, 2021 Report Share Posted June 28, 2021 It is up to you. If you want to do independant dual bank control then you will need two CAN lambdas and 2 sensors. But generally on cars like this that have a reasonably symetrical intake manifold, bank to bank variation wont be extreme so you can still get a decent tune on it with a single lambda.

Adamw Posted June 30, 2021 Report Share Posted June 30, 2021 CAN wiring something like below. Sorry for the amature ms paint work. Obviously you will need to supply Ign switched +12V and ground to both as well. Ducie54 1 Quote Link to comment Share on other sites More sharing options...

Antony Posted July 3, 2021 Author Report Share Posted July 3, 2021 I had the power and ground wired to a relay and the relay to ignition switch 12v Update got them reading but it only reads one at a time Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 3, 2021 Report Share Posted July 3, 2021 All CAN lambdas are shipped programmed as "Lambda 1", so you need to reprogram one of them to be Lambda 2. To do this, switch off ignition and unplug the CAN lambda that is going to stay named Lambda 1, then power up (so only the one you want to reprogram is connected). In PC Link go to CAN setup>CAN Devices>Find devices and it should find the lambda. On that same screen go to the dropdown where it says Lambda 1 and change it to Lambda 2, then click send. You are done. You can then power down, connect up both and both lambda 1 & 2 should be working. Quote Link to comment Share on other sites More sharing options...

Antony Posted July 8, 2021 Author Report Share Posted July 8, 2021 My dashboard is not reading anything, no rpm, no speed, no temp, no gas can this be a problem with the ecu or something else Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 8, 2021 Report Share Posted July 8, 2021 Does it work if you plug the factory ECU back in? Have you got CAN 2 set to 350Z mode? Quote Link to comment Share on other sites More sharing options...
Antony Posted July 8, 2021 Author Report Share Posted July 8, 2021 I haven't tried the stock ecu and i havent set can 2 to anything Quote Link to comment Share on other sites More sharing options...
BushidoPerfomanceTuned Posted November 23, 2023 Report Share Posted November 23, 2023 First of all Hi and sorry to revive the old topic back Adam like i usually do at HPA forums... Ordered a g4x plugin for 350z we are going with a supercharger route what would you reckon to go for single canlamda will do the deed or since with FI dual o2 control will be wiser ? Also from what i understood from the schematic is if going to do two canlambda installation paralel wire the two modules right ? Quote Link to comment Share on other sites More sharing options...
