Azza27 Posted April 20, 2020 Report Share Posted April 20, 2020 Have purchased a g4x extreme for an LS2 engine. Do i need a can lambda to run a wideband co2 sensor. From what i read and understand i do however other people are saying i dont. The ecu can run it without a can. Is this true Quote Link to comment Share on other sites More sharing options...
Rossobianconero Posted April 21, 2020 Report Share Posted April 21, 2020 you want to read lambda? if so doesnt have to be from a Can device, you can just buy a Aem X series wideband and you use the 0-5V signal, you just wire that correctly to the extreme and you are ready to go.

Azza27 Posted April 21, 2020 Author Report Share Posted April 21, 2020 So your saying yes it does need some form of controller/ module. ie... the sensor cannot be wired directly to the g4x? Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 21, 2020 Report Share Posted April 21, 2020 An Xtreme will need an external controller. It can be a CAN bus type or an analog type. Only the Fury and Thunder ECU's have wideband controllers built-in. Quote Link to comment Share on other sites More sharing options...

Does link still sell analog type contollers, due to the nature of installation the sensor will only be installed for tuning purposes and then removed. Also i was supplied a bosch LSU 4.2 sensor. Is this even compatible with the link can lambda Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 21, 2020 Report Share Posted April 21, 2020 The only option we have is the CAN lambda and that is supplied with a 4.9 sensor, it is not compatible with the LSU4.2. There are plenty of 3rd party options around (both CAN and analog) if the Link one is out of budget. Quote Link to comment Share on other sites More sharing options...
orlando bello Posted April 22, 2020 Report Share Posted April 22, 2020 When install a wide band analog or Can base I won't remove it as you can use the Close loop lambda function. Quote Link to comment Share on other sites More sharing options...
CMSport Posted April 24, 2020 Report Share Posted April 24, 2020 Hey guys I hope I'm not hijacking the thread but, on this note of sending lambda signal over CAN bus, is this a possibility with the ATOM X too? I'm just in the midst of prioritizing inputs with a customer and if we could send lambda over the CAN that will free us up to use a spare analogue input for fuel pressure. Also, if this is the case, how many CAN inputs can it handle? Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 24, 2020 Report Share Posted April 24, 2020 Yes, even the old G4+ can have Lambda input via CAN. As for how many inputs, there is not really a limitation, although you may run out of channels that you can assign to the inputs. But as a rough guide at present you can assign 8 CAN lambdas, 8 generic CAN analog inputs, 8 CAN digital inputs, 8 CAN EGT inputs, then there are a few random dedicated channels such as steering position and antitheft etc. CMSport 1 Quote Link to comment Share on other sites More sharing options...
CMSport Posted May 4, 2020 Report Share Posted May 4, 2020 That's great, thanks Adamw! That adds a whole lot more value to the lower spec range Quote Link to comment Share on other sites More sharing options...
