StuM Posted March 19, 2018 Report Share Posted March 19, 2018 Hi, managed to get my car running on the base map, just a couple of issues to sort before I can send it off to the tuner. 1, I've set up the can lambda and turned off the old narrowband output, I've setup the can and it does find the device, I clicked send at 1mb/s and then unplugged the can to cycle the power when told but its not registering and even though I've saved the settings it doesn't seem to store properly. Also just get a red line on the lambda out with a zero, do I need to change anything else? 2. Even though the cooling fan is saying off, it runs constantly, had to unplug it for now.

ClintBHP Posted March 19, 2018 Report Share Posted March 19, 2018 1, please press F4 to save to ECU 2, Try changing the polarity on the Aux Output. Quote Link to comment Share on other sites More sharing options...
StuM Posted March 19, 2018 Author Report Share Posted March 19, 2018 I have saved to the ECU but it still doesn’t seem to save, on the runtime values I get all green apart from the bottom 2 and green with 3 lines red with ignition off!

Note you shouldnt need to "send" anything to the CAN Lambda, this function is only used if you want to change the bit rate or device ID for that sensor. As soon as it finds the device you just click apply/ok then do a store and it should be away. Attach your map and I will have a quick look that no other setting is preventing it from working.

GregM Posted March 21, 2018 Report Share Posted March 21, 2018 With the cooling fan, there are 3 fans, setting them all to low polarity fixed mine Quote Link to comment Share on other sites More sharing options...
StuM Posted March 21, 2018 Author Report Share Posted March 21, 2018 Thanks Guys, it will take me a day or two due to work to post the map I think but its pretty much the base map with the narrowband input set to off and lambda set to wideband.

StuM Posted March 24, 2018 Author Report Share Posted March 24, 2018 I've not managed to upload the map but I had a look at the Lambda settings under Lamda 1 and it gets to the Lambda Calibrating then throws fault code 2 which says internal error and about every 5 seconds it throws code 26 which is the battery under voltage so I'll have to have another look at the power supply but could the power supply also cause the 2 fault code the internal error?

Adamw Posted March 25, 2018 Report Share Posted March 25, 2018 Yes, most likely I would say power supply. Make sure the wires and power source/fuse/relay etc is capable of 8A. I would also suggest you avoid really noisy power sources such as the idle valve or ignition coils +12v as we have seen that upset them also.

StuM Posted March 25, 2018 Author Report Share Posted March 25, 2018 I’ll look at the power supply again but it’s definitely capable of 8a, I’ve routed the can cables, shielded twisted pair around the engine bay away from ignition wires etc, I have noticed that the can doesn’t save, ie every time I switch it on I have to set up the can again even though it was found and saved last time?

Adamw Posted March 26, 2018 Report Share Posted March 26, 2018 If you are getting lambda status and errors reported in the runtimes then your CAN set up must be ok. Quote Link to comment Share on other sites More sharing options...
StuM Posted March 26, 2018 Author Report Share Posted March 26, 2018 I've just checked the power supply again and its getting +12v ignition fed? Quote Link to comment Share on other sites More sharing options...
Adamw Posted March 26, 2018 Report Share Posted March 26, 2018 As a test, rig up two new temporary wires direct from the battery. Report back if errors dont go away, if they do then you can re-do your wiring. Quote Link to comment Share on other sites More sharing options...
StuM Posted March 26, 2018 Author Report Share Posted March 26, 2018 Yes that has done it, all green now, just the fan polarity to sort and it can go to the tuner, thanks Adam. Quote Link to comment Share on other sites More sharing options...
