    VEMS ECU and VEMS gauge

    Does somebody have an idea how to get the two work together?

    I guess it should be not too difficult to tap into the ECU harness and forward WB lambda and EGT numbers to the gauge.

    there is a plug on the ecu to connect it to.

    the rest is in config. pretty sure vems.hu or vems.co.uk has the setup.

    personnally i use the vems with a wb02 sensor and the gauge with an egt and seperate wb02 sensor. i dont integrate. no real reason other than i expect my lazyness.

      Ow, good to know there is a plug I can re-use. I thought it was physically not possible to connected those 2 out of the box, without making some hardware modifications. I will look into it.

        Hi Bram,

        as I mentioned via email, in order for your VEMS ECU to communicate with the VEMS round gauge you need a newer firmware than the one I shipped (you are currently on 1.1.27, 1.1.44 would be what you need to talk to the VEMS round because it adds the 'chirp' on the serial line that the VEMS round picks up). I'd say get your car running on the shipped firmware and if you want help upgrading email me and I'll walk you through it. 1.1.44 has some bugs which is why I didn't install it on your box, there is some newer stuff coming down the firmware pipeline (1.1.5x) that looks very promising though.

            How much costs that external gauge? Does it run with fw 1.1.53 ?

              im ready to install the LCD from VEMS, it is much more convenient and has much more info on there.
              will post photos when done

                I also have that LCD, but I think that its not very useful to check if everything's OK if you're on WOT with 150+km/h

                  you do data logging for that purpose!!!

                  the EGT and wideband is there.It is only a matter of paying attention,i think.

                    Datalogging yes, but if something goes wrong you will not notice that in time. Having an external gauge would always be wisible in background and can be checked for a sec but maybe I'm wrong. Dunno.

                      I also prefer the gauge over that LCD. The LCD is hard to read while driving and the gauge I would use for secure reasons under WOT and such examples. Now if it would work together with the VEMS ECU it would be a winner.

                        I'm playing with some new firmware this week and also have access to vems round. I'll nail down the specific hardware and software config for you. Stay tuned.

                            have you seen how big the LCD is?
                            it is huge actually! about 10cm in length.
                            im going to use it on the top 3 vents and i believe it is big to see the info of lamda.In any case, if that doesnt work, i might plug in the second lamda i have anyway
