  1. Not super fancy, but I use a math block to filter my speed signal with the average function (av). Works really well.

  2. For Lambda 2, unplug the first lambda so that only lambda 2 is connected to the bus, (you dont need to change anything on the main Mode tab - leave only one channel set to Link CAN lambda and ID 950), then go to CAN devices tab, click Find Devices, when it finds the device, change the parameter drop down box to "Lambda 2" and then hit the send button. Press apply, ok, do a store, power everything off. Plug all CAN lambdas back in and re-power up, both should now be identified and working. For power, prefereably they should just be connected to an ign switched source - let the ECU contro

    I cant remember if they need the pull-up on or not, try it and see. Either edge should work equally.

  4. It will need a bottom board revision to resolve this. The bottom board has been unchanged between G4, G4+ and G4x. It is ear marked to be revised in the future.

    It needs to be positioned a couple of mm away from the surface it is detecting. So, looks like you'll need to make up a bracket.

    Yes, I want to start using traction control, so that needs at least 2 speed inputs, so 2 Digital Inputs. It is waterproof, been exposed to a lot of typical English weather, so lots of rain!

    Here's a snip from one of my log files which shows some low speed. The yellow line is from my 4 pulse per revolution, the purple from my prop-diff pickup. As you'll see, as soon as the rear detected movement, so did the front. By 15mph they were both practically identical, despite the rear having nearly 4x the resolution. Whether that's enough for you, I can't say. I decided I wanted more pulses per revolution, so have made modifications to do so. You probably could attach this sensor to the thin metal backing plate, it's fully threaded so you can adjust the depth accordin

    It's 3 wire - 12v power, ground, and signal. This goes into a Digital Input on the ECU. Calibrate it (as per the help file), and have a nice accurate speed. The bracket took me about 15 minutes to fabricate.

    It is really up to you to tune it to acheive what you want. I dont know what type of racing you are doing or anything. Circuit racers often have a non-driven wheel speed based launch strategy. Jet skis and boats often use a timer strategy. Drag racers with big tires will often just have a fixed limit while the clutch or transbrake is engaged. It is better to use a virtual aux to enable it rather than setting it to "always on" as when it is always on your closed loop lambda and knock control will be disabled. A common virtual aux condition may be something like TP>50% and wheel s

    Usually best to have and arming switch or another option is to use a virtual aux. Yes, for speed base launch control this is why non-driven wheel speed is suggested.

    You cant use a GP speed as non driven wheel speed. Change your DI2 function to one of the wheel speeds - say LF wheel speed. The go to the chassis and Body folder, speed sources, and set non driven wheel speed source to LF wheel.

    You download the file, go to the dwell time table, right click, click on 'import/export and then 'import from file' - you then open the file you have just downloaded and it will load in the table for you.

  14. I had time to play with this today. It looks like you can make it work as is. In the ECU's that dont have the serial data stream settings visible In PC link, it seems that the "requested short" data stream method is enabled by default. Realdash is compatible with that. In PC Link set the baud to 57600. In Realdash set the baud the same and set it to "use short datastream". Let me know if it works for you. I tested it on a couple of my test ecu's and it seemed to work.
