  1. Nice and simple ones: Smoothing of the fuel level sensor to prevent intermittant low fuel warnings and give am more stable reading: Parameter A: GP Input Fuel Level Equation: av(a,10) Calculating centre diff speed differential on AWD Parameter A: FL wheel speed Parameter B: FR wheel speed Parameter C: RL Wheel speed Parameter D: RR Wheel speed Equation: ((a+b)/2)-((c+d)/2) The output of that will be km/h, positive values for front wheel spin, negative for rear wheel spin (relative to each other) Calculating Error in GPS speed readout Parameter A: Driving wheel speed Parameter B: Driven wheel speed Parameter C: Longitudinal acceleration Parameter D: Equation: (a-b)/c The output of this hopefully should prove a theory that the error in GPS speed is directly proportional to the acceleration of the car. Just taking some data points from old logs makes this appear to be about 12.5km/h per G of longitudinal acceleration. If I can pin this down to be pretty consistent then I can trim my GPS speed input with the value and make a more accurate driven wheel speed value on my AWD. Basically acceleration supplemented GPS speed. Id like to see if there was a better way of doing this too. Im also looking at doing one to calculate rate of change of coolant pressure to feed into some engine protection for my head gasket, but I haven't yet worked out what I would use as a threshold for that protection to activate as I have never had a head gasket fail yet to collect data from.
  2. I'm doing some wiring upgrades on the race car and thinking about the overall design. At the moment I am using a star point grounding system on my car. Most items are all grounding to the ground plate on the fuse box (Narva 54450BL) for their power grounds. This fuse box then grounds to the battery via the chassis (this is something I want to change and run a direct cable) I have a plug in G4X ecu, which has power grounds to the fuse box. IGN1A Ignition coils, have a power ground to the fuse box, sensor ground for trigger, and a cylinder head ground A couple of other non-sensitive items such as fuel pumps, wipers, tail lights, fuel level sensor etc ground via the chassis. Sensors of course all ground through sensor ground on the ECU. Is this a suitable system to move forwards with? I will make a change to the fuse box so that it connects direct to the battery rather than via the chassis but other than that I'm not sure if anything else should be changed. I do read in a few places that the engine block is the best point for a star point ground, however that would involve making a new chassis loom as well as the engine loom I am about to do. Can any experts in this matter comment?
  3. Im awaiting a new ECU to arrive, its a plug-in G4X which of course uses the xtreme board. At the moment there are no signs of any base maps to suit this ECU. Im quite happy setting up from scratch but the only base maps are for lower spec ECU with less inputs and outputs so are useless. Will I have to wait for the ECU to be delivered before I can do anything, or will there be any base maps (for any plug in variant will be a starting point) available before delivery?
  4. I got a metal body silver one from Noel leeming the other day that worked just fine for real dash. Using it with a Tab S4 but no reason it wouldn't work with windows
  5. Hi Ive got onboard logging set up but something that recently came to mind was accurate total fuel consumed. Is this possible? Id like to extract the data from the log so that I know how much fuel used on each lap of each track etc. Its nice to have that sort of data.
  6. Has anyone found a way of displaying differential fuel pressure? that would be far more useful to me than just fuel pressure itself.
  7. Does anyone know a way of having a fuel level sensor input to the ECU displayed on the Dash? perferably calibrated value. Its easy to get the data into the ECU but I don't know if there is a way of getting RealDash to display it.
