Dave Eastwood (Gadgetman) - Club Secretary 7,792 Posted February 27 Share Posted February 27 It looks like it. The people like me, using pull up resistors are using the stock universal AiM loom that AiM supply with the dashes, I guess, or making their own. Your IVA loom is a special custom loom, that looking at the wiring diagram will have things like resistors, where required, built in, I suspect. Ive not really seen anyone else on here post about having one, I suspect you’ll just have to try it and see. 1 Quote Link to post Share on other sites

So, I'm almost there and got everything on the dash wired in with the exception of the fuel level which has got me a bit confused. Im using the VIL loom Do I simply connect CH1 yellow wire to the loom fuel sender signal wire as am a bit confused as alot of people mention pull up resistors etc and not sure how to go about it using the IVA loom.

On RS3, you have the option of either reading Mv or Ohm's with pullup resistor cal. Which one should I go with. Also, when calibrating the fuel, is it just a matter of adding a litre at a time & recording the value with a multimeter with one probe on the dash earth & the other on the signal wire. Then plot the results into RS3. Quote Link to post Share on other sites
Dave Eastwood (Gadgetman) - Club Secretary 7,792 Posted February 27 Share Posted February 27 You shouldn't need the pull up calculations, as I'm guessing it's already built in.

Dave Eastwood (Gadgetman) - Club Secretary 7,792 Posted February 27 Share Posted February 27 If you connect your lap top to the powered up dash, you can see the actual feedback Voltages, as read by the dash. I normally use these for calibration, then it factors out any losses on the wiring/connections. 1 Quote Link to post Share on other sites

Hugely, plus, you can manually enter Voltages, too, for as yet unconnected senders, so that you can test the programmed logic of your warning lights, triggers etc works as you intend. The live test page is your best friend when it comes to set up testing and configuration. 1 Quote Link to post Share on other sites
Simon Waterfall Syman84 711 Posted February 28 Share Posted February 28 Been a while but, progress. I need to swap some settings in race studio but light at the end of the tunnel It's alive 1 Quote Link to post Share on other sites
Simon Waterfall Syman84 711 Posted April 8 Share Posted April 8 ok so got the wheel speed sensor fitted up last night but no joy on reading speed, looked in RS3 just and my setting were all over the place. does the below look ok now for a 4 pulse on the front wheel using the hub bolt heads for the signal. will hopefully be able to try it out later thanks Quote Link to post Share on other sites
Chris King 5,024 Posted April 8 Share Posted April 8 I had loads of hassle getting this to work - even tried 3 different sensors. Turned out that the pin in the amp connector plug wasn’t quite pushed in all the way! Worth checking. I’ll look at my settings later for you 1 Quote Link to post Share on other sites

Are you using the dedicated speed sensor input? Or an analogue channel? Quote Link to post Share on other sites
Dave Eastwood (Gadgetman) - Club Secretary 7,792 Posted April 8 Share Posted April 8 And re the Hz, this is the sampling frequency, ie how often, per second, speed is being read by the dash, for a speed readout it doesn’t need to be spectacularly high - that’s just tying up system resources. Its always worth setting the sampling rates to be as few as possible, for each individual input, so speed, 20hz should be absolutely fine, an even slightly slower rate would probably look OK, too. However for something like oil pressure, where you want to know the instant any sudden change happens, then keep it at 100hz. Alternatively, sometimes, when you’re logging and analysing inputs later, like say suspension travel and steering wheel movement, you may want to have quite high sample rates at times, to capture very brief issues on the data logs.
