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.

I have the mxp with contoured dash profile but I think it would fit fine with a normal dash panel. Depends on the steering wheel aswell as with the iva wheel you couldn't see all of the dash. With a m

Hey fellas, Hope your all having a good weekend. Need some help from some of you AiM guru's. 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.

Thanks Dave :0) will try connecting it straight to the signal feed in that case. 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.

You shouldn't need the pull up calculations, as I'm guessing it's already built in.

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.

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.

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

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

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

I've done this aswell 😳

 

The pins aren't the easiest to push fully home.

 

Are you using the dedicated speed sensor input? Or an analogue channel?

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.
