Hi from Australia, hey good to be on here we have just purchased a your dyno control unit, we are upgrading a dyno dynamics max 450 chassis dyno, we are wondering will this vac sensor work with the your dyno unit? thanks Paul  https://www.14point7.com/products/boost-vac-sensor

Which DD 450 max is it must be a older analog unit ??? Over 25 us years old?  

 

Try Banggoods " 3 Bar MAP Intake Absolute Air Pressure Sensor " i buy a lot of items of them very goid service and reliable source.

Heaps of sensors on banggoods

This one will work also amongst many other map sensors they sell

3 Bar Manifold Air Pressure Sensor With Wires For VARIOUS GM 12223861

I would love it if we could configure the gauge display on YourDyno like in inHg and PSI display . This is purely my personal preference in unit's that come naturally to me. Not having to convert from other units.

Hi, you can configure the sensors in any unit you like. There is a new functionality now where you enter any two points on the sensor curve with your choice of units.

Ok understand about choosing a particular unit but can we have vacuum in inHg and boost in PSI  on one gauge? As per picture i posted.

You need to choose one unit.

I used one off eBay and took about 10 minutes to get damaged  :(.

What are you doing with a ardunio and 3 bar map sensor ?

Map sensors are very robust surprised you broke it that easy !

How are you powering up the 3 bar map sensor 5 Volts via the ardunio or separate power supply ? 

How are you reading the 0 to 5 volts signal output ?

via Arduino. i can't remember it right now, was the last year i was with Arduino. suddenly was measuring wrong after some minutes, then definitely was broken. indeed i have around here yet.

Maybe something has changed in the software since 2018, but I have a compound gauge working on the MAP input as you describe.

It would be better if the scaling graph would display negative values on the Y axis, but it works regardless.

@admin Jostein, if you're reading this, would it also be possible to display 3 decimal places in the 'input voltage column' for the AUX1-2-3 scaling?
It currently rounds the voltages to one decimal place, but I can see that it is still using all the decimal places I enter when doing the interpolation.

As a test, here I've entered 1.11, 1.12, 1.13, 1.14 and 1.15 volts.  Once refreshed the table then shows 4x 1.1's and the 1.15 as 1.2v, but the graph shows the true values.

Also, the 'load ramp' function doesn't appear to work correctly.
Here I've loaded a previously saved ramp and then clicked the 'edit curve' button..  The graph is correct and shows the newly loaded curve, but the table hasn't been updated.  Pressing the 'ok' button on the 'edit curve' table window makes the curve I'm trying to load disappear and revert back to the old curve.  So it's actually impossible to load a preciously saved curve.
