Hi, is there a way to either integrate a channel over time, or to update a value, such that the new value is the old value plus another channel?
For example, t = 0.998s and channel 1 = 10 and channel 2 = 3, then at t = 1.000s, make channel 1 = previous value plus channel 2, ie 10 + 3 so channel 1 reports 13.
There is no integration operation available in ADU, but you can perform it later in Data Master if needed.
Regarding seconds question:
So the new c1 is the c1 value from the previous loop execution plus the c2 value from the previous loop execution.
Thank you for the response. Both questions were aimed at trying to do he same thing, convert a fuel flow (cc/min) into a total fuel flow, ie L for the virtual fuel tank. The Data Master tip is handy, but won’t work in this case.
Think I might have to get an arduino or something to do this, since I can’t see a way to do this via my ECU (Megasquirt 3). Thanks for the help.
Could you send me a log from your ADU with the fuel flow data? I’ll check if it’s even feasible to calculate it on the ADU.
Please check the example project below — I’ve created something that may be useful for you.
In this project, the total fuel in liters is calculated from fuel flow in ml/min * 10.
So, for a value of 10,000, it represents 1 liter per minute.
Please note that the order of numbers and functions in the project tree is important, so do not change it.
Thank you! That’s a really clever way of doing it. I will integrate it and report back!
Could you explain how this works what each parameter does and what is the logic for doing it that way? I want to do something similar in my case the application will be to compare the mass flow from the MAF and the mass flow calculated from MAP and make sure they both stay within certain ratio, if the ratio is too big there will be a boost leak alert, I was thinking I could integrate 5 seconds of flow and compare both values after the 5 seconds compare the values and reset the whole sequence, if at any point the ratio is exceeded the alert gets triggered
