Math Block Equation help.

[K4Tuning]

Hey all Im having an issue setting up the equation for a math block id like to set up as an EGT average display. I have 4 individual egt sensors in each of my exhaust runners and they are dedicated to GP Temp 1, 2, 3, 4. If I set up my A,B,C,D parameters as my GP Temp 1,2,3,4. I havent been able to set up the equation properly to just get proper average. Iv tried a+b+c+d/4 and that doesnt work. Iv tried using parenthesis around stuff, tried multiplying by .25. I tried using the "av" and then the equation and i havent been able to get it correct. On another note. I think something might be wrong. If I take just one parameter, and designate it as my GP Temp 1, which is my egt sensor 1, and i make the equation something super simple like a+5, my math block output in like 60 off of my actual temp reading. Last night with engine off my egt probe temps were around 90 and my a+5 equation was giving me a value around 35. I can double check some stuff but what would be the proper equation for average of a, b, c, d? and how do i write it correctly so that link knows what I need. Thanks all.

So I 2 things here, a+b+c+d/4 is equivalent to a+b+c+(d/4) because of BEDMAS so use (a+b+c+d)/4. The 2nd thing is that the mathblock is working with the temperature in celsius and at a guess you are working in Fahrenheit so after you have made that average value you will need to do the C to F conversion if you want the math block to be in degrees F.

thankyou for the info, i will try the corrections and see how that does!
