According to my notes the calcs should be...
2Bar=X*0.781+8
3Bar=X*1.22+2.2

Which it looked like what yours was set as, maybe try the 2bar calc & see what it does.

Should I be using kpa to measure this... I'm starting to think i have a problem with my map sensor as it has read different values from about 30 to 90 with the key on and engine off so it should be just reading atmosphere pressure and variance of that much seems excessive but I don't know for sure

in the screen shots the description says one thing but the equasion (which is what is used) says something completely different.

I'm not sure where you're talking about mate. In the description it has 3Bar =X*1.22+2.2. In the equation it has X*1.22+2.2. Should I only have the 1.22+2.2 in the equation box? I've got dyslexia so sometimes numbers get jumbled up for me. Cheers

Do you have any idea what unit of measurement I should be using with this? I'm using kpa but the maths just doesn't add up to what the actual boost is. In this screen shot I have 175.44 on b10 and if it is kpa and with key on engine off I have values of 30, 33.92, 36.36 and one at 94.92 so im not sure if that was just some random number or something is wrong but I have losts of 30.something logs and a few others just a little higher but that ine at 94 might be something. I live at sea level so I'm confused on why the kpa at sea level in the map is only reading in the 30s and it should be about 100 kpa. If I take 35 kpa from the 175 its adding up to around 20 psi and in this log it was about 14psi on my boost gauge. I know I'm confusing lol so thanks for helping

no idea about kalmaker, sorry. but itll be a scaling factor to match the shape and an offset for alignment with your units of choise.

So basically I need to figure out the correct scaling calculation to get the correct numbers for kpa? I think I have to measure it in kpa because of not reading negative and positive in the same gauge or graph

yep, 2 numbers. one is scaling (the multiplication part) and one is offset (the addition part).
