How can we log boost?

[Redline Motorsports]

Is there a way to log boost with a 2 bar map sensor? I guess a calc. pid could be made converting Kpa?? Anyone got one done?

But does that show actual boost psi per rpm/kpa

I see you map column and rows make sense but not the data.....

What pid could be used? If the map is rescaled and FS CO can report to 285 Kpa, then somewhere you should be able to extract that data. The PCM knows where it is!

When using EFILive custom operating system #03, the PID {SAE.MAP} should show the full boost range.

my data and log setups are on my work laptop and i dont have it home. i will upload a pic of pids & what my maps look like tomorrow.

I also run COS5 as it was originally tuned by delco.

That would be great!

Hopefully that works.

As you will notice, i log all KPA AFR in the same Map. I did this because if you have a 0-105kpa map and a 105- 255kpa map. when you go over say 105kpa everything in the 0-105kpa map sits in the 105kpa cell's.

Same thing for when your below 105kpa in the 105-255kpa range. I.e the 105kpa range will have a huge amount of cell hits, even though your not actually hitting 105kpa, i.e you could be idling at 55kpa, this would still register in the 105kpa cell. if you tried to auto-ve tune like this it would completely screw your ve tables when you do a paste & multiply.
