2.5 bar MAP with 3 bar OS, which MAP channel?

[turboffr]

Which MAP channel should I be using in the scanner? I have the 3 bar custom OS installed and I'm using a 2.5 bar MAP. There are a few different MAP channels that are available. Thanks

3 bar. 2 bar will only read up to 210kpa or 15psi boost. If your using a 3bar OS with a 2.5 map thin u will never see past 2.5bar to use the complete 3 bar table. So just log the 2.5map or 3 in the channels and compare to your actual boost gauge.

You need to use the channel that corresponds to the OS you're running.
