Boost control Aim Error

[rayhall]

I have been setting up boost control and as normal I am confused with the M150 settings.

The boost Aim value in the logger does not relate to the values in the Boost Aim Table.

In this screen shot I have set the table values very high 240 kpa G and the aim shows 112 Kpa G

It looks like a boost limit is in effect, and judging by what I can see in the bottom corner of the screenshot it is due to Coolant Temperature. If you look in the pane labelled "Boost Limits, Warnings and Switches" and the one below that labelled "Channels" you can see the status of the Boost Aim and what might be altering it, which may clear up some confusion.

Bottom Left, am I seeing "coolant Temperature" as the boost cause?

I cannot find any setting reated to boost pressure vs cooolant temparauture.

Hi Ray,

this is a quick table I just generated so I dont expect it to match yours. But this is where you'd find it on your package.

Please note that if this isnt set to 100, it will cause the boost to be limited. I'd recommend going through and changing all the boost limits to 100 where they might be lower, where not desired to be in effect.

Chris,

Thank you set the table values to 100% and all fixed.

No problem Ray! Glad that it's fixed up
