3bar COS only logging to 255kpa

[BAD BOB]

Basically when logging it will go to 255 kpa and flat line. Not sure if the tune is still following above that point and just not logging above or if it's a issue with the v2 not reading the map correctly. The map is scaled correctly as well.

The PCM's range for reporting the MAP pid is upto 255 kPa.

The COS's Boost VE table ranges upto 285 kPa regardless of what the MAP pid reports.

But this still leaves the range 255-285 kPa hard to tune.

Off the top of my head there is another MAP PID that will read beyond the SAE.MAP 255kPa limit.

Can you recall the pid name by chance?

Is this a limitation of the OS itself or the PCM?

The pid SAE.MAP ranges 0-255 kPa... I believe it's the OS.

Like Ross said, there is another MAP pid, but I don't see it...

No sorry I don't remember.

It is a limitation of the SAE defined PID, not the PCM.

Any update on this? Need to be able to log to the end of the map sensor.

[tirefryin_s10]

Anyone?

Can you log MAP voltage? and scale it yourself with a custom PID?
