Request: is it possible to put tracers on the compressor efficiency tables?

[jeffx]

Hello Hondata team, is there any way to put live tracers on the compressor efficiency tables that will track the logged data?

thanks

The axis look incorrect. I can fix that. The air flow can be traced but not the pressure ratio.

[jeffx]

Thank you. While you're correcting that, would it be possible to set it so that we can also edit the indexes?

[Hondata]

I would prefer not to. I have to spend some time finding and tracing all places where the index is used, but it complicates things if there is any correction I need to make in the future. The pressure range is 1 to 4, which is as much as any turbo needs. The mass flow is 0 to 320 g/s, which should be ok.

The compressor efficiency is only really used for calculating the compressor discharge temperature and various protections, so does not make much difference to the operation of the engine.

Thanks. I understand.

another question, I see that this table seems to be defined in two locations in the factory binary (labeled as ChrSet_etaBoostOpt_M and KFETAVD). Does Flashpro manager update both tables? Or is only one of them active?

[Hondata]

Just one of the tables (KFETAVD) as they are different for some reason.

I see a tracer was added on the compressor efficiency table for the latest update. Thank you for adding that. But if this axis is g/s then it's maxing out at only 280 g/s. Were the values supposed to be scaled in the axis? I know before you had indicated that the axis was representing liters/sec, and IIRC, 280 l/s is a little over 340g/s at standard conditions.

[Hondata]

The index is correct - the maximum is about 340 g/s.

Am I missing something? This appears to still be showing a maximum of 280.0? Also, the maximum pressure ratio in the index is 3.25?

I just need clarification
Is the axis grams/sec or liters/sec?????

matters because it can place us in completely different areas of the compressor map.

[jeffx]

as it is, it appears that this is the only portion of the compressor map that we are able to tune. How does the ECU respond when it's reading 380 or 400 g/s air flow at any pressure ratio?

Axis is l/s.
