Procede datalogging

Glowin · 11-28-2009, 07:32 PM

Having some issues, and was hoping to post up a few datalogs to get help in diagnosing.

What are the channels that are best to show in the graphs? Any particular order?

I've got these in this order right now:

RPM
Boost
CAN Actual Ignition Advance
CAN DBW Throttle
CAN Knock

How about Ign Cor?
Is the CAN DME Ignition Advance better than Acutal?

Should any be overlaid on others instead of a separate graph? Knock I find is interesting to see overlaid over ignition advance for example, instead of as a graph on its own.

Thanks for the help!

Can anyone give me a hand with this please?

overlay throttle on can dbw throttle. "Throttle" = your foot. "CAN DBW throttle" = what's happening for real. so with both you can tell what's real throttle closure vs. what your foot is doing. Another interesting thing to log is IAT's

Thanks.

How about Air/Fuel Ratio? I think there's a bug with the software though. I add it as a channel, but then if you go back to view the channels, it says Actual Rear O2 Voltage instead. Tried it like 10 times.
