A DIC Datalog and questions

Below is a DIC 2-7 datalog.

What is the ign cor (maps) channel and how does it relate to typical IC?

Also i noticed boost setpoint when off boost is now 0 instead of -0.7psi (I'm at about 700ft above sea level). What's the change?

I little more info on Shiv's DIC would be great, as I expected to see some IC reduction in 3rd.

Also I seem to remember other user logs showing more total IC at maybe 3 or 4deg at the same setting of 100% IC. Are there other determinants?

Talking about bog in the other thread, this log seems a little different than past at shift... the retard not as late into the shift... but not sure on this one and have to look at more logs.

Maybe bogfix not enabled? Maybe shiv can chime in. Timing should be reduced at the shift point.

On another note, no knock anywhere!

there's timing retard during shift, just not as deep into the shift like I would think. but i was only curious because of the other thread... i actually think bog is more dependent on your foot and shift timing then anything else.

Yes, no knock... but this is not new to procede. The maps do feel great... i was just expecting more reduction in IC with it being dynamic.

No difference really. We just made some minor changes to barometric compensation. Wont have an effect on anything.

Also, you can ignore the "ign corr (maps)" channel as it doesn't show DIC corrections. Or any other correction for that matter. Just look at "ign corr" instead. It's the actual cumulative correction that you care about. But everything looks fine. And look, a revised ignition advance target. Go figure

Huh?

I can only see two possible data channels in the list that seem to apply:

Ignition trim
Ignition Total Correction Desired.

Is it one of those? cause I have been using ignition correction (maps) as well.

Ignition Correction (maps) represent the ignition correction induced by the static load x rpm table. It doesn't show additional corrections applied after that by the DIC system, bogfix, etc,. So if you want to see what is actually happening in there, log "Ignition Correction" instead. For the sake of clarity, we'll probably just eliminate the Ignition Correction (maps) channel with the next software update.

OK....but I can't seem to find a data channel with that specific name in the list
