Bit logging
Hi Mark,
I know your hard at work on V4 so I'll throw this one out there.
Is there any way to graph bits along with data?
That would be cool to setup so you could see when functions/status changes during logging. Since the data is already there, it would just be mapping to the graph. (i'm going to be annoyed if this is already possible but haven't figured that out yet )
Things like PE/and AE, hiway modes, tcc on/off.
Might help with transitional issues and give some insight to tuning.
Jp

It seemed that when watching things like PE and DFCO flags would be nice to see a bit make a vertical line trace indicating when it came on/off while viewing the strip chart relating to another parameter. (Vss, TPS or MAP)
Saves jumping back and forth trying to find the exact point where the flag changed.
Just something I thought of when trying to locate where HIway mode was coming on/off in an old log.

V5 ?
Is this looking possible for the next rev?
If not I understand, you stated it would not be a simple change.
Just wondering what your outlook on this was.

The customizable CSV export is a lot of work. I've got it on the list for V5, but we'll see how far down the list I get before I decide to kick it out the door. It's still a few months out.
The bit "Graphing" is easy. You can count on this for V5.

I never realized that graphing of a bit was now possible.
Marks explaination here gave me the idea to try it and it works!

Create a "Value" for "Lockup' as one example.
Set the word to be the location in the datastream (In $8D = 0x36)
set low = 0, set high =100
Equation = "(X&01)/01"
From Magnus's Post...
the equation in the ADX Value would be:
"(X & <bitmask>) / <bitmask>"
where <bitmask> is the bitmask of the bit you're interested in, e.g. 0x1, 0x2, 0x4, 0x8, 0x10, 0x20, 0x40, 0x80, etc.
You'll now need to save and create the Lookup Table.
Insert new item...
Call it "BitConvert'
set 0=10, then add 1 = 90 (not 0 or 100 or it goes off screen)
Save.
Edit definition and set the output to go to the lookup table you just made.
Add the graph item to your monitor.
Save and run your log.
A line will now display indicating the status of the bit.
Good examples for uses that I'm planning are:
TCC Lockup, DFCO, AE, PE, Idle condition, Hyway fuel timer on/off,...
Lots of potential for honing in on transitional problems.
Thanks Magnus

Im always going back and forth between monitor and item list frame by frame to see when a bit is set... can't beleive this is probably the only option I've never used or heard of in TP.
