One gauge with two scales.

ok - so here's what i did.
for each gauge type i added a lower and upper "breakpoint" and an associated lower and upper "multiplier". e.g. using a map gauge, you could set the lower breakpoint to 0 and the multiplier to 2.036254 so that if the map goes below 0 psi (i.e. goes into vacuum) then the gauge will multiply the ecu value by 2.036254 and display that value instead. i.e. -10 psi would display as -20.36. the tick mark values will also change.
will this work?

That's exactly what I was talking about, thank you!

been working on an AFR gauge display for logging. here is a short, crude video i took of it in action. i included the gauge in the latest version i posted tonight but it really should be considered a beta version. also, you really need to wait until rob updates all the scanner settings in the asm files before you try it. but, if u can't wait, i can help you get it set up to try out.

What do I need to do to the scanner setup?Originally Posted by wowzer
set the maximum pulsewidth to 131070 in the ecu max field for the pulsewidth ram location. check your email.

Is this vid running with wide or narrow band input?
No input at all. It's showing you the ECU's calculated theoretical A/F. I think Morris' point is to give you a reference to compare a WB signal to for calculating the A/F error and tuning the PEFTBL...
It's essentially the same A/F as the 'A/F setup' in MP Tuner.
yep - this is what i call the "commanded afr" and hopefully will be able to use it to compare to an actual wideband afr to determine fueling error. with that info you should be able to tweak the pumping efficiency table to correct the volumetric efficiency error. still trying to determine if it really is a valid number at this point. also, i noticed this morning when displaying the afr on the graph that the value is whacked out so i need to fix that.
also, the next big step is capturing the actual wideband info into mpscan2 to combine with the ecu output. probably need to get ahold of risen to see how he did it with logworks.

Sometimes it seems like it... My daughter woke up at 2:30 and after I tucked her back in I couldn't get back to sleep, lol...
How do I post a log file on here for others to view? I compressed it to a .rar file, but when I try to attach it to a post, it isn't available.
Oh and how can you get the MapValue to display vacuum in InHg, or at least in -psi? And an the Charge Temp be displayed in degrees instead of volts?

The charge temp is a problem for the SMEC cals because the output isn't linear with voltage. If you want to 'fudge' it, you can change the scale to 300 to (-200) and it should be kind of close. But, there will be some error in the middle of the scale. That is, if MP Scan likes that type of scale. MP Tuner doesn't like a reverse scale.
Ah, do you have a scale or chart of some sort that we can refer to to convert the Charge Temp voltage into degrees?
I got to datalog 3 runs last night at the track, want to post them for people to look at but don't know how to do so.
The MapValue reads 0-30 in psi, but can't be right, because at idle it is still showing some psi.
Yeah, when I setup the boost, I forgot that Baro is added before it's stored. So I need to fix the scale.
Rob M - send your log file to mterveen@yahoo.com and i'll tweak it for you so it displays the map stuff correctly for now. also it will give me a chance to catch any issues of replaying other users log files. when you save a log file all the "current" graph settings are saved with it so the only way to change settings is to open up the log file (.mpl extension) and manually change some of the numbers in the xml layout. so it can be done. best way is to fix the graph settings up front.
to answer a couple of your questions:
1) Fix the MapValue (long term) - attached is a pic of what you should do to your ram file setup. note the ecu and display min/max settings. also, change the decimal cell value to the precision you want.
2) Fix MapValue precision (short term) and change negative psi to InHg - open up the config file (.mpc extension), click on the map gauge, and set the settings as indicated in the picture. note the "format" field uses the standard formatting methods/characters. also, look at the lowerbreakpoint settings and what i changed to get the InHg setup. (see post 103 also)
I am going to post a newer version today that fixes a potential bug in the graphing stuff as well as the afr stuff i'm still trying to firm up.

i've also added the ability to have a specific format if you want for the breakpoints, so you can set the vacuum side of the gauge to show values in InHg as whole numbers, boost from 0 to 10 with 1 decimal in psi and boost above 10 psi as 2 decimals, or whatever. just didn't like the look of the gauge as shown above for the vacuum side of things.

Thanks, you should have mail now, just sent you my log files.Rob M - send your log file to mterveen@yahoo.com and i'll tweak it for you so it displays the map stuff correctly for now. also it will give me a chance to catch any issues of replaying other users log files. when you save a log file all the "current" graph settings are saved with it so the only way to change settings is to open up the log file (.mpl extension) and manually change some of the numbers in the xml layout. so it can be done. best way is to fix the graph settings up front.

Edit: Tried what you said, but it didn't give me InHg. I have a couple extra Format settings than what is shown in your pic.

Your version was the updated one that had the extra settings for breakpoint units and format.

Here's what I get when I put your settings in:
