Megasquirt Support Forum (MSEXTRA)

Hi guys,
I'm new on megasquirt world
I have a kit car with zetec on TB and MS1 ecu

I tried to analyze a data log with megalog I imposed TPS ADC in options and I insert values ​​from 39 to 217 that are my tps adc values but I got the following error:

Set the correct Y axis field frm the `Options` Menu for table highlighting
and VE Analysis to work correctly"

Someone knows how can I fix this?

Thanks

what are you trying to use as the load values, tps and rpm? or map and rpm? the load for y axis is usually set to map(speed density) or tps (alpha-n). and the other axis will be rpm in most cases. Give a little more info about your install.

I'm trying to use tps adc and rpm ,
In my tunerstudio I have set everything to alpha n , tps adc .

In megalog I changed the settings from map ( default) to tps adc but give me the error and nothing works.

attached you can find the MSL and MSQ files

thanks

I just set up MegaLogViewer MS with your files, all seem Ok. There are a couple possible trip up though..
When setting it to TP ADC, it prompts you for the Max and Min ADC value to turn on an underlying calculated field (TP ADC) that represents the ADC value of TP using the percent of TP logged.
In this dialog, the entries are inverted from what one would typically expect.:
Maximum TPS ADC:
Minimum TPS ADC:

Make sure they are entered with the maximum ADC value on top.

If you need to change the value; go to:
Calculated Fields --> Optional Fields 2 --> TP ADC

This calculated field "TP ADC" must be on for this to work. Make sure it is checked.

After entering or changing the ADC values, you need to reload the log.

Thanks for your reply and help,

I'm sure that I insert the parameters in the right place I saw that were inverted.

If I go to calculated fields I see the options in light gray and if I click on tp adc nothing happens.

Is this the Lite edition of MegaLogViewer MS?
Hmm, that would have calculated fields disabled.

It's the free version,

The error is because that?

Probably.

You could make a custom.ini for TunerStudio that will log TP ADC to the log itself.
Put that in a text file named custom.ini and place it in the dir:

[YourTunerStudioProjectFolder]/projectCfg/

Then any logs you capture going forward will already have TP ADC in them.

I'll try to do that,

If the upgrade of the megalo software will solve the problem I'm open also to do the upgrade.

But I would like to be confident that after the upgrade will work.

In your megalog when you open the file and set to tp adc with correct parameters was working fine ?

Code: Select all

[DataLog]
   entry = tpsADC,        "TP ADC",          int,    "%d"

Put that in a text file named custom.ini and place it in the dir:

[YourTunerStudioProjectFolder]/projectCfg/

I made a custom.ini like you told me but nothing has changed

Yep, I used your log and msq, it is tracing fine.

It looks like Windows is messing with your file names.
It added a .txt extension to your file, then hides the .txt so it looks like you have a custom.ini, but really have a custom.ini.txt

To show your true file extensions on windows XP:

- Start Windows Explorer, you can do this by opening up any folder.
- Click Tools, and then click Folder Options.
- Scroll down and then click Folder and search options.
- Click the View tab.
- Scroll down until you notice Hide extensions for known file types, un-check this line by clicking the check box.

Done,
tomorrow it will try if it works.

Another thing, tunerstudio reads the coolant temperature incorrectly.

I think it's a wrong setting of sensor values.

the problem is that in the toos I do not have the coolant sensor calibration option.

What sensors are you using?

By default all is set to use GM sensors. If you have other sensors, it is easy to change with MS2 and MS3, but not so much with MS1.
You need to use EasyTherm on your S19, load that to the ECU.
EasyTherm will also produce a new inc file that you put in the dir:
[YourProjectFolder]/inc/

I'm not sure about the sensor, I bought the car with ms already installed.
The Coolant temperature is needed only for Warm-Up Enrichments?
If only effect the Warm-Up Enrichments i can mange that ...
It is a problem if I keep the sensor reading the incorrect temperature?

I purchased the upgraded version of megalog and tunerstudio,

Now in megalog the tp adc is working but I had to insert the value min0 and max 240 to have the right graphic ,
With tunerstudio tools the value are 39-217 .
Why that ?

Also in the tunerstudio uploaded version I see that there is the possibility to add a new channel , this can solve my problem that I have with the coolant gauge?
