Default Tuner Studio Volts/AFR

I just got the new tunerstudio, Phil fixed a bug that will let the VE Analyzer work with my ECU!!

However my tables are back to volts instead of AFR. I followed the instructions in Megatune to convert to AFR since I'm using the AEM Wideband but I can't figure out which file to change in TS.

Does anyone know which file I need to find? Also, is the conversion the same code as it was in MT?

So far I've changed the MSExtra format hr_10 file which should work for my ecu but my targets are still in volts.

Thanks

Are you working with an old MSQ or other old files?

I ask because when I loaded TunerStudio, I simply did a fresh install and never touched any of my old MegaTune files. It automatically came up in AFR units, not volts.

There's no need to load an MSQ the first time. Just configure the TS project for your car, connect it to the MS, and it'll automatically download the current configuration.

very cool, I'll try that.

The only thing that worries me is that for AEM linear's the default setting is volts (in megatune and tunerstudio) and my tunes are all in AFR due to doing the msns-extra hack so I could with a value I understand. So I'm scared that when Tunerstudio attempts to pull the info from the ecu it will see the tables in volts but since it's set up for AEM WB it will have problems as it sets the tables for volts.

The file for me was msns-extra.ini but make sure it's the one in your project folder.

Oh, right. (slaps self on forehead.) I'm using an LC-1 these days, not an AEM.

Ok Joe, I followed your advice and now my afr tables are right. I won't know until later how well it will all work out when I get off work and can try a tune.

Thanks!

Really? Well that's damn interesting. Guess my bad advice wasn't so bad.

But yeah, in general, I try to avoid migrating configuration files between different software platforms is there's any way to avoid it. Not just on cars, either. That sort of thing always gets me into trouble with routers as well.

I don't know if it changed the settings file to afr for the WB but if the tables are right (and it reads the gauge right) I see no reason why it wouldn't work.

FRT_Fun: are you sure that's where your msns-extra file is in Tunerstudio? Those instructions worked great for Megatune but I don't have any msns-extra files associated with TS.

However, for Tunerstudio it looks like you want the "maincontroller" file found in [projectfolder]/projectCFG folder

To be honest I don't have TS installed right now, changing tuning laptops ATM, but I thought it used the same file names. maincontroller sounds familiar. If you find a file that has the bit of code I posted just change it like the MS tutorial shows and that is how I got it to work.

EDIT: Ah yes you are right, I was looking at the folder I saved for MT, not TS. I found my TS saved folder and it is indeed maincontroller.ini. If you edit that is should work, thanks for catching that

It looks like TunerStudio will automatically correct the file when loading the ECU info. So no worries there!

Default Same problem in reverse

I have a MSPnP with an LC-1. Using Megatune my AFR table is in volts. TS is in AFR. How do I switch the volts to AFR?

Switch MegaTune to the LC-1 settings via the Configurator. This will change the tables from volts to AFR.

In case someone else comes across this searching, I'm going to bump this up with my results real quick.

I just installed TS on a Win7 comp that hadn't run MT before, so there were no old files to copy over or any of that. For me what worked was copying FRT's line of code (I have an AEM WB) into the maincontroller.ini in the project folder.

I spent a while scratching my head trying to alter the file in "program files x86" before realizing that the project files were saved in "my documents". Hope that helps someone...
