I honestly have never uploaded an ini file, I always let TS do it for me.
Every time I update firmware, it prompts me that the firmware version is different in the controller than in TS and would I like for TS to get the correct ini file for the firmware to which I always click yes. It does it for me and I then go to a restore point right before I updated the firmware and I'm done.
According to the instructions http://www.msextra.com/doc/pdf/Megas...ing_Up-3.3.pdf
the only time you insert the ini yourself is when you have beta firmware or TS is outdated. From the manual:
iv. Other / Browse
This method is recommended only if TunerStudio is not able to detect your Megasquirt, or if you are using a
beta version of the firmware.
The firmware on your Megasquirt may have been provided on a disk or downloaded as a .zip file from the
MegaSquirt Engine Management Systems website. If you have downloaded your firmware and haven't done so already extract the
contents of the zip file to a directory of your choice.
Clicking in the box next to “Other / Browse” opens a screen which lets you browse to your firmware folder.
From here you should be able to select the .ini file that you want to use. It is essential that you use the .ini file
that is appropriate to your Megasquirt. There are four .ini files to choose from:
1. megasquirt2.ini – used for MS2.
2. microsquirt.ini – used for Microsquirt.
3. mspnp2.ini – used for the DIYautotune MSPNP2.
4. microsquirt-module.ini – used for the generic Microsquirt Module. (If you have purchased a
proprietary Megasquirt-2 product based on the Microsquirt Module it is worth contacting the
manufacturer to confirm which firmware/ini version you should use).
Select the file that is appropriate to your Megasquirt and then click Next.
I wish I knew what is wrong but I just get the feeling its the loading of the firmware that's messing with you. I hate to sound like some crazy math teacher and may be way off base, but I would say to clear your head, sit down and thoroughly read and wrap your head around the instructions for loading new firmware as it is really the only
difference from when your car ran to now.
The loading firmware instructions start on page 15 of the first link above.
I mentioned MS2/Extra as that is the code your ecu uses. I guess you can call it the operating system. I mention it so you don't try to use MS3 or other code.
