I had the "standard" firmware installed. I finished building the ECU finally, and decided that I needed to install the one that Ken recommended for rotary application.

I go to install the file named ms2_extra_us.s19. Installed the bootload jumper, hooked up to computer, powered up, started up the downloader, selected the above mentioned file, started going. Got about 36% done, said I had an error.

I've probably done something simple & stupid. Got any ideas?


this is what it says:


ERROR: Stack pointer out of range, e=0xE3
Elapsed time 8.17 seconds.

 

You have to use the .bat file we put in the firmware zip file to load the firmware. The standard ms2 loader won't work.

Also, the _us.s19 file is for microsquirt.

I didn't know what the difference was. I figured the _us.s19 file was a more recent version or something.

This learning curve is so steep. I'll get it one of these days

Thanks again Ken.

 

Been doing it so long sometimes I forget.

 

Yeah! Got it working great now!! Kind of exciting for a first timer.

When I go to calibrate the afr table though, it doesn't have my wideband listed. I have an NGK powerdex wideband. Which option should I choose? Generic linear WB, DIY WB, etc?
