So i just finished putting together a ms3x following the guides on trubokitty.com. When i try to load the firmware, the computer doesn't see anything, i also used portcheck to verify the port was open. This leads me to believe its something to do with the ms3. I've disconnected TPS sensor, pulled the 10A fuse and disconnected coils, i'm not sure if there is anything else i'm missing. I will post some pictures to see if anyone can spot any red flags with the assembly, and please forgive my less than stellar soldering skills, i've never done anything like this before so please bare with me
No but i believe i skipped over that because i didn't have a harness wired or the simulator. Is there any voltage checks i can do now to ensure the ms3 is functioning? I plan to start by seeing if there is 12V at any of the harness connections ends to see if there is an issue with the harness. Thanks for the response

This makes diagnosing pretty easy. Especially if you use the USB connection, the connection is coming straight from the daughter card and processor. If the daughter card has the proper voltage and it's not connecting, then it's either a daughter card issue, or a computer port/driver issue. Did your computer install drivers successfully? Are you using an FTDI chip based cable, and do you have the necessary drivers for it (if it didn't automatically install)?

Can i do the checks without removing the daughterboard? I'm using a random cable i found with a printer so i have no idea what it is, i also don't recall the computer installing any drivers when i plugged it in. It did make a sound and showed up in device manager under com3 but when the firmware loader tried to search the port, it couldn't see the ms3.
So i had the harness wired upside down, i managed to load the firmware with no issues, Thanks! i was also wondering for a 1.8 swapped 1990 what basemap should be usedÉ
So i had it connected to tuner studio for a few min but after a power cycle i could no longer connect and was given an offline status which ended up turning into not connected. I can no longer find the ms3 when i search the port :(
