Megasquirt Support Forum (MSEXTRA)

I need some help. I recently had to replace my laptop and now have an issue getting TS to detect a MSPNP2. I am running windows 10 with a USB to RS232 adapter. When I run Portcheck it has absolutely no issue finding the MS. If I go into where you would update the firmware it finds it again. If I load a tune or try to create a new one it will just sit there and scan. I have tried multiple firmware versions for my adapter. I tried a different laptop and it has zero issues connecting. I'm sure it has to be a setting somewhere but I'm not having any luck finding it. Ideas?



TS MS v3.0.16
MSPNP2 v3.3.1

Looks to be an FTDI cable, so that shouldn't be a problem....

Are you saying in TunerStudio's firmware loader it detects it, but on create project it does not? ( it is the same detect?? )


In Mini-Term if you click Open Port and type an S in the top box, do you get a response?

TunerStudio wouldn't make an attempt to access the MS. I went ahead and reinstalled the software last night and it worked great. I saved the comm log before I uninstalled it if you would like to look at it.
