Default MS3PNP no connection in Tunerstudio

Hi,

I had a working ms3pnp, left it on a non running car since about september. Trying to connect to it now, battery is charged and all gauges and fans power on but tunerstudio (on a new laptop) will not detect the ECU. Anything stupid I might have missed?

I'm having a similar-ish issue right now. I built the engine in my miata and got a new laptop. My old laptop was a HP running windows 10 and the new laptop was a Lenovo running windows 11. I had to mess around with drivers in order to get the two talk to each other, but the old laptop worked perfectly fine. I eventually switch from the old Prolific chipset cable I was using to an FTDI chipset cable and that made them a lot more communicative with each other. But the old cable and laptop had ZERO issue communicating with each other, so I don't know if my new laptop being a Lenovo (known fo low quality usb ports) or windows 11 was the main problem, could be both.

I am using a newer Dell with Windows 11 just fine... I doubt it's anything to do with the USB ports. Most mass market laptops are all using the same (or similar) Intel chipsets on their motherboards. I think your cable was probably the issue. I seem to remember something about the FTDI cable when I first installed my MS and the newer OS may need that now...

I was using the cable that came with the ecu when I bought it, 2 weeks ago I swapped from the prolific chipset cable to an FTDI chipset cable. It’s more consistent when it works, going from working or not working at random with no pattern I could find, to the FTDI cable working perfectly fine the first time I use it each day to then being inconsistent afterwards. So I’m semi confident that the cable isn’t the problem, I’m mostly suspicious of the laptop itself, windows 11 could also be the problem, with the least likely suspect being the ecu. I got a com debug log that is sent, so once I get a response I’ll post an update, could help niketh solve his issue.
