MS1 Crashes Laptop on Serial Connection
I just finished assembling my first MS v2.2 kit (after building the simulator kit), and although it tested flawlessly during every test step through the assembly, now that it's complete, if I plug in the serial connection to my laptop (with power applied to the ECU), the laptop completely locks up with the only recovery being to hard reboot the system. Tunerstudio need not be running, if the MS is powered/connected, the system hangs. I already took the box apart and checked all my solder joints, and none are sub-par, and none are shorted. Not quite sure where I should start looking next. Thanks in advance.
Re: MS1 Crashes Laptop on Serial Connection
You might have a bad ground loop going into the laptop. Try a grounding wire from your MS to the grounding terminal on your plug strip, and see what happens?

Re: MS1 Crashes Laptop on Serial Connection
Got a couple questions to help troubleshoot this:
1. Does this problem happen only on the car, or also on the Stim?
2. Are you using a USB adapter?
3. When was the last step you were able to connect successfully?
4. What firmware are you running?
Let me know and I'll see what you can check.

Whoops, forgot about this. Busy, busy, busy.
No, I'm using a PCMCIA adapter
During the MAP sensor testing
No idea, I haven't been able to load it to check yet. It was literally finish project, plug in to tool around with it, laptop crashes.
I don't have it on a car yet, still just on the stim.Matt Cramer wrote:Got a couple questions to help troubleshoot this:

Re: MS1 Crashes Laptop on Serial Connection
It was a good old case of an ID:10T error. I took a close look at the megamanual and at the board and discovered *drum roll* that I had install all five transistors backwards. Excuse me while I go bash my head into the wall.

Re: MS1 Crashes Laptop on Serial Connection
Don't worry, we've all made our share of newbie mistakes. At least it's fixed now.
Re: MS1 Crashes Laptop on Serial Connection
Well, it wasn't so much the transistors at fault. I replaced all five of them and it still crashed the laptop. I went and tried it out on my PC (with a built in COM port) and it works fine. I can tool around with the Stim and all except the RPM value work. I suppose this means that PC card is going in the garbage!
