For the bootload. Do you suggest just using the wires on the pins out of the harness connected or jump them at the soldered point inside the unit?

Whatever is easier, probably the 2 wires on the harness. I don't know if there is a jumper inside. You shouldn't have to solder anything.

Up and running. Albeit, terrible and smokey and gross. But I can connect, get readings and tune. Pretty sure it's a vaccime leak but I will have to figure out where all the white smoke is coming from under the hood now.

The game that keeps playing and one can't win.

Thanks for the help.

Cool man! I wonder if the tune they emailed you was yours? If the tune was done with a much older firmware version, that could be your current issue.
You should be running the latest firmware v. 3.4.4.

Any vacuum leak will make it run poorly.

I have 3.4.4 now. Not sure what update the current tune is on. I will make a copy and play around. I will also run a smoke test for the vacuum. That will give some sense of direction. Onward and upward.

Thanks again.

Right-click CurrentTune,msq that was sent to you. Open with notepad.
The firmware the current tune was generated is in the 4th line:
<versionInfo fileFormat="5.0" firmwareInfo="MS2%2FExtra+3.4.4+release................................>

It will change when you load it into the MS, so look at the one they sent you before you load it.
When you load, it may throw a lot of error messages depending on how old the firmware was.
Anything before 3.4.0 could be a problem.
Usually you can ignore any messages.
