Vince, thanks for the pointer. Just what I was looking for, I think.

I just ordered the bitscope 310 with/USB. I also ordered the logic probe.
Delivery should be in ~2 weeks (priority handling - air was $25 more and
only saves ~7 days). Didn't realize it was made Down Under. That's OK.
Aussies are OK. We had an Aussie unit with us in Korea (7th Inf. Div.).
Swell fellows for the most part.

I like the fact that the software runs under either Linux or Windoze.

Will post my impressions of it when it arrives.

Paul, if things work out timing wise, I could bring it to Mark's hangar.
You
and Mark could get a look at it then. We might even do some good! :)

Good I'll pack my extra Tracy computer and we can use that pressure
sensor to get a handle on the problem. Probably about Friday or Sat
after the start of OSH. I can stop in Denver on my way home.

Sounds like we have a quorum.  I'd arranged for a 'scope from a EAA chapter
member, but if Doc will bring his new toy, then there is no need for it.

I should have the bung by the end of the week & can get it welded in this
weekend -- so we'll have both O2 and EGT after the VAM.

I'll run the system through its new diagnostic modes this weekend to confirm
there is no wiring issue.  I already have new plugs ready to install as
well.  I won't go for a start.

You can go for a start. It won't hurt.
