Hi All-

Now that I have my newly-updated EC2 and EM2 back in place, I wanted to wire
in the O2 sensor to enable auto-tuning mode before I try for a startup
again.  The suggested O2 sensor, unfortunately, requires a 18mmx1.5 thread.
A tough tap to find.  Worse, it requires a 16.5mm pre-drill -- even harder
to find.

Anyone have any suggestions on how to get my hands on either/both of these
without spending an arm & a leg?

Magic words are Metric Hand Taps http://www.mcmaster.com/ Cost one arm.

Magic words are Metric Drills http://www.mcmaster.com/ Cost one leg.

Or if worse comes to worse a 41/64th will work.

Also try Enco or Airgas or Rutland Tool and Supply

Don't forget to make a quart vac can to smooth out those intake  pulses.

I'll stop in on my way back or too OSH (Tuesday next week) and help out.
It will help if you have or can rent a scope. We can take the lid off Tracy's computer
and put a scope on the output wire of the pressure sensor. Or we can
buy a pressure sensor and feed it some power and use it to monitor the pressure
pulses. Or I can bring my computer and power it up and connect to that pressure
sensor. We can tee off the pressure hose.
