Easy to say... while the car is undergoing paint and body work and
-nothing- is connected. ;)<br>
<br>
Yea grandpa... please don't tell us again how it was looking at the
fuel pressure gauge that got you to the finish line year before
last. :)<br>
<br>
If I were you, I'd solicit someone like Mike Trusty or Kirby
Schrader to tune your EFI. Not being familiar enough with it
myself, I might end up screwing it up and making you go slow or
grenading an engine.<br>

Tonight was a fairly easy night. The new engine oil and filter
arrived for the Pantera, but the new oil temp gauge doesn't get
here until tomorrow night. I don't want to pull the plugs on the
oil pan until the gauge is here.<br>
<br>
I really liked that Innovate dual oil temp/pressure gauge, it was
kind of slick. The one I ordered is just a plain digital display;
least expensive model I could find. I figure I can always move up
in the future when more sponsors come in to play. :)<br>
<br>
Tonight I did two things, first I installed the O2 sensor in it's
exhaust bung, routed the wires, zip-tied a couple of spots and
hooked it up to the main harness.<br>
<br>
Then I did something I gathered parts for a while ago but never
got to it. Let's take a trip into the Pantera Research Institute
testing lab...<br>
<br>
Some time back I picked up a Hantek 6022BE digital oscilliscope:<img
moz-do-not-send="true" alt="o-scope"
src="cid:part1.09030007.09020300@asajay.com" style="margin-top:
152px;" id="irc_mi" height="244" width="300"><br>
<br>
I then sourced a pickup for the secondary wires of the ignition
system:<br>
<br>
<br>
<br>
<img moz-do-not-send="true" alt="pickup" style="position:
relative; left: 0px; top: -50.5px;"
src="cid:part2.00050706.01090605@asajay.com" class="fullScreen"
height="300" width="300"><br>
<br>
The scope comes with software to actually "see" the scope; a
laptop or tablet computer running Microsoft Windows can host the
software and essentially turn your computer into an oscilloscope.
Here is a basic screenshot of the software in action (just not
from my car):<br>
<img moz-do-not-send="true"
src="cid:part3.08050506.09070507@asajay.com" class="irc_mi"
style="margin-top: 186px;" height="215" width="256"><br>
<br>
I installed the software on a laptop, clamped the secondary wire
pickup to the Coil secondary wire (the big fat one that goes to
the center of the distributor cap), attached the lead to the scope
box and the scope box to the laptop. I attached it to the coil
wire so I could capture all eight cylinders as opposed to say a
timing light you attach to just one cylinder and it pulses the
light only when that cylinder fires.<br>
<br>
All that was left was to fire up the engine. Once I did I made a
few quick adjustments on the scope and I can now see the secondary
wire ignition patterns just like you used to get at the auto
repair shop.<br>
<br>
Pretty cool huh :)<br>
<br>
It's not something to have mounted during the race, but I'm hoping
it will be another valuable tool in tuning the engine -before- we
go to the race. I can now monitor air/fuel ratio and ignition
patterns. I didn't capture a screenshot tonight but will later.
Generally, it looks like most cylinders are firing pretty much the
same. There is one that looks either weaker or stronger, I
haven't researched it yet.<br>
<br>
For now, I need to figure out if I can adjust the timescale in
finer increments. I can either get about five pulses on screen or
10; I need to get just eight, and then figure out exactly which
one is cylinder number one, then I can examine each trace in turn.<br>
<br>
And there you have it, from the Pantera Research Institute,
Pacific Northwest Division, an inexpensive scope you can use on
the car. :)<br>
