on EScope Pro
My ATS EScope Pro has saved me lots of time during road tests because I
can hook up to multiple CKT's at one time. One example was a 2001 Grand
Prix that a customer recently brought in. The customer complained the car
would not rev over 2800 rpm. It was almost like it was hitting a rev limiter.
The cell was on with misfire codes storied in the computer. With my EScope
I was able to look at multiple sensors at the same time. On a test drive
it didn't take long to get the car to act up. I was able to store the road
test and come back to the shop and revue the data. The EScope gives me the
ability to turn off different channels’ to sort out the data. After
enlarging the data I was able to see when the problem was occurring the
7X crank signal was failing.
The EScope’s eight channels helped solve the problem quickly with
as little driving around as possible. It also lets you drive and diagnose
the vehicle by your self so you’re not tying up two people. The Internet
tech support is a great help as well. The EScope has the ability to help
anyone learn to become a better tech.

on Pressure Transducers
To Bernie
and the people at ATS,
I've
been a shop owner for over 20 years. When one of your techs spends hours
checking a problem car then says "I think it's a converter"
it's not a very comforting feeling. The car was a 2003 Hyundai Santa-Fe,
2.4 liter with 73386 miles. The customer complaint was no power, car will
idle but would not rev above 1500. We checked the computer for codes,
fuel pressure, and intake restriction and they all checked ok. The feeling
was a possible blocked exhaust or clogged cat. unfortunately taking out
the o2 sensor or lowering the exhaust would take the rest of the morning.
We recently acquired the pressure transducer set from ATS which we use
to check timing belt alignment and decided to try checking back pressure
in a cylinder. After removing one spark plug and installing the pressure
transducer, we checked the wave form. it was clear there was little pressure
drop when the exhaust valve opened. So either the converter was clogged
or the exhaust valve was not opening, little chance of that. This whole
test took less than 15 minutes which was less time than taking out the
02. Making my job a lot easier. Thanks ATS.

Berkheimer on the Engine Performance Training Video:
The
students really liked the "engine performance material", and
the graphics and details were super! Great stuff for us instructors trying
to get certain concepts across! If "a picture is worth a thousand
words", then a 3-D graphic may be worth ten thousand!

Check
out this cool creation!
Just
wanted to drop ATS a line and a picture from the minimal regatta entry
we placed in Sundays race and won. This is an annual event held at the
schooner warf bar on the harbor. The rules are you must build a boat out
of 1 4 x 8 1/4 in sheet of plywood, 2 8 ft 2x4s, a pound of screws/fasteners
and a 60 yard roll of duct tape. Paint is optional and no sealers or caulking.
Our entry was the Speedy conch zales . Painted ATS yellow and Your logo
on the bow. Oh, we won fastest kayak design. Have a great day and keep
up the good work. Your system rocks.

I
have been using the Escope and I must say that it has been an excellent
enhancement to my arsenal of equipment. I already own two 4-trace scopes
and two 2-trace scopes, but there is nothing to compare when using an
8-trace scope where you can actually view 8 input traces such as injector
voltage waveform patterns, timing signals or computer powers and grounds
all at once. This is not just an 8-trace scope but rather doubles as two
8-trace scopes on a selected dual screen set-up that can be set to two
different time bases using the same input leads. This would be handy when
viewing fast signals (Crank, Cam, Coil primary, Injectors) and slow signals
(TPS, Map, O2) at the same time with both charts being synchronized together.
This dual scope screen feature also allows signals to overlay one another
and allows a user to better understand the associations the signals hold
with one another. The EScope includes a 6-channel signal generator that
has the ability to create dual O2 sensor outputs at any frequency and
amplitude, drive coil devices and output a variable 5 volt ref signal
in a linear or digital mode.

is a learning tool within itself and I consider it to be the
must have tool for the new millenium tech!"

Mc Laughlin on EScope:
ATS
is extremely convenient. For average and above average technicians it
is a huge time saver. Easy to hook up for intermittent drivability problems.
With 8 Channels you can usually get the problem in one test drive. With
thin 1/16” diameter wiring, you don’t have to worry about
crushing or cutting leads. You go for your test drive, hit the button
and save the data. You can re-set the system and get several data files
of the same problem just to be sure you’ve got it. But, you usually
get what you need on the first pass.
“You
can hook up and save data in a matter of seconds.”
It
is great to have the Injector and 02 toggle (sensor) on the same screen.
With the dual timing, analysis is quick. You can save the data and take
it home for analysis.
“You
can pulse injectors for as long as you like.”
“A
sharp technician won’t let go of this system.”
It
is worth mentioning again that it is convenient for test drives. You don’t
have to worry about the hood. It only takes a few seconds to save the
data. The 6 feet of cords is great and with the extensions you get 18
feet.
You
can take data home for analysis. You can plug the analysis into other
programs like AES Waveform Library and Paint.
“I
do testing the way I want to do it.”

Mc Laughlin on EIgnition:
For
me until now I had no confidence in “DIS” secondary ignition
scope patterns waveform’s displayed on a conventional ignition scope,
Capacitive [octopus style] pick-up probes that are out of calibration
and usually of a fragile nature [and expensive to replace] have to be
in good working order or the waveform displayed will not be an accurate
representation, or may be distorted, or may cause scope synchronization
problems if the tester is trying to invert negatively firing cylinders
unsuccessfully, when connecting capacitive probes you have to figure out
which cylinders are firing positive or negative and which probes are connected
to which cylinders, and if somebody previously replaced the spark plug
wires, positively firing cylinders may now be negative firing, and even
after figuring out all that the waveform display may be very unstable
and yield very little useful information, My way around this frustrating
problem [if it fells like an ignition misfire] was to install new spark
plug wires, test drive the vehicle, and if the misfire is gone, call the
customer and recommend new plugs and wires and hope that it gets approved
so that I don’t have to switch back the old one’s.
With
my EIgnition Tester there is no more guessing, the first thing that struck
me about the EIgnition is that it is connected directly to the secondary
circuit [no more capacitive probes]. No need to pay attention to firing
order and positive & negative firing cylinders during lead hookup, just
fire up the engine and make all adjustments directly in the EIgnition control
panel, were the negative firing cylinders can be inverted etc. Each cylinder
wave form has its own color code which makes cylinder identification a snap,
now I also have the ability to perform a cylinder balance test, kill any
cylinder I want to when I want to, trigger on any or all cylinders, trigger
on a injector or display an injector or 02 sensor wave at the same time,
I now have confidence in the “stable” waveform display and am
gaining a lot of experience in diagnosing not only secondary ignition problems,
but also those subtle misfire/drivability problems associated with injector,
low compression, valve seating and EGR problems.

It’s
rare when automotive diagnostic equipment delivers its promised value.
Our EScope, EIgnition Analyzer, Emission 5 Gas and tower are the exception.
They have eclipsed our expectations. Our imagination not the tooling is
our only diagnostic limitation. If we know what it is we want to see,
this machine will capture, display and save it quickly and easily.
Deep
record saves 10 seconds of 8 channel inputs at top resolution continually
updating in a loop. A single button allows for capture and the zoom functions
make for easy scrolling and examination. If you can make it to the scope
within 10 seconds of the intermittent you’ve captured it. Multiple
color graphs of max KV, burn timer, exhaust gases along with frequency
and dwell counters, TTL outputs and Mosfet pull downs makes this the command
station for combustion and engine management monitoring.
"If
your shop is engaged in electronic diagnosis on modern vehicles, there is
no more powerful or versatile tooling made. It’s not nice. It’s
mandatory. Once you have used this system you will never go back."

We
have had ours for about six months. We are still learning new ways to
use it. Last week we used it to monitor all seven relevant PCM inputs
and outputs on a Civic intermittent no spark. When the PCM igniter drive
failed we were able to verify that the PCM was bad because all the other
waveforms remained normal. With our old two channel scope we had to guess
which to look at first and Igniter drive would have not been in the first
test set. Today we used it with a First Look pressure sensor to verify
that a Toyota 3SFE did not have significant valve leakage after a bad
water pump caused a timing belt failure. The Labview based interface is
intuitive and easy to set up. Our “scope shy” techs have been
more willing to use it than other scopes we have had. Bernie has been
very helpful when we have had questions or problems. He designed this
to fill a desire he had for better tools, got world class engineering
to help to design it, and it shows when you use it. We have not found
anything to gripe about.

This
is a screen shot of a problem with a 2001 Toyota MR2 Spider electronic power
steering. The steering computer sets a code and shuts down the system if it
senses 100 Amps or more for more than .1 seconds. Try to catch that (and show
it to a customer) with anyone else's equipment!

Martin on Etrainer:
Thought
you would like to see a photo of our ETrainer being put to work. I have
started working on ETrainer worksheets collectively, giving individual students
the opportunity to lead the next "troubleshooting adventure."
I use a Modis scope and put the image up on the screen for all to see. Each
of the students have the reference information in front of them so they
can make suggestions on what to try next, etc.
