No more guessing what cylinder is causing the problem
At times even the ECM can’t
detect the misfire so relying on scan tool data is not always the solution.
Thompson Auto Labs have developed a proven system that cures this headache. No
more guessing which cylinder is causing the problem.
To find a misfire, just follow these four steps:
- Start the ACE Misfire software on your computer.
- Select the manufacturer and engine type.
- Connect a lead from your Pico lab scope to an ignition reference for
number 1 cylinder, and connect another lead to the oxygen sensor of the bank
you want to test (or to the FirstLook Sensor in the exhaust).
- Click Start. It is that simple!
The ACE software uses the Pico lab scope to sample and display the engine
combustion data in real time. ACE displays a diagram of the engine being worked
on and flashes cylinders in firing order sequence. Healthy cylinders flash
green. Cylinders flashes red when a misfire is detected.
Once ACE has found the misfire you will be notified which cylinder is causing
the symptoms. By inputting key information into the software the ACE Misfire
Detective will also advise you of the most likely cause of the misfire — fuel
system, ignition system or mechanical problem.
How it works
ACE uses a Pico automotive oscilloscope to identify the high-pressure pulse
of the exhaust stroke of a misfiring cylinder driven by the unconsumed oxygen of
a misfire. ACE can also sense the high frequency dip in voltage of an oxygen
sensor signal when a cylinder partially misfires. By comparing the results to a
known database ACE is able to advise you as to what is the most likely cause of
the misfire. You can add your own vehicles to the database and updates can also
be downloaded from the internet.
You can connect ACE Misfire to a lambda (O2) sensor, however, to make ACE
even easier and faster to use, a FirstLook Sensor can be inserted in the exhaust
and a sync probe connected to an ignition wire (or an injector). Using ACE with
a FirstLook Sensor allows you to identify misfires by cylinder on any petrol
vehicle.
What you needed
ACE Misfire does not require any complicated equipment: a PicoScope
automotive oscilloscope and an inductive pick-up is all that is required. (A
FirstLook Diagnostic Sensor is also required if you want to test through the
exhaust.)
