The Pico

12 Channel Secondary Ignition

Signal Mixer

 

 

Mixmaster can produce a parade display of up to 12 cylinders using a single channel of your lab scope. If you have a 2-channel scope, then Mixmaster can also display 2 engine banks separately with up to 6 cylinders per bank.

Mixmaster includes a trigger output, derived from one of the 12 input signals, which can be used to synchronise the scope to a known cylinder. Additionally, Mixmaster features a simple switch so you can invert a bank of signals to deal with negative-going signals on waste-spark systems.

Designed for use with the Automotive Oscilloscope Kit, Mixmaster can also be used on virtually any other lab scope, and can be used on both DIS and distributor ignition systems.

 

Mixmaster is battery powered and includes a low-battery indicator. The shockproof rubber case makes Mixmaster suitable for heavy-duty workshop use and incorporates a handy stand to make it easier to use.

Mixmaster is supplied with 3 BNC leads to connect to the oscilloscope, an engine-block ground lead, and a set of 4 short secondary ignition leads. Additional packs of secondary ignition leads can be purchased separately.

 

Mixmaster is a cost-effective way to display parade ignition waveforms on your lab scope. Compact and battery powered, it is ideal for mobile automotive diagnostics, and makes a valuable and inexpensive addition to your tool kit.

1997 Dodge Intrepid 3.5

Channel A: cyls 1,3,5

Channel B: cyls 2,4,6

Channel C: #1 sync

FO: 123456

 

The ‘Adario Method ’ shown above splits the positive and negative ignition firings between two channels enabling the observation of all waste and power firings simultaneously while a third channel can be used for sync.  

 

 

 

 

2001 Ford Windstar 3.8 IEDIS

Channel A: all cylinders power events

Channel C: #1 sync

FO: 142536

In the above Windstar example, we have multiplexed all the ignition power firings on one channel while using a second channel for #1 sync.  This is a multistrike system.

 

 

 

 

In this spit bank capture of the 2001 Windstar, we have zoomed in on the moment the system switches from multistrike to single strike

Use a Modis?  Mixmaster works great with Modis 7.2. The attenuation on the Mixmaster is 10,000:1.  This compares with the Snap-On secondary probes attenuation of 5000:1.  Modis has no way to set up a different range for scaling other secondary probes.  So, roughly double the given readings from a Mixmaster to get true KV.  Pretty simple.  Here is a little movie demo of Modis meeting Mixmaster.
