Pico Technology's Mixmaster PP361

Use with a 4 channel scope for best results.

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. A third channel is required to sync a cylinder for firing order reference.

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.

We do not recommend using the Mixmaster on distributor systems, the Mixmaster is most effective on waste spark 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 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.

Use a Snap On Scope?  Mixmaster works great with Snap On. The attenuation on the Mixmaster is 10,000:1.  This compares with the Snap-On secondary probes attenuation of 5000:1.  Snap On 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.

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
