This Wedensday I took possession of the PEM moduels from JDS (John Speake). These allow you to basically run what is like a flash style load onto the EZK and LH ECUs. That means you can reflash the tune at any given time without ever removing the ECU or chips out of them. The PEM stores the data and it is secure for something like 10 years. Each PEM has a battery inside the chipset.
The biggest advantage is being able to simply plug into the diagnostic socket of the car and have full access to LH and EZK in the SAME session. This means one can remap fuel and ignition together. Before this it was a "get it close enough" scenario where you iterated back and forth between fuel and ignition. My interior finally looks complete (it used to look like a messy electronics lab).
Tune on the fly, flash and go!
The 928's ECUs are now every bit as accessible as any modern system ever was. Proper engine management is the key to maximising (I dropped the "zed" in honor of Mr. Speake) power from your hardware and providing miximum longevity to the engine.
Nice pieces that are worth every penny. John and Niklas should win an award for creating these tools...they are
worth every penny spent. Hopefully they will come to one of the major North American shows sometime soon so we can meet them in person. I've been to John's place in Cambridge, England twice now...he's a really nice guy (an
incredibly intelligent person too). Working for a UK based company allows me the opportunity to swing by John's place every now and then. Though this year I'll likely only get to go to Germany (darn it
).
Don't tell Colleen...but I love PEM!!!
