They are not just eproms. They are an eprom on a board, they call them PEMs, Programmable Eprom Modules. And sent the bad ones back as requested, they are $100 each. There are two PEMs that replace the chips in the EZK and LH ECUs. The Shark Tuner is a separate box that provides a USB interface to the ECUs thru the cars diagnostic port. The Shark Tuner was $900 and includes 2 PEMs. The Shark Tuner only needs to be connected to datalog, do live tuning, or upload/download programming to the PEMs. AND I found since the ECU uses a narrow band O2, there is a separate connection to the SharkTuner for the wideband O2.

From what I understand I am supposed to use the Shark Tuner to data log, then move the data to another program called Shark Plotter that parses the data into a easier to read graphical chart. Then open a map file and adjust the fuel and ignition maps. Upload the edited maps to the ECU and repeat until happy with tune.

The average improvement is 10% over stock maps. That means a car with 350 crank hp can get another 35 by improving the fuel and ignition maps. There are 5 separate fuel maps used in various combinations by the ECU depending on throttle position, load, and if O2 sensor is actively being used.

Friend in Austin just called and i have tickets and a room reserved for F1 in Austin.

Thanks Glen. Just googled what it's about. Looks like what our ANZAC day will probably eventually become. Enjoy your long weekend everyone.

Wow, David, you have a more exciting friday night than me. I am laying in bed while my boys are jumping all around me. Trying to muster up the energy to give them a bath. Going to take them on a farm tomorrow to pick peaches.

That sounds like fun, tweeze.
