Very likely excessively tuned for anything less than 94 octane. If you want to be on the safe side, you can mail it to me so I can read out the maps and compare to the stock ECU. Or, you can open 'er up and email me a pic of the ECU guts. Depending on how it's done, I can show you how to install a switch so you can choose the stock Z4 mapping or the Zero sports mapping when you use higher octane.

93 is still iffy. It if was tuned for 100RON, then you need 96. I would be interested to take a look at the maps and see how they compare. If you want to run the stock Z4 mapping until you get the details, you can pop the chip out and send it to me.
