I still have the orig K flash I believe (getting M flash early next week).

I decided to install the CZ unit this week. as I posted in another thread, It is not compatible with K flash at all- major low RPM problems- upper was not too great either. OK this is to be expected since it is tuned for L or M flash.

What I didn't expect was that turning the CZ off, the low RPM was still rather poor. It wasn't unitl I pulled the unit out that the car returned to normal.

I did not step on brake peddle after either the install or de install.

Also odd thing is that turning wheel R&L did not reset the DSC until the car was turned off then on.

Also the ECU and Stage 1 unit get really hot!!!!

 

The last part of the procedure from the Quick Tips says, "turn ignition OFF, then ON", so that shouldn't be too odd.
