OVC z22se tune up

Hi to all!

Searching many sites on the web about saabs and opels for tune up my OVC z22se (gmpt-e16), but nothing found.

Is there any ways now to tune up this ecu? I was read flash, but can't find maps in bin.

Someone can help find right way?
Do you have the Vectra C z22se? if so you will not find any new software upgrades as this cars ECU is only fitted to this car, no others so nobody has made any software for it due to it having a very small market.
Earlier Z22se cars, Vectra B, Astra G, Zafira A, and VX220 have a different ECU and these can be remapped if you have the right tools.
