Standard ecu maps on z22se engines .
The astra, vectra and zafira ecu maps are self learning by up to 20% from standard .
The rev limit on a vectra is 6750rpm .
This means the ecu will adjust up to 20% more when you have fitted performance parts .
After 20% you will need a re-map to gain the most out of your mods .
For example a 20% increase in air flow or fueling means the ecu can cope with it after that the ecu will more than likely overcompensate to a near standard map as original to the vauxhall settings when standard .
