a bit of a random question to most, but does anyone know what the maximum advance/retard is, that these gm-multec ecu's can adjust themselves to ?

AFAIK there is no adjustment per se. They run a RON plug to set max ignition and have no knock sensor. The only changes would be minor percentage adjustments for air/water temp.
With mapping you can change it free. I have definition file for tunerpro if you need.
Ohhhhh I'd like that
this is interesting,I thought you couldn't "map" their ecu's/AFM???
The multec you can, but no one really bothered
Which setup is that? Siemens or Bosch?
It's Siemens kit.
Been meaning to get hold of a corsa 16v to see how you could add boost to its ecu but alas they be rare again as mentioned elsewhere
