c14se & c16se - gm-multec ecu's range of timing adjustment

[jimbob-mcgrew]

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???

[Stuart]

The multec you can, but no one really bothered

[Andy]

Which setup is that? Siemens or Bosch?

[phazer]

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
