Gd1/gd3 Ecu

Hi there

I have been looking all over for some information on how the GD1/GD3 has their timing/ignition system set up. They use two sparkplugs pr. cylinder which fire with a very small delay thus "moving" the combustion thru the chamber and allowing faster flow.

Also, is the GD1/GD3 open/closed loop systems? If so, how many O2 sensors? Is there a sensor in the cat too? Does it use OBD?

Whats the flowrate of the injectors?

Any help, pictures, product codes/numbers would be apreciated!

Anyone?

Thanks Tony - at least we can agree that they use diffrent ECU systems for the GD1 and GD3 then. But I'd really like to know more about the ECU's - so keep em' coming!
