XDi/Motronic help

So I have built my 3.4 twinplug.
Xdi ignition starts and runs the car however.....
At cold start I have terrible hunting and at cruising speed 2.5k again the surging but not as bad. It is also running pig rich.
I'm putting it down to the Motronic DME not knowing what the ignition is doing and is trying its best guess to run the fuelling correctly..

Is there a way to make these two talk to each other as I am a bit dissapointed with the results so far.

Regards
David

Got your PM, and responded.

I don't have any experience with motronic and whether the fueling and ignition "talk" to each other. It really sounds as if your problem is fuel related...

Which XDI unit are you using? XDI2 = laptop programmable
