Dwell time with XS Engineering Ignition Box
 

I tried it and it was working fine until i mess with the car and forgot to download the program with a 40% less dwell/pump dwell (2.50/3.25). At 4.50/5.25 it burned 2 trailing coils and eventually the X4 igniter. Before that the idle, rpm smoothness, boost response and all that was better, I even had to decrease the fuel map % due to the better spark so i know the thing works.... but since the coil/igniter were so sensitive to the dwell times and there is no specific recommendations at the XS site for the MT ECU.... I would like to know if anyone has try it and with what pump dwell and dwell times?

mmm... so 1 guess i'm the 1st one ;)
