Engine has been started, we had to add the R30 pull-up resistor because it was not mounted (I assembled and built this system myself) but after that the trigger worked. MAP is steady, about 85 kPa @ 1500 rpm idle. As expected this engine needs lambda 0.85 (or at least below 0.90) to idle properly. This engine could _really_ use mappable fuel injection angle to get a reasonable idle and low load quality, or at least development should be pushed towards Alpha-N with pressure compensation.

The engine was only warmed up today and an oil pressure problem appeared that must be resolved before any more is learned.
