That is correct Peter, not enough amps.
Unfortunatly the LM1949 can't do better but maybe I can fool it with a voltage divider but I am not going to test that with my good injectors...
The LM1949 is a peak and hold driver, peak is 4 times the hold and currently the driver is delivering 4 times the amps that where needed to open the injector but when I look at some scope reading I found on the net of a running engine with those injectors I am still half way when I compare it to my scope. (but mine wasn't that expensive and is a bit hard to read
