I have Mototron/siemens 60lb injectors on a stock ls1 motor with turbo. My wot and cruise tune with them is pretty good except for a rich idle at about 12:1 afr.
I have my all my injector tables setup for these injectors. I can't seem to get my injector pulsewidth down below 1.8. I keep lowering my ve table for the idle cells for testing, its way low around 15-20 now. But the pulse width will not go any lower . I could start hacking the b3701 and b4005 tables but it seems like the pulse widths should be able go lower with these setting. How is pulse width calculated? Any suggestions?
Here is what my tables look like
b4006 small pulse threshold is at 3.997
b3701 Injector Pulse Width Voltage Adjustment
Battery Volts {link: GM.VOLTS}
12.0v 12.5v 13.0v 13.5v 14.0v 14.5v
0.68 0.607 0.53 0.47 0.41 0.34
b4001 injector flow rate table is at 9.2422 on all cells with vacuum/boost referenced regulator.
b4002 Injector voltage correction cells are all 1.0
b4003 and b4004 minimum pulse widths are set to .80 .
