Posted this on CompD and didn't really get any responses. I see it's been discussed in a few threads, but never had a thread dedicated to it here.
"For each main injection event this is the maximum degrees past TDC the injector will be allowed to remain open based on engine RPM."
So I changed it from these values:
Code:
Injection Shutoff vs RPM (Degrees)
0 42.007813
500 42.007813
1000 42.007813
1500 42.007813
3000 42.007813
3200 39.992188
4000 33.992188
To these values:
Code:
Injection Shutoff vs RPM (Degrees)
0 12.007813
500 12.007813
1000 12.007813
1500 12.007813
3000 15.007813
3200 15.007813
4000 15.007813
That was the only thing I changed in this tune. The truck would hardly start and when it did, it was coughing large amounts of raw fuel. This is something I wouldn't expect when I limited fuel injected after TDC. Has anyone else used this table? Does it do what it says it does? Any reason I'd go from a full-functioning tune (ran a 11.90 earlier that week with it) to nothing?
