Haltech injectors MS drop when throttle applied

I tried to look at the last datalog you referenced as showing 0% duty, but it won't load for some reason. Can you email it to me? chris@lms-efi.com
It's possible you have clogged injectors. However, that wouldn't explain what you're saying is going on with the injector pulse width.

The older logs I posted are still able to run in halwin. I'll email you that.
I spoke to a tech at haltech.
They told me that injector dc is just a calculation of engine load vs inj ms.
So it's not actually recorded in the data log from the engine.
Just sent the email.
Edit: on another note, since the injector dc is just a calculation, and the ecm is spitting it out as 0, and there are clear readings for my map sensor and injector ms, this leads me to believe that the computer is not calculating it correctly, and it may be faulty.
Ecm was sent out to haltech yesterday, so I'll be able to eliminate that variable...

For some reason it's not working for me now in halwin for some reason. You can still view it as a excel spreadsheet.

Not sure what they're talking about. Load has nothing to do with duty cycle. Duty is simply injection pulse width divided by available cycle time. Nothing more or less.
One thing I do see in the last log is that trigger before last home is a constant 2. Should be 11 at all times. Odd that you have that but seem to have a valid RPM reading.

What would cause the LTBH to be at 2 instead of 11?

also in this thread, this other guys was doing the same but no solution was ever found.
Did you mean 12 instead of 11?

Wow. **** me batman.
Had an epiphany.
I just realized that N and P move you down the rpm range on the 2d map. So I've only been tuning 0 rpms this whole time. The ******* e6x manual doesn't say anything about N or P in the 2d map section. But it does say in the 3d map section, you use arrows instead of N and P to move down the rpm range.

Turned up injectors on the text map. Still no go. Won't start. Pulled plugs, barely any fuel on the trailing plug and the leading plug is completely bone dry.

so im all wired up with my new Sprint RE.
Lean issue isnt a problem, yet.
I just got it to fire up. Idles relatively smooth, then after about 30 to 40 seconds it dies.
every time i start it its the same thing, 30 to 40 seconds of smooth idling, then dies.
AFRs in the 12.5 +/- .5
Checked my post start enrichment, which is 30 seconds long. it bumps up the fuel avg. 8%.
so i zeroed out the post start, and enriched my base map 8% across the board. no difference.
zero'd my ait sensor and coolant sensor settings, no difference.
locked my timing at -5 degrees, and unlocked. no difference.
heres a base map and a datalog.
again, data has been uploaded as xml file. just change to .csv
ive searched through everything and the only thing i can consider to be a culprit is a weak battery.
let me know what you think. thanks.
