Importing Injector Data

[rhighfil82]

Hey All, I'm fairly new to tuning. This is my first post, cause I haven't been able to find a thread on it.

Just rebuilt a 5.3.. It's now a 5.8, with new injectors. E38 ecu, 2009 Silverado.

I've been going back and forth between MAF and SD tuning, and I am getting inconsistent logs. Also, when I put everything together and run normal, the ecu pulls 18% on the LTFTs, even though that causes it to run lean according to my wideband. (LTFTs have been reset)

Anyway, I am guessing this may be due to incorrect injector data. All I did was bump my flow rate up, till it was in the range for 42lb injectors- for now.

I cannot figure out how to read this data sheet that DW gave me, and how to plug the numbers into HPTuners.

Could anyone help me understand this thing? Thanks!

Found better data I think..Hafta look at it later on the laptop.

That data plugged right in... still having issues with O2 sensors reading richer than the wideband, but that is probably best for another thread if I can't find the answer.
