That being said, I went over seas, did a tour in Iraq, and now that I am back home, I am going over things and one of them is installing a wideband and looking over my tune, because I want to learn more than I do, and taking one step at a time. So, the first thing I noticed was 110% injector when WOT. So I found the 12613412 injectors and asked for the data so I can change it in the tune. This is all that has been done to the tune and or the engine since it was ?street tuned? 3.5 years ago.
So, if my injector data is bad, I?ll need to source that, and looks like ?blindsquirrel? has provided his data, and if its uploadable to my tune ill input it. But, I like to research what I upload, as I don?t know him, or anyone, and I don?t want to melt a piston.
DFCO is disabled, I have no cats, nor vapor canister purge, MAF is failed verified by check engine light, dynamic blend high rpm is set to 12000.
The VE table is basically the same from 3.5 years ago and the 24# injectors. I have been removing fuel out of it, since it is rich, hence this entire post. Currently it is commanding .70 lambda (10.29 afr) at WOT, and that?s way to rich, I?d like to be in the .085 (12.50 afr) with my NA engine.
I?m sure you guys are correct if my injector data is off then the super rich afr is caused by it, and it was probably lea with the 24#ers doing all they could to feed my engine.
Last, 'fast4.7' stated "both the MAF and Dynamic airflow values should be very similar.." where are the dynamic values you are referring to? is that a gen iv VVE thing? Or I'm mistaking it as something else as i dont see it under engine-airflow-dynamic?
Thank you again for all your comments, it is very much appreciated and I take notes and use all the info for my own learning experiences and my own vehicle as the test bed.
