Base Pulse Width. It's what the injector constant is labeled. That's how many lbs per hr your injector flows at full open. That's how the pcm knows how long to open the injector.
No need to re-invent the wheel. But we can make it better
So is it possible to have the scalar for injector flow rate set to one thing but then in the bpw parameters have crap still be turned up? I still havent fixed the min and max blm there must be some setting im missing.
Is it possible for some parameters to ovverride others?
Yes certain things can definitely override others.

I appreciate all the info thank you
Any luck finding that file?
I thought I PM'ed you a link to download the manual file. Do you want the open loop manual file also?
I have both files, let me know what you need.

Let me figure how to check my messages real quick lol
Please report back about how that bin runs after you run it.
I have the OL one on my laptop. Let me know when you are ready for it and I'll get it to you.

Yeah will do thank you I appreciate it.
So yeah the blm is adjusting properly now thank you. Also whenever the knocks occur the blm is like above 135 so that explains that i think. Idles way down at like 105
Just got my new wideband sensor in the mail today too so now thats working. I just got to connect the gauge to the pcm input and itll be in the data log. Afr at idle was like 11 too
So if you can confirm that the $od manual bin works with no known issues, I'll add it to my how to article. If you tie your 0-5 volt output on the egr position pin you can log AFR and run open loop. Another thing you can do with trimalyzer is filter for idle flag false tune main ve then change idle flag to true and tune idle ve.

yeah trimalyzer seems to work really easily and smoothly. ill see how it works in the tuning. trimalyzer can use the wide band data to tune in closed loop correct?
Attached is a copy of pretty much the only log file i have so far on the bin besides a short idleing log. I know its not good data i left DFCO on and PE and everything pretty much. i made sure egr was turned off and i loaded it up as is and test drove it and recorded some. so technically it isnt clean data and i was driving somewhat erratically i was checking out how it responded with various throttle input and i didnt have much time so it isnt quite a proper log but if you look at the blm averages its similar to what i was getting originally on the stock prom in the stock ecm which was $9A btw and anyways the bin seems solid it seems to be behaving as it did before i fucked with anything so thats good.

Great news.

I'm glad that bin preformed as it should. I created that modded bin to help another member on here, but I believe there was some sort of language barrier or something and I never had confirmation that it worked properly. I added manual files on my how to write up.
You can go ahead and download the manual zip from the article. The open loop bin is in that zip, along with an ADX that should log an afr error.
If you read the how to, you can see that I normally leave all that, AE PE Decel, on, and filter it out with trimalyzer.
