This is what I'm login on my scanner.

I did compare them.

When I made adjustments to the PE I simply changed throttle percentages. Changes were made to the PE before I did the engine mods, if I remember right.

Quick question so I...

I have been looking at some other EGR WB calculations and some of them have an extra set of parentheses.

Mine is - 100*((2.3750*[2811.10])+7.3125-[50121])/[50121]

Othere on here are -...

Thanks for this. I know that we have chatted about the 50lb injector settings and I could have sworn I was using your suggestions, but I may have changed them for some reason. I will try your file...

This is the WB math that I'm using for my 30-0310 AEM sensor - 100*((2.3750*[2811.10])+7.3125-[50121])/[50121]. My manual says that AFR = (2.3750*volts)+7.3125.

2811.10 = EGR
50121 = Aif-Fuel...

I'll post the SD run from a couple days ago and the "test" from today later. But, it seems to run better today. It didn't go into KR as much.

Yeah, that's what has me going WTF. My SD tuning had under 5% correction. Should I just adjust it via stft and not rely on my WB? Or should I just put source it to a place like mailordertune? I've...

I would appreciate some guidance about this. I did multiple data logs and made many adjustments. After changes were made I put everything back to normal and did a test run. My SD map showed only 2-3%...

Thanks for the links! Should I add an actual PCV valve in place of the OE tube?

Any chance you would know of a "how-to" for this. I found an Evans Performance YouTube video, but it was just a teaser.

How would one turn the injector boundaries?

Yes, through the EGR. I have all of the EGR tables zeroed out to prevent any adder issues while its on. I included my scanner setup in the initial post, I think that will also show my WB on the...

Scanner file 5.17.22.1 is the first data log, tune file ending in "adj 1" is the post-scanner adjustment. Same for the second sd run. Each was about 30 miles. In the last tune, I took the KR graph...

Make sure that you zero out all EGR tables if you're going through the EGR on the ECU. I didn't and had a slew of issues.

Did you check your WB info packet for the math?

My daughter and I did some more MAF tuning after we had daddy-daughter dance practice. This time we did multiple passes with different loads. I took all of the values and exported them to an excel...

I made a "gut check run on the MAF. Here's what I did, I tried to simulate a dyno. I had my daughter in the passenger seat with the laptop. I would come to a stop, put it in 1st gear and accelerate....

I did the work on this motor last year and have about 2 tanks of gas on it. I replaced the following; freshly rebuild 5.3 heads, new cam, johnson lifters, new pushrods (measured for them), new...

After both were done I added 1.5 g/s to each table after the initial adjustments were made. I also included my setup for MAF tuning.

Here you will see the tune changes for idle tuning, the first run in park with scanner data.

NOTE: I realized that the MAF was still failed when I first started this tune. I had to shut down and...

Well, the time has come.. I go lost with so many different suggestions that I decided to start over. Feel free to follow along or give your two cents. I was following ChopperDoc, GRG, and others on...

I watched the HP Academy video on Idle tuning and there's a spot to put the max throttle body open percentage. This is to take the place of drilling holes in the throttle plate. Do the truck ECUs...

I'm currently installing 12613412 injectors on my lq4. All I need to do is copy and paste these values into their appropriate spot, correct? I understand that I will have to retune but I want to make...

Well, I came across some 12580681 injectors at a local junk yard and I think these will be a better fit for my combo. This article is what inspired me to build this motor, they also used 30lb...

No, you have lower compression than I do. Also, my MAF tune changed when I replaced it with an OE ACDelco one. My original MAF had a defective intake air temp sensor in it and about 175k miles on it.

Thanks, I made the mistake of following goat rope on YouTube.
