Need Help on the next Step

[Hoosierlong]

This is my first data log with TP. I have a 94 k1500 5.7 tbi 4l80e freeflowing exhaust ultimate tbi mods new plugs, wires, cap, rotor. Timing is set to 6btdc. Here is my first data log. Seems to run great till the rpms jump past 2300. Please let me know what I can do to make it run better.

Thanks Dave w! So would my next step be adjusting my timing curve? Very new to this but wanting to learn as much as I can.

[dave w]

Not every member has the same tuning strategy.

Data logs are a good way to "see" what is happening with the tune, aka rich / lean and spark knock.

Course tuning strategy:
Adjust distributor base timing to "see" what happens with the tune.
Adjust fuel pressure to "see" what happens with the tune.

Fine tuning strategy:
Adjust only a few cells in the fuel table to "see" what happened with the tune.
Adjust only a few cells in the spark table to "see" what happened with the tune.

Adjusting the distributor back to ZERO and adding 6 degrees to the entire spark table should have the same net effect on the tune. Typically adding 6 degrees to the entire spark table will increase performance. Sometimes adding 6 degrees to the entire spark table will cause spark knock and / or starting problems when the engine is hot.

Tuning is 3 dimensional.
RPM vs. MAP vs. Spark Advance
RPM vs. MAP vs. Fuel (Volumetric Efficiency / VE)

Typically an engine running at 5000 RPM's will need more Fuel than the same engine running 500 RPM's
Typically an engine running at 5000 RPM's will need a different spark advance than the same engine running at 500 RPM's

Typically an engine running in a vehicle weighing 7,000 pounds will have different fuel and spark advance requirements than the same engine running in a vehicle weighing 3,000 pounds.

Typically less spark advance will have less knock, but not always. Typically more spark advance will have more performance, but not always.

Tuning = Trial and Error

Step one - change something and "see" what happens:thumbsup:

Thanks Dave w! I will mess with my base timing first, try to find the sweet spot then go from there starting with 0. Great advice! How did I get to the first 2 tables you listed in your first comment? Another question, there where 3 bins ARAP APYP ANZA? Kinda confused on which one I need and what the difference between the 3 are? Also 2 XPFs, tpv4 and tpv5...I selected tpv5 when I did my data log and the ANZA one. Last question and I know im not there yet but the options under my truck, 94 k1500 5.7 only came with the 4l60 adx files through tunerpro website. I haven't had the time to check my ecm# but will soon. My truck came factory with 4l80e, all options except the 14b sf which I wish it did lol. The fuel pump I believe is stock, so 185k seems a lot and I have a new one from the earlier vortec after reading about changing it to that one as a suggestion. Something I plan to do soon. Hey I want to say thanks again for the help so far!

Definition Files $OE and $31 are the most common definition files for 93 - 95 4L80E vehicles.

I used an Excel spreadsheet for the top two screen shots in post #2. A similar spreadsheet for Wide Band O2 sensor (WBO2) tuning is posted here: http://www.gearhead-efi.com/Fuel-Injection/showthread.php?5381-Wide-Band-O2-(WBO2-Tuning)-Spreadsheet.

Thanks again Dave w for all the helpful information. Here is my up to date data log, fully warmed up with the base timing set to 0. Also I forgot to mention when I installed the new plugs, ac delco rapid fires, I gapped them all to 40. I will next pull all them and gap them to the spec of 35 then data log again. Please let me know if you see anything that has changed from your prospective. I also got rid of the high flow cat as it was rattling pretty bad. It was an amazon knock off and I regret buying it. Thanks again!

What .adx file did you use?

dave w

[Hoosierlong]

I used the 0D$

[Hoosierlong]

It was the 0D$ tpv5

[Hoosierlong]

I went ahead and downloaded the 0E$. Data does look different. I suppose that one might be the right one? Please let me know what you think. Again, thanks Dave w!

Please post the stock .bin file your started tuning with, I'll look to see what definition file your posted .bin file is. If you don't have the original stock .bin file, please post the .bin file that was in the computer when you used for the data logging.

First log was with ANZA.bin, 0D_TPV5_v250.xdf, and A217_0D_v250.adx. That was everything from the tuner pro website under my year and model. 94 K1500 5.7tbi. And it is all stock

[dave w]

I'm really challenged at the moment!!!! ANZA is NOT the correct chip code in your computer.

ALL the $OE and all $31 chip codes start with the LETTER "B".

We need to get on the same sheet of music if we are go any further.

Post pictures of the computer label. Post pictures of the chip.

[Hoosierlong]

Ok that I can do. That will be behind my glovebox? I will post back with pictures as so as I make time tomorrow. Thanks again Dave w!

[Hoosierlong]

Here are both the computer and chip. Thanks Dave w for being patient!

More confusion, but things are getting better. The computer is 16196395. The chip code (BCC) is BJLH.

So here's the deal ... in a sunrise in the east and sunset in the west way to thinking (it's just the way things are) ... $OD and $E6 are for the 4L60E transmission. $OE and $31 are for the 4L80E transmission.

The original post indicated a 4L80E, so that would be either $OE or $31.

The BCC BJLH is $OD for the 4L60E.

Please confirm the transmission is a 4L80E as indicated in the original 1st post of this tread. https://m.roadkillcustoms.com/wp-content/uploads/2018/09/4l80e-Transmission-Diagram.png

Take a picture of the RPO sticker in the glove box too. That will confirm drivetrain.

[Hoosierlong]

Just checked. Its a 4L60E. For some reason I had thought different. Sorry for the confusion AGAIN.

Ok, progress on the transmission identification:thumbsup:

To get on the same sheet go to the gearhead-efi $OD link http://www.gearhead-efi.com/Fuel-Injection/showthread.php?303-16197427-PCM-Information-0D and download the files listed below.

Advanced $0D TP5 v251.xdf
A217 $0D TP5 v250.adx

Download the BJLH .bin file in post #17

Load the .xdf, .adx, and .bin file into TunerPro RT and reply back (post) a data log using the files listed in this above.

I'll reply with a summary like I did in post #2. You'll need to "tune" from there on. The history table in TunerPro RT are adequate for tuning, but not filtered like the Excel summary I post.

Dave w, thanks for putting me on the right track. I have a LOT to learn. Here is a new data log with the right parameters this time. I hope to soon get it running as good as I can. Again thanks for your help!

[Hoosierlong]

I think I figured some things out. Due to a bad EGR Solenoid, it was causing lean fueling during cruising speeds causing high knock counts. Iv replaced so i'll see what happens next and keep data logging. I want to say thanks to you Dave w for helping me find all the right information out. With out you I would have still been data logging the wrong files. I have been reading a lot of the forums and they are very helpful! I don't have any equipment to burn new chips yet but still need to research a lot more before I get to that point. I think I get the big picture right now with Tunerpro rt. I have so much to learn and iv only put my foot in the door. Thanks again for the help, PlayingwithTBI had sent me your guys way.

RPO M30 confirmes 4L60e

Other good stuff GT4, G80 is 3.73 rear with Locker

[Hoosierlong]

I put 4.10s and a Detroit locker in it. Much better than that gov lock I think. I guess with the 35s it brings it back around the 3.73 range.
