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-con...on-Diagram.png

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!

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

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

Ok, progress on the transmission identification

To get on the same sheet go to the gearhead-efi $OD link http://www.gearhead-efi.com/Fuel-Inj...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.

Here's the Glovebox RPO Sticker.

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.
