closed loop Lterm BLM's 120 help

[halfazn]

using datamaster to log my tune i found something wrong.

Lterm BLM's are comming in at 120, but the Sterm are balanced out at 128. I don't have exhaust leaks.

Please look at my datalog and help me to pick it apart. I have blended the table in vemaster, and am waiting to upload it to see if the patch has brought me closer to 128.

below are my VE tables: starting from 20kpa up to 65kpa in increments of 5

36.3 39.5 40.6 42.2 45.3 48.4 48.8 51.2 53.9 55.9
40.2 43.0 44.5 46.5 49.6 53.5 53.9 56.3 59.0 61.3
42.2 45.3 47.3 49.2 52.7 56.6 57.0 59.8 63.3 64.8
44.9 48.8 50.8 53.1 56.6 60.9 62.1 65.2 68.4 69.5
47.7 50.8 53.1 55.5 59.4 63.7 65.2 68.4 71.1 72.3
47.3 52.3 55.5 57.4 60.9 65.2 66.4 69.1 71.9 73.4
50.8 54.3 56.6 58.2 61.7 66.4 67.6 69.5 71.9 73.4
52.7 56.3 57.8 59.8 62.5 67.6 68.8 70.3 72.3 73.8
56.6 60.2 62.1 64.1 66.8 70.3 73.0 74.6 77.0 78.1

My question now is how do I get my BLM's to balance closer to 128 and not a lean 120? Thanks in advance

I am unable to upload the .uni file but can email if requested. New to forum and 1st day tuning and logging. Thanks

Welcome to tuning. We all beginners at one point. The .uni file can be attached, but needs to be attached as a zip file. We will need to know what definition file the .uni file is.

Tell me what size the DataMaster .uni logs are and I'll add some room and make them attachable.

120 isn't too bad, and it's actually indicating that your table is slightly too rich.

I have ziped both bin files and uni files, for reference. The only changes Commanded that will be different in the bin file is idle settings. I figured out how to change that last night. The uni file is from datamasterEE 4.0, and the bin file is from tuner cats.

Correct me if I am wrong but I read BLM < 128 was lean and BLM >128 was rich? I may be reading it wrong though.

My engine bolt ons are as follows.

95 Impala SS, CC502 218/224 112 lsa, 1.5 roller rockers, mid length headers 1 5/8 primaries, full 2.5" cat back true duals w/ H pipe, cai, 2200 lockup stall, 3.73 eaton posi rear gear, unmolested iron heads, MSD opti, MSD coil, LT4 knock module.

Thanks

uni is now a supported attachment.

My runs are making the files slightly larger than allowed. I am also unable to upload my bin files. The car is running better now though. Somewhere during full warm up and 10 minutes into the run the idle surges for a little bit. I am going to clean my MAF and just for the heck of it replace all of my Vacumme lines today if it stops raining.

What is the extension of bin file? I will raise file size for uni.
