Trying to tune my MAF curve!

[FreshDA9]

I was trying to overlay my logs over my MAF table {B5001} in the scanner. I made this MapB
14229
As you can see it never moved from 1500Hz; Also Hz wasnt slashed out when i was logging and I validated all my PIDs

Here is my PID:
14230

Here are some logs on the street:
14226 I did this log in 3rd gear (or attempted to lock 3rd gear)
14227 This was locked in 2nd but i had to shut down during the run
14228 This was me messing around no locking the trans in gear


With my truck should i lock my truck in 2nd or 3rd to make these pulls? I dont know about this gearing in this truck much but it is very wide from what i am used to. Just wanting opinions please.

You did not log MAFFREQ.

Damnit. I must not have had it selected on this PID list. Looking for GM.MAFFREQ correct?

[joecar]

Your wideband signal does not look right (at large throttle it pegs at 0.75λ).

Its the same serial LM2 i have been using. I am trying to figure out what it kept saying 12.3af and LTFT +14?

[joecar]

Use the LM Programmer software to see what stoich AFR is programmed into the LM-2.

yea i have never ran the LM Programmer software before. I will have to attempt this sometime this weekend. I am just hoping to get this running good and then move onto playing with the lean cruise to help with some mpg's!
