Help...Lean pretty much everywhere!

Fuel trims vs. RPM/MAP

[1972C10_LS]

Should the Lambda Error chart be in percent for units or changed to number? Which also makes me wonder does the Lambda should be in Lambda units?

[1972C10_LS]

Something doesnt look quite right to me with the Lambda data during this quick startup,idle,rev log. I might just not understand it.....

Even though my gauge is set to display AFR the lambda data should still be correct right? Same 0-4.99v signal range coming from it to my ac sensor.

Ive attached my math params and scanner config files hoping this helps...

Thanks for all your help!

EDIT: FIXED AEM WB and LAMBDA MATH PARAMS....Makes a little more sense now....

Now what are your thoughts?

[1972C10_LS]

I think part of my problem was my original Lambda equation was mulitplying by .683 instead of adding .683 at the end......

I’ll have to look at it tomorrow, not on laptop right now

Heres my current config and a couple small logs.

I have a really long log session but it is nearly 10mb and it wont let me upload it. Can logs be split?

[schpenxel]

Should be able to export a section of it as HPL

[1972C10_LS]

Ok. I tried to split my latest log down so it would allow me to upload it in chunks. I think Ive got the Lambda and the AFR readings VERY close to matching the gauge display and what is displayed in the VCM Scanner. Ive attached the log files and the math params used. When I copy the Lambda Error data and paste multiply % into my VE tables it doesnt seem to remove much fuel? Must be doing something wrong...

Thanks!

What needs to be changed if the actual AFR and Lambda detected by the WB sensor is no where near the commanded PE ratio? PE is coming on like it should but is still way lean in boost. Theres points where it is commanding 11.25 and the AFR is almost 17? I have attached logs and configs. Any ideas how to get more fuel in those lean areas? I am thinking closed loop MAF or maybe open loop MAF tune a tthis point so i started logging the MAF frequency and airflow vs AFR, also logging Lambda..

Maf and or VE tables. I’ll try to check out log tomorrow.
