tuning ltft without wideband
Im new to tuning and trying to figure out how to adjust my ltft. Its currently over 25 in the red(Does that mean running lean?) It starts up and idles ok once warm. It also drives ok on the freeway. I posted the log and tune if anyone would like to chime in I would appreciate it.
Stock, modded?? What's the setup?
I see it has larger injectors for one. Is all the data correct for them and do you have proper fuel pressure around 58psi?
To answer the one question, +25 does mean it's lean. You will still want to buy a wideband for tuning.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
You are only logging data from Bank 1, the engine uses sensors in both banks for fueling. If the not-logged bank is running at -25 you don't have a too-lean problem, you have a crossed-O2-wiring problem.
