Tunerview readings

[88_manzo]

I recently bought a tablet to see what my afr,ect and knock control are. I’m very new to understanding what they mean. Can someone help me out on what to have for my display screen readings?

Just my opinion from the research I have done and images I've paid attention to that other people have posted(as I had a similar question at first too), the things you want to pay attention to:

LTFT (long term fuel trims)
STFT (short time fuel trims)
Knock Control
IAT1 and/or 2 (intake temp before and after intercooler)
AFR
PSI (Turbo and MAP)

These items will tell your how well or not well your engine is operating.

But it also comes down to preference on what you want to show. I would imagine some people like to see their steering angle and throttle percentage while other dont. Personally, I want to see how my engine is operating especially with it tuned past stock.

Which STFT AND LTFT should I run b1 or b2?

Monitor the 1's. The 2's are only functional for V6 engines.

What are some normal Ltft and stft number to look for?

What are some “normal” ltft and stft to look for?

What are some “normal” ltft and stft to look for?

LTFT at + or -10 or lower. The closer to 0, the better.

STFT vary quite a bit. You may see a blip of say + or -15 here and there and that is normal. If you consistently see high numbers though (rich or lean) you may have a problem.
