Help me interpret my data log - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

carsebuco · 02-24-2018, 05:15 PM

I'm new to data logging, and I recently installed my CNT v2 UEL headers, and for no reason other than being paranoid I've decided to data log.

Problem is, I'm not sure how to read these. All I know is that the LTFT is a little low, and even then I'm not sure what the cause/fix is (or if there needs to be one) ...

What do you guys think?

Note: running E85

You'll get a good answer faster if you post there.

Unfortunately I don't know much about e85 tunes, but it looks like your fuel trims are very negative.

Thanks, didn't remember about that thread; never thought I'd be using it. To be honest, at first I just wanted to know if I had a exhaust leak, but seeing the LTFT it remined to ask about it again.
