2016 VT LT Fuel Trims high
Hey everyone,
I have been looking to get into tuning and i have been reading around the forum to see what other people are doing and looking through a few posts and logs I'm seeing most people have LTFTs real close to 0%. Mine are dancing between 10% and 14%. I would like to figure out if this is an issue before i go too much further. Also i would like to have a Stock+ tune figured out before i start modding it.
I was running 87, i have switched to 93 however i have not even run through a full tank yet. Maybe that's the issue?
I tried resetting the ECM by removing the battery negative cable but that does not seem to have changed the LTFT, when i started it back up it was at 14%.
The car is a fully stock 2016 Veloster Turbo Rally Edition with 71000 miles on it.
I am not noticing any adverse effects that might be related to this.
I am attaching the stock tune, my slight modifications to it and datalogs on stock (87 and 93 octane) and on stock+:

Is this an issue, will it cause any ongoing problems?
What should I look for to fix this?
Thank you,
Nicky
