Are you using a pedal commander? Your pedal maxes out around 65% but throttle is fully open. And what ethanol mix are you running? I know it isn't completely accurate without a sensor, but in my experience it seems to get pretty close (from O2/lambda readings)...and yours is showing 66%. AFRs look good, fuel trims look good.

Your ign_1 (base timing advance) increases through the rev range with no pulls outside gear shifts which are expected. Your ign_2-6 (individual cylinder pulls, relative to base timing) are all 0s. Minor corrections (<3) are generally considered fine, so you're nowhere near octane limited and would likely be safe at a higher map.

No pedal command. Also I just started mixing E. I've been putting 4gal of E and the rest 91 till clicks which is almost 11gal. Think I should put 5gal and rest 91. Just doing a E30 mix rn and trying to make sure all logs are safe to move to an E50 tune.

Why do you want to increase ethanol? You already have plenty of octane/cooling, which is why you have zero timing adjustments, so it's just going to cost you mileage. If anything you should bump up a map on the same mix and reevaluate.

OK lmao. Just trying to learn how to understand the logs and to know what bad. I'm going to go map 4 and send a log. Is that a bad thing/or do you know why my pedal is capping at 65%?

Below is a post I made that walks through a log with real examples, and also contains the link to BMS's explanation. If you read that and do a Map 4 pull, you can compare the example in my post, and your Map 3 & 4 data, to get a feel for what things should look like.

I'm not sure why your pedal maxes out there, but your actual throttle is at 99% so it's not costing you performance. What drive mode are you in, Sport?

I’ve had my JB4 for a while now just installing it what a difference it makes I’m only a little concerned that I am not really able to read the logs do you know if I am running in a safe range love how fast it is but I really don’t want to hurt my car

I'm still an amateur at this, but here's BMS's guide, and how I'm learning to look at these:

JB4 Logging Parameters - JB4tech.com - International Turbo Tuning Discussion

Hey guys, We’ll use this thread for details and discussions on Kia specific JB4 logging parameters. Fuel trims and wideband o2 sensor control explained here...

I start by looking at Pedal, Gear, and MPH (light orange) to get my bearings...

Yup I'm in sport. Also I can't see your log thread.

Also I can't see your log thread.

Weird, thought I pasted it in. Try now?
