I got a JB4 tune for a 2022 Kia Stinger GT Line with a in line 4, 3.0T Liter. I got new HKS spark plugs with an injen intake and then the JB4 tune kit. I installed it about a week ago. I am running 93 Octane in the car and I have been running map 3 for about a week now. I have had no knocking of any sort and I just realized Map 3 needs 93 octane with a mixture of E30. In the app I thought it meant 93 to E30 can be used. Here is a graph with readings from a log in the app. Please let me know if these CSV's looks bad please and let me know if I can keep running 93 on map three or just stick to map 2 on 93.

I don't know enough about this to look at your logs but I wish someone would look at this for you. Map 3 is 93 or e30 though, not a mix of the two. E30 is already a mix of usually 93 and E85 to get to the E30 calculation. There are apps that will do the calculation for you of how much of each based on tank capacity to get you to that number. E85 in the tank first then add the 93 to mix.
Your 4 cylinder is either a 2.0 or a 2.5, I believe the 2.5 since it's a 2022. I'm not as familiar with logs for that engine, but in general it looks ok.
- Base timing advance (ign1) is in the 4-7 range, when I'm used to seeing ~12-16 degrees for the V6, but a log on page 2 of the thread below has the same thing
- AFRs seem high at times (~14.5) but apparently that has to do with either a handoff between port & direct injection around 45mph, or driven by EGTs (per Terry), after which it drops to 11-12
- Cylinder-level timing corrections (ign2-4) are all 0s, which would point to you having plenty of extra octane, but the JB4 thread indicates those values weren't available as of 2023. Maybe @AWDGT2 has more recent info.
Finally got our hands on a new 2.5L! - JB4tech.com - International Turbo Tuning Discussion
BETA 2.5t and 3.5t JB4 system available here: https://burgertuning.com/products/jb4-for-kia-hyundai-2 Was able to track down a local 2021 Genesis GV80 2.5L today for a little long overdue JB4 development and dyno testing! This engine uses the same connector system as the new 3.5L, both of which...

E30 mix for maps 3+ is about 5 gallons of E85 per tank of premium, or about 1.25gal E85 per quarter tank (so if you have half a tank of E30, you can add 2.5gal E85 and the rest premium to top up).
