Sonata N Line Log Check -
03-10-2022, 01:43 PM
Hello all! I'm posting here for the first time! I'm not unfamiliar to tuning. The last car I tuned was a somewhat modded 2002 Pontiac Grand Prix GTP (supercharged). After owning a modern turbo for the first time, I see things are similar, yet very different!
Got my first couple of logs. I’m not sure what stock boost typically is on a 2021 Sonata N Line, but I was expecting to see boost to be fairly steady around 20psi on map 2. I don’t know how accurate the boost gauge is in the car, but it looks like stock boost is 15 psi, and the app gauge shows about 17 psi. Is this correct, or is there some tweaking needed?
I didn't bother to gap the plugs, however the car runs well! It stopped feeling as if it was surging, like it was starving for gas! Thanks!

Log Map 0 to find out what the stock boost levels are.
Unless something has changed Map 1 is +4 psi over stock.

I wanted to do that, but time, and traffic didn’t allow for that. I was more interested in the other maps! ��

Ok. After researching more, I’ll get a log of a 3-4 gear run from 2,500 rpm. Disregard the other logs.

So stock boost is about 13psi. Got a map2 log. Annnnnnd I’m gapping my plugs now. I had something interesting happen on my last run. Around 100 miles an hour, It went to shift, and it was like it got confused on what to do. It felt like it had half the power, started surging, and was maintaining 6500 RPM instead of shifting at 6,200 RPM. Seem like the clutches were slipping. It wasn’t the rev limiter.

If you get slippage on map2 then map1 is probably a better fit... That's more of a concern in cold weather.

In your csv file, or if you bring up the BMS software to look at your log, you will see ECU PSI. That is your stock boost. You will also see Target, that is what's added to ECU. Boost is the total combined.

Any thoughts on the most current log that I posted? I’ve seen AFR drop to the low tens. Is that an area that fuel can be taken out of, or should it be left alone?

None. I’ve been having issues with dataloging for couple of weeks now. It connects fine, and displays the info. When logging,it will stay connected between 5, and 15 seconds, then it closes the app, and doesn’t store logs. I started a new thread for that too, which I still have yet to receive any input.

I can only recommend three things to help. One, reinstall the app. Two, make sure the coms thing under the hood is touching no metal. Three, check the wires and pin connections again. Hopefully no frayed wires and such. Sounds like something in signal and communication and that’s kind of where my brain goes.

Already reinstalled the app. Didn't think about the com. Maybe something moved. Pins, and wires are good. I did recently install firmware version 21/24 T14. Maybe that's the culprit.

Is the clutch slippage a concern? Haven't heard this before.

No. I believe it may have been a learning thing. ECM calculates load, amongst other parameters to time clutch engage/disengage. I speculate that with the sudden addition of the extra power, it wasn't sure how to handle gearing vs. clutch engagement. It's not the actual clutches slipping, rather the ECM not controlling them properly. Only did it bad once. Then had only two minor weird events after. Been fine since.
