Kia Stinger JB4 maps

[d.lu]

Hello, I have a 2021 stinger gt2 with only intakes and exhaust. I was interested in picking up a jb4 and spark plugs. I would like to at least run map 2 which 93 octane is recommended for however 91 is is only available nearby where I am at. Is anyone currently running 91 on map 2 and have you experienced any problems with it? Thanks

Here in California, we can only get 91 octane. I have run map 2, but too many timing corrections. I even tried mixing in a couple gallons 100 race fuel (had to drive a long way to get it), and still wasn't too happy.
I have since played with mixing some E85 to get E30 (I have the Fuel-It flex fuel kit) running map 3, and this REALLY wakes up the car. Makes a huge difference. I only see very few small timing corrections now.

Where do you get the E85? We were just talking on another thread

On iPhone at least, there is an “E85 App”, it will tell you stations in your area.

Cool thanks bro

Fyi, even map1 gave excessive timing corrections for me (around 6 degrees). I definitely would not do map2 on 91. Mixed with e85 is another story, that works very well

Yeah. Best approach is to try it and get the logs and go from there.
