JB4 timing

Hello everyone,

New to this forum, but not new to cars. I am very new to the whole JB4 piggyback tuner. I have a 2019 G70 Sport AWD wih BMS intakes, and 1 step HKS plusgs gapped to .022. All of my other vehicles were ECU tuned. With that being said, I seem to be having some timing events with the JB4 tuner. From 3rd gear to 4th i have timing events in ign 2 through 6. They range from 1.5 which is normal all the way to 5.3. I'll attach a data log. I am running 91 octane because I live in Arizona and we have crap for fuel. I have really only used map 1 with the fuel situation.
