So I went back to v301, same thing but less. Stock map was fine.
Changed the 1 coil (cyl 1) and have been running v301 for the last 3 months again without issues.
The other day I thought I'll give v401 another try and the same thing! (cyl 6)
Can s.o. please elaborate why v401 is making my misfires appear...?
I'm at 54k, downpipes, dci, PE exhaust...
I had the same issue, my car and the OTS V4 ST maps don't agree with each other. V3 where ok and the Beta V4 where ok but once I re did the OTS V4 i had different issues on drive and sport map S1. Jerking like it wanted to misfire, strange gear shifts ect. Since changing to LT S1 sport no issues at all. run a pedal box as well when i need responsive throttle and i have clean pulls all the way to 7k where I used to get hesitations at 4k on each gear.
