Bad news, guys... Misfires are back.
I went for some Pbox testing today and I got limp mode on my second run. Lots of limp modes later. Same story - limp mode occures ~50% of all runs when I go over 6.2k rmp when doing WOTs.
WTF? Same cylinders even though I swapped the spark plugs and coils... I once even got misfire in cylinder 4.
What could be the reasons of misfiring?
Did a lot of logs, but don't know what to look for.
The car runs stronger than ever, it autotunes to 18 PSI on pump gas! I got some nice 100-200 kmh times. But those f*cking misfires... I start hating my car as I had so many problems with it...
