Thanks for the abundance of info on this site its become a huge help in getting going with tuning my Challenger. I am trying to find a way to narrow down an issue I'm having and am not seeing it in the stuff i have been logging thus far. I have a 2014 RT with the Hamburger SC kit installed, their tune seems to be a mess which is why I am working through it myself. The tune they install seems for the most part to be ok but not quite there yet. My issue is when i down shift and get back into the throttle less than 50% more like %25 but to be save ill aim high. When that condition is reached lower RPM to start going and i get a jerk/lurch then things take off as expected. I am not seeing a huge drop in fuel pressure +/- 2-3 PSI on a remote gauge in cabin. My wideband is also not catching anything below 11.5AFR when this happens. I think that may be on the lean side but im unsure if that would be the cause or not.
Is there some specific things i should be logging in order to trace down the issue? I was reading about DFCO but im unsure how to log what could be happening with that as well.
Not sure, whats going on.
You can send me the file. What psi are you running, your Map is very low on idle and power.
Here is a file of mine.
Im running the Torqstorm. On this file with a 4" pulley and only 0,25 bar boost.
392 cam and injectors on a 5.7 with 2 Bar Map
I cant see the problem by watching the log file.
Try to get the long fuel trims a little closer.
I ve ordered a Mishimoto radiator to keep my engine temps under 90 C and use a 82 C thermostate.
I cant open your tune file.
