A few weeks ago the LS2 coils I've been running started to cut out. Long story short touching the harness made them come back. So I made another one from OEM parts and a weatherpack.
Now yesterday at AutoX the ignition cut out near the end of my 3rd run and the check engine light came on. The event happened at 6k rpm ish. I didn't have data logs running at the time and thought it might have been a knock event or something. I checked everything in the pits that I could. It felt like someone was flipping the on/off switch on my ignition. It still ran and idled when the rpm came down. It got me through the grid and all. I decided to try a 4th run and in the second turn at high rpm it cut out again so i coasted the course idling. This time I have a datalog. It was miserable hot out and intake temps hit 140s. I figured the coils got hot at first.
It runs and drive fine it seems as long as high rpm is avoided. When the cutout happens the AFRs seem to spike leading me to believe the ignition is cutting out not fuel injectors. I will add I swear the Walbro fuel pump is louder and nastier sounding at "key on" than it use to, but I may be hyper sensitive to things now.
The only things I've changed recently:
-new OEM to weather pack harness.
-started using launch control
-new brakes and RS3 tires (just on the list)
Here is the last run datalog.
On the drive home we replicated the cut out.
Not too sure about these setting. I swear I saw somewhere on the site it should be set to "going low" at spark output. I also think I saw that Spark Duration can go to 2ms.
Also am I wrong that all the "engine light" stuff is off? Not sure what happened.
