Car went into limp mode

[Jay.DeVries]

2017 Civic Hatchback Sport. 16k mi. Hondata tune. Did a pull, full throttle, almost to redline and the car lost all power, check engine light came on. Car wouldn’t move.
Showed codes
P0300 multiple random misfire
P0301 cyl 1 miss
P0302 cyl 2 miss
P0303 cyl 3 miss
P0304 cyl 4 miss
Pulled over, cycled the ignition. Was able to drive it the last mile home. Any ideas?

Custom tune or one of the base maps? If you take a data log (or have a recent one) I’d be happy to take a look.

how's your fuel trim? I'm going to guess you are running really rich and it misfired

I think i remember looking at your datalogs a while back ago and the fuel trim was really rich. you were over -10%

I just started having this issue, recently.
Everything is fine, until I try to run WOT after 4k rpm.

Had this same problem with my Sport Touring HB. Was my fuel trims with the Injen SRI +9 Basemap tune. Dc2turbo was nice enough to help and fix my fuel trims and it’s been golden ever since.

I feel like the Injen intake has really poor MAF housing QC. Seem like some users are running fine and some are running really rich

If you have an Injen intake, I recommend the stock intake calibration tha
n the Injen
