OpenFlash DataLog

Hi,

I am running OpenFlash Stage 1.. I am having trouble with a misfire not showing codes and figured this would be a great time to log. I attached a picture of my log and I also attached the .csv if anyone wants to take a look and give their inputs. Any help is much appreciated!

I logged 3rd gear 2500rpm to redline and a little into 4th...

Thanks!

You have duplicate paramaters in lines 1 & 6, 2 & 3, 4 & 5. Alike items such as AFR bank 1 and bank 2, Trims bank 1 and bank 2, should be plotted on the same line. I don't see any misfire in that log. Looks like you went WOT at 4sec and have some sort of throttle closure at 5sec, but that's a guess since throttle does not appear anywhere in your plots.

Here is your datalog file plotted correctly.

Looks fine except for maybe you took your foot off the gas pedal at onset? or that was a throttle closure due to overboosting of target.

See if you can replicate it consistently

Thanks for the input guys, I know 100% I'm having injector related issues. I was leaking cylinder 6 and my bank 2 I believe is still acting up. I am idling at 700-800, that's not normal? I can also feel the car shake very uncontrollably under idle.

Sorry for the delay...
Definitely don't see anything misfire related in the logs. They look quite nice actually But if you have a stalling/leaking injector it's possible that it only stalls/leaks during idle conditions since that is when injector on-times are the shortest. This stuff unfortunately is best left for the dealer to troubleshoot and fix since it sounds like a hardware issue.

Yes, definitely at idle and leaky/stalling injector, only thing is I can't get her to throw a code

Glad to hear my logs look good, does this mean I'm gonna cry when my injectors are fixed?

lol... if the injector issue is isolated to idle conditions, it's probably not going to make the car drive any differently, under WOT, when it is fixed. So crying will probably not be involved
