It looks good overall, but i noticed some things :

- your low pressure fuel sensor seems to be pinned at 55.7, that might indicate you need to replace this sensor
- your iat is too high at the end of your pull, you may need to invest in a upgraded intercooler
- your lambda afr 1 & 2 are a bit slow to reach 234 again, but if you gonna change your injector this week, that's perfect, you will see if it's slightly leaking injectors or lazy o2 sensor with a new log

You too

And the bov sound should come from the DCI, you can hear DV releasing pressure through the big filters and the increased boost of the V9 maps

Hi all,

E-mailed MHD for them to take a look at my logsÖ was on 93oct stage2+ tune, MHD replied and said fuel looked really good & for me to try the 95oct map, so I did. MHD said logs looked good for 95oct map while running 94oct fuel. Iím a bit concerned about this and wanted a second opinionÖ my concern is with cylinder 5 timing corrections as compared to the other cylinders. Iíve flashed back to stage 1/91oct as I recently installed a new clutch and was breaking it in. Now that itís fully broken in I will be flashing back to stage2+ ..
95oct log below

Way too many timing corrections on 95oct map. Personally would stick to 93oct map.

No worries mate,

If you want to run 95oct map even on a custom tune though, you need 95oct fuel otherwise you'll get timing corrections.

Custom tune on 93oct will be able to extract more power at the top end compared to OTS maps.

Yes, replace them :-)

The inconsistency is concerning, no suggestions.

2nd Attempt after misfiring on last attempt a few months ago. I finally got a chance to replace my plugs and coils.

Does this look safe for a daily driver? Can I set it and forget it? I noticed I have 3-4 degree timing corrections

Try Shell V power. If you've done your plugs and coils, you shouldn't have that many timing corrections, they are however minor mostly so it's nothing to be too worried about.

Alternatively you could run 91oct stage 1+ map.

Will the brand really make a difference? And I'm reading even on stock there are timing corrections :

Try it and see if it makes a difference, it probably won't but quality of fuel does affect timing corrections.

Which injectors are you running?

Can you log LTFT 1 and 2 as well?
