OFT Stage 1 Flash 3rd and 4th gear log

Re-did my log, starting at about 3krpm so it's better to read for any errors.

OFT stage 1 flash, BMS DCI, BMS cabin filter+cowl delete, AA chargepipe/bov
100% 93 pump gas from Shell

what do you guys think?

I think your data is being smoothed to show now timing drops or the OFT reduces the knock sensitivity or something else. No way you're running 10 deg adv and 16-17 psi through multiple gears without any drops. Your IATs indicate you have an FMIC but that's not listed in your sig.

Lol... There is no data smoothing with OFT datalogging. What you see is what you get. And what the OP is getting is a good tune that is well suited for his mods/conditions.

And Datazap is pretty damn cool. Good work Jpsimon

what does that exactly mean, like it senses some possible knock at that specific time?



Also to everyone else, it was 60 degrees or so that night, very cool night, the car LOVES these fall nights that are 55-65 degress, lowest it's dropped at one point was 49, way to slippery.

I haven't looked at nearly enough logs, but what is causing the quick dip in boost just before each peak? Is that from MAP sensor noise?
