93 octane on this log.

What’s the second column for on the chart?

For reference I’m seeing quite a bit higher lambse at WOT. No idea if thats ideal but sharing for reference purposes. Looks like at WOT I’m at .88-.95 at WOT . Below is a snap shot of one of my logs showing 100% throttle and the lambse highlighted. Later in the pull lambse holds steady around .88

I'm by no means a tuner but that sounds dangerously high. Lambda shouldn't change whether it's pump or e85 but if your at .95 at wot that's almost stoich. Maybe someone more knowledgeable can chime in but I always thought boosted cars usually target .78-.85???

I honestly have no idea if my log looks good but the tuner says everything looks healthy and I’m trying to go the “trust your tuner” route or I’ll likely drive myself insane second guessing every metric .

The column not highlighted between the two highlighted columns is MAFHz and the column reading all 0s (to the right of the 100s) is the torque source PID (0 indicates nothing is pulling power such as traction control or knock) at least that is how I understand it.

I just compared to another WOT log on the same tune and lambse is targeting .85-.93 throughout while at WOT.

.90 would be is dangerously lean. This is even lean for NA cars. You have to be seeing some crazy knock retard if you are running .90 lambda under boost. I would have to see the full log though as i cant see the lables for each pid

Knock is showing -5 KR. Is there any scenario where this isn’t dangerous? I haven’t asked for anything special in the tuning at all and I certainly don’t feel like blowing things up.

Knock is showing -5 KR.

Do you have the full .csv log

 

[LOL WUT]

Do you have the full .csv log

Does this allow you to see the full log?

You're actually running very rich. Short terms and target lambda are trying to pull fuel to lean it out. Look at the actual AFR numbers from the O2 sensors - AFR1 and AFR2

The plot thickens!

The plot thickens!

As does the air fuel ratio....
