Default n00b first log EVAR

Forgot AFR...doh! Anything else recommended to log?

3rd gear pull

Legacy GT UP/DP running 93 octane

Map is Accessport Stage 2 91 octane v1.15

I think everything looks decent... Knock correction is all positive, but should it be higher? Common for wastegate duty cycle to only be in 75% range?

It's okay - you don't have a wideband O2 sensor and taking AFR off the stock sensor is totally meaningless.

Not much you can really tell from that log other than your boost seems to be behaving very nicely. I'm not sure what target boost for an LGT with APstage2 is supposed to be, but it comes up and tapers off smoothly to redline which is good. No creep.

It is okay for the WGDC to be in the 75's. That is not something that will change a whole lot anyway - it's got a specific range it will be in based on the mapping so you won't see it go a lot up or down from where it is now. IAT isn't entirely useful to log here and turning it off would speed up your logging a bit or allow you to log something else useful such as dynamic advance (or "knock correction" or whatever your logger calls it).

Thanks for the comments.

I think I did log knock correction, third column from the right? Values all positive during boost, go to 0 off-throttle in the end.

Getting ProTuned on Monday, wanted to dive into logging and learn a bit about everything before I went.

Oh yeah my bad. You say you are running AP Stage2? I would expect to see those knock correction numbers at ~4-10 but instead you are seeing 2-5. Can you try logging the value called "Ignition Advance Multiplier" and see what it is? Just hook it up and grab it - it doesn't need a pull cause it is a single variable that goes up or down slowly over longer periods of time.

I am going to make an assumption here: I *think* the LGT's IgnitionAdvanceMultiplier should be a value between 0 and 1. You SHOULD be seeing it at the max value. If it's less than max, that means the car is pulling timing across the board and you probably ought to consider better fuel.

If the LGT's ECU is more like the WRX, the IAM will be between 0 and 16. and you want to look for the maximum value of 16.

If you have JUST performed a reset of your ECU, then it would be normal for the IAM to be in the middle of the range, as that is the default IAM after a reset. After driving a few short trips, it'll push up as high as it can towards the maximum.

LGT ECU IAM is between 0 to 1... Starts at 0.5 after a reset. I'll check it out tonight. Thanks again!
