Would I benefit from a later shift to 3rd?

I havent looked yet but what fomo says is probably spot on....although 1450 isnt bad if you werent so rich then pressure would come up
You are depleting the rail of fuel...if you lighten the fuel demand then pressure should rise...and the only way to lighten the fuel demand is too tell the ecu there is less airflow...there really isnt less airflow but because you have an external fuel source the ecu doesnt know why the afr is so rich...thats why i dont like the current approach that some are taking to the meth tuning or lack thereof
Looks pretty good eleven....What do you think your fuel blend was? How much E overall? E20?
Knock sensor was happy....You had a little but I wouldn't worry at all. Don''t think it went over 2.
Your wastegate dutycycle seemed kinda high for only commanding 200kpa or about 15 psi. Could be the way torrie is setting wastegates, I dunno.
It looks like you had a spike in your stft's but when you look at the swing and how long it lasted it's really not bad....Looks bad on the graph but it was only 1.07 and it didn't last...It's because it was so consistent it makes 1.07 stand out
Your 02's were pulling a bit of fuel then at about the same time you got a boost spike at the 1-2 upshift that's when your stft's spike up to add fuel and that caused the slight fuel pressure drop...But at 1450 psi I wouldn't worry about that and it recovered quickly.
You are up on a spark limiter meaning you are running the max spark allowed so your knock sensor is not adding any more spark which is kind of unfortunate. But it probably wouldn't add much anyway because you got that slight knock retard so you were close to max spark anyway
Basically anytime the knock sensor is reading 0 for an extended time at wot you are riding a spark limiter. If you weren't you would see negative knock sensor readings....I would say the E is helping you. It looked pretty warm in your log but wish you logged IAT2. Because I suspect that was over 120-130 and you were still at about 19 degrees spark at almost 1.6 load so that's pretty aggressive spark
Car should be running well I'd bet

It was 85f+ outside when I did the log. I am glad that everything seems to be good but at the same time that pretty much means there is no more room for improvement which is sad because I would really like to get low 12s out of it the way it sits. With only pushing 15 psi do you think if torrie pushed more boost I would have a fuel problem with this mix? Yes it is about e18-e20. He did a revision for me today and the car shifts lil over 6k 2nd and 3rd gear which i feel helps and also the car does seem to pull a bit harder so maybe he made some boost adjustments. I will get a new log for you again since I need to send one to him also. Thanks for looking!AJP turbo said:

Yea low 12's is tough...That's what I'm shooting for....I mean you probably have room for a little more but when you want to keep creeping the boost up that increases fuel demands...And look at "fuel rear pressure" you can see the dips....Now add more boost which will increase load which is what really call for the fuel, then you want more E to the mix then when winter rolls around will you still have enough fuel? Maybe, maybe not.....Do you want to run your machine ragged all the time lol?
If I tuned your car I might give you another pound of boost and if you wanted more it would come with a warning and disclaimer lol

I look forward to hearing what a log on SHOnUups car would look like. I would love to know what mine looks like, too. Livernois sent me a revised tune that I thought would improve my track times but it was actually a tad slower than the normal tune that I had been running. I suspect it needed higher octane or maybe other supporting mods but that is only a guess. Would be nice to know the real reason.
This will be the last summer for my MKS so I will not be doing any more mods, anyway.
