Boost held fine with 75% wgdc this time. Which makes me feel like it's not a hardware issue even though I didn't go fully to redline.
Here is a kickdown pull they asked me to do. Here I'm not achieving target boost, they had no issue with this when I sent to them.

Here is a 2-4th gear pull right after I switched to 4oz of boostane and the 91 stg 2. To me it almost looks like there isn't enough load or time in 2-3 to get peak boost then in 4th it's within .5-1 psi of target.

Here is the ACN map from a couple weeks ago where I was very easily maintaining target.

There just seems to be a lot of inconsistency between maps/pull/how the car reacts. This could be normal or not good. All I know is PTF says it's okay. Makes me want to get a custom tune and pay for the further communication from someone. Because as you said they probably get 100s of logs a day and don't always have the time to dig in fully.
I'll do a 1-4 pull and see what happens and report back. |
Looking at these logs compared to my MHD logs is pretty interesting. For example, in the BM3 logs they seem to modulate throttle position a lot more, but have a completely flat boost target. MHD is the opposite - requested throttle position jumps to 100% right away at WOT and stays there unless you have a throttle closure (e.g., for protection), and boost target fluctuates a bit throughout a pull (following target load). In the first log, while it looks like you reach boost target right away, throttle angle is still low. Your MAP is above target for a bit, but drops below slightly when throttle angle reaching ~100%. You are right though, WGDC is way lower than the 90s in your other logs. Not sure why the inconsistency there. Again not sure why the huge difference in load. The throttle closure down to 28% in the beginning of the log causes a huge pre throttle boost spike.
Looking at the 2nd log, the throttle angle is totally different and more what i see in my MHD logs - it immediately jumps to 100%, and your boost does not reach target. This makes me think you only reached target boost in the first log because of the throttle position regulation. This log also had higher WGDC again... and you can see the WGDC increasing, presumably trying to bring boost to target but unsuccessfully. This log looks more like what i am seeing in my MHD stage 1 logs.
Did you link the right log for the 3rd one? I only see 2nd and 3rd at WOT. It looks like you have a throttle shortly after the 2-3 shift and one throttle reopens you drop below target boost again. WGDC is kindof all over the place too, but with the throttle closure and other stuff going on its hard to get any insight.
The ACN log looks the "best" in terms of WGDC and boost; its even over boost by a bit despite throttle being open 100%. Looks like the target boost is 15psi in ACN and non ACN log. The load target is very similar in the 1st log and the ACN log 4th gear pulls. I assume they are just pulling some timing for ACN log. Was the only concern with ACN the overboost? I didnt look at timing too much but in terms of everything else this log looks the cleanest. How did the car feel driving with this one?
I am interest to see if your 1-4 looks like mine and is consistent with your other observation - i said the exact same thing about not enough load or time to reach targets in 1st, 2nd, and sometimes 3rd. In my 1-4 pulls i am way off (4-5psi) in 1st and 2nd, but get closer in 3rd, and can be within 1psi in top fo 4th.
Maybe we are both just obsessing because something doesn't "look" right in the logs, and this is all normal lol. Thats the double edged sword of having all this data at your fingertips.
FWIW MHD first said i have a boost leak, then i told them i reinstalled and was pretty confident i did not have one. They told me to reset adaptations, which i did and made basically no difference. I responded and they forwarded my log to another tuner and asked him to take a look, waiting for that reply now. I dont have a DP installed but could still do MHD stage 2 (just not 2+), which i thought about doing but the car drives completely fine with stage 1 right now so i am trying to stop obsessing over the logs and just enjoy the car for a while, with the intent to eventually get a DP and go from 1 to 2+
