Agreed, and thank you for making the painful point that logs are a waste of time, when only 2% understand what they mean.Every one of your posts is simply "I'll let the logs speak for themselves" but you don't seem to understand that hundreds of people are reading your post with no idea what timing is or what it does. Without you explaining why these points are bad, you're basically gaslighting and coming off to be an idiot.
Running the turbos hard at high RPM can cause stress and unnecessary heat which isn't evident in any case since I doubt anyone has over 30k right now. I don't expect to see any numbers for EGT or any other relevant data point, but it's been noted in other car communities that holding boost up high is not good (with small turbos / outside efficiency range).
The same cannot be said about timing, the map will be specific to this car to most extents. If the ECU is not pulling timing back, why is it bad? JB4 is not intercepting / hiding the signal from the ECU.
On the other side, we have people running Lap3 saying that the 21psi they're running is no big deal (although they've been really quiet lately for some reason).
Oh yes they are hidding signal from the ECU, so... don't even get me started on load index and knock correcfion for hidden boost signal. Not only that, but the calculated cylinder pressures are going to be way off, like dangerously off to determine injector firing cycle (degrees in crank rotation that the injector fires at in relation to cylinder pressure).
To the experienced eye, you can look at a log and see how pissed off the ECU is in how jagged the logs are. A smooth log line indicates a happy ECU, a jagged pissed off line, means the ECU is making an attempt to correct, but the piggy back keeps adjusting to stop the ECU from successfully making the change.
Now, you want to talk about turbo heat and turbo life? The ECU calculates EGT's based on several factors, and boost being one of them is important, lol. Now we have massive amounts of boost, cranked up ignition timing, and lean AFR's that the ECU cannot see, lol. Because the piggy back is hidding all that from the ECU so... the exhaust temps skyrocket and the poor ECU doesn't even know its happening.
I could rant for days on how the ECU responds to changes hidden from it, but less than 1% would understand what I was typing.
