Summit 8701r1 gen 3 cam tune

Oh and what was it you changed in the file if you dont mind me asking?

If you use the compare feature you'll be able to see what's changed. But all I did was zero out the burst knock to see if that's what all the knock retard is/was. Didn't change so, that ain't it LOL

[InandOutPerfromance]

Ah i see now lol. Earlier you said i got some funky things goin on. Anything in particular that you dislike the most? Also in that link you sent, im assuming it will be used in the scanner correct?

[InandOutPerfromance]

Also thanks for showing me the compare feature. I literally was going pid for pid trying to see the difference. sheesh that is way easier lol

[InandOutPerfromance]

Well i eliminated brake booster. I blocked off vacuum hose to booster and repeated to only get same results. Cam was purchased under
the pretense that stall was not required, but is the biggest recommended. I wander if the converter is locking up and dragging down the motor.
Because it will not do this in reverse with same amount of brake applied.

What is it doing in D that it doesn't in R? Data log both and see if you can figure it out.

[InandOutPerfromance]

It may or may not look deceiving, and im sure you can probably see this. But in the logs ive posted where it goes red real bad
and is showing all the knock is at idle under breaking at stop signs/red lights. In forward drive. I can shift back to park and it
immediately rectifies itself.

Oh it's showing knock retard the whole damn time.

That's pretty much the exact behavior you get when there's something clanging around and triggering the knock sensors. You do know that the knock sensors can 'hear' things that your ears can't, right?

[InandOut]

Yeah, new to tuning not car's. Im going to go through the right up about iac counts and square that away. Ya know, one more thing eliminated. After that imma try and desensitize the knock sensors and play with fuel and timing in that area.
We'll see.

[blindsquirrel]

Just a warning - when you're new to this, like you said, be real careful not to fall into the trap of 'fixing' an issue with the tune that should really be fixed mechanically. Just because you can turn down the knock sensors doesn't mean that'll fix whatever is causing them to light up. That kind of thing can come back to bite you later.

[InandOut]

No doubt, i am very aware of this. I have looked over the truck very well. I your opinion outside of the torque converter being lock up. What in the world could cause so much labor knock at such a low rpm. Is my timing table way off?
Is the VE table screwy? The AFR's look out of whack?

[edcmat-l1]

The knock sensor system on the GEN3s sucked. Plain and simple. All that crap I can pretty much guarantee is all false knock. Pull a C5 Z06 file from the repository and copy over the knock sensor tables. Bet that crap goes away. I wouldn't hesitate to dumb them down at least that much.

[ilnvyb360]

Brand new to tuning and following along. I've installed the same cam in my 5.3 and could definitely use a solid starting point. Thanks for sharing! I'm hoping to learn more and more tuning tips everyday.

Ok i attached another quick log. The truck has been sitting all weekend and this is first start. Im logging the IAC stuff here and you can see when i put it drive IAC counts start to max.
Im assuming im going to need to tune the counts here and open up throttle blade huh?

Yes it looks like it needs more air. Also, it never went into closed loop, and one O2 is pegged lean and the other is showing rich. Need to get that figured out.

So to explain that the first and las files are speed density only, somehow i goofed and loaded a file where i was trying to get it better back with mass and o2's back in play. Sorry.
The reason for the o2 pegged is thats bung is being used for wideband. But when in speed density that shouldnt matter cuz stft and ltft are disabled. Again sorry.
Got the RussK logs downloaded. Here ya go

Speed density and closed loop have nothing to do with each other.

[InandOutPerfromance]

Speed density tuning... Meaning nothing is feeding the computer data to skew the ve table... Did you look at the log file?

Speed density only means you're running of the MAP sensor and VE table. Has nothing to do with feedback. You can run SD open loop or closed loop. LTFT on or off. These things are separate.
