but i haven't tried syncing those tables, although what i linked in there did have both ATRA & ARA in sync, both flat. impressions are in there as well.

 

I got your logs. I will post them up in about a half hour.

 

They are posted in the new Log Thread:

Lemme know if you like that idea and you assessment of my stool sample logs.

 

It crashed with two logs opened and clicking around, but I liked what I was seeing up to that point?

 

Thanks.

I'm seeing the same thing with your file as i am mine.

I'm going to load one of my previous and see if it fixes it

 

What are you seeing!


The thing is so happy right now?

 

Ignorance is bliss.

I'm going to do some tech stream logging and double check. Nothing major, not even a problem really. In fact, i think we have been looking at the wrong info and it's slightly misleading.

Hopefully Matt will touch on it tomorrow as it's one of the questions i have asked before

 

You're killing me.

Ignorance is never bliss, esp after a tip of the hat.

 

This?

If so, I am not seeing that? I mostly see the TB holding a position, but no wavering open and closed. Thoughts?



It won't let me paste it any larger, but here's a zoom of the last pull (3rd gear, I believe?).

 

sorry i was at work and i cant do on my phone what i can do on my computer.

Figured id let you sweat it out for a bit.

I noticed that when i was logging the last two maps i had with the linear throttle i didnt have the ability to hit full throttle according to the logs.

I made other changes and thought maybe they were the culprit.

So i asked you to log yours, but i also was logging mine. I put my old map back in, but left the linear throttle.

I compared your logs to mine and it appears we are both maxing out at 60.

But i still question whether that is the correct PID for throttle angle, or if it is as VLADY says, duty cycle.

I know for sure the linear throttle map is way way way smoother. and yes your throttle is a smooth increase. But i dont think we are seeing throttle angles. I want to log further in TS to see what the PIDs say there. First i have to figure out the logging in TS.

I want the pedal to = throttle angle. i want full control of the plate.

 

No worries! Phones definitely suck, as does laptop screens at times.

I did not notice that. I will see what I can find later and with OBD.

That is why I added all of the throttle PIDs. The last set of logs that I made used just the default, which were the basis of the set that I used for this last group of logs.


Also, this current tune was just an edit on the last one.

 

Same as my before. Top is your pedal, full send.

bottom is your throttle, spike to full, drop to mid and slowly rise.

Now look at mine.

I dont have the throttle pedal logged, it doesnt spike here but it never goes full, it basically just does what the second half of yours does.



Im going to load the file i sent to @MOC221_ back in, that is the one that would hit full and stay there. THis is the picture. It is not as smooth, MOC can attest to that. but it does do this.

 

Unless of course VLADY is right. Maybe it is duty cycle. And its not the actual throttle angle. That would leave me chasing my arse.

 

Yikes! Nice sleuthing. I will compare with the other logs that I made on the previous edit. Definitely seeing the same upper value on Torque.

 

i also have a theory of the ECM learning taking over and putting a stop to it. I will know once i load the other file and retry the logs. The only difference in them is the linear throttle. however, i cant see that being the cause.

its not that i need full throttle, i mean, who really does, after a certain point, the air intake is not gaining much. at 2000 rpms, full throttle does nothing for you. But if you can make the throttle react in a predictable manner, you will gain predictable accel, predictable rev match, predictable decel.

i hate that im accelerating at the rate i want then the truck lurches forward even though my foot didnt change.

 

you guys are too cool

 

That file had REALLY snappy spots in it, I must agree lol.
I appreciate everything you've done and continue to do on these mods.. my truck drives smoothly right now and pulls well. But of course I'm still looking for that elusive throttle predictability.

 

This is the weird part. Torque is showing this and it is happening inconsistently. 1st, 2nd, and 3rd. AutoLSD and default. Sometimes it holds in the 80s and other times it is only there briefly.

The weird part is that my butt dyno is not feeling any change at all.

I think we need to ask OVT what the PID for the TB actually is. I'm going to look in vF. The Info dialog might?

 

Duty cycle is an "accurate" way of telling throttle if these throttle bodies are spring return. I don't know if they are or not.

Basically a spring puts pressure on it, the duty cycle of the dc servo will apply pressure and open only so much. As duty increases then it opens more.

That's where i got my numbers before.

In my little math example.

But I'd like to see tps readings.

And yes my linear file feels great but, one is too dead to take off

One doesn't have enough engine braking for my liking.

Both have a hole, where it feels like it doesn't want to do anything then boom takes off.

Then there is the other one where it feels great down low but really really takes off.

It's all really fun though

Taking a break from it tomorrow though.

It's fishing time with the wife. And my sketchy loading of a 12 and 13 foot kayak

 

I hear you!

OVT mentioned a return spring. That seems to be a good failsafe. If I remember, I will poke at it tomorrow.

Enjoy the fitchinn'. Kayak fishing is a ton of fun. My friend has a 12ft Compass. That thing is sooooo fucking fast. Just amazing.
