Tuner Can't Tune Car

Totally agree but I was seeing weird things in the logs specifically with the exhaust cam phasers and wanted there help with seeing if it was something in the tune or a physical problem

Which adaptive learning? There are numerous.

I’m not sure Mike, I’m learning as I go.
If a tune is loaded is maximum performance immediate or is there a required drive cycle ?

From my experience the tunes give maximum performance as soon as they are loaded. Haven't noticed the Juggernaut tune getting faster over time and same for the Lund.

There is some transmission learning stuff but its mostly to learn how you like to drive the car when you cruise around not going wot. The fuel trims also learn but it shouldn't affect performance at all.

its immediate. Things like fuel flow (trims), throttle angle, airflow, cam timing, even some obscure things around injector and gdi pump control have kam learning. For virtually every control point there is a feed forward table, feedback control, and kam learning. The point of feedforward (much of the tuning like maf curve and phaser duty cycle) is to get it close initially and let PID feedback control fine tune it. Then it stores corrections so the feedback can work faster next time around.

So you are a troll, but ill continue to entertain you so others don't get confused.

The car runs good on the Lund tune. I don't like their customer service. I asked them to help me look at the logs to see if they could find anything and they talked down to me and when they sent me the "same tune" recompiled I could see it was a completely different tune. Thats why I am switching tuners.


Where did I turn down Wengerd? My car is my daily driver, I don't have forever to wait, and I understand he has no obligation to make a tune fast for me when he has other customers. And the cheaper option? Are you stupid? Wengerd costs like $350 for a tune. Juggernaut costs like $600 and I had to buy a new $400 device. If I just paid Wengerd for a tune it would have been like $350-$500 depending on how he has his pricing setup. Juggernaut was $1000.


I don't follow peoples recommendations who can't take the time to read and understand whats going on. Since you have posted its clear that your goal is to talk down to me an tell me I'm wrong without fully understanding whats going on. Go read a page or 2 above this and see how others have approached it completely differently than you

So just so we're clear here, you have a tune that works perfectly fine

So case closed

Yep

LUND only uses there canned tunes w/minor adjustments. You are not getting a custom tune. If you want a LUND custom tune, it's gonna cost yah more than a Las Vegas casino hooker during the high season - haha.

That Alex character stated multiple times there revisions are the same original tune with a different header for the canned stuff.

100% but most of their canned tunes run good. Case in point there base tune is better than Juggernauts and better than the tuner who couldn’t get the car to run properly after 19 revisions.

Lund was fine until I started asking questions about the tunes and asked them to help me trouble shoot. If you aren’t a big name you probably won’t get much time taken to look at things closely.

Even big name people and business get dumped on by Lund, Just ask Terry at Beefcake racing.

OP sent me some of his logs. I haven't had time to truly dissect them but Lund did use cam timing like Comp cams recommends for base tuning their cams. The other tuners tune had stock Ford cam timing.

That will account for the difference in 60 to 130 times.

I think Juggernaut is using base timing too and I think that’s why the 60-130 is slower. Haven’t done an actual comparison tho

You mean stock Ford timing?

 

[tdstuart]

Ya. I can send you the Juggernaut logs too. If I remember right it’s like 17 advance on exhaust and like 7 advance on intake. Could be wrong tho but definitely not what Lund is using

No, he has a tune that is fast but seems to be doing odd things or providing odd instrument readings, but the tuner wants inquisitive user to bugger off and not bother them.

"Working perfectly fine" is up for debate. If your only, naive metric is "fast yo", then yes it could be characterized as such.
