Tuner Can't Tune Car

[shogun32]

The other tuners tune had stock Ford cam timing.

That strikes me as an egregious oversight. Do tuners not bother to consult the manuf release notes on their product?

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.

So you're telling me it doesn't work perfect fine? So my point is correct?

Don’t even bother. He doesn’t want to read the thread and already has his mind made up that whatever im doing is wrong.

He’s confused about the new motor vs old motor which the thread isn’t about, and he thinks that I’m wrong for looking at other tuners when my tune runs just fine. Even though I’ve mentioned that it’s not that the Lund tune doesn’t run good it’s that I’m noticing weird things in the log with my new motor and through the conversations I’ve had with Lund they seem either incompetent or just don’t care enough to pay attention to what is happening with the car, the logs, and the tune.

As I said way earlier. Are you sure the new tuners (both you’ve had NOT LUND) know exactly what cams are in the car?

If they’re using stock ford cam timing and you have Comp Cans in the car, either they don’t know it has comp cams or they don’t know what the baseline for theses cams should be. If it’s the latter, I’d make sure to send them the data and recommended base cam timing that came from comp Cams. Then try the same tune with only the cam timing change and see what that’s like. Then go from there.

Yep I specifically clarified with Juggernaut that they knew what cams I had and they said they were accounted for in the tune.

I don’t know what comp recommends for cam timing, will have to do some research.

And ya I’m going to have Juggernaut change the cam timing to match Lund’s and see what happens from there. Realistically not much else in the tune can account for such a big change.

Looked at Jug's tune and it is not stock cam timing but not what I expected to see either.

You really need a dyno and a live tune.
It went into cat protection but after your pull

They're trying to reinvent comps wheels.. COMP gives detailed cam timing specs. Follow them haha.

Jug is REAL conservative for ign timing. I think this is a base tune to make sure everything is solid.

Tristan let him make a revision or 2 before you give up.

That’s revision 4 haha, but I’ll keep working with him for a bit. They told me it’s not a low power tune

It has less timing than factory stock. He may have sent you a miss labeled file.
Knock is 0

 

[WildHorse]

t has less timing than factory stock

Yikes haha. I'd just give it timing until the knock sensors are unhappy. Then back down a degree or two.

Just to clarify you asked Lund about your logs and they told you it all looked good and no issues with them right? But you in your tuning expertise belive they are wrong?

They also told me that two clearly different tunes were the same tune. So yes in my extensive tuning experience opening up a log file and using my eyes I could see the exhaust phasers were behaving differently on the same tune from new motor vs old motor.

And how do I know that two tunes they told me were the same were different? One, the new tune was over a second slower 60-130, and two you can view the datalogs and see the commanded vct is completely different.

So yes i don't trusts Lunds ability to analyze my log files when they can't even tell they are sending me two completely different tunes.

pardon the ignorance...

Unless tuning for a specific fuel characteristic (eg. E85) why wouldn't the timing be broadly the same (upper and lower limits) for every Gen3 NA v8 Mustang? For example let's say Mr. Tuner-I-blowup-customer-engines-because-marketing-WIN sets "allowed advance" at 40 degree as the upper bound, doesn't the control logic have the means of chopping it off at say 32 if the knock sensors assert themselves? Why would/should the tuner reset the upper-bound value to 32 minus a couple?

I thought there was slow-ramp logic in things like spark advance.

The first paragraph of the first post

"Decided to switch from Lund to a new tuner as I didn't like the customer service I was getting. Lund tunes were good but after the motor rebuild something was wrong and Lund kept saying the logs were fine (although I could see some phaser differences) and each new tune they sent me made the car slower even when they said they were sending the same tune (clearly could see cam timing was different in the logs)."

Your entire complaint was the car so slow, not whatever shit your babbling about now
