Lund tune/build thread (2nd attempt)

[Gibbo205]

Lund are hands down the best on communication and speed of tune updates, really they are in their own league.

How was fitment on those Hurricane headers and cost please [MENTION=15485]MustangDownUnder[/MENTION]?

Quote for install from the workshop (they manufacture the headers) was extremely reasonable, 2500 installed (on an auto..) this included ceramic coated headers/cats/hot dog mufflers, and custom work to make my FRPP catback join up with their headers to catback system!


V's all the other local options in Australia, the rest were significantly more expensive, and I couldnt justify the price difference.

After researching some peoples experience installing headers on a manual car and the fact that auto is more difficult, I was happy to have the shop install for me, they have the process down pretty well now, and for the install price.... it just wasnt worth the trouble learning the install myself for the first time and possibly damaging something on the difficult install side.

I could not get really good pictures of fitment, as they were working on the car and i didnt want to get in the way, ill add a couple pictures here which might help a little. ill take some better photos, next time its on a lift.

If you guys are impressed with Lund, another super star is Torrie from unleashed. I don't know when that bloke slept. I could email him anytime and basically have a new tune in 15 mins. This was with my Focus ST, he does mustang's too

I finally found an issue.
Ok, it's really NOT Lunds fault, but I thought I'd share it for the sake of full disclosure.
A couple of times now I've hit a bump whilst accelerating from a stand still. The result is a bunny-hop that looks like a learner is driving.

What's going on?
Well, a few things are at play here.
1. The suspension is STIFF. Bumps in the road translate into a jerky throttle pedal even at 60 km/h (can hear the throttle pitch change)
2. The tune has removed a HEAP of the factory stupidity in the DBW throttle settings
3. More power = more go. Anything you do with the loud pedal is going to be more extreme than a factory car.
4. Once that first lunge happens, my foot bounces on the pedal, makes it worse, and so on and so forth. The pedal only needs to move 1mm extra, and "it's on"

The cure:
1. Get Lund to dial back the DBW settings. :lol:
2. Avoid bumps
3. Stop trying to drive like a girl, just mash throttle at every opportunity (this is the most appealing option)
4. Leave car exactly as it is, push clutch in if hitting a bump, try again.

You covered my reply in option 3...why aren't you flat already!? That's not like you Burkey!

I found my own problem today... Previously I was using trap speed from the built in eighth mile timer. I can't do this anymore... I can't shift into second without blowing the tyres off through second gear! Don't get me wrong, this is NOT a bad problem to have .

My throttle response is also GREATLY improved.

We need more tyres Burkey..

For clarity, josh has had his car for 3.5 months (unknown kms) and has no tyres left. I'm not divulging anything at this point in time, but I will say that the Lund tune will improve share prices at Bob Jane.

Did you ever have the Lund tune loaded with the stock IM and TB?
If so, did you find the throttle overly sensitive or do I just need to HTFU?
A better way to explain this is that my "normal" mode is now more racier than the factory "race" setting. Or it feels that way at least.
I can see that this would be ok in either an auto or a car riding on factory suspension.
Very difficult to control in a stiff sprung, spherical bearinged manual with gob loads of power down low.
Even the "strip" engine mounts might be making it harder, cos there is zero loss of effort through the mounts. No "buffer" so to speak.

[Burkey]

You need to HTFU.

You need headers. And sphericals. And sway bars. And, and, and then?

I do not deny any of this.

Yes and yes Lund the throttle was never as good as stock in some ways!

Lund throttle mapping was better than stock for response in say normal mode, but I always found it made sport/race modes too touchy, though it seems our American friends do seem to like this, but hey pedal max, sprint booster type devices are very popular in the USA.

Yes normal on every Lund tune I have had felt more sensitive than race mode! :(

On AUTO cars this would indeed be find, the torque converter softens the abruptness of gear changes and stock suspension, it would probably be even preferred. In a manual though, its a bit of a no no.

When I had JDM tune, there tune was just a little more sensitive than stock, in fact it was perfect and the throttle was super precise and buttery smooth, but when I went to the PMAS CAI, JDM did not even want to try re-adjusting the car for it, the response was your tune looks good and we have never seen it so nothing we can. I am now on JDM tune for 350 setup to try, right now it drives aweful on their tune, but first revision, being waiting since the weekend for a tune revision. :(

Lund excel at customer service and extracting maximum power! But they seem not so great at throttle mapping.

I went over this with Lund several times, telling them, at first it was like our other customers have not complained, I got them to look, they made some tweaks, it improved, but I was like still feels pedal maxed, even on stock throttle body (350 setup). They then found some torque tables which were not stock, so they put those too stock, made an improvement for sure, but still felt too much. Then the guy writing my tune at Lund tried some of his own drive by wire tweaks, which helped but at the same time lost the initial response for pulling away.

My theory is someone at Lund, probably the big boss or master tuner wrote the base tunes and in these tunes I suspect he made loads of tweaks to the torque tables, throttle maps, drive by wire to make the car more responsive as it does seem 90% of customers like a crazy responsive throttle apart from me and you.

So when asking for all these tweaks to be removed the guys who do the tunes are not master tuners, they just know the more basic stuff like timing, fuelling and maybe some tweaks for the VCT/Cam angles etc. But when it comes to the throttle mapping, torque tables they either do not know how to do it or they cannot find the tables to make necessary adjustments.

The problem is, Jon II I cannot get hold off, I think he is the master tuner there because I would ask him to get one of his base tunes and to go through it with a fine tooth comb and reset all throttle, torque, drive by wire tables to the factory settings.

I think you want same as me, complete Ford factory on how the car drives, but with the extra power, unfortunately the tuners at Lund either cannot access those tables or do not know how.

My advice is you email your tuner and say look, my car feels pedal maxed, I don't want that, I want my car to feel and drive like the stock car, that means no torque table tweaks, no throttle mapping tweaks and no drive by wire tweaks, I just want stock! All I want from you is the power, please do not mess with the bloody throttle settings.

Please email them asking that, also put FAO: Jon II on your email then maybe he will see it, I shall also do the same.

If enough of us request it, I am sure Jon II will go through the base file which they must base most of their tunes from and correct the necessary tables in the tune to return all throttle pedal parameters to stock.

For me Lund is 99% there as they make best power and have the best customer service and response time.

JDM have the throttle sorted, but so far the car feels weaker and it surges even when warm, Lund did not surge.

SCT, just forget them, throttle was fine, but worse power of them all and they still left the torque limiters enabled

I shall email Lund again, stating the throttle issue is not just the 350 setup, but is your tunes in general. I want normal to feel normal, not like bloody race mode.

Just for some auto comparison, there is a bump in the road that often causes this same ...... issue? Near my house.

I have had to let off the accelerator completely and 'start again' or push harder to just get going smoothly, I have even had this happen once or twice on the stock tune.

But only when traveling at a steady speed (say 50 or 60 kmph)

Probably less so in normal mode, but I generally dont use that.

Any chance you can also email Lund asking them to set everything to do with throttle pedal to stock or at least tamed a little.

Only way we will get them to fix this guys is if enough of us email them about it.

Then the guys doing the simple tune tweaking will approach the master tune writer to sort the touchy throttle out.

 

[MustangDownUnder]

When I eventually get some datalogging done I could include something like that in an email.
I am convinced its more of a stiffer suspension setup that causes it though, as I have experienced this on the stock and Lund tune with both throttle sensitivities

I actually like the touchier throttle...... I could live with the stock sensitivity aswell though.

 

[stasik-a4]

I can say the same with mine auto when i hit the bump the foot slightly moves and makes the car behave that way with stock tune.
My other problem is out on the track on my 3rd session (approx 30 laps) the transmission starts to behave in a way that it does not want to upshift in sport manual mode using padles. There are no fault codes in the system or warning lights on dash, the dealer does not know what is wrong with it and the technical guys have nothing to go off.

It feels like the car is surging, starving of fuel or going into limp home mode, the dealer has update the PCM with the latest software the other week and i guess will see what happens on Saturday out on the track again.
I have my Ngauge installed and Lund tune ready to go, might have to flush that in at the track and see if it makes any difference and possibly data log it and send it away for review and adjustment.
Might even maybe get the technical guy out and show him the logged data and see what they have to say about that.They may have to fix it the same way that they have done with the Police mustangs and the simular issue that i think i might be having with mine.
