GT 13.1 What's wrong?

[Livernois Motorsports]

That looks like the car is pulling timing or experiencing a misfire. Hence the bucking.

Beefcake, can you address this issue and get me a link a corrected file?

 

[Mark5825]

Is dataloging the only way to correct this issue? I refuse to datalog a car that is already unsafe to drive at normal speeds.

you said there were no issues with the tune originally but you didn't want to run it because

1) billy bob shop said it's not for your car

2) billy bob shop said it wasn't maximizing power

billy bob shop messes with car and tunes, and now your having an issue.

there is one common issue here

I'm thinking you loaded a canned tune, not our jlt intake tune.

TUNES DO NOT CHANGE

If it didn't do it before, it's not going to change now

You keep saying your tune doesn't change and couldn't change. Even if the shop did something reloading yours should have fixed that. You have not said one helpful thing to address the issue instead you have blamed everything else.That's fine if you're not going to help. Done with Lund and will never purchase a product from them or you. Thanks.

I have 0 issues with billy bob shop tune for the record. It actually drives me down the street.

It's a custom tune from a local shop (it was recommended by multiple people). Not going to say who as we are still working through things. I do have the Lund tune as it came with my JLT purchase. Messing around last weekend I loaded the Lund tune over their custom and it did feel better but there were 2 things I didn't like. Correction below----The first was the shop said the tune I was given was not very good and said I shouldn't drive on it at all---- and they had to write a completely different strategy (not sure what that means). I know a shop doing a custom tune is never going to say another tune is better but I'd rather the car be on their tune if something goes wrong for the time being. The other is when I tried to load the custom tune over the Lund tune I got a few error messages, figured out I had to load the stock one first and then the Lund but was still getting "you need to update device" errors even though it said updated. Finally got it switched but was a pain.

---- Correction they said it was not getting the most power out of it and that was the reason for saying not to run it----

what do you want help with?

you said you loaded the lund tune and had some issues getting it loaded. that's somewhat common on a 2015.

the cars have to pull additional files to get them updated for the car

However, no where in this did you say the car drove bad, or their was an issue driving with the tune.

That's why I am saying, I am more than happy to help, but it seems like you have a mechanical issue of some sort. If it drove fine before, but now it doesn't, the car has changed, not the tune.

If I'm not reading it right I apologize, but from what I'm reading there is something else going on.

I asked you to send some datalogs and you say you wont do that?

How am I supposed to help?

Here's a quick recap (turning into the long version, sorry):
Received Intake & Tune file
Installed by shop and Lund file loaded by shop
Car ran fine but shop said there was still power to get out of it
A couple days later (no issues at this point) went to shop for dyno tune which they got more power out according to their dyno
Car didn't feel as fast as I thought it should be even though their dyno showed power increases
Went back and they made a minor adjustment
Didn't feel any different so loaded Lund tune to see how it felt and that's when the issues started.
My car is violently bucking when I'm cruising down the road at 50 or so and occasionally on downshifts. I tried to put a little gas into it and immediately I feel a sound like metal grinding like the car is about to just fall apart.
Loaded custom tune from shop and car ran fine.
I deleted and re-installed the Lund tune file from my computer to devise and then to car
Drove around and it was better than before but anytime I let off the gas about 2-3 seconds later it give a kick (every single time). Not as violent as before but still not right.

I have loaded stock tune 1st and then custom tunes after
It has said successful load after every try
I only have 2 tunes available to choose from
I can not/will not data log on a car that can not even drive at slow speeds much less put very gas on it (I don't think that is unreasonable at all)

Questions that I have got mixed answers on:
Could the shop have accidentally changed setting on your tune?
If so, I still reloaded your original file, shouldn't that fix that issue if it was the cause?
Trying to just go back to the original tune you made and working from there. Maybe the original file is fine but I'm not doing something properly to load it.
I can load the shop's tune just fine after I load the Lund tune and I have 0 issues on the road so there isn't any issues with the car, the only time I have any problems is with the Lund tune.
At this point how or why any of this has happened is in the past, I'm really just trying to double check that Lund tune is exactly what is being loaded to the car when I do the load, if not then how do I make sure it loads exactly what you sent/made? If everything I'm doing is correct then there's an issue with the tune and I would like to know the options of fixing/changing it without having to datalog the car.

Just a little frustrating.

the key is that the car ran fine. that itself tells you the tune was a non issue.

so we need to backtrace on what they changed on the car. did you remove their tune and return the car to stock before reloading ours again?

that shouldn't matter, but it's still a good idea to do.

something mechanically is going on with the car. the fact that it's showing adjusted options itself means something was messed with prior to loading

without seeing datalogs, it's hard to say, but something is going on

 

[Mark5825]

Yes I removed their tune prior to installing yours.

So it looks like you referred to options changing but the tune not changing. I didn't see the distinction before. If that's the case how to I get the options back to what you had them at?

I don't understand the part about something being mechanically wrong with the car, it runs just fine with the shop tune.

where it's showing time adjusted in the handheld.

really , the best way for us to look at whats going on is via datalog, that's the only way to see what the car is doing and were happy to look at that

Have you tried starting from square one? i.e. remove the intake and try the factory tune and see how that goes.

If factory tune runs fine, then maybe get a tune from lund for a stock car (should be no charge for this).

If that tune runs fine, then reinstall intake and try Lund intake tune again. Maybe while you are at it ask lund to send you another copy of the intake tune - just to make sure.

Also make sure your handheld is completely up to date before installing any tunes.

 

[Mark5825]

I just want to load the original tune you sent that seemed to have no problems. Is that impossible now that the options/setting got changed? I understand that the datalog is how you get information but how is that possible if a car is barely able to drive?

I understand your logic but since I already have a shop that installed everything and did a tune and works just fine un-doing all that seems like a bit of a waste. If the Lund tune was all I was working with I believe that process would be worth it.

My device is updated, went through that whole back and forth process lol.

 

[Mark5825]

I really am trying to compare the tunes to see if I could get a better time with the Lund which is where this all started. If getting the Lund is this much work I can just work with the dyno tune I got and work with their shop. Just thought it would be a nice battle and was hoping Lund had better times actually, so I could go yell at the shop.
