Take a look at their description and opinions would be appreciated. I have not had my car tuned before, but am thinking about getting this. Seems fairly easy in install/uninstall if needed. https://products.vividracing.com/vr_...4387230577.php

 

OMG, it's been a long time since I've read so much gibberish and BS in one place. My favorite was "your satisfication is 100% guaranteed" along with "30-day, money-back guarantee," and on the order page for the Jaguar V6 product, it says, "product not returnable."

There are no data on performance gains, they just say it enhances performance. About the only way I could be persuaded to purchase something like this would be with a loaded gun pointed at my head.

 

lol..it is definitely vague. I wasn't sure is if vivid has a dent or poor reputation. What would best the most reputable ECU tuning: Eurocharged, Rica, other?

 

But they said "we KNOW these work" and were sure to use all capital letters. It must be true.

 

You know your 3-year warranty will be voided if you do an ECU tune right? That means paying for your service if you plan on keeping the car for that long. Just fyi.

 

Pehaps it's just an empty OBDII plug-in that doesn't reflash anything, and it works just like the placebo effect.

If that were the case, your warranty is secure as they claim it is "undetectable." That might actually be true in this case.

 

Not to open up this whole argument again but this is false. Magnuson-Moss Act etc. etc.

You can modify your car without fear of voiding the warranty. However, if a problem arrises that can be attributed to your mod, then and only then can the manufacturer deny warranty coverage.

I've ECU tuned many cars and never had a warranty issue.

 

You're right, you shouldn't have opened this up again. You are sadly mistaken.

Have you ever had major engine malfunction with a tune and tried to get it fixed/replaced under warranty? Magnussen-Moss only applies to things unrelated to the modification.

 

In what way? I'm not denying that manufactures will try to deny warranty coverage. They'll try that even if you never touched the car. Tuning a car doesn't automatically void the warranty no matter how many times you say it does.

Edit:
You added to your post. I haven't but I know people that have and had complete engines replaced, under warranty even though they had a stage 3 tune on them. The issue was a faulty piston valve.

Also your definition is the same as mine. The mod has to be the cause of the problem. If it is, then yes warranty denied.

 

I didn't come close to saying it automatically voided the warranty. However, if you tune an engine and you lose an engine, the odds are greatly against you on getting it covered, unless you have plenty of time and money to spend on lawyers and test engineers, while your car sits out-of-service for months.

It's hard to get around the manufacturer's argument that you altered the approved performance specs for the engine, which likely caused the failure. It's not impossible, but as I said the odds are heavily against you.

 

Oh yeah no doubt about that. It was going back to alexg's comment "You know your 3-year warranty will be voided if you do an ECU tune right?" That was the blanket statement that isn't true and I didn't want people to get the assumption that if you mess with your engine that you can't get your stereo fixed under warranty.

oh well, anyway back on topic. This product is probably bogus as others have said.

Did I forget anyone?

 

My reasoning for a tune would be to take my base V6 and allow it to attain the power/torque of the V6S which Jaguar decided to purposely limit in the base v6. I would think that doing a tune with what type of result would be fairly safe.

 

Yes...but where are those HP/torque increases found...way up in the RPM band where you'll really need to wind the car out in order to see any difference.

 

Very good point. Moreover, the difference in torque output between the V6 and V6S is essentially the same. As you said, the HP difference is only evident at the top of the rpm band.

The primary reason for the JLR-claimed .2 difference in 0-60 times is a difference in gearing. The base car is 3.15:1, and the V6S is 3.31:1. An engine tune isn't going to change that.

 

Correct. The only way to affect the midrange and related torque is with a an undersized SC pulley and/or oversized crank pulley along with a matching ECU tune. Whether the 3.0L can handle the resulting additional stress is a big question. On a per displacement basis, it is already outperforming the 5.0L. On a per cylinder basis, the 3.0L has some room for growth to equal the 5.0L.
