Tune With Cpo

[lokie17]

Hey Guys, I Just Bought A 2013 Mcb M5 That Is Cpo. If I Put A Tune Or Anything On It That Will Boost The Performance Will It Void The Cpo? Thanks

Well - technically, you don't necessary void warranty, however, if you have any issues that can be traced back to the ECU they can deny the warranty claim.

Example: If you have a bad turbo, if they see a tune they will void the claim typically automatically. However, per law, they are required to identify what caused the issue but knowing these dealers they are quick to point fingers.

If you have a bad exhaust system, its unrelated to the tune, they will accept the claim.

I personally am full bolt on, tuned, and modified. I haven't had any issues with the dealers. I have made a good relationship with the SA and techs so they take care of my issues.

JB4 if you are worried about your warranty. Personally, MCarsFan and I have been modded since day 1 and it's a night and day difference over piggy back. I've had the piggy and the car is noticeably faster over stock but doesn't compare to a tune IMO and from what I have seen, the piggy adds much more wear and tear on the car as its not running as efficient as a tune. With that being said, you have tunes out there that can f up you car if not done right so do your research. Great tuners on n the forums and plenty to read

+1 wise words.
Make sure you know what you want and ask lots of questions. Make sure you get a setup that's known to work. The guys that get their cars broken have shared their pain on this forum for all of us to learn from. ..

It's blast too.

I do not believe you can prove this statement "the piggy adds much more wear and tear on the car as its not running as efficient as a tune."

When you use a JB4 logs are taken and everything IS within order if you follow Terry's advice like not using Map 2 on a non-CP car without logging and testing. Without a JB4 eg just a bench tune - you can be running at risk and no way to know other than the tuners say - so- you have to have a dyno session to show AFR's etc are in order.

Best set up is JB4, BCM AND a flash. You can continue to get the mst from your car and monitor everything over time.

It's been proven over an over brotha. Running the JB4 (piggy) without a backend flash is inefficient, inefficiency creates premature wear and tear. Even BMS admits it's best paired with a backend flash to make the necessary adjustments needed for the car to run efficient. Piggy+backend flash is a great combo, we know that. We are talking piggy Vs tune.

Actually piggys are known to cause early replacement of coils and spark plugs. I don't need to prove this because so many of my mates who ran piggys before they were able to tune their cars had issues over time.

I also disagree that the best setup is a stack. Your point is valid that on a tune you have zero idea if something is going to break - but I feel that's down to the quality of the tuner you choose to engage with. I personally believe that there are only a handful of tuners you can go to because I believe they have data logged and made sure their tunes are solid. In my case, I believe the quality of the guy I have chosen to work with.

If you are looking at a high whp monster a stack is the way to go unquestionably but for a 700 whp set up, it's far less expensive just to load a tune.

I don't believe you can corrolate spark plug and coils on a JB4 - thats anecdotal. I am sure there are many who have suffered plug and coil failures on the OEM set-up and flashs.

What Terry/BMS has said about best set up is not to do with 'wear and tear' etc.

There are known protencial problems with all options including flashs so blanket statements on personal decisions and any corrolation on wear and tear need to be taken with a pinch of salt.

All good - different opinions are good. We provided the op with options and our opinions. I'm not engineer, nor claim to be. My opinions are based only on my personal experience and what I have learned from others.

OP - I'm not saying a piggy back is bad. I'm just saying that in my opinion, a flash tune would be better than a piggy. Having the JB4/BCM/Backend is great as well. I do not recommend the JB4+BCM without the backend. Each has its benefits. I'll just say I've have had the jB4 / BCM and I got rid of it twice and stayed with a tune only.
