Chipping my 335i at this point.. good idea?

Hi-

Figured the best place to get advice would be here, the community of experts and fanatics.

My 335i 2009 has about 75,000 miles. Just purchased it last month after a 2 year lease..

I'm thinking about chipping it..

Dinan guys at the BMW dealer said no, same with a couple other people. Basically saying the same thing, you don't chip an older car. Software is something you do in the early stage of it's life.

Are they right about this? Would adding some kick to my car at this stage make it a perfect breeding ground for issues and malfunctions? Or is it cool?

Thanks for the help.

What's up man I have a 2007 335i with about 90,000 and I have a stage 1 chip from Dinan. And It runs great you'll love it. Yea I know its has a lot of miles on it and ppl say don't do it but as long as you keep it well maintain, it should last you a while. I also have a cold air intake from Dinan and other parts on it. And I love that way it runs. It's gonna cost you a couple of thousand but if you got the money, **** it.

If the guy who would be selling you the product says it isn't a good idea, it's probably not a good idea.

My E46 was introduced to FI at 130k miles. Still going strong at 170k.

IMO the maintenance history of your vehicle outweighs the amount of miles your car has.

I'd be interested in what type of history the dealer could provide you assuming it was serviced there.

alx4n if there car is well maintained I wouldn't hesitate to load a performance tune on her, such as the Cobb Stage 1 tune.

If the car wasn't maintained very well in its previous ownership the weaknesses may surface after you tune it, regardless of what tune you decide to get

And yours is meaningful to the OP?

It's a fact that problems will surface with your car by tuning it if it's not up to "snuff". Sure you may not notice any problems running stock settings but add a tuner and I assure you will have issues down the road. You are demanding more out of the engine than what it was originally designed for.

This from a guy who probably never wrenches on his car and sells when the warranty is out....Do you even know how a tune works? I have seen so many posts like this....Tell me, when is the "right" time to tune your car? Is it just after the break-in period? Is it when you get to 15,000 miles so that the engine has had a chance to prove itself? You do realize that when an engine is chosen for racing purposes, it is preferred to use a "seasoned" block....Hmmmm, I wonder why...

For starters you don't know me or what background I come from. FYI, I perform all my own work and don't have warranty on my car. So......

I never once said it was the wrong time to tune it. I've seen N54's tuned from 5,000 miles and others are on 100k miles with no problems. Don't believe me then look on the other forums. I'm not saying don't tune it, I would. All I'm saying is that the N54 platform (or any other platform for that matter) was designed with a specific duty cycle in mind. Altering that duty cycle changes the life of the components. From what I've been seeing lately with all this E85 tuning, single turbo upgrades, it looks like BMW over engineered some things.

There is a huge difference between "seasoned" and "worn". He may not know how well the car was taken care of by the previous owner(s). It could have been owned by a 20 year old with mommy and daddy's money and beat the %&@$ out of. With more power there is always more risk associated.

I will admit that I don't know all there is about engines because that's not what my background is in. But this is general knowledge. The OP asked for opinions and I gave him one.

You got this...meaning that is one hell of an if. If the car was leased as stated, chances are it was maintained.

The "fact" is that problems will surface...it is only a matter of time my friend. No matter how well you take care of them. Since BMW over designs pretty much everything, this is probably one of the best cars to modify/tune.

You are correct, I don't know you, nor do you know me or the car in question for that matter. The guy is on here asking opinions about tuning his car which has 75,000 miles on it. You tell him that if it wasn't maintained properly it will begin to fail if you tune it. If it wasn't maintained properly it will fail if you don't tune it.

My point is that an engine is better off to be tuned after it has some mileage on it. I think we can agree on this. Since the car was leased I don't think the 20 something scenario has happened but that's the chance you take.

Just so we are all clear...I would tune this car. I see no problem with the mileage and would not think twice about it.

I think we are both trying to help the OP out just in different ways.

I apologize if I came off as rude...I would have called it snide or possibly sarcastic.

Hey Pal, I'm sorry...when did you become part of this conversation? Are you an internet bouncer here to straighten me out? Is this how you got your high post count? God knows you aren't an English major. Judging by your lack of punctuation, it is you that is the teenager. By the way, I corrected your mishaps. Next you will be threatening me....Get over it...you have nothing to say here...move on. Pfft.

OP I suggest seeking advice from an experienced tuner for example Cobb in TX. I'm sure they have tuned cars similar to yours and could provide general recommendations. I have a 335i with 45k on it and I just recently went with a stage 1 ecu flash from Cobb.

Good luck.

Your 335i is fine to chip. You can pick up a Split Second Turbo Tuner for under $250 on EBay, they take less than 20 min to install. I put mine on a dino after installing and got a 50 hp jump.

I put a BMS JB4 & DCI on a 335i E90 and the car is so much nicer to drive even when I am not pushing it... I can't imagine going back to stock. Had 65k on the car. If it blows up, I'll post it here. It's worth it. Like driving a brand new car I've never met. Shifts are noticeably smoother between 1st and 2nd... car feels like it was meant to be be this way.
