In short... er well bad choice of words...

but anyways there's a muscle in there that is too strong or very tense and its jepordizing the proper operation. /me not happy but thats another story.

Are you serious? Maybe you're missing my point which is any car that's pushed hard can have issues, but a flashed 335 puts more stress on the drivetrain than the stock configuration. If you're disputing this than I don't understand where you're coming from.

Thanks, Mike.

Thanks, Mike.

what im saying is you're pointing out the obvious. stress? how do you know that dinan didnt keep it within the limits of the car? you're claiming the dinan tune will push the car/parts over the limit.

This thread is just kinda retarded. Dinan should increase value since it's a tune with a warranty! you rather buy a 335 with procede? i'd say a 335 stock = 335 dinan.

Dinan or no Dinan, anyone who buys a used BMW without an additional warranty (especially the 335i) isn't bright enough to know the difference between a flashed car and a non-flashed car, how often the oil was changed, etc.

Sorry if I wasn't clear but I never said "the Dinan tune will push the car/parts over the limit." My point is that 300HP will not stress the drivetrain as much as (for example) 350HP. Of that there is no debate. The drivetrain may very well be able to handle the extra power but it will be more stressed than the stock car if the owner regularly thrashes his car.

Regarding the original premise, there's no way to know if the Dinan or other flash effects resale based on the OP's premise. I know I'd be wary of buying a used flashed 335. Someone who flashes their car most likely uses the extra HP regularly. I know I would.

Thanks, Mike.

around 1% of my driving will be hard driving = 1,000 miles per 100,000 miles.
Now others may be quite abit higher but for me those are the numbers.

Most of the damage on engines is from a multitude of things. poor maintenance, failure to warmup, initial start up, failure to blow out the engine ocassionally, incorrect fuel management, running hot, excessive beating on the engine/car, Revving,etc.

I use the example of using NOX on the people ask if their car can handle 50-75-100shot... and the answer is always the same yes but you must MUST make sure its even and used properly otherwise you'll blow your engine.

I agree that my analogy isn't perfect but still any car can endure a lot pain and suffering. When I get the Dinan tune I don't plan to track the car every day. Hell, I only drive my car on the weekends since I have a company car most often. So I might drive it rough once or twice a week. There are those maniacs that drive their cars like they stole it every morning but every used car has that possibility. I am looking at buying a used NSX and I get a compression test done on the engine to know for sure. There are tests like that and leak down tests that can measure how strong the engine is.

If the Dinan-flashed 335i can't be CPO'd, and I really don't see why it would be, then the resale value will be reduced.

Depends on the dealer probably. I know of Dinan cars that have been CPO'd.

Are these turbo cars, or just cars with Dinan pedals?

Not to belabor the point and no bashing intended but why would BMW offer an additional 50k mile warranty on a Dinan-flashed car when BMW's warranty must be supplemented by Dinan coverage for the first 50k? Does Dinan's warranty agreement with BMW include CPO cars?

I would think buying a Dinan car from an enthusiast is better than buying a "stock" car, because at least with the Dinan car the mods are transparent. You at least know what you're getting (in that you know what's been done to the car), whereas with piggybacks you have no idea what the previous owner did, whether it was installed correctly and the like.

Doesn't impact resale value from the seller's perspective. I guarantee you the dealer didn't pay more for the car because it was CPOable-they still pay as close to trade-in value as they can get. The only person that makes more in this case is the CPO'ing dealer. They pay roughly $1k to CPO a car and offer an extended warranty and mark it up from there for additional $$$. The buyer may or may not be getting a better value depending on how much they value a warranty and how much it is marked up.

The concept that a tune and/or other aftermarket parts reduces resale value is bunk. It may reduce the size of the available market and the perception and willingness of a buyer to buy, but the core value is still there because it is tied to other things, mainly condition and mileage. I don't yet see a line in the NADA guide book that says -$1,000 due to aftermarket parts. There are many instances of Dinan cars delivering more $$ back per tune $$$$ spent in return than other mods. Of course you paid 2x more for them too so in the end it is likely a wash.

Bottom line: DINAN tune does not reduce resale value.

Whaaa??? You can not CPO or obtain an extended warranty on a Dinan car, so why would anyone buy a used 3-series that only has ~ 1/3 warranty left?? A Dinan car will cater to a much smaller demographic, so the price WILL likely drop.

Are you 100% certain these cars came with the extended warranty and was the Dinan mod done to the drivetrain?

This assumes that a smaller market results in a lower price, but I think that premise is far from axiomatic. It might be true if you have a motivated seller who faces time pressures to unload the car, but for a patient seller who can wait for the right buyer the Dinan may command a premium. I think a lot of posters are conflating the smaller market vs. less valuable arguments.

[Sniz]

I personally would not buy a used 335 w/ 47k on the clock w/ a Dinan tune. I would MUCH rather purchase a similar 335 that is stock......most likely more life left in it. I'll mod it to my liking.

I often purchase used instead of new. In fact my 335 was purchased used w/ 1300k on the clock last April from a private party. No problems since it was purchased, cars in great shape. Now if that owner had engine mods I probably would have looked elsewhere in such an early production car.

Why did this thread get moved here from General to forced induction?

Mods: what's the point?

I would never buy a used 335i. However, if I had to purchase a used 335i, I would much rather buy a Dinan-flash car, then a piggy-backed car because a Dinan owner IMO will head straight to the dealer if a problem erupts due to the warranty provision.

Now if you could find a stock 335i (never touched by a piggy) then of course I would go for that, after a full inspection of the ECU/wires.

Sniz, I think you lucked-out with an early model 335i, before tuning/piggies became readily available.

or the welded rear diff

I agree, couldnt be happier w/ the car.

Well, if it would do a wheelie I'd be pretty pumped.............

[M4TW]

Since the Dinan flash is milder than stock when in the lower rev ranges and most of our daily driving is in these lower ranges, an argument can be made that the Dinan flash should extend an engine/turbos life since its saving boost for when it is needed.

The flash also has many other engine management enhancements (such as remapped water pump speeds) besides turbo boost that should add to the life of the engine.

Therefore, the Dinan tune should add to the resale value of the car rather than the opposite. I would use it as a selling feature.

In terms of buying, I'd be more concerned about improper maintenance than driving style. To me, a car that's been babied too much may have more problems with it than one that's been driven the way the car was designed to be driven - spirited romps now and then.

Anyway, my $.019961 Can.
