Most likely getting a 2013 335 IS. Was wondering if getting a Dinan Stage 2 tune is worth it taking into consideration no warranty issues with Dinan? Also they state if you get a stage 2 tune a intercooler is needed. Please voice any opinions. Appreciated. Thanks.

Dinan on a 335iS is pretty much pointless. The iS has the overboost function

Dinan Stage 2 gives 13.5 PSI to the foot at will, and dies off quickly at 5k RPMs

Stock Tune gives 13.5 PSI in over boost up to 6k RPMs for 7 seconds and then backs off

If you are thinking of Dinan Stage 3 it will only give you .5 PSI more over stage 2

If your worried about warranty but want to sleath it with the dealer, spend the money on the Dinan FMIC (My Opinion). If your leasing, then forget about it.

Look into something like Cobb as a tune which is more "convenient" to use. You can always revert back to stock tune before turning it into the dealer for whatever issues that may occure. For beginers, and warranty concerned, this would be the best move for you.

Why I dont have Cobb ? I am not concerned about warranty or the dealer giving me a hassle or flashing back to stock.

Also, the resell on the Cobb AP holds its value if you decide to go with another flash tune such as RENNtech.

Stage 2 requires an Intercooler and an oil cooler. Both of which your car already has. Only stage 3 requires an upgraded Intercooler.

Take it from someone who went the Dinan route at one time. IMO if you want to throw away your money to only do something else later, because that is what i did I am now Cobb stg 2+ and the tunes are night and day and you are able to flash as needed.

I never had warranty issues after the switch to Cobb i just flashed back to my stock ECU map.

I know they say you have no warranty issues but unless the dealer does it you will have issues. I had an independent shop do my Dinan flash and every time i went in with an issue BMW said it is the Dinan flash and said they needed to flash back to stock and see if it was the problem what a PITA.

Dinan worked but the gains are not that great going from Dinan to Cobb stg 2+ aggressive was scary to me at first then like anything else you get use to the power and want more I am now going meth.

Thanks to all for the information. Sounds like a huge waste of cash. I'll stay stock first to see how that goes before I do anything. Again a big thanks to all the input. Appreciated.

Get the COBB AP -- You'll be able to run their IS shelf maps. They're conservative, but it'll def give you a healthy power bump over the stock tune (even with the overboost feature).

AND you'll really like the simplicity of the COBB, you install right from the driver's seat so the hood never has to get opened. If you decide to mod beyond a tune (intake, DPs, FMIC, etc), you can just update to the appropriate Stage (Stg. 1+FMIC, Stg 2, Stg. 2+FMIC)

It really depends on what you expect out of your tune. If you want raw power, Dinan probably is not the way to go. But if you want to have some extra power without worrying about reliability, then Dinan probably would be your best bet.

I have Dinan stage 1 and a PE and am relatively glad with the power but I am considering stage 2.

If you like the way S1 comes on over the power band, you will love S2! For even more enhancement add the CAI and PE when you can and your done.

Want the extra power and reliability. Plus the dealer does the Dinan right there so any issues whould be handled with ease. In theory!

I bought my 335i coupe with the Dinan Stage II. I honestly dont know what a stock 335i feels like so i cant help you in that matter. I've been wanting to take the car to a dyno and see my numbers.

When it comes to warranty, you will have absolutly no problem with the dealer. Only bad thing is, if the dealer does a system update or some shit with ECU, it tends to erase the tune. They will have to re-flash it all over again. This was a dis-advantage to me because the nearest authorized Dinan dealer is 2 1/2 hours away from me.

I'd say just get the COBB. Everything is easily reversable. Good Luck.

"Launching on a flat highway, this 2007 335i screams to over 170 MPH (Speedometer ends at 160 MPH) - Standing Mile: 32.4 Seconds @ 164 MPH. The poor 0-60 MPH time can be attributed to low tire treads.
This car pushed 13.2 psi of boost through its 3.0 liter twin-turbo inline six cylinder engine, producing 421 ft-lbs of torque and 384 horsepower.
NOTE: How much the oil temperature gauge (beneath the tachometer) rises on this high speed run - The car was idling for a significant period of time prior to launch. The 170 MPH run was done with performance tires."

Stock except for the Dinan flash! So what's not to like?

I now have the Dinan Stage 2 and PE! Up until now I am happy with the power, but I am planning on the FMIC.

Since you stay in PR, a FMIC should be top priority which will come with extra power.

I know how the weather is there so enjoy and be safe. I will give you about a year then you will get hungry again

Ummm, the price? Sorry, but I think everyone already knows that... I personally question the dyno numbers you're showing, but as we all know anything is possible if you find the right dyno...

I'm sure your car is fast, I don't doubt that at all. After watching your video, I really wasn't impressed. It felt like it took forever to get from 100 to 160... You probably needed to shift manually to keep your car in it's peak power band rather than letting it run out to redline like you did. But thats just my opinion.

If you really want to find out how quick your car is, bring it out to Shift S3ctor in November. Hopefully we can get a good showing of 335's with different tunes...

Have fun and drive safe!

Agreed, Dinan recommends up shifting at 6100 rpm as it is just above peak horsepower.* After the up shift the RPMs drop into the range of peak torque.* This is the "sweet spot" as it keeps the engine constantly moving from peak torque to peak horsepower and back again.

FWIW, not my car or dynos! But I do have a Dinan stage 2 flash that I'm pretty happy with. Looking into Cobb, probably, after my warranty period and an FMCI in my future next spring.

[roadkillrob]

Search for the thread that someone just posted last week that has 2 335is cars, neither of which Dinan can get their flash to work on.

It's too bad there are not other options with warranties as Dinan get's a lot of business for a sub par outdated tune just because of the warranty.

If you compare apples to apples, there are a lot of better tune choices out there, but none have the warranty.

I only had to pay the 400 difference between stage 1 and 2 so I thought it would be worth it for a while. Next mod is the FMIC no doubt for the heat here in PR.

After that I am probably going Renntech. I am going to speak with the people in the local Mercedes dealer this week to inquire about them doing the flash.

I will keep you posted. I'm hungry already for more!

[Wedge1967]

Not sure why everyone thinks the dealerships are so concerned about mods. I running FBO with PROcede and leave all my mods on my car. Just put it in map 0 if I take my car in for service. I also had them note in my file not to flash my car. It would wipe out my PROcede Flash and I wouldn't be very happy about that... Good luck with your mods. Take a hard look at VRSF FMIC and DPs. Their 7" FMIC looks really nice. I'm running a HPF 7" FMIC and wish VRSF had one when I bought mine. Paid almost double what they are asking. But, I guess I got a good deal at the time and I shouldn't look back.
