You don't see many BMW 335I TUNING GUIDES/FORUMS That are organized really. Here's a tuning guide that I was thinking about over the long run. I recently bought a E93 Space Grey 2009 bmw 335i, and I was thinking about modding it already.[/

Theres many ways to make a 335i a "V8 KILLER" but realistically speaking, are you ready to put the blood, sweat, tears, and the money into your beast? is it worth it? Can you get power out of it? OFCOURSE YOU CAN.

Its all dependent on what you're trying to do with your 335, if you're going to make a track car, go for it no ones stopping you!
The things I am listing will be about having a "STREET FRIENDLY" 335i regardless the Loud noises, popping on downshifts, and the crazy amounts of speed.

MODS TO DO:

-JB4 G5 ISO
Of course you're going to have to do the JB4, but with the JB4 comes maintenance.
-Catless DP CERAMIC COATED

1. Sounds awesome
2. MUST BE CERAMIC COATED, IT WILL HEAT UP.
3. Helps your turbos breathe better

-AFE DCI
THIS IS A MUST FOR SOUND,COSMETICS, AND SOME POWER.
SOUNDS BEAUTIFUL, YOU REALLY HEAR SOME BAD ASS NOISES COME FROM YOUR CAR.
-NGK HIGH PERFORMANCE LASER IRIDIUM SPARK PLUGS
with the jb4 comes many different costs, you never know, one moment you're on map 1 chilling and driving, next red light you're right next to a Mercedes E55 AMG and you switch it into map 5 and take a dump on it.
But while you're doing that, boom, misfire. JB4 doesn't damage parts, it just provokes you into doing so, you speed more, you abuse your car more, and boom a parts out!
-WAGNER INTERCOOLER
If you're going really fast, you're going to really need a Inter cooler with all these mods. Stock Intercoolers do a great job at cooling the car, but the car seems to "Lose Power" after being very hot. Wagner was nice enough to supply me with a discount code, and a sick lanyard at bimmerfest this year.<3 Much love, Wagner


You have to be spot on at changing your NGK Spark Plugs every 10-15k miles.
IT IS A MUST
I would change it every 6 months just to be safe, even though its unnecessary.
You might have a coil burn out but thats no problem, just replace it.

ALSO OIL CHANGES ARE VERY IMPORTANT, I USE COMPETITION OIL, THATS JUST ME THO, AND I CHANGE EVERY 3 months.

The biggest thing that leaves people "IFFY" about tuning a car is warranty.
These are mods you can do in your backyard with a jack, but I wouldn't push it.

These mods are all mods that are very easy to put on, and take off for your car to go back to stock.

Of course, the JB4 is Illegal in California, use it at your own risk!
People who mod, usually fear their warranty getting voided, I have 100k mile warranty, bone stock 335i, but soon to be modded with all of the above.
Currently at 60k Miles, and its a 2009 e93. Heavier than other 335i's but man does it fly.

With all of these mod's done correctly, you should be doing 380~440 RWHP
IMO on map 1, if I even do 390~400 whp, I would be the happiest camper alive.

THIS IS 91 GAS FRIENDLY, IF YOU'RE TRYING TO FLY, GO AHEAD NO ONES STOPPING YOU TO MOD IT FOR E85/METHANOL INJECTIONS

DRIVE SAFE EVERYONE!

TECHNICALLY SPEAKING, I'm trying to make it a guide for people who are still bone stock, something like "What to do and how to maintain" sort of thing.

[335e92tx]

Then consider making a recommendation that (depending on mileage) these maintenance items also be performed

Coils (50-60K)
Waterpump - Thermo (5 yrs and 60-80k)
OFH gasket - VC gasket and Oil Pan gasket leaks (5yrs and 80K>)
PCV - 60K>
Turbos - 80K>
Coolant recovery tank - Top rad hose - ?? anytime after 7 yrs really.

And there is a similar thread

Nice start! Many have differentDifferent approaches thought. My recommendations to a bone stock car are quite different:

-start with mhd tune - there is no reason at this point to purchase any other tune. It's cheap, simple, and a flash solution that works, and can be customized further. I still have my Cobb from 7 years ago, but I'll switch to mhd at some point. I don't see any reason for jb4 piggy back (sorry).

-dci - I love my dci for the sounds more than anything. However, some tests have shown that it increases wgdc vs. a closed aftermarket intake setup (e.g. Like the one ecs sells, forgot the name) but I still love it enough not to remove it. And super cheap.

-in my humble opinion, do a fmic before dps. Why? Because on the stock ic After 3-4 seconds or back to back pulls on the highway...errr track,, your car will pull timing and you'll lose all that extra power you think you've gained. You can spray meth to work around this as well if you don't want an fmic, but that's just silly. Also, as you increase the boost and power from the above set of parts, you'll find out real fast if any coils, plugs, injectors, etc can't keep up. This is a good setup to drive around on for a bit and get a feel for your newfound power.

-when your feeling good about the above, throw some dps on. Ceramic coating is not necessary unless your building a balls to the walls machine.

-spark plugs - stock plugs are completely fine with the above combo. No reason to switch to ngk until you start messing with E85, meth, higher than 21psi boost with aftermarket turbos, etc.

-oh, and get an rb pcv valve. And stay on top of basic maintenance.

Have fun. Stay safe. Avoid the cops. Peel out.

Oh yea
Hundred percent agree
But I've seen tuned cars have stock turbos never changed until 120k miles
It's all dependent on driving.

MHD is kind of popping lately tbh
But is it better/nearly the same as JB4?

Ummm, MHD has been out for a couple years now, and yes, IMO it's better and no, not nearly the same, and I've had both.

Honestly this opened up my eyes a little
Did some research on the MHD
I might actually look into it.

[TEC]

Honestly, I feel you need to re-research most of your entire guide.

I wouldn't opt for a piggy back over a straight ECU flash/tune. I would say MHD to flash a custom tune is a MUCH better option. You will see that a lot of people are selling their JB4's to go this option.

You don't need ceramic coated downpipes. The stock pipes arent ceramic coated either. In fact, most of the ceramic coated stuff out there isn't that great for heat reduction...its not worth the extra change.

The Mr5 style intake is a much better solution than the DCI's. It actually brings cool air into the engine as opposed to heated air.

Wagner intercoolers are okay. If the reason you would recommend them is because they gave you a cool lanyard and a discount...okay. I personally would recommend the VRSF 7" HD intercooler over the Wagner.

[limitdown]

The subject should be changed to something like, "bolt-on mods I'm doing to get near 300whp".
I just dyno'd above 600whp and I would not dare claim to know anything about tuning. The only thing I've ever done with tunes is flash custom tunes made by Dimitri/BQ and Ken/Wedge. Other than that, all I've done is paid other people to slap parts on my car.
MHD is so far ahead of any competitors. It's constantly adding new important features. For 6AT guys, you use the same device and cable to flash xHP. I sold my Cobb and JB4 right after going MHD. Read the full MHD thread on this forum and you'll understand why most big power N54 guys have gone MHD-only.

[Mit_Boost]

This is even less helpful than the severely outdated N54 Tune Comparison Chart


There's several tuning modules and bolt-on brands that can get the job done besides what was listed here.

I had to go back and reread the date on this thread multiple times...reads like something created ~10 years ago when there were hardly any aftermarket parts available and people knew nothing about the platform.

Some serious coldness to the Noob around these parts. No need to attack those who are new to the platform because you know more.

I swear some people here come off sounding like straight d*cks, no need for that.

Educate the guy, you have the knowledge....maybe he should've used the Search Engine but still there's no need to sh*t on the guy simply because he did it the only way he knew how.

You guys have so much knowledge to share and you could be a bit more gracious in helping folks which goes a long way.

Couldn't have said it better

[Barefoot-335is]

Yeah, I am wanting to start tuning my 335is but I'm older and have been in BMW's for 20+ years. I know before you start making it faster that you need to bring it up to date.
You need a good foundation to build on, you don't build a house by putting the roof on first.
I have done:
Coils, Injectors, Carbon Clean, Plugs, OFHG, Waterpump/Thermostat, next will be Serpentine Belts and Suspension. Oh, I have added a Charge Pipe, LOL!
I will then start with the go fast goodies.The ass end on the 335is is so squirrelly adding more power would just make it worse.

The fastest N54 is flash only and doesn't use a JB4. So if you care more about performance than bells and whistles, then people should be looking into a flash only tune, not a JB4 regardless of backend flash you want to apply.

Downpipes, well, have your pick as long as they fit properly and dont leak. So this will highly depend on reviews

Wagner FMIC is not "the best" FMIC out there. Its a good FMIC no doubt. Your post neglects that there are other FMIC that perform better than it or equal with it.

You have other FMIC like VRSF 7" HD (which I highly recommend), and ER FMIC etc

I know plenty of cars with a sealed intake setup that perform better than cars with DCI .

- BQ

As far as I know w the JB4 owns the N54 1/4 mile traps record at 140mph. It's true Vargas recently passed the N54 1/2 mile trap record by running 170mph without a JB4 but he has a lot of other piggybacks on the car that are trying to serve the same purpose a JB4 would.

For anyone serious about performance the JB4 has a ton to offer not possible flash only. Not to mention free custom tuning support, resale value, a lot of "fun" features, and continued development.

If you're writing a guide, start with the "Why" and good OEM/stock resources first.

For example, link to the reference guides on the N54. Break it down in simple terms, cause some new owners have been limited to "intakes and ebay coilovers" until now.

Why do you want a tuned N54 powered car?
Is there potential with this platform?
What are some of the pitfalls?
Suggested part resources? How do I find a part #? RealOEM, what's that?

Recommended maintenance? How do intervals change?
Why can't BMW design a gasket to save their lives? I have oil leaking from x...: Link to DIYs, part #s, etc..
Oh no, misfires? Help! How to read codes? Sparks/Coils/Injectors replacements? : video by Cobb is a good start, then add additional resources. Colder plugs, diff coil options (Delphi/Eldor), info on index of injectors, etc...

Piggyback vs Flash tune? What is a JB4 backend?
What is an OTS flash vs pro/e-tune?

How do supporting modifications aid?
- Charge pipe? Why?
- BOV vs DVs? Why?
- FMIC? What? Why?
- Downpipes? Why?
- Inlets/Outlets?
- Fueling? HPFP & LPFP? PI?
-

What is street logging? How do I read this?
I have a CSV, how do I read this? Whoa, what is datazap?
Parameters?

Pump fuel? E85?
I used to own a Subaru, "souped up to Stage 8.5", is it the same with my $10k 335i?

Start answering these questions, and provide hard evidence with links to tests, not opinions/reviews.
