For those who do not understand, it is ok. U probably cannot extract data from a graph from across the room.. or have no understanding of hp/tq crossover points, etc..

LOL . Assumption. GTFOH. BMW is a EU company who uses metric numbers mate.

Not sure if u or not.


How that chart is labled (what measurements they used) was secondary to my over-all rant. Which was the FORMAT of that graph is basically useless & retarded. With the proper x0vr 5250, a person does not even need to know what units they use... it a freak'n graph!

It just has to be to scale...! <--derp!



That is why I commented on it, since they obviously went out of their way to illustrate a marketing point(?).

[Robin_NL]

Anyway.

It started with this graph.

Imo it's very clear.

Agreed...what isn't clear?

[tojo_m]

Would this void the BMW warranty? Actually would they even come to know?
And what about the 0-60 and 0-100 times for the 335i with this tune?

[Alan l.]

Price drop from $1599 to $1299

Turner's website reflects this change. Still expensive but this is from one of the biggest and best Bmw tuners in the industry.

I had GIAC in my 06 A4 2.0T. It's full software not piggyback.
My MPG increased by nearly 2MPG, driving it the same way day to day.

However, you get these tunes for one thing, POWER.
When you want and use more power, of course MPG will go down lower.
If your engine is developing 40hp and 50lb ft more than stock, then it will require more fuel to develop that power.

I prefer Full ECU software over piggyback as power levels increase.
This is one expensive piggy. It does appear to be an advanced piggy system as it plugs into various sensors, seemingly to take over the readings the stock sensors are putting out. It takes time and money to crack ECU protection codes, and perhaps this company didn't want to crack the ECU or couldn't. ECU tunes also use the OEM sensors, but they are taking the sensor readings by which to adjust maps, instead of using sensor readings and altering them to make the computer think all is well.
If this works in a different way, then I hope the manufacturer chimes in and explains.

Simple piggybacks are cool for modest gains around 4-5psi. The JB+ is one such piggy and it works great. I've driven a 135i with the JB+ and the added power is very noticeable, very. It increased boost by 4.5psi. over stock. The price is but a fraction of this thing.
With CAN tool and JB+ the cost is only $329!
Excellent price for the added performance, and the tool allows you read and clear codes before dealer servicing.
If there was one for the N55 that would be ideal for those who want more power, but want to keep it safe. It really does wake the engine up when you want it, and drives like stock when driven normally day to day driving.

[fotios335i]

I think I'm going to try this out. I just worry about code clearing as this doesn't appear to have it. Will it leave a trace? There is not much info on it though.

I had a dinan stage 2 tune on my n54 e92 335i and never had a problem.

The stage two is like $2g's so a bit pricey, but they will match your warranty and BMW will acknowledge this tune and will still service your car hassle free.... Just saying.

This is NOT true. BMW and Dinan have fallen out of bed so to speak over the years and all BMW dealerships won't just overlook a Dinan tune if you have one. Even my dealership 3-4 years ago warned me about this, and so did the Dinan installer. Dinan and BMW are now competitors with their new performance product line, and BMW has zero incentive to place nice with Dinan.

Dinan's stage 3 tune on the N55 motor for the E90 model cars required $3000 in additional upgrades before labor/tax including an upgraded intercooler and oil cooler. Now you're looking at having to spend probably an extra $4000 on supporting mods, plus they charge an extra $500 on the stage 3 tune. $4500 for an extra 18hp? No thanks. Only if I was tracking the car would I spend the money on the oil cooler and intercooler (but not theirs anyway).

Their website incorrectly lists 2011-2012 335i sedans, but when you drill down on the view models section it says e90 only.

I think this aspect is a let down. I want to feel that extra power in the low-mid range at lighter part throttle....not just 70% plus.

We all have our own likes and dislikes for power band.
I actually like the idea of having the greater boost come on later.
It's more like turbo's used to be, where the big power came once the revs were up. To me, it's easier to modulate the power at higher rpms, and thus easier to modulate power in the curves.

With modern turbo's and direct injection, we get nearly all available torque before 2000 rpm, and in the N55 there is a LOT of it. These modern turbo's power output is like a diesel. Just look at the dyno's, huge torque at low rpm that then fades off as rpm increases. Nearly opposite of how turbo engines used to develop power.

Having even more at that low of an rpm makes it harder to get a great launch, as it just ends up in wheel spin.
Having the power increase above stock as rpm rises, imo, should give easier launch will better power modulation at higher revs.
You may find you do like it if you get that tune.

I think you might be confusing it? I think it means the throttle has to be mashed more than 70% of the way for the extra boost to kick in, but you'll feel it down low as long as you're flooring it.

If you've got good tires, traction shouldn't be an issue. I had no problem hooking with 380hp/420tq in my 2007 335i.

[tojo_m]

Do you think that the f30 335i PPK that is due to be released in December 2012 would require the car to have the higher top speed limiter? I ask because I ordered my car and although I found it to be pretty fast, it did not seem overwhelmingly fast. While ordering, I thought I could always add the PPK later in December, but I ordered the "no lines" which means I don't have the high speed limiter

If not, I guess there is nothing I can do to make the car faster, while still preserving the warranty. Right? (I don't think Dinan will work out for me since it won't work with the warranty direct's extended warranty).

Option 840 (High Top Speed Limiter) on the F30 is just:
- remove the TOP speed limiter
- add Summer tires

That's it.

So, there *shouldn't* (IMHO) be any real technical limitation to the PPK, rather a recommendation from BMW due to the higher capable speeds. I believe some folks had the e90 ppk installed without the 840 option (I also think 840 on an e90 added the extra oil cooler - correct me if I'm wrong).

In any case, we won't know until it's released. I know they said December, but my sources say don't bet on it until next year.

It looks great but I have always been skeptical about these sort of devices. Have a lot of you guys install them? Do they void the warranties? Can it really mess the car up?

Bad tune can blow a motor (very rare), or be blamed for other engine/drivetrain problems by your dealer and then denied warranty coverage. It's a risk; many uninstall tunes when taking it in, some don't care. Every dealer is different with how they handle it.

[Walt]

Does the 335 ecu log boost pressure? If so, the dealer will always know there was a chip or boost controller on it if they bother to look.

[fotios335i]

Just learned that the 70% throttle only applies to diesel engines. Full power is available after 1500 rpm. Just spoke with turner and they are changing it on the site. I'm going to test this and burgers.
