Cool Hartge N55 F30 335i Engine Software Tune Yields +56HP / +59TQ for F30, F10, F25

BIMMERPOST
     Featured on BIMMERPOST.com
Hartge Engine Performance Upgrade - F30 335i F10 535i F25 X3 35i (N55 Engine)

HP gain = 56 hp
Trq gain = 59 ft-lbs


The Hartge 'Engine Conversion' is a bespoke tuning module that plugs in ahead of the engine computer on the wiring harness. It has factory-style plugs to connect in-line with the water temp sensor, fuel rail pressure, turbo boost pressure sensors, turbo wastegate valve, intake camshaft sensor, 12V power and ground. The module then sends a modified signal to the engine computer allowing it to increase boost by varying amounts depending on load, engine speed, and other factors.

All of the factory safeguards remain in place, including overload protection, warm-up protocols, and the engine tuning is unchanged below 70% throttle to preserve all factory driveability and emissions certification*. One of the key advantages of this type of 'piggyback' system is that it is unaffected by factory BMW updates and service. If BMW updates the computer software to fix any small bugs or issues, the Hartge performance upgrade is not lost or overwritten. This is key on a new model like the F30 because BMW is constantly releasing small software updates. All of the factory diagnostics and service access is retained.

This item fits the following BMWs:
2012+ F30 BMW 335i - Sedan
2011+ F10 BMw 535i 535i xDrive
2011+ F25 BMW X3 xDrive35i

Looks promising, I like all the safeguards they have built into it. Only time will tell though...

Check out the engine section on F10 5 series board..someone just posted review on it.

Expensive yes! But it's probably the only choice for now!

This one? OP says below 3000rpm it just feels the same as stock. <3000rpm is exactly where I'm at when I'm driving normally....

You might wait for the BMW PPK, rumored to be out by the end of this year. The PPK in my car gives more torque in the driving range from 1500 to 4500 RPM, no questions on the warranty and no problems.

^^ what is the expected HP increase with the PPK? In the past the gains are only up to 335is specs which is only 320hp.

Turner is willing to do $1500 for the Hartge tune when i emailed them. Still a lot of money for a piggyback system but looks like the only option at this point.

You can NOT compare JB to Hartge. Hartge is in a completely different league as a Bmw tuner in Europe

Yup, you found the threat.

My thinking is if you look at JB4 N55 stage 1 tuning, it is not getting much more tq out of the N55 so I suspect there is not much room to work with or wait until someone else with Flash to see if there is room to be extracted.

For anyone interested, look into the Dinan stage 2 upgrade for the n55. It bumps power to 355hp and torque to 401 lb-ft.... There will eventually be a stage 3 as they mentioned that on their site. 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.

Aren't there cooling issues with the dinan? I can attest that the 335i m-sport with the ppk, pe is no where close to the power of the is even though they match up on paper. I would mos def do ic upgrade. I would just wait it out or do turbo upgrade.

I agree. A bit overpriced but you get what you pay for with the hartge and dinan tunes, especially the ppk. Maybe they are a little pricey but they are worry and hassle free. Yeah you can easily get a better tune for cheaper, but in my experience cheap stuff is usually cheap for a reason, it doesn't last as long and stuff is constantly breaking. You don't go to Kmart to buy your awesome set of golf clubs...

is this true in fact? so if you lease a car and do this bmw will have no problems with it? im assuming if they are ok and it doesn't void warranty, it shouldn't even raise an issue with anything. if a motor blew because of this tune, you get a new motor for free no hassle? is this true?!!?

How is jb4 not in the same league?
I would buy a burger tune any day over this, based on my experience with an n55 jb3.

In my experience, fuel economy is unchanged. Although, having the tune makes it much more tempting to be more aggressive with the throttle, which in turn will decrease fuel economy.
