328i tuning options

Hello from a new member! I have been perusing the E90 and F30 forums for several years, but never bothered to register.

Having recently graduated from an E91 318D, whose ECU had been remapped by Heinz, I have started looking into various tuning options for my new F31 328i M Sport.

My natural preference is for remapping the ECU on the N20 too, but am not too keen on having this detected by BMW. I know that both Heinz and Kempower have cracked the ECU on F engines, but doing this job would require dissolving the glue that holds the ECU unit together, downloading a new custom software onto the chip and putting the unit back together, which I am certain the dealer could detect even without advanced diagnostics.

This takes me onto the piggyback options available in the EU, which I do not particularly like.

From what I can gather, Steinbauer tuning boxes of the Steinbauer, ACS and Hartge variety control a few more variables than some of the cheaper options and work via optimised injection. Some of the cheaper boxes just jack up the turbo pressure to 1.4-1.7 bar, which I would be reluctant to unleash on the engine.

What would you advise me to do? A custom ECU reflash (but potentially losing the warranty on a brand new car) or going with a tuning box (which I am sure advanced BMW diagnostics could also detect even after the box has been unplugged)?

Not familiar with the different euro tunes. But JB and Jb4 are the most popular here in the US. Lots of vendors, including us ship international if you would be interested in giving it a try.

Mike is telling you the truth.

More tunning (canbus, ewg), e85 and great support: BMS.
Start with stage 1 and later upgrade if you like.

Racechip, Active Autowerke are good options with easy tunning.

Thanks to you both. Have looked at a bunch of JB4 reviews -- will also check out the Racechip.

Thanks, everyone.

Right now I am leaning towards http://www.br-performance.be/en-be/c...011/4110-328i/. They do a proper ECU remap customising the torque and performance figures to a customer's specifications and have come clean about 'invisibility issues'. For the time being, their tune stays invisible to BMW but they cannot guarantee that for the future. They also offer an extended warranty on the drivetrain and transmission courtesy of a French insurance company. Oh yeah, and they are the only TÜV-approved tuner in Belgium.

This is good enough for me. A proper custom tune that boosts performance and torque to figures I would get from a piggyback, removes the speed limit and offers a solution to the warranty issue. To me, a tune is far superior to a piggyback though I am not dissing those who have opted for the latter.

Anyone out there with a BR performance tune on the N20?

How does it offer a solution to the warranty problem?

I will have to get more details, but I think a French specialist insurance company takes over the warranty on the drivetrain and transmission if BMW declines warranty on those parts as a result of the tune. This carries an annual fee and can be extended to five years.

Rest assure, you are in good hands. There aren't many posts about them and are all over the other bimmerpost forums: http://f80.bimmerpost.com/forums/sho....php?t=1065967 for one

You are lucky to be in Belgium, many of us (directly or indirectly) had our ECUs shipped to BR Perf to have the ECUs unlocked. They seem to be very busy the past few weeks though, give them a call before going down.

Not sure how that can be undetectable. Everyone says the ECU has a flash counter. It's bound to happen though eventually someone cracking the codes. But yah too bad they are so far away. LOL.

You can send them ECU, and they can remap it for you remotely.

I considered before to do this, but I'm happy with present piggy back solutions on the market as I have one myself.

If I still had my F20 116i, I would send it straight away, as power difference is massive what they can extract from it!

But for N20 it doesn't look like that, and it's still on current piggy back range.

I have decided to go with them. Had many of my questions answered by the owner, and the warranty solution is also kinda crucial for me.

Think about it: even if BMW detects the tune (which never happened with my previous car), I will have a properly tuned engine whose potential drivetrain and transmission malfunctions will be covered by specialist insurance.

Have only 700 km on the clock - will do this after 5000 km.

Will keep you informed.

Cool!
Pls get on their Dyno before and after !
We look forward to your review on the N20 engine
There's a forum member who has BR-P stage1 already on his Z4 28i who had JB4 previously.

Hey guys i've got a question, do I need to dyno tune my car after installing cai? Or will dyno tuning it void my warranty?

Don´t see how a CAI could void your warranty.

My previous tuner told me not to bother with aftermarket filters -- just change the OEM filter frequently. Don´t know if aftermarket cold air intakes increase performance, but you get a lot more -- a 20% gain -- out of custom remaps.

I have read somewhere that BR Performance can really customize the maps for different modes. Planning on asking for a really economical Eco Pro mode, a sharper Comfort mode with better throttle response, a properly tuned Sport mode with 1.4 bar of boost and optimized throttle response and a full-on ´Race´ mode in Sport plus, if possible.

We´ll see if they can do that..

I've always been a pro BMS tune guy and think there's some solid evidence now--I ran a 13.6@101 tonight with just a Stage 1 tune and on stock run flats; I'd say not to bad for such a cheap and easy mod!!
I've been running the tune now for over 10,000 miles flawlessly
