I still say the best bang for the buck in coding is enabling the anti dazzle lights. So very useful and fun to watch

What's that? I haven't heard of "anti-dazzle lights" before.

ah. but you would need automatic high-beams for it to work. Pretty cool!

Yes High Beam Assistant (or whatever they call it).

Went back to the oem tip today. this always happens where I make some change on a car or something and I end up returning to stock. The M exhaust tip was bothering me, looked too big.. I recently saw a 320 at a dealer lot and suddenly thought it was fine and then was reminded me of how I am a moron for doing this in the first place. So now, it is back to 'OEM' except that it was cut originally to put on the M tip and so it had to be welded back on. It looks fine and you'd have to put the car up on a lift to see but it sort of freaks me out for when I turn the car back in in 2 years. Anyone could see if it were on a lift that it had been cut and welded. The guy @ exhaust shop did a fine job but still.. A lot of people I know have said that their lease turn in was very quick and basic and that they do an exterior, interior and engine bay inspection but don't put it up on a lift. I wonder how true this is. In any event, I'm back to the ol' single peashooter and I like it but end of the day, I wonder if I am going to get dinged at lease end of if anyone will even notice.



Moral of the story is that I am a dumbass

Ah crap, wish I hadn't seen this. Just today I stopped by the exhaust shop to get a quote on doing a Magnaflow exhaust/muffler only and my plan was to do a single M tip. Original plan was to do the dual tips like the 328 but the peashooter has grown on me (also would've had to cut my bumper or buy an entire new one) so decided on the single. Anyway, after seeing you going back, I'm wondering if I should just re-use the oem tip? Can you elaborate what you meant by it looking too big? You interested in selling it?

[Kafkaesque328]

Actually yes, I am selling it. Just haven't posted yet. Cleaned it all up, its ready to go. I don't know man, it's just me being a crazy person and always changing my mind about things. It's aggressive looking, I just thought it looked a little big and sort of misrepresented. It implies modified exhaust but the exhaust is stock. If I was ever going to go all the way I'd just run a new aftermarket exhaust for more sound, etc. But yeah, if you are interested in buying it PM me

I need to get some coding. Is it hard to get?

[Kafkaesque328]

Greetings and a happy labor day to you all. I posted a video of a few more acceleration runs. I don't think I'll do any more because I (A) feel ridiculous when I try to do them, (B) the one-handed iPhone cinematography is unsafe and (C) the only way you can break the 6 second to 60mph barrier in a 320i is by going balls deep with Stage 2 etc. Since I'm 99% sure I am going to get a different BMW when my lease is up, I don't really want to dump anymore money, time or effort into the car. Stage 2 is tempting but I just doubt I'll do it.

Couple of 0-60 runs and a 20-100mph highway pull in Sport+, after the coding was done. What is funny is the quickest 0-60 time I have gotten is 6.13 sec in Drive, comfort mode w/traction control off. Sport+ seems to give a slower time overall time even though shifts are quicker.

[BMWJester5oS]

^^^^ Great Video. Need to order my BMS Stg 1 ASAP after watching that....

[XenaBimmer]

I've got BMS stage 1 coming in the mail for the 320! Hoping it'll help with power. I mostly drive my 328, but drove the wife's 320 this past weekend on a road trip and couldn't deal with the lower power, thus instantly ordering the stage 1 on Monday!

Please provide feedback between 328 stock and 320+stage 1 after tune is installed.

Will do!

[J.Rizo]

bumping bc theres so much good info for those looking into 320/328s.

its been a few years since the op got his car, these are now even MORE of a great deal if you get them cpo (for those in the used car market).

don't forget about the huge aftermarket support there is now. btw full m perf aero can be had for about 1.5K. people in socal should go to ikon motorsports in city of industry for the m perf aero, they color match and are great guys. def recommend.

[BMWtight2me]

Kafka only went stage 1 BMS on his 320. It's a measly bump tbh. I tried multiple tunes on my 320 and the only stage 1 that will bring it to 328 performance is the dinan stage 1. (Considerably faster than BMS's stage 1.) That being said the only way to make the 320 best the 328 is with the jb4. This will take adding a dowpipe and intercooler for proper safe gains.

If you plan on doing this to either car '28 or '20, expect very similar results. Once they're both set up like this they can both safely climb to 300 hp / 300+ tq territory.

The 320 has a slightly higher compression ratio so it actually gets higher gains from less boost. A 320i at 18 psi is faster than a 328i set at 18 psi due to the higher compression. However the 328i can boost better on lower octane due to its lower compression (especially in the heat). Make sure to log your car with any tune if possible so you can make sure it's not running lean. Adding a meth kit for either car should reduce the risk of high temps. May also give the 320 the upper hand over the 328. I'm going meth next summer AND WE SHALL SEE. If you go 320 be mindful of heat, octane and ign timing. Really both 320 and 328 owners need to be careful they're not running lean.

If you plan to tune it like that (Jb4 and bolt ons)... the 320 is the bang for the buck. But if you can find a super cheap 328 go for that! Or just get a 330 it's more fun than a stock 328. I drove one for about 30 days this year and it's a better engine...

I bought my 320 in '15 for like 30k and it's been treated to the msport kit, coilovers, full bolt ons... the works. No 320, 328 or 330 I've seen can keep up with it and I'm in a f30 car club with 50+ members. Only spent 30k on the car and got hooked up with the parts for a great deal. It's a fun route for any f30! People mistake nice looking f30s like one as an M because it's so low, and custom looking, plus with the high boost and catless dowpipe it peels off and sounds insane.

Just keep in mind, regardless of whether you go 320 or 328, it's an n20... take care and keep an eye on your logs. And if your in the 320 stock to map 5 at first, it's adaptive and will get faster with each bolt on. The rest of the BMS maps are fixed boost and may damage your engine more. You can't really go wrong with either he 320 or 328 if you tune them properly, just don't get caught up with the BMS stage 1 like Kafka did, if your goal is at least stock 328i power. Just go off of the psi. They have the same engine with basically the same set up... BMS 1 adds only a few psi to the utterly neutered 8 psi the 320i is set to from factory. This means the same BMS 1 tune will have a much different effect on the 328s.

Curious which 4-banger f30 you choose. All great choices if you decide to mod. And get the 330 if you plan to stay stock -- it's pretty sweet out the box.

You re-opened a debate from '14 -- interesting to analyze it now after so many have moded their n20s. Hopefully Kafka jb4s or gets and hot ecu tune on his new 328i, would be a fun write up.

Holy ancient thread revival, Batman.

He's right, simple stage 1 on the 320 isn't a big deal but I quite enjoyed it and it still transforms the car in terms of power.

I am still just JB+ on the 328i. No plans to go bigger currently but have been looking into MPE

Kafka -- wassup homie. Long time

Im feeling a Yuccas hut n20 tuner meet thread... Could be fun to see the new 28i especially with an MPE upgrade! Or it might be worth seeing first hand what others have done exhaust wise before pulling the trigger.

On the real though, on the topic of pushing these n20s. I think your set up is honestly plenty. It's surprising that BMW already cranks the stock 28' to 18 psi. I dont think that pushing them beyond 20-23 is safe long term anyways. My full bolt on jb4 build is more quintessential to the 320i imo, a lot of bang for the buck, but for very little with the 328 and a set up like yours you achieve very similar results. More interesting than the MPE in some ways would be for you to get a catless DP. I know you tried one before but it's a whole different beast once your pushing at least 18-20 psi through it. More effective gains and sound than the MPE and less money. Id do the MPE too the heh.

Curious to compare a 328 and 320 with full jb4 build outs. I'm going to put a meth kit on mine next and I wonder if it will give the slightly higher compression more power with the same peak boost and hold in timing. Was going to wait till next summer, but this heat wave is making want to pull the trigger.

Kafka have you considered a larger intercooler with this heat or have you not noticed it bogging down at all during the day?

Yeah I feel like the power is plenty. I drove the car directly after driving my friend's 340i and while the 340i is obviously more powerful and pulls harder and more smoothly in the upper rev range, the JB+ 328i barely felt slower when I got back in my car. Its brought my 0-60 down to about 5 sec flat on a good day. The car pulls pretty hard and I haven't had any reliability issues or heat soak even with the insane heat and humidity, so no, stock intercooler remains. If I was going to buy the car @ lease end, unlikely, I would upgrade the charge pipe for the long term. MPE is again, the only mod Id really consider at this point. Besides 35% ceramic tint and JB+, I have no other mods.

I had Dinan S1 on my car, and still thought the 328i was noticeably stronger. Dinan rates the S1'd N20's output at 236 hp/233 lb-ft on 93 octane fuel, so it should (theoretically) have similar power but less torque.

On that note, I just test-drove a 330i M-Sport (the only 6MT one in L.A.), and felt like its power slotted neatly between the 320i S1 and 328i...
Torque was noticeably quicker to arrive, though - lag down to the low tenths of a second, almost better than a 718 Cayman S 6MT I looked at recently with the new lag-fighting throttle/turbo tech.

Closed deck engine, better weight distribution, firmer shock damping, etc make the 330 the no-brainer choice if you've got the $. Even the new RFTs didn't produce a jarring ride like the old ones, but it remains to be seen if they break away as progressively at the limit as PSSs and the like.
