Tuning options (N20)

Greetings!

After a heady amount of research, I may be picking up an X1 xdrive28i for the wife. One of the first mods (post break-in) will be a tuning option. Has anyone on the forums looked into or installed either of the following?

1) http://www.turnermotorsport.com/p-25...20-engine.aspx

2) http://www.turnermotorsport.com/p-16...20-engine.aspx

3) http://burgertuning.com/N20_BMW_performance_Tuner.html

According to Hartge's website, their application is directly for our X1. To me, this is the better of the options - despite the price difference.

Opinions?

Hartge is too expensive for what you are getting IMO.

I am planning to install the BMS Stage 1 after break in. I confirmed that the BMS solution addresses throttle response.

Does it? I was under the impression that that delay people are feeling was transmission related. That would be great if it addressed the issue, though.

What I wonder if how these tunes affect gas mileage.

Throttle response is tuned by BMW. Throttle response is the worst in ECO PRO mode to help with gas mileage. Throttle response should be better in Drive and best in Sport mode.

I emailed Burger to confirm that the stage 1 tune addresses throttle response. Because it is drive-by-wire throttle delay can't be completely eliminated.

Mileage is unaffected unless taking advantage of the increased power.

Here's a user review of the install and performance of the piggyback tuner by Burger on the X5. I had been monitoring this thread when I still had my X5 before deciding to trade in for the X1.

http://www.bimmerfest.com/forums/sho...d.php?t=654757

I'm personally going to refrain from upping the boost on the N20, as I plan to keep this car LT and want to wait a couple of years to see how this motor holds up, given its already running ~15lbs of boost in stock form.

I would agree if the unit were boosting to unreasonable levels, but i don't think that's the case. An additional 3lbs of boost won't make a grenade out of your motor. The reason for a revised tune (for me) is for throttle response first and foremost. Maybe a bit less lag and perhaps a small amount of power up top.
These units are made to mimic the characteristics of the stock tune, albeit with a small tweak - so it's not jarring on stock components.
Looks like I'll be a guinea pig if the sale goes through. That said, I would trust Hartge over BMS, but that's just me.

Hello, my first post here. I recently bought a 12/12 X1 xDrive28i (N20 engine, original 245HP). The car felt strong enough, but as it came with the M Sports Package, I felt like it deserved more power

Snooping around in foruns and the Net, I came around the Hartge bypass module. At the time, Turner was selling it for the F30 (new n20 engine 3 series), and I figured, if the engine is the exact same, it should fit the E84 as well. I contacted Hartge to confirm, they asked for my car's VIN and the response was that it would fit without any issues. The module I am saying is this: http://www.hartge.de/e/bmw_motor_6079.html

Well, I bought it at Turner (through Internet), received the module in Brazil and had a specialized shop installed for me. I also installed a set of sport H&R lowered springs, and the car looked amazing.

The torque gain is amazing. In second gear, feels like it will burn the tires. Responsiveness improved as well. The module was expensive (US$1250), but I felt like it worth it. Here, in Brazil, no one has an alternative, and even if it had, I felt more comfortable choosing a well known tuning company, such as Hartge is.

My car has now 7K Km, and it went last week to the dealer's regular oil service. Car stayed the whole day there, and they didn't detect the module. No problems with the car's warranty, then.

I see now that Turner has a cheaper alternative (http://www.turnermotorsport.com/p-25...20-engine.aspx), but honestly, I don't know this manufacturer (aFe Scorcher), and I would not risk using this one in my new e84. Seems they are not Bimmers specialists. Hartge, on the other hand, is.

Hope this helps!

Does Turner still offer the Hartge tune? The link no longer works.

Great stuff!

Did u find a noticeable difference in throttle response? Maybe sharper?

Looks like they don't anymore. Unfortunately, buying directly from Hartge is way too expensive!

Johanness, I also installed the Sprint Booster, so yes. But the module itself only shows its power if you put your foot all the way down. The combination with sprint booster seemed very good to me.

You installed the Sprint Booster into your N20 X1? Interesting! I think you may be the first successful install that I have read about.

I sure did, and it was VERY straight forward to do so. What others have reported? Installation is as smooth as it can be

I can post pictures later on, if you want

Sure. If you would like to post pictures it would be nice. I did not mean to make it sound like others have tried. I do not believe I have seen anyone else even attempt a sprint booster install. Every site I saw with the sprint booster for sale did not list the X1 as a supported model. I had a feeling it would work without issue, but since you are the first I have seen report it working I got excited.

N20 Tuning

I have a 20i N20 X1 which i picked up my car in July 2012 and running 5,000km today in Asia Hong Kong.

Ordered my tunes from Terry when running 3,000km and installed at 4,000km. Tunes is worth it as it really minimised turbo lag (20i has great turbo lag @ 184hp on N20). Running it for over 1,000km and have no regret other than manual reset of throttle and/or disengaging power in car for tranny behaviour.

If disregarding the tranny behaviour and throttle lag after computer learning your style of driving behaviour in a city mode, the BMS tunes are worth investing as it does not affect fuel consumption and it really helps minimising turbo lag.

I've made a compliments to Terry personally wishing him to develop the Stage 2 tuning for N20.

All I see are upgrades for the diesel models and for the 28i, does anyone know if the Burger piggy back would work on the X1 35i as well. I heard you can get close to 350hp output with the Hartge system which is an additional 50hp over stock. SICK!

It is different hardware than the N20/26, but Burger has tunes for the N55 35i.

Follows some pictures of my beloved X1 28i N20. The black in the hood is just a removable protection I put because I am often out on highways. Wheels were painted black and I added a set of H&R springs to lower the car a little. The Sprint Booster is shown in one of the pictures. Very easy to install, there are several how-tos on the Net showing how to do it. Original front grile was replaced with a black mate one. Additionally, there is the hartge module installed (no pictures there), which boosts the power to something around 295 HP.

Spoke to my dealer who is pro-mods today. They do have an N20 tune in their inventories with a "Coming Soon" status. Just so everyone knows. My guess is the Dinan one is a few weeks away.

I've had the BMS Stage 1 installed for a few weeks now. This tune has made the 28i so much more drivable. Driving in D is like what DS use to be (when you need it) and DS is on steroids now. The power delivery when going full throttle is not as smooth as my N54 335i was, but it feels almost as fast.

According to the folks on the F30 forum, BMW switched to the electronic wastegate on the N20 engines July 2012 (like the N26). BMWVin.com and RealOEM are generally pretty accurate and it seems that all US X1 28i have N20 and not N26. Sticker under the hood shows ULEV II. Either way, this greatly simplifies the BMS Stage 1 install/uninstall which doesn't require engine cover removal and takes less than 10 minutes.

Can't wait for Stage 2!

marcoaf which sprint booster did you get? I read online that the E82/E88 version will work on our cars. Nice ride BTW and the wheels look sweet in black.
