My dyno isn't until Sat. should have some info one way or another by then.


Edit - Just checked with COBB about the dyno and the guy has been sick the last couple of days and not at work. So it may or may not happen tomorrow depending on if he comes back to work Sat.

Ok here's the results from the dyno. Temps/conditions couldn't have been closer to the day of the reference dyno. (good news) Maybe one degree difference. Vehicle is in fully stock configuration except for the Dinan stage 2 ECM flash tune.




For those who think charts suck, here's the skinny.

All wheel horsepower went from 270 to 289. which is a difference of 19hp, (it really was a difference of 20hp, but the computer is rounding off the numbers) and torque went from 280 to 327, a difference of roughly 47 ft TQ.

So 20HP / 47TQ increase to the wheels, and that's as measured on a Mustang dyno. Dinan gives the tunes increases in flywheel HP, saying that it will get the vehicle an increase "up to 350HP and 400TQ" (flywheel HP). In my particular case that translated to an increase of 20HP / 47TQ on the AWD drivetrain. Keep in mind Dinan tunes their stuff more conservatively than most other aftermarket tuners.

Also something to note is the lines for both the HP and TQ acceleration curves. The tech there pulled up the runs with the N55 Stage 1 and compared them with the Dinan flash tune. Dotted line is the N55 Stage 1 runs.

Thanks for posting. I have a couple of question
1) What is JB1 baseline? 270hp looks high for stock. Only 10% loss for AWD looks too little.
2) I posted I felt differences with DINAN stage 2 at 3500tr/mn and looking at your graph torque gain is around 70 and hp 50 at 3500tr/mn. It looks what I felt.

Juste received my spacers 15mm and 12mm today, still no cable yet for flashing the TCU...

The rears just bolt up as usual.

There are X1 specific kits from KW (both V1 and V3 varieties), but they're only sold to the German market as far as I know. I'm currently trying to get my hands on a set through my usual guy here in Calgary. If that doesn't work, I'll try and hit up some of my contacts back in the UK.
do you have a pic and size of the sleeve or a link to which one to get. i got some megan coilovers and it looks to be too short and too small so im looking for the sleeve you mentioned.

Better called N55 Stage 1, that's just what the dyno guy put in the computer (JB1).

270 would be high for stock if the car was actually putting out around 300 fwhp. We suspect the engine is a bit under rated and actually putting out more. 270 seems to be in the ballpark for these stock. Also the Xdrive seems pretty efficient. Compare some stock numbers between a 335i and 335ix

CIWS, thanks for sharing this valuable information.

The Dinan tunes give you piece of mind in regards to warranty. The BMS tunes definitely give you more bang for your buck.

Yeah I'd say the results fit pretty squarely with their claim, and the car is running good, no issues,it's quick and no speed limiter

The two minuses for Dinan are their cost and the fact you know their tune is still conservative for what the engine could do. So other tuners should offer potentially more pwr/tq.

Pluses are you don't have to mess with hiding or removing it before you take your car to the dealership. The conservative tune levels should keep any parts from breaking prematurely, but if they do you also should be covered for the first 4/50 with warranty. Plus any improvements like Stage 3, etc you would only pay the difference from money already spent.

With the Dinan tune they call it "up to 350HP/400TQ" So try those numbers using an 18% drivetrain loss and see where they end up.

So to throw this out, the N55 is putting 270hp/280tq at the wheels and the n20 is putting out 238hp/261tq at the wheels (n20 dyno). How is it then that the N55 0-60 is .9 seconds faster in 0-60? CIWS is getting the bmw claimed 0-60 of 5.3 so we know that side is accurate, but I haven't seen 0-60 times of N20's to know if they are at 6.2s or not.

If the N20 is doing 6.2s at best, I can't see 32hp/19tq making up this .9s even with the ZF 8HP requiring an additional gear change. Is it an average hp or torque that makes the difference?

Just trying to understand the 0-60 difference between the two if hp/tq don't seem to explain why.

You can't just look at peak numbers. The torque curve makes all the difference. Look at where the torque kicks in on the N55 vs the N20. Huge difference.

Also one of the reasons the more important boost in Dinan's tune was the TQ level vs HP.

So.....I've read a bunch on tuning the N20 in my X1. I'm about to pull the trigger on the BMS Stage 1 tune, but want to get opinions on if perhaps there is a better tune to get for the money. I may also go for stage 2 when it is available, but won't go any further than that, as I need reliability since this is my daily driver.


Anyone here post 0-60 or 1/4 mile improvements in their X1 28i? If there is something like a half second improvement as the posts about the 328i suggest, I'll be pretty happy.

Thanks!

True, but the 35i lacks a 2.5th gear - there's an awful lot of difference between second and third, where I feel it loses at least a tenth or two, even with the wide torque range.

The gear range differential feels like (to me, at least):
1--2--------3---4-----5---6

I felt similarly with my N54 335i. 3rd and 4th gears were the sweet spots for me. I never really cared about 0 - 60. The car went from 60 - 100+ effortlessly.

I have the BMS stage 1 and believe it to be the best tune for the money (and so easy to install and remove). I will likely move to stage 2 once they release it. It is in beta now but they are still working out the details for vehicles with the electronic boost controller (basically all US X1s). Stage 2 will give more power, features, and safety (win win!).

So, would you say that the power increase is definitely noticeable? Any chance you've dynoed your X1 or measured 0-60 times?

I agree that the cost seems very reasonable, but only if there is a real improvement.....



Any down side? Drivability or fuel economy while cruising normally?

Thanks for your input. I really appreciate the feedback.

Power increase is definitely noticeable when you give it gas. Boost is increased by up to 3 PSI from stock and comes on much quicker (you can even increase to 4 PSI if you have 93 octane gas and you get the USB cable).

When driving conservatively, I have not noticed any change in drive-ability or gas mileage. This is how the car should have come stock, but I'm sure BMW has the EPA and other things to worry about. I will say that the transmission programming in DS mode is not ideal for the tune as at times it will rev higher than necessary before shifting. I generally leave it in D and paddle shift when needed. Most of the time D is just fine as the increased torque pays dividends.

Performance is just barely below a stock N55 35i IMO (I'm coming from a stock N54 335i and I'm happy), but you need to rev a bit higher than you would on the I6 for comparable power. I judge this solely by butt dyno. When passing on the freeway I hit 100 MPH quite quickly (have to get around car pool lane slowpokes in a short interval). 5th gear seems to be the sweet spot when passing on the freeway (was 3rd or 4th on the N54 w/6AT).

I'm averaging ~24MPG combined, same as I did before adding the tune. I can average 32MPG on the highway if I keep it at 65MPH and don't pass, 30 MPG at 75MPH. City driving however I only get about 18.5 MPG. A lot of traffic lights around here.

It's pretty much the same gearbox, isn't it?
Yeah, flipping between 3rd and 4th is where I'm at most of the time too. 5th for long stretches, but 6th is only for cruising, and 2nd is too far down to be of much use.

I'm sure the N20/ZF8 has more use of the low gears than the old six - hopefully they shortened the intervals and didn't just tack on the top gears as extra overdrives to save fuel.

It does have more use of the low gears. 8th gear is a true overdrive gear only useful for cruising on the highway (no passing power). The transmission shifts so fast you barely notice the shifts. This transmission is vastly superior to that in my E90 335i. It has been reported the X1 35i uses an updated version of the 8AT but I have no real first hand experience with it to compare. The 8AT and optional servotronic (deleted) steered me down to the 28i.

I only really use the paddle shifters to downshift when I want to be in the right gear before I mash the gas. I don't use the full manual shifting mode often (didn't on the 335i either). When I want to shift manually full time, I drive the S2000. The X1 transmission knows how to shift during constant acceleration better than I.
