Makes sense to me. Additionally you get a better 0-60 w/ the xDrive right out of the box.

I never WOT from dead stop. When playing, usually just hard acceleration from a roll or 1/2-2/3 pedal from a dead stop (just enough to maintain full traction). I'm more into the instant throttle response and the sensation it provides. Ear to ear smiles.

@ the time I ordered didn't anticipate doing a tune. Traded a C7 for it. Corvette had plenty of power but GM's wonky A8 left me driving it as a blvd cruiser rather than playing w/ it as I tend to do w/ performance/sporty handling cars.

For me the M240i isn't too far behind the C7 (for my type of playing). I just have to apply more pedal w/ the BMW to get the same sensation I got from the C7. Bimmer 8 speed is way better too.

Anticipating this Dinan to put me even closer to the C7 w/o the tranny issues. I'll likely be .1 slower to 60 and .5 or less in the 1/4 (based on published numbers for both cars). Not that I'll ever verify those numbers IRL.

Next car will have xDrive

I am seriously contemplating this, after I do the exhaust.. I know traction will be an issue, but have to wait till I have summer rubber back on to find out how much of an issue it is bone stock.

I have a 6spd rwd and it's been fine in the snow with the winter tires - however the winter tires will break loose even on dry pavement in this cold weather.

These cars do surprisingly well in the snow compared to some other rwd cars.

Chomping at the bit for the M240 exhaust and mid pipe.....

So I said a few weeks ago I would get this Dinan Elite and Dyno so here you go. First run is with the Dinan on bypass mode so not turned on. The next few are the dynos after the install. Took a run or two for the car to adapt to the tune. So now just trying to see if how much my butt dyno can tell the difference. =)

[varkdriver]

It's great to see someone take the plunge and report back with dyno numbers. Looks like a great tune as you would expect from Dinan. With that kind of power, hooking up my be the biggest issue. Please report back with more of your impressions as soon as you can.

Looking forward to hearing from you!

[jpnh]

Excellent

Thank you very much for posting results

Numbers are impressive but quite a bit different than what Dinan posted

Is there anything that would have contributed to a difference that you can think of?

Altitude
89 octane fuel
Other?

Pretty close to Dinan's engine dyno results considering an estimated a 15% drive train loss. Thanks for sharing!

[jul2412]

Nice results! Very tempting to install on my car

[USA-RET]

My rough numbers using Dinan's and BMW published HP and Torque numbers, I came up with around 366WHP and 421 wheel torque.....so the actual Dyno numbers of 364 and 410 aren't too far off.....although a bit more torque would always be welcome.

As Dinan states, each car is a bit different as are testing conditions.. Still the Stage 1 is a real kick in the pants for the car's performance IMO.

25 more lb ft of torque is very noticeable in a car, now double that. Wowser.

Yeah, I noticed that too but I'm not complaining. I only use 91 gas and it was in anaheim so not sure what the altitude was but it was high humidity today because it raining here and there in So Cal.

Awwwww man, I missed this today lol. Car is looking clean!

[Joe240]

Correct me if I'm wrong, but don't dyno jets under estimate power a little? I only ask because my xDrive stock ran 308 at the wheels with Insoric.

Dinan numbers/charts are at the crank so apply a 12-13% drivetrain loss (or 15% if you like) and the numbers shown at the wheels on the dyno line up pretty closely to what we report. The one relatively large difference is this was done with 91 octane whereas our testing was with 93. The maxes actually line up nearly perfectly (a bit surprising given the octane difference)... the baseline though is a bit low compared to what we had on our averaged test vehicles. Again, octane can probably explain that difference though.

Regardless, looks like the OP has a strong running car and I hopefully the butt dyno approves --- with a +70 HP / 55 TRQ on the dyno sheet I think it would be hard not to. =)

Soooooo

How about that exhaust

Still looking at end of the month?

In theory, yes. May be the first week of April but yeah...

DynoJet brand dyno's are always higher reading dynos.
Mainly performance companies use a Mustang or Dynodynamics for building the software and use the Dynojet for advertisment.
Of course this argument goes back and forth but "tuners" will admit this and say that dyno jet always read high.

Read this link about VF explaining their 2 dynos being used and why.

Thanks schnell for the link. Definitely informative.

Agreed. The baseline is interesting as it's showing a little less HP power than a typical stock M235 on a Dynojet Torque is where I'd expect it for a B58, perhaps dropping a bit quicker than what I've seen. Maybe it was the 91 octane on that run.

Dynojets are pretty damn consistent whether you're dynoing on one LA or NY assuming the operator is correcting for standard conditions and doing some smoothing. You can't manipulate much of anything on a Dynojet and it's an extremely simple dyno device.

What's interesting is the Dinan Stage 1 M240 Dynojet plot, shape, and numbers look eerily similar to the Dinan Stage II M235 Dynojet plots out there. The B58 still takes the cake in heat management though.

Dynojet's don't read "high", it's just the numbers it calculates. That's it and it doesn't mean the number aren't legit.

The advantage of load-based dynos like a Mustang dyno is that you can vary the load to simulate real-world conditions like going up a steep grade in a tall gear and low rpm (high heavy load), brake the dyno down to make the motor feel like it's towing, etc. By varying the loads, the tuner can better tune the motor to keep itself from blowing up in real world conditions and idiot driver situations like going full throttle at 1,500 rpms with a small displacement gasoline turbo motor in 5th gear.

Dynojets are great for measuring all out power. They're not good at all for tuning.

Yeah, N55 overheating in my 435 and buddy's m2 is real

Ok, how about DynoJet reads higher then a Mustang...because they do read higher then most brand dyno's
