Sports mode on S35i

[solidgold]

There are 2 ways to switched to Sports mode.
Option 1 - Toggle the gear shift stick to Sports.
Option 2 - Select using a switch that you can toggle from Normal to Sport to Sport+.

So what is the difference when you use option 1 or 2. Will one activate the M-suspension and the other doesn't? What if you do both at the same time?
Any idea?

not really sure, but when i go to sport mode from the button and put the gear in S mode i feel the shifts are much better than just putting the button in Sport.

when you shift over to the left on the shifter, it goes into sport mode. It will then shift and higher points than if you just left it in drive. In drive it shifts up very quickly, but in sport mode it holds its shifts much longer. More for more spirited driving, but still reasonably relaxed. As soon as you move the lever forward or touch the paddles on the steering wheel, it switches to manual mode on the dash and you are now controlling the shift points and it stays in manual mode until you move the shifter back to the right. As far as the sport and sport + button is concerned, it controls how the steering, and throttle feel, and if you have the adjustable suspension, it adjust that also and hunkers down. When you switch to sport and sport +, the steering feels heavier and more sporting, and the throttle does also. Combining the shift lever over the the left and the sport +, makes for the most spirited type of feeling. When you have it in sport+ the traction control is turned off as you will see on the dash.

My understanding is that sport mode on gearbox is just the gearbox being sporty only, putting it in S mode sharpens everything up, including putting gearbox in sport mode. On the other Z4 models, (sdrive 23, 30, 35) anyway
There's been a long thread on DSC and TC. You can't turn TC off completely, but you can DSC

I too figured out that the combination of the sports mode button and moving the shift lever do different things and that sports+ and the shift lever in "S" mode give you the sportiest driving while still in auto-shifting.

BTW, I did RTFM but it's nice to hear it from other owners too. This is a discussion forum after all

yes, you are correct.

dam all cars that i raced i never put the gear in s mode, it was only sport +.
thats ok since i smoked all of them :P Corvette C6, masaratti GT, camaro SS.

did anyone try vs the new boxter S with PDK ?

I traded in my 2007 C6 6 speed manual with Z51 for my 2009 Z4 35i with DCT.

Based on owning both cars, I can say that the Z4 35i with DCT is not quite as fast as the C6. The Z4 is damn close to the C6 0-80 mph, but still a few tenths of a second slower, but over 80 mph the C6 400 HP begins to show it's advantage.

The only way the Z4 would beat the C6 is if there were some variable involved. They are close enough under 80 mph where if the other driver is a putz, or missed a shift, the Z4 might eeek out a win, but to "smoke a C6" probably means the other driver was half asleep or something.

The BMW claim that the Z4 35i does 0-60 in 5.0 seconds is a joke. If this were true the C6 would be waaaaay, waaaaay ahead of the Z4 at 60 mph, and that just ain't the case. The C6 does 0-60 in 4.1 - 4.2, which puts the Z4 at about 4.3-4.5 seconds. Proven by Motor Trend test drive too.

Agree, the C6 is one fast car while the Z4 is more of a touring car, IMHO.

We agree the C6 is fast, but will have to agree to disagree about the value the extended leather will bring at trade-in.

I agree to disagree. That's what nice about living in the USA, we can disagree and stay alive and free. Don't try this in Iran.

I had the c5 and c6 z06, they both were wickedly fast. The z4 is not in the same league when it comes to power. Not even close. But in every other measure it is superior. Interior, ride, comfort, quality, and enjoyablility.

Still not broken 2000km yet so will wait till then to floor the pedal and see if it will surprise me. I have also checked on a few ECU mods and first on the list is BMS JB3. I know some of u have tried it and posted quite a few threads on the performance after the ECU maps.

Any one actually did the 0-60mph timings after the re-mapping? Understand that the added 70bhp and 400nhm torque will give a very linear boost from standstill to red-line. Very little lag below 3000rpm. Is that true?

Any overheating issue? Some folks told me that you can hardly run a couple of laps around the track before the temperature overheating sign lights up.

HPFP (Fuel pump) issue after remapping?

Good question! I'm planning on hitting the track next month (just passed 1,000 miles) and I guess I'll find out if there's a heat issue. I have the JB3 but have only run on 91 octane (Calif). It does add more power but this is dependent upon octane. I haven't tried any 0-60 times but I'll post when I do.

Cheers

hey solidgold! i just had my hpfp replaced at PML. Not sure if the JB3 has any part to play, but the engine check light issues started after I went for a 3hr sepang trackday. The car was practically stalling every other laps!

[Marc45]

sq,
Did you try running with the jb3 disabled?

[rmorin49]

HPFP failures, here we go again.

the 370z has the overheating issue, not the z4. The 370 forum is loaded with lots and lots of complaints about it.

That sounds bad. Did they replace the injectors too? Which map were you using when you did your laps at Sepang? Also, did the temperature warning lights came on?

alan64, the z4 s35i has overheating problems too and im speaking from personal experience.

I ran on map 5, map 1 and also with jb3 disabled. not able to get a single clean lap before the dreaded reduced power mode came on.

soildgold, pml only changed the hpfp, did not replace the injectors.

On paper, based on HP, the C6 is in a "different league", but the superiority of the DCT over the C6 transmission and immediate torque in the
Z4 narrows the gap substantially in the 0-80 mph range, to a point where by driving the 2 cars you absolutely do not feel there is a gap of 100 HP. It feels more like a gap of about 30 HP.

Over 80 mph is a different story.
