What do you mean by 'amazing'? I can easily get a remap which will make the car 'feel' faster, but won't actually be faster, simply due to changing the peaks & troughs in the power/torque band.
In theory, if you got 900bhp from the chip in your e46, then you should be able to get the same increase on the Z4M, as they're the same engine.
Haven't seen any 'real' proof that any chip makes much difference over stock - and whilst some dyno's claim to have increased the power by x amount, I've yet to see one perform better in the real world - including one e46 which was actually slower around Castle Combe with the claimed 25bhp extra power than he was the fortnight before without it.
I've even seen some claiming to have increased power by 25bhp, reduced emissions, increased economy and reduced where the peak power is delivered by 1000rpm, which makes you wonder why BMW didn't do it.

Hmmm, so i have skeptics.
Well, you obviously don't know what I know.
Take a trip over to the m3cutters and have a little read.
My M3 is standard apart from a rolling road remap from Evolve.
My bhp and torque figures are not claimed, they are actual.
(even though i have not "claimed" anything.)
I have the top speed limiter removed.
Friend of mine has an E92 M3.
After my road tune I now pull away from him during acceleration and top end.
Could not do that before. We have even swapped cars and the same happens so you can't say it's the driver.
Yes mine is unlimited, yeah yeah, but the difference is incredible, he even says so.
How do you guys get on with the new Focus Cosworth?
Nailed one of them this afternoon actually.
He's a mate as well.
He was well gutted.
Intact just to set the record straight.
My boss has a DB7 GTA.
he starts to pull away from me around 140 ish. But then it's just slightly.
Top speed runs I have had an indicated 185, that's as far as the speedo will go.
Satnav gave me 176.
So I am happy with that.
All I wanted to do was to spread the word.
In fact add the Evolve carbon air box as well and make the Zed sound like a CSL
Oops,
Sorry forgot.
Z4M is not as quick as the M3 to start with is it.
Ahhhh well,
You pay your money you take your choice.

It's not a "feels faster"
I only wanted to spread the word but sorry for doing so.

I know what I am talking about.
Your are right to be skeptical.
Evolve are the leaders in tuning the M3 engine.
Give em a call, speak to Sal.

Z4M must be slightly quicker due to less weight than an E46 M3. Would think the Z4M would also have slightly better aerodynamics as the frontal aspect of the car is smaller than an M3?
Mapping E46 M3s is very contentious stuff, there have been some unbelievable debates/arguments on M3cutters, with contributions from the tuners themselves. After hearing all sides, I'd go with Evolve every day from what they say and from what their customers say (bit more low-down torque, smoother power delivery and yes, gains of around 20bhp more). I have heard of some tuner's maps that make the car feel faster by changing the throttle mapping so that pushing the pedal down 50% actually gives you 80% of the power (similar to Sport button mode) so when you try your car after the map you think "Wow, massive difference" and in reality the car is no more powerful at all.
I have also heard of some cars being slower after a remap :|
Talk of remaps is common on m3cutters, but I've heard very little (nothing in fact!) over here. If my car had no warranty I might well be tempted, and Evolve would get my cash.

Fixed it for youdaz05 said:
Maybe if all these remappers/chippers offered their 'best' map/chip to an independent tester or maybe for a magazine feature, who would then put them on the same car, under the same test conditions, and see what the difference really was, then I'd be less sceptical (but I'm sceptical from experience).

I love these types of threads - so funny - but to the guy who said about the better aerodynamic shape of the z4..I think I read somewhere in the past that the m3 has a lower Cd than the z4..very suprising but nonetheless the z4m is quicker imo!
The drag coefficient is only useful of you know the frontal area of the vehicle as well.doofus4000 said:
For instance (very basic explanation using false figures for illustrative purposes), an M3 might have a cd of 0.25 and an frontal area of 3m² which would be the same frontal drag as a Z4M with a cd of 0.3 and a frontal area of 2.5m².

Seems the coupe is lower than the roadster which is higher than the m3..cut these from a site;
2005 BMW Z4 2.0i :dunno:
Drag coefficient 0.340
Frontal area 1.91 m2
Cx 0.65
2005 BMW Z4 M Roadster
Drag coefficient 0.370
Frontal area 1.92 m2
Cx 0.71
2000 BMW M3 :thumbup:
Drag coefficient 0.330
Frontal area 2.09 m2
Cx 0.69
2006 BMW Z4 M Coupé
Drag coefficient 0.350
Frontal area 1.91 m2
Cx 0.67
2005 BMW Z4 2.0i :dunno:

You need some drag to provide a bit of stability to the front at high speeds, so I'd expect the M to have more than a non-M.
Although those figures show another reason to get the MC over the Mr
So, the MR has more drag than the M3 and MC, but is lighter than both, so we're no further along the route to which is really quicker

Yep, these threads are fun. Annoyed I missed it.
Honestly, OEM you've got 106 Bhp / Ltr. (go compare). That really is the top of tree for an NA engine. Look at the mad expense for an CSL (Alpha N tuning, cams, exhaust headers and CF airbox) for just a few ponies more. No electronic tweaking alone is going to get better results, thats just common sense.
Don't think our cars are lacking in the trouser department really.

I think the gains of a remap only is debatable (which means it could be down to poor ecu tuning that can be fixed by resetting the ecu)
if you want to produce a more HP but gain more noise the tried route of alpha N, carbon airbox, cams, exhaust, race cat etc is there. lacking a lot of the components above is not going to get up there and if you went that route and is prepared to kiss any warranty goodbye, you might as well slap on a supercharger.....
now we're talking about real gearbox busting gains...
otherwise, just a remap prolly gives negligible gains although you could get the speed limiter raise which would be a valid reason in itself.
dun do it... spend it on a nice dinner instead........at least the emeories will be real ;
