Z4M Evolve Automotive Tune

[VSmotorsports]

Recently we had a Z4M race car that previously had a tune already but he was looking for every bit of power he can get since it is a race car. The modifications it has are CSL Headers, Race Exhaust, AFE Filter, and 100 octane.
In the graph it shows the run before the evolve tune and after. The gains for this car are awesome because it is made all in the RPMs the car will see on track.

wow that's an impressive topend...but judging by the baseline dyno, the tune was a conservative one by a co based out in the netherlands?

More info please on costs, etc.

We are actually not sure who was the tune before but with that top end gain is big especially racing in a spec class.

The cost of the tune is $599. On a completely stock Z4M you are looking at gains of about 30bhp and 44 ft-lb. You will also get the top speed removed. If you have any other questions feel free to ask.

I can get the alpha n tune done and remove my MAF? this would be amazing for my nitrous setup(pull it back more and get even distribution). I was also wondering would it be possible to use the sport button for a nitrous tune(less timing)?

[pokeybritches]

Would the alpha-n tune allow the use of a carbon airbox?

[just2talented]

Im confused. Whats the power gains for the standard tune vs alpha tune? AND is this meant for race car applications only or is this going to be safe for stock s54 motors?

[arggg45]

OP- can you post a graph w/ AFR and RPM?

All an Alpha-N tune does is change the way that the ECU calculates the amount of fuel to inject through the removal of the MAF sensor among other things. Alpha-N uses the throttle position (Alpha) and RPM (N) to calculate the amount of fuel to inject as opposed to using the MAP (Manifold Absolute Pressure, as calculated using the MAF sensor, among other things) and RPM to calculate the amount of fuel to inject.

As far as being safe for stock S54 motors, I can't speak for the Evolve tune specifically, but there are plenty of people running Alpha-N tunes on E46M3 ranging from lightly modded to race cars.

Yes it can remove the maf but the sport button with a different tune(less timing) would not work.

There are carbon air boxes out that still use a maf but most would be maf less. For the evolve air box you would need to go maf less with the alpha-n tune.

Both tunes will be identical in gains and most likely not noticed on a stock car with just a tune. Many people move to alpha-n when they are putting race carbon air boxes on or forced induction. The main thing to move to alpha-n would be to remove the maf sensor. Both tunes are 100% safe just a difference on how the car regulates air/fuel.

Below is some information from evolve about the alpha-n tune

"AlphaN is where the air mass sensors are no longer used. Normally if they are unplugged the car will run under a reduced power mode, overfuel and bring up an engine management light with generally poor drivability. Our AlphaN upgrade is where we further develop the programme so that the S54 engine will run flawlessly without the air mass sensors. The overall smoothness of the engine is further improved over our standard ECU remap with the low speed drivability and general connectivity with the engine vastly improved.

This upgrade incorporates all of the features and benefits of the standard software which include the power increase.

Additional Information:
There is no issue of over fuelling but it is essential that the lambda sensors are working correctly (this is essential even without AlphaN) and you keep your air filters reasonably clean (which most enthusiasts will) in order to pass emissions testing.

The MSS53/54 control uinit is fitted with a barometric pressure sensor and recieves inputs from other sensors (throttle position, lambda, intake air and coolant) to correctly calculate expected airflow and control fuelling.

Air mass sensors are used mainly for emissions purposes where manufacturers are required to setup their cars such that they will pass regulations under the most strigent conditions. For example, the cars will need to pass emissions tests before release with extremely continaminted oil with air filters which are almost blocked. Enthusiast drivers never allow such things to occur and therefore air mass sensors are not essential."

Sure let me see if I can get a jpeg of that info.

interesting...watching this thread for sure

[VSmotorsports]

Here is the graph with afr's

[krnnerdboy]

nice! definitely confirms that our s54's like it lean up top! that other tune was amazingly rich on top...wonder what stock looks like

[VSmotorsports]

This one has 100 octane so it will be a little different if it were a street car running 93.

I just scheduled an appointment with Matt @ VS motorsports tomorrow morning to try out the Evolve tune. VS motorsports is only 20 minutes from my office so the close proximity, claimed gains, relatively low cost and a 30 day money back guarantee definitely make the tune attractive.

Like an AA/ESS tune...it can be customized to your mods and is upgradeable. I plan on having the map set for 93 octane, top speed limiter removed and the rev limiter bumped up to 8200-8400 (haven't decided yet)

An ESS VT2 is in my future; however, I am at least a year off so I'm hoping that this tune along with headers will fill the void in the mean time.

[flat_out]

Evolve's map is brilliant i run it on my car - power delivery is improved and the car just feels and goes much quicker..

[ZeD4Mr]

Nice. Please write a detail report on initial and after some mileage impression. I'm in the same situation as you; waiting for header to be installed and wondering about a tune. AA dealer is local to me and ESS has a handheld. Shooting for next spring/summer for ESS VT2.

Can we use the evolve-r cable to load the tune ourselves?

Hope you get before/after dyno's so we can see the difference on 93 like most of us will be running.

He just posted a review here if you would like to take a look.

Sorry there is no evolve-r cable. However you can still send in your DME and have the tune put on.

[BIMMERGUY91]

Can you do a custom tune for say AFE intake RPI intake scoop CSL headers and exhaust?

The tune can be done for many variations of different modifications. With those mods the tune can definitely be done. I see you are not local, so you would be looking for the evolve-r cable?


Also for those that were looking for alpha-n, there currently is no tune available tune for the Z4M from evolve.

[BIMMERGUY91]

I am not local but I thought that there wasnt an Evolve R-Cable for the Z4M and i would just have to send out my ecu? Do you guys have any dyno results from a stock car with just the tune. I was telling my friend about the gains on a stock car with the tune and he said he hasnt seen that on any S54 before
