Evolve gains 46.8 wheel horsepower naturally aspirated on an E46 M3 S54 with their carbon airbox and Alpha-N tuning for a total of 326.8 wheel horsepower

good job guys!

This is at the top of my list when I eventually pick up an e46 m3!

tempting...hmmm thanks for the link Sticky. i think i'm gonna hold out a bit for the MaxPsi turbo kit though...

and i agree with everyone else...although my M is an 05' it never ceases to amaze me with its performance and i never EVER get tired of its aesthetics.

I am building at the moment another Evolve n/a S54,same setup as above plus cams and head work.

We will see how much this one puts down...

WOW! Sal will be tuning ANOTHER cam'd S54?!?!?!

Make a build thread here ASAP!

Do you have any baseline dynos or data?

Is a customer car that has worn cams and rockers,no baseline.

Disassembled it this week and today the customer gave green light for the build.


Build thread like on my n/a S62 monsters follows,Flip...

Really want to see this...

There will be several built head and camm'ed S54's with @evolve tunes in 2013. Mine will be safe for repeated trips to 8,500+. @normcaldwell and I delivered the Cams, Supertech valvetrain parts, and DLC followers to the machine shop during the holidays. The head is already hot-tanked and disassembled. And the OEM head/valvetrain have already been flow benched for baseline data. Should be a fun year for S54's.

SO. MUCH. WIN.

I wonder what NA numbers we will see....

VERY nice results guys! I'm such a S54 fanboy....

LOL You and me both buddy.

Thanks Mike!

This is probably a stupid question. What is the advantage of Alpha-N...especially in a car that sees mostly track time?

Well, everything. You target tuning based on expected airflow.

So is Alpha N a more precise means of measuring airflow? I know it ditches the MAF but how often do MAFs fail in an NA engine? Its not something I feel is a necessity to delete.

I had a great post somewhere explaining this but I can't find it. I would recommend searching.

Nothing really came up on here that answered the why. Or at least I did not see it.

I wish I could give you a more technical explanation, but I just don't think I know the concept well enough to suffice. What I can do is tell you the benefits that I've personally had after having, stock tune, Evolve MAF Tune, and Evolve AlphaN Tune.

First thing is that I am now able to use an Airbox that has much more massive air flow that the stock MAF is not capable of metering. The nice perk is that I get to use a sexy CF Airbox that sounds out of this world when paired with the S54B32.

Second thing I noticed is the feel of the throttle. Evolve has done a pretty darn good job with their throttle mapping for both MAF and AlphaN. With AlphaN, it took what I felt with the MAF tune to another level. This is the only car I've ever driven that is as close to throttle-cable setup. It feel as if the amount of throttle input I induce is in a 1:1 relationship with what the throttle bodies do. So what I noticed on the street is much more predictable, manageable, and natural throttle control. Whether it be heal-toe, holding throttle around a turn, on-off throttle transitions....it's just instantaneous, yet smooth and predictable.

With the MSS54, there is an integrated barometric sensor. So despite the extremes in weather condition and slight deviation in elevation that I confront, my car has never skipped a beat. It has driven 100% reliable and predictable in literally all four season with a drastically wide range of temperature.

Another nice perk of deleting the MAF is that now I can relocate the IAT sensor to somewhere that is more accurate and consistent in reading. In the stock S54B32 MAF, the IAT is integrated within the MAF sensor. The problem is that the MAF has a tendency to heat soak, tricking the IAT into thinking that the temps are higher than they really are. This is not very ideal for power output and consistency. With the MAF delete, I now use a IAT relocation sensor. Evolve has scaled the IAT within the DME maps to read 100% accurate and precise. With my own data logging and when up to speed, my IATs are always within a few degrees of ambient. In my opinion, this just shows how reliable and consistent both Evolve's Intake is and their choice of IAT location.

So AlphaN as a whole gives you the opportunity to experience a few small things here and there, that overall can have a nice change in the driving experience.

Hopefully that helps share one side of the story. If you have any specific questions, I'd definitely be willing to be as helpful as I can.

well said

Flip...99% of what I was looking for. So I'm still waiting for the last 1%...anytime now...

But I get it now. So basically Alpha-N is mostly pointless until you get the CSL style airbox. On the "flip"side, getting the CSL style box and not getting Alpha-N leaves some gains on the table and is not required.

Going OT...but I had wanted to do headers and a 3.5" BW style exhaust with the software. Then at some point add the CSL box. So I am trying to figure out if software with the exhaust system will be a total waste.

Thanks!
