Alpha-N tune installed on M4

[Icy]

I found the price of this tune:

Alpha-N is well respected German tuning company.

They offer this for 799 incl. Tax + 39 is installation.

It is a piggyback from what I can see (Chiptuning Box)

Isn't that the same box Turner is selling?

By Alpha-n they mean they eliminate the map sensor or it's just a cool name they borrowed?

Only major question I have is how this tune affects motor longevity? Is there a reliability hit being taken?

I was referring to Prad as measured on a MAHA. Look at the Prad on the MAHA graph and you see that it's not a 10-15% loss since the MAHA uses a different Method to calculate/measure Pschlepp (DT loss).

As I wrote in my post, the Prad (whp) on the Alpha N tuned car is 439,1PS and Pnorm (crank) is 520,7PS

A stock car measured 453PS at the crank on the same dyno.

520,7 - 453 = 67,7PS gain from the tune at the crank


I then said that it probably also was correct to assume that the stock M4 at 453PS had a similar difference on the Prad (whp) vs the Alpha N tuned car.

439,1 - 67,7 = 371,4PS (whp)

So, what I said was that the Alpha N car had 439,1PS at the wheels, which probably should correlate to 369-379PS at the wheels on the stock MAHA dyno run.

The whole point here was to figure out what Prad (whp) the stock car had measured on the MAHA, since we don't have that particular dyno sheet.

Could you point out where the flaw in the math above is?

I too thought it was the type of tune. In fact, it's the name of the tuner, Alpha-N (silly if you ask me).

Hi ....

the company name is ALPHA-N performance ... For the reason because we have grown up with Alpha-N tuning.
Our main focus is on carbon ..
Our piggy backs we soll with the Name EVOX system ...

And the BMW M4 had 450HP stock

There is an additional control unit. (Piggyback)

Maybe take a while to enjoy the standard car before mapping?

Do you have the dyno graph for the stock car as well?

No offense but that's just your opinion. People coming from high power applications to this car are going to want more power right away. If you just sold an ESS 625 E92 for instance.

With that said I'm leaving my car stock software for a while :P

How exactly was this helpful to the thread?

My point was to get used to the standard car so that you will have a point of reference to enjoy the remap at a latter stage.

Having owned a few M cars, I find the standard output is almost too much for the public roads. Re-map only makes sense to me for regular track use.

Pretty sure every tune takes some longevity away, just some more than others.

[ASAP]

Yeah... no one is flashing this car.

Thank you

BTW, your tune has a very nice power gain and a great shape on the TQ and PS curves

Even for circuit tracking, I'd rather keep the engine stock for reliability reasons. I'd rather focus on my driving to improve my lap times.

I think the tunes are mostly sought after by the 1/4 mile and 60-130mph racers.

Every thing I have read to date seems to imply these S55 motors are coming out of BMW pretty close to max performamce. So far we've seen a few piggyback and claims of a few extra ponies but when you start to peel away Dyno charts we see non conclusive data on actual gains. Bhp vs whp vs diff dynos vs unlce Leo in his home garage with a multimeter(ok, that was a joke but you get my point). Piggybacks going for anywhere from $1500 - $2500. No flash, re-writes, just tricking the ECU! Seems to me, voiding warranties for such little gains might not be a good idea at this point in time. I was in a beta jb4 m4 couple weeks ago, it was nice but frankly my butt-o-meter told me, not much diff to get excited about.

On pump... I doubt it would make a serious difference. With E85, it will make a massive one.

Agreed, it seems to maintain the characteristics of the stock engine.
