for MB, it seems to be more difficult to get it coded as there is the other thread that OP wants to get into the engineering mode which is supposed to enable / disable the car's features & functions (similar to bmw) without much success thus far.

Sylvain, the piggy is usually an early adopting tune where the ECU has not been cracked... I have never used one once in my all my years of tuning my cars. Im not saying its not safe but here is basic explanation from one of the tuners on the M Boards:
Spacers will look good on the car but without the drop the wheels might look funny being so pushed out the fenders which will accentuate the gap visually. Supreme has tons of BMW spacers which I used on both my M5's and my F80 M4--- I think based on your pictures you could run a 15mm square setup (05x120 bolt pattern) and Supreme will let you test them out.
In a nutshell, a piggyback tricks the computer in order to achieve a desired result. It doesn't have direct control over engine operation, and it can not surpass certain limits/restrictions imposed by the factory computer. A proper tune is a much better way to go for the goal you have set.
A proper tune is as if the computer was programmed for the car to output those power levels from the factory without intercepting signals, etc.

The Internet is always the source--take a look for yourself, the JB4 is well respected. Vendors such as Dinan are far too conservative so many reverted to actually stacking the tunes--a little scary but the results speak for themselves.

I coded all of my own cars myself--the learning curve isn't that steep.

I use VF Engineering, its not going to win the internet battle of dyno sheets but I have tried several others and while they produce amazing numbers they can not sustain the type of driving I do on a regular basis. The heat soak issues with the M5 are very prevalent and while I had a tune(s) (no names here) it just couldnt deliver over and over as a **** star like myself expects LOL. EG: I would take my F10 M5 out (2013/2016) and rip it with tune 1 and 2 to about 150 mph and up and down the ranges in Cali heat circa 90 degress. But after 3 plus hard runs the car would heat soak it would become a normally aspirate 4.4 engine until the intercoolers did their work. The F10's have terrible cooling. But with VF I could run the car over and over; it may not make the peak hp that others did but it was daily usable tune that delivered over and over. Where I live I have the luxury of being able to really open my cars alot and for stretches at times that exceed 15 miles. So maybe these heat soak ECU tunes might be good for those in traffic but not for me.
I also used VF on my F82 M4.... prior to that I used OE for my E63 M6, E92 M3, and E46 M3. VF is probably better known for their R8 tuning and superchargers but have made strides in the BMW ECU world
Dean I have no doubts about the JB product (I believe the internet here LOL) but have never tried them as Ive always gone the ECU fashion, my post was directed to Sylvain the OP who I know. The fastest F10 trapping is Allmotor2000's at around 140 mph. I dont remember what tune he runs but he has a hell of alot of mods to get there. For tune only guys like me and as many as Ive done (30 plus cars with some having more than one) its just what I choose to do (ECU).

I tried Dinan once... 2 days later, I stacked my existing JB unit on top of it with a conservative additional boost to restore the power loss. That was the end of my foray into BMW ECU tunes...

Yup, understood, Vic--I meant only to interject with a bit of firsthand experience.

Sylvain I really can relate to this quote you did over at M5Post as I just picked this up for the summer... what a fun ripping car and I tuned it (GIAC) so its even more "peppy".
The E63 has a nice ride until the road isn’t perfect and then for me it got
Pretty harsh. The 911 GT3 I have rides better on the bumpier roads.
The F90 still rides sporty but more like a 911 which is sporty but still comfortable when the road isn’t freshly paved.
Best analogy is the F90 rides like my 911 GTS and the E63 like a 911 GT3 RS on bumpy roads.
Hope this helps

ha (at Dinan gains).... Ive never tried them once and knowing that they are almost too conservative I opted otherwise. But maybe thats how they can back up their "warranty" with low loss ratios due to non aggressive tunes? I dont even want the most aggressive one myself, just that tune that delivers a nice tq/hp curve gain over the usable rpm range.

BTW I got on the power this morning on my F90 M5 and it does feel noticeably faster than the M5....

Sorry I meant the E63s feels noticeably faster than the F90. Multi tasking fail

From what I am feeling.... I think both. The E63 really pushed you in the back of the seat... The M5 a lot less. Not sure why if the reviews and performance times are accurate.

We get our F90 delivered next week. Looking forward to playing with it a bit and we'll let you know what solutions we find for increasing the exhaust note. ANRKY wheels are being built for it as we speak.

I'm sure someone has put pressure transducers in the exhaust pipe sections before. Would be interesting to see the running display of the exhaust impulses as the various cylinders fire.
Seems like an interesting math problem to find the right length/shape of pipes to get the desired sound at a problem RPM. Tuning for ideal sound across a range may require active components (doesn't the Mercedes performance exhaust do this?)
If only one had the time . . .

The resonator removal has not been fruitful even with the F10 M5--(same engine) even with H Pipes... I fear the F90 needs alot of exhaust love yet again compared to the AMG magic.

I heard the DME catless DPs on the F90 the other day and it sounded decent, but I can’t soeak to the drone. Agreed that it’s still not as good as the E63 though....
