Race Chip XLR is a pedal box. Doesn’t effect tune just throttle response. Most get GTS. I have not had any deterioration in transmission functionality.

As hilsman stated. GTS Black and RS are the engine tune. XLR is pedal tuner.

Most are getting the GTS Black.

does racechip clear CEL if i do downpipes?

If it does, that'd be truly impressive since it has no digital interface to the car's ECU as I understand it. If that's the case, I'm gonna go with 'no' on that one.

The JB4 can clear *many* faults that'll surface as CEL but not all. E-Sys is, however, able to clear any that I've encountered so far but boy, that's a complicated setup and process to use repeatedly.

I got myself a pedal-box for both my RS7 and my E63S since I felt they were necessary. I've not found that with the M5. Have you had much interest in them for the F90?

It doesn't unfortunately.

AFAIK, JB4 do a full ECU reset every so often.
But since the crackdown on that capability, they disabled the function to clear the CEL.

Pedal box is a hit and miss.
Some prefer it, some don't.
I have it in my G30 540.
IMHO, it is not necessarily needed, but having it is a plus since you'll have control on your pedal sensitivity.
And with the new App and Gen2.1 chipset, you'll be able to set a preset on which Map on the GTS Black and which pedal setting on the XLR to the driving mode in the App.
So with 1 click, it will change both the XLR and GTS Black simultaneously.

That's nice being able to attach pedal response to driving modes. It became a 'set and forget' in both of my experiences.

I hope the JB isn't repeatedly issuing whatever RESET amounts to; that's an uninformed decision if it is. It can still read codes and it's cleared a good chunk of the minutia but codes like implausible boost targets require something more. I'd previously thought only BMW dealers had the 'secret sauce' for the faults that triggered a CEL but a friend of mine who codes professionally showed me the E-Sys trick and it happily wiped the slate clean.

I ran a sprint booster on my F10 550 and it made a huge positive improvement in throttle response. I considered it a must have for that car.

Fortunately. the F90 does not seem to have the same issue with laggy throttle input so I don't feel the need to put one in.

In another couple of months...just as I fully get used to the crazy acceleration...I'll decide between JB4 and GTS Black and take it up a notch. Looking forward!

Cost is not the primary concern. I just want the best performance with least hassle and risk to the engine. There's still so much conflicting information out there. I'm hoping that an ideal solution will seem more clear i8n a few months or so.

Agreed on the Pedal Box. Regardless, that's one cool concept and a great device where needed.

On the piggy choice, yeah--I don't how to help folks choose. I was close to buying a RaceChip to provide that firsthand comparison but ultimately couldn't bring myself to deal with the hassle of uninstall<->test<->reinstall<->test<->compare<->document.. mostly because I'm so happy with the JB4. My suspicion is you'll be happy whichever way you go.

The installs for the base JB and RaceChip are comparable (identical?) because they do the same thing in the same way so that's not a differentiator. The JB4 is more advanced and can use OBD II stats to influence its runtime tuning among many other functions; it can also take direct control of the electronic wastegate (EWG) but, combined, these require more wiring gymnastics but, even then, the EWG connection uses the same base install principle as the first pair of wires. Only the optional but recommended ODB II connection requires a bit more work.

E2e customer service probably goes to the RaceChip. Burger stand behind the product and will replace it if it goes wrong in a heartbeat but as far as guidance, recommendations, etc., that's all forum-driven and insufficient if you want plug'n'play. That said, the device does *just work* so you could argue it's plug'n'play but 1) why bother if that's the preferred path and 2) the moment you get the app, the 'play' part draws you in because of the sheer configurability... and we're back to the lonely learning experience.

All of that said, I've had Lambo and McLaren drivers giggle in my passenger seat when I show them 4th gear acceleration using map 6 @23psi flat boost on pump gas--it's literally laughably powerful.

[Pimpsy]

Thanks for that input.
As a former mechanic I'm not intimidated by the install. I am though concerned that racechip doesn't seem to put out honest numbers in their literature and I'd rather pay triple cost than end up with buyers remorse.

I'd also probably rather have 29 features I'll never use rather than miss out on a single feature that seems useful.

I'll probably end up getting the full BMS package although I have no intentions of installing DPs or any other performance improvements.

Again...looking forward to learning more while I work myself up into the requisite buying frenzy.

That pretty much sums up my attitude and approach.

The other benefit of the JB4 is this wonder called "RACE GAS"--you have to try it (104 octane unleaded is your target). The result is almost as pronounced as the difference between stock and tuned. Most other tunes can't easily take advantage of it. With the JB4, it's as easy as opening an app and selecting the appropriate map.

checking in- hows reliability?

what map/ fuel are you running daily?

Had a Pedal Commander on my RS7...desperately needed. I don't think it's nearly as important on my M5 but installed it anyways and it's an improvement based on my preferences. Between the Racechip GTS and the pedal commander, I'm good, have had zero issues.


Last I checked, Racechip doesn't have a version compatible with the M5.

Hmm, gotta check with Germany on that. They should have it.

No CEL? I thought these were triggered by overboost which is how the RaceChip and JB4 work??

Incorrect.

No CEL's ever.

A JB4 *can* cause a CEL, e.g. too lean or implausible boost targets. However, you typically have to be tinkering with more advanced settings. In its regular map 1 or map 2 modes, I've never personally seen a CEL.

Related: the JB4 can also clear them from within the phone app.

CEL should not be an issue .. ran piggys on two separate F10 M5's w/ zero issues.

The only thing I remember was a DTML on my 13' M5 which I cleared without it ever returning.

CANbus is the real difference maker. I'm not sure a tune not attached to CANbus can stay 100% invisible unless it runs a lot less power like BMS Stage1 is set to.
