Burger Motorsports stage 1 tune... OMG... 70whp 50wtq!! Dyno video

[Spinny02]

could anything else have have caused the CEL? Anyone else get the CEL? I am about to pull the trigger but i don't want to get a CEL!

Still not sure what to do take it off and stay stock... Honestly it doesn't bother me.

There are million things on our cars that can cause this, starting with bad fuel, low battery charge, changes in airflow, changes in exhaust flow, relays, vacuum, etc, etc.
I get the same error without the tune.

I'll keep an eye on it the car will be pushed this weekend weather permitting if it comes back during "testing" or anytime soon ill pop it off and take it to the dealer but I'm not uninstalling something I just stuck on.

I got the cable and got it all sorted out. I've got about two days of run time but no major flogging…weather has been crap here as well. No codes so far…

What do you mean by resetting the car? just curious if you did a fault code reset.

Curious about resetting the car as well.

I just turned it off and turned it back on and the car had no lights and was running fine.

This doesn't remove the vmax limiter, right?

No it does not. It is not an ECU tune.

Its crude tuning for the moment. You are simply tricking the ECU to under boost and request an extra 2.2 [stock map], 3[custom] or 4[if you wanna risk it] PSI over stock configuration.

There is no monitoring, adjusting A/F ratios, anything its simply telling the ECU under boost requests more load.

[Spinny02]

Is there anywhere that BMW can read the actual psi reading with the added 2.2 psi? If I go in for a warranty issue?

With how advanced this ECU and motor is it's certainly possible . But it is a certainty that , air flow , AFR , fuel flow , ignition advance ,engine load, etc will all be out of normal values . So it will be very easy to tell there is a modification by BMW if you were to have a warranty claim .

I mean the values would be screwed up but they have no way to prove you did X to the car, again unless there is some kind of super secret logging going on, you buy a code clearer and remove it and take it in and shrug your shoulders the onus would still be on them to prove you did something to it. And you could promptly follow up with a lawsuit if something major happened.... Personally after using it I don't think its that unsafe especially running 93.

And actually those ratios/values would be fall back into place upon re adaptation to the removal of the device/ clearing of codes.

It's called shadow memory.

They will most definitely know. They may or may not deny a warranty claim but if they chose to do so you'll have a long up hill battle.

Good thing I don't keep cars more than a year then.

With the tune removed there is no way for BMW to know it was ever there. These same basic techniques have been used by BMS on over 25,000 other N54s & N55s without issue. It is a very detail oriented business though. So while the Stage1 TMAP approach works nicely for 2psi on the s63tu that doesn't mean it works for 6psi. A different circuit board, sensors, logic, etc, are required as the Stages and power gains go up. With the N54 certain Stages also require a supporting DME flash.

Stage1 is limited to 2-3psi with the s63 (depending on octane) as this is the reasonable range of the DME to compensate for fuel trims and long term timing trims. The DME will see wider boost variances on its own running on a 40 degree day vs. a 100 degree day, 91 octane vs 94 octane, etc. Beyond the Stage1 levels more precise fuel and timing control is required as they have recently developed for their n63 Stage2 tune. No word on when there will be an s63 Stage2 upgrade kit released. If one is released it will connect to the Stage1 system with extra sensors, a new board, etc.

Since Stage1 does not have CANbus access BMS also suggests purchasing a Bavarian Technic cable ($179) which lets you read/delete potential hidden BMW codes, do more extensive logging of knock and AFR if you're worried there might be issues there and want to put your mind at ease, etc.

I've been shocked to learn other tuners are selling the same basic TMAP based tune for $2500-$3000. Hopefully more people realize this BMS Stage1 is doing the exact same thing, more with the simple user adjustment and logging offered, for a fraction of the price.

OP on the dyno email BMS the DRF dynojet files, I'm sure they would love to include them on their site.

I just don't foresee us getting a true tune, my hope dwindles daily not to mention all these companies posting big crank numbers for their "tunes" when in reality the engines are already coming highly underrated which gives the illusion there are some Super gains when really they're marginal when piece building if not less... I mean look at the IS-F thats been out since 2008 and nobody has cracked that ECU and they still have no forced induction options.

Right now just from reading the best setup anyone could do in my opinion would be:
GruppeM Intake
exhaust
supersprints catless downpipes
forged wheels lightweight wheels
BMS piggyback

And thats it lol

Glad to see M5 owners sipping on the BMS juice... my 550xi ran 12.9 stock on BMS stage 1 i run 12.1

our stage 2 is almost done looks promising should take the 550 cars in to mid to high 11's.
