OBD2 Tuning of F15 X5

Came across this post yesterday and thought it might be of interest to the community. I am unaware of any other OBD2 tunes for our cars. Very exciting stuff!

For those unfamiliar, brentuning is an extremely reputable tuner for just about anything with 4 wheels.

We offer Stage ONE for $1,695
... and Stage TWO for $1,895.

Stage TWO for the n63tu is calibrated for downpipes/exhaust modifications
so you'll qualify as a Stage ONE customer if you're still running stock DP's.

What are the gains on the Stage 2 with Catless DP's? VF-Engineering

Biggest question is... I assume this tune would be detectable if taken in for service? Also, if stock tune is reloaded are there still "tracks" left that a tune was on the car? When I flash my ford ecu/pcm it resets the KOER (key on engine running) count, which obviously is a red flag to dealer.

If you're worried about issues with warranty and service then flash tuning isn't for you, better off going with a Piggyback.

I'm not worried, because I've decided that I don't want to do either. It runs great the way it is. I was just interested in how it works on the bmw. I am familiar with the ford pcm, just not the bmw's.

What are the gains on Stage 1 & 2 before we drop $1700-1900?

Curious as well ^ VF-Engineering

Also, very interesting timing that VF and Bren Tuning both released F series ECU tuning info within 24 hours of each other. Is this strictly a timing coincidence? OR did a 3rd party finally crack the ECU and now all the tuners are throwing their tunes in? I'm genuinely curious how that worked out.

Silververtu I'm new to the forum and just saw your signature. We have a (reasonably) similar car lineup. I own a 987 Cayman S and an F15 35d. The X5 and Cayman are both fabulous cars, the best of both worlds. Cheers!

I think OBDII won't allow to completely hide intervention. Even benchflashed cars can be detected and you have more control with benchflash

It's the small/nimble vs. big/muscular power car.

3rd party cracked it months ago. Foreign company that is signing on US partners as we speak. On Dec 24, they will finally allow partners to write tables. Thus all the tuners announcing their wares now.

From my understanding they can see how many times the ECU has been flashed. That normally would just raise suspicion. Now if you had the REV limiter increased along with other mods and something went wrong they'll have no problem blaming the modifications for certain issues. Lot of things to factor in but yes if they really wanted to see whether the ECU has been modified they can.

So since we didn't get an answer, I'll try to fill the void: as per other tuners Stage 1 is about 100hp and Stage 2 is about 120hp gain. So difference is only 20hp or so.
Which raises a legitimate question - why the hell should we suffer smell from catless DPs for just a mere 20hp difference (Stage 2 requires DPs)?

Another thing to consider is that all tuners give different numbers, some tuners Stage 1 is more than others Stage 2 - at least on numbers, which I think may be a BS. The things are more complicated because not many tuners properly disclose on exactly what dyno their charts are made. This is important as DynoDynamics is tougher dyno (shows less) than Mustang dyno - which in turn show less than Dynojet (btw most tuners use Dynojet in their graphs and sheets and results look a lot better than they are on let's say DynoDynamics dyno)

I can go on and on, but IMHO there should be a common denominator to all this tunes so that we can know what we are paying money for. $1300 to $1900 is not cheap. especially given that it's usually just a over the counter tunes that they sell in bulk and especially now that no more DME drilling is required - they can just sent us a file that we can upload via OBDII in under 10 min

IMHO amount of max boost in bar or psi should be one of the specs to look for in a tune - it gives you a some idea (not complete as other things are at play) of what a tune is capable of. For example I'm flashed with Stage 1 tune and I want to know if going with Stage 2 will be beneficial and I don't want to end up with less power - which is possible depending on tune.

Enough of my rant, but what I'm trying to say is that tuners need to be more open to public, they need to work with us if they want new clients and money. We need to be able to get all the answers - which we clearly did not in this thread. It's not VF-Engineering fault, almost all tuners on my experience are like that: they disappear when you asked a question. I understand they are busy, but this is the only way for them to get money - they have to understand it and work with us - otherwise people won't do it - there's too much troubles to begin with, very few will decide to have a tune on expensive car that costs $50k used

European tuners offer stage 1 for 500$ and stage 2 for 80$ extra . Also through OBD .
