Flashed Bootmod3 map to my 50i

[menelaos]

He must have addressed that to me, yeah...dealers are killing us.

So is this tune untraceable by dealers? I removed the JB4 from my car cause it did nothing. Looking for something new but would hate to hurt warranty.

Thanks,

Greg

I am intrigued by your tune.
May reach out via PM for more details on the whole process.

Yea man. Reach out anytime. PM me when you're ready and i'll shoot you my phone #. Easier that way

Thanks....what scares me when it is updating and they ask you to have a battery charger for precaution!

Ok, just reverted it back to the stock tune. Total time was 8 minutes and that included turning the ignition off for 1 minute before starting instead of the 20 seconds it tells you to wait. Put the stage 1 tune back in 20 minutes later. I didn't time it but it took about the same amount of time. Voila!!!!

Importing the tune for the first time and then flashing takes the longest amount of time. I can't give you a good estimate because I was trying to import the tune while they were doing server maintenance last night, so it took awhile. Then I had some errors trying to flash. I was still seeing malfunctions on the dashboard after flashing, waiting 20 seconds and starting the car. I decided to flash again but I waited a full 5 minutes before starting the car and all the codes were gone. Everything worked itself out in the end. The support from the guys at bm3 is excellent. The guy I was emailing back and forth with the errors responded right away and was going to remote into my laptop while plugged into the OBDII but it didn't come to that.

I would probably recommend the battery charger for the initial import and flash. I didn't have the battery charger hooked up last night for the initial install but it's definitely a good idea if you run into some trouble and it takes longer than expected. I used the battery charger today tho. I wonder if it's more about keeping steady voltage while it's doing its thing.

Do you connect the battery tender to the negative pole under the hood and that's it?

I would also like to know? When I had my Cobb AP on my n54 it would leave no trace supposedly when flashing back to stock, but I would always wonder if the dealer can actually see how many times your Ecu had been flashed.

I connected to the positive and negative pole.

I'm not sure if any tune is actually "undetectable". If they're looking to deny you warranty, i'm sure they'll find it. I could be wrong

Does the $895 include the downloadable tune? Are there multiple different configurations/tunes to choose from? What is the claimed power gain?

Thx

Yes, it includes 1 OTS tune. 2 tunes available for the F15 50i. Stage 1 for stock vehicles and stage 2 for high flow midpipes. They told me it's 100 to 120 hp gain over stock. After driving the car for awhile... I don't doubt it.

Most of the current tunes (only two vendors I know of) sell their stage 1 for around $1200 and then I think you have to pay for their cable as well. They claim somewhere around +127hp over stock. I imagine this is somewhere close to those claims.

BM3 looks like it also has many of the same benefits as those tunes.

You do need to buy a cable for this as well. Around $20 from amazon.

Seems a bit high, I would believe it by seeing dyno before and after numbers, just think that’s a little on the high side for just a flash no other mods. That’s would be like 80-90 whp increase.

Is this the same cable we use for coding?

Additionally, are tunes (stock and stage 1) downloadable to your local computer or are they only available through the cloud?

Not really. I got a 70 hp gain with just a tune on a supercharged mustang and about the same on my CTS- V. Both with no other mods. So being that this is a twin turbo vehicle... 100 hp doesn't seem far fetched.

I haven't done any coding yet so I'm not sure about the cable.

Tunes are stage 1 and stage 2. See my earlier post in this thread.

I saw your earlier post, but what I was wondering is if you download and store the tune locally on your computer or do you have to have an internet connection and stream the tune while you are flashing?

Do you know how much higher the boost is then stock? Even if you were gaining 20-25 hp/ per lb of boost that’s a 4-5 psi increase sounds pretty high for not having any other mods to help out. But if it is then that’s great bang for your buck. I’m very familiar with turbo vehicles and what tunes and boost increase can do, I have owned n54 , GMC Syclone (for some older people that know what this is) and currently still have my evo8 running 30+ psi ( built 2.3 / fbo)

Unscientifically, I measured my baseline at like 16.3 lbs with Torque Pro and then again with the Racechip (when I had it at the time). With Racechip on C setting or something it would read around 19.7+ lbs of boost. People had dynoed before and after going from 391awhp to 450 or so. So the marketing numbers of +100hp seem to be fairly accurate when you take into account our 15-17% drivetrain loss. That would be 60awhp increase from the piggy for only 3.5lbs additional boost putting it into that neighborhood of 25awhp per lb boost increase.

I would have to imagine these tunes (BPC went up 127hp on n63tu) are fairly comparable to each other and will be higher than the RC. My stage 1 tune on my 335i would dyno 350 or so over the 288rwhp it had stock with no other mods. I think it can handle a 60-70awhp increase just fine with out anything else.

I read somewhere that stock 50i boost was 16psi. I imagine these tunes are taking that to around 20lbs targeted.

I am debating on splurging on this soon after i get my plugs replaced which are misfiring. Then I can run the same analysis and see what it shows. It is about half as much as the other market tunes.

Very valid points, I too netted 70 awhp from ots stage 1 / agg 93 oct Cobb on my 335xi, went from 260 to 330 awhp. Yeah I would agree 100 to crank but not the wheels, for some strange reason I was thinking 100 wheel hp gain and I was like. I actually want a tune for my x5 and I’m still on the fence about a piggy or flash tune but my car is cpo so still need the reverse it when going to dealer and need assurance that flashing is undectable if something where to go wrong.

I didn't get CPO on the 50i but I had my tune on my 335i and would flash back when going to the dealer. I never had any issues. My warranty is up in June. I debate on 3rd party but am not really worried about it all at this point. One of the tuners says they defeat the flash counter if that's is of interest to you.
