jb+ only and 3 ppl in the car did 12.21

I think it's super helpful that you posted this. I'm also not defending BM3 at all here, but we also have to remember that the purpose of Software Base Flashes, aside from maximizing performance, is also doing it safely to the point that it isn't going to destroy the turbo or the car.

JB+ has the capability of pushing the PSI +4.5lbs over stock if you really wanted to go for it, and while I'm sure you can get great numbers from it, at what cost? Like you said, this is in its current state. I'm sure as the maps get more defined we'll start to see some amazing numbers.

The ironic thing is that the DME in our cars are quite sophisticated and will pull timing as well as throttle when there is knock from too much heat or add or pull fuel in rich and lean conditions to protect the engine. In a vacuum that means the JB+ is quite simple and safe. I've used it on my M40i and it worked completely fine despite what anyone says. Great midrange and about the same top end. For most people, that might just be enough for the price. Although stock MPPSK tunes run egregiously lean from the factory.

Full DME tuning is a much more precise business and in some cases you can even lose power when asking for too much. It is strange to me that everyone getting these tunes simply say.."Oh I'll just wait for updates for it to be faster" Didn't these tunes go through dyno tuning & beta testing? If that's the case, shoudn't they work great out of the box? I digress.

One thing I will say, from tuning all my cars for over 20 years, including for extreme race track conditions, is that the Log posted earlier in this thread is pretty much consistent with these real world results on this draggy test. it is on par, more or less, with an MPPSK tune if you're on "91". I'm guessing more octane will get more power but with that said, for the price & features, it is a much a better deal than the mppsk with better AFRs & minus the exhaust. Of course, take that for what you will if you were expecting a much more power over a mppsk car on 91.

So what's the deal here? PTF's Dyno isn't accurate? JB+ is underrated? Am I better off with my JB4?

its certainly been an interesting couple days with info all over the place from all the posts, im a little confused myself

You guys have to keep in mind it's on 91 map that has to accommodate all the regions with piss poor quality. I'll have the tests with 93 map out as soon as we do them and I'm sure it'll do much better than jb+ in terms of numbers. Not to mention the engine is much happier with the flash rather than jb+

okay makes sense sorry new here was 91 in the tank or is this a 91 map or both. I'm trying to get if this was apples to apples comparison same car same fuel just the jb+ and then the BM3. It seems there has to be a difference, ive not seen great things about jb+ especially on 91

Exactly right..I'm sure it's as smooth as butter & consistent comparatively to the JB+.

[EricVR4]

I flashed to Stage 1 93 a little bit ago but am having an issue with the exhaust valves being open no matter what drive mode I'm in. I've tried adjusting the configuration but it doesn't seem to matter. I have cold start turned off so the car starts quiet but then the valves open after 20 seconds or so. Am I missing something obvious? No warnings or malfunctions either, the flash completes 100% each time without any issues.

I have MPPSK so it's fairly loud and I like the option of Comfort mode with the valves closed sometimes.

Yeah it definitely is. Car is much more responsive compared to jb4 low down, whereas the jb+/jb4 had nothing low down and then a surge of power

Same here! I would love input on this subject. I'm all for the beautiful exhaust notes, but some times I just want to cruise on by in stealth.

Also interested in having this confirmed/sorted out. Agree with both of you- have MPPSK but prefer knowing I have the option to silence when pulling into work in the am

On a related note, for those that have MPPSK and access to 93, what is the verdict so far on the drivability and power increase with Bootmod3?

I have JB4, but it's wildly inconsistent - excellent today, but varies from day to day

[EricVR4]

I went and drove it again and it's throttle related. I have cold start delete turned on and it's nice and quiet on start-up but the second the throttle gets touched, the valves open. The burble/over-run isn't there while in Comfort, but the valves are open. Once it's in Sport/Sport+ then the over-run comes back. I think it might have something to do with the throttle maps being modified too, like a couple other people have noticed earlier. The throttle doesn't feel like the regular Comfort setting so maybe the MPPSK exhaust/valve gets confused by that change? I'm curious to hear from PTF about it.

As for MPPSK/93, I haven't had a chance to get on the car much (I live in the city in Houston) but the powerband is definitely a whole lot smoother than the MPPSK tune. A lot more torque down low too from what I can tell so far. I'm definitely a fan of the Stage 1 93

I envy you. California laws and emissions OP, stuck on 91 here. Plus I'm in Bay Area so don't have luxury of easily sourcing E85 blend.

so me too, about 8 months out of the year in ca getting 91 im trying to understand based on what ive seen here posted earlier if the tune on 91 is worth it vs the jb+ that the other poster mentioned. like i said based on what ive seen the jb+ doesnt seem like a comparable offering vs the bm3 but i don't know now due to the draggy results i cant get 93 or e85 most of the time

[ScubaJ813]

Another question...

For stage 2, do I need to to gap the stock spark plugs? I just saw on an MP thread, on their s1.5 and s2 it's basically required.

My opinion. Tuned. It's just the safer more efficient route. Sure piggyback might have higher numbers, but at the end of the day from my understanding it's manipulating the dme to attain the results you're seeing. Plus it's only the beginning phase for b58 on bm3, once the market expands you'll see the kinda options and numbers n54/n55 has

[B58togo]

^^

Seeing N55 numbers would be a huge step backward.

[Cookie933]

What are the most safest aggressive settings for burble to use with a completly Stock exhaust system?

You're right. I was thinking in terms of a heavily modified n55. Apples to oranges, but was hoping to compare the support and options we'd get as adoption of b58 increases

[HitmanHearns]

For us stuck with 91 in southern Cali, if anybody lives in San Diego, there is a gas station that has 95.5 octane (also 100 octane). Can’t remeber the price of the 95.5 octane.

Not familiar with any 93 or 95 in Los Angeles though.
