Here are a couple random customer who provided logs from the 1/24 maps, both using the BMS methanol kit and open intakes.

The first is default map 7 doing a 1/4 mile run, and you can see how boost is tapering to only ~11psi at the shifts. The customer VBOXed the run and hit 120mph+! Simply amazing for these mild boost levels.

The second is from a different customer who is at a higher altitude, and was captured on map 7 with top end boost taper reduced to around 14psi at redline. It's a long 3rd gear run. Holding this kind of boost at high RPM is not particularly safe, but with the JB3 you have the flexability to set taper as high or as low as you want.

Cool stuff

17psi at peak power on map 7....bmw is going to make some money on turbo warranty work this year.

That is the beauty of user adjustment, you can hold as much or as little boost as you want. But I'm with you, don't expect turbo hardware to last long under extreme boost levels. It's just common sense.

Default on map 7 is around 15.5psi peak taper to 11psi @ sea level per the first log.

Now that JB platform is able to datalog, they should really clean up the graphs and spend more money on the software since they are going the same route as their competitor and they should make it more user friendly to read...For new users, looking at the logs, it looks like a child with a crayon thats gone wild!

and up that sampling rate!

Wasn't it noted in a thread that 380hp was a safe limit?

I'd be ecstatic to have hard evidence to support what actual psi level is detrimental to the turbos/engine and what horsepower level, as well.

I have been working on my car for the last year on purely cosmetic items. This year the warranty is up and I have been planning on what products to purchase in one big swoop. However, I still don't feel comfortable with 400+ horsepower levels without knowing longevity.

It's a mechanical device. There's no safe limit for one concerned with reasonable improvements and longevity. Everytime the turbos hit max stock boost they get a little closer to dying, if they hit max boost which is a little bit above stock they'd get closer to dying by just that much extra. If you're not dealing with actually coming up with enough power to snap the drive shaft or whatever then you're just lessening the time til something breaks from wear and tear. I think..

400 rwhp is not an issue on a full bolt on car. The turbos have been the concern, but with widespread acceptance of things like methanol you can get more power out of your car without less stress. I am sure the future will hold more of this as well.

The JB3 interface and logging is simply awesome and very easy to use. Nothing to configure at all. Just press start, do a bunch of runs, press stop, and it displays. Then you can zoom in and out, export to JPG, export to CSV to email to BMS, etc. Having all the data elements in one chart does wonders for analysis. To be honest I've used the V3 interface and I found it cumbersome and difficult to use where as the JB3 interface is intuitive and simple. Just this guys opinion.

Another cool thing about the JB3 is how it loads maps. Each set of maps/firmware is in one file, and you always load that file so they can never be mixed up. And while loading it doesn't trigger any codes...

More samples are planned, but here is a V3 log with 20?/samples/second and similar scaling. Is this really more informative or readable? I really don't think so. I don't need to see sensor noise, I just want to know what boost is. A mechanical gauge probably only gives 2-3 samples/second and is regarded as a great way to monitor boost.

ok....So Mike what would you consider setting the jb3 to boost and taper off at on a full bolt on car>

[Sniz]

Mike did you really just say a mechanical gauge gives 2 to 3 samples per second? lol

I would stick with all the tried and true default settings.

thats what i was thinking, the way i look at it is why mess with something thats not broken i mean dont get me wrong data logging is awesome for certain people but i know for a fact iam not going to mess with the P>S>I on my car that just seems to much for me.
