    I'd think it would help fill all cylinders equally, especially under boost when the air is more dense, and even more during higher engine speeds when the air is both dense and turbulent in the plenum. But, I could be wrong.

    I'd love to hear your reasoning on why IDP's serve more of a point when boosted than when NA.

    Short answer is no. Cylinders need tb opened at different point in rotation.

    Yeah was just a joke. You can see the fire hose he has on your site. Always great to see new features.

    I don't see why you couldn't drive all TB's off a common shaft, maybe with a pushrod system, and place the stock TB motor on the end of the shaft. There would probably be some tweaking required in the DME to retain stock-like drivability, especially at light throttle and off-idle. Cool project, but like the others, seems like an incredibly expensive project for the minimal gains.

    I see, is it common to do the same on S54 turbo builds?

    There is a point, actually more of a point than there is in N/A motors. Your understanding is incorrect. Although it works the same in principle (More air), you act as if boost is free. It isn't. Increasing boost has many negative side affects, it costs power to increase boost, it raises IAT's, it puts more pressure on your turbo and charge pipes, creates more heat, and doesn't help off-boost performance. CFM > PSI. If we can increase CFM without increasing PSI, that's the ultimate goal. But now you're slower, and use more gas. I like the M3, don't get me wrong. But a FBO N54 embarrasses the M3 in everything motor related. Care to explain why? And what advantage does twin throttle bodies have?

    Helping customer via email so I don't know what their forum name is. The spray pattern is probably horrible due to the large nozzle size and meth bungs that are too tall. I suggested he go to 180 degree apart CM10s to evaluate.

    There are a host of other changes we're playing with but since fueling related safety systems have become a discussion point recently I figured i'd share the details on it. I think we also found a way to "reduce" the port injection backfires during manual trans shifts. Waiting for some customer feedback on that though.

    Exactly. Since the JB4 reads that data real time in the background it's always active regardless of whether or not the interface is selected to display the bank2 trims or not.

    Competition is great, isn't it? BMS basically owns the BMW piggyback market. Dinan has tried to muscle their way in (despite saying piggybacks are bad) as their flash tuning business is basically gone with the new Tricore ECU's. It has not exactly gone well for Dinan as their piggyback products are overpriced and they underperform. Well, overpriced until they launched a basic boost controller for N20/N26 and N55 engines retailing for $299. That conveniently and deliberately undercut BMS and their Stage 1 tuners which start at $379. BMS is responding with a JB+ F-Series option that starts at $199. BMS states the JB+ will provide ~35 wheel horsepower. We do not yet have a dyno confirming this but it is on the way. Suffice it to say BMS historically backs up their claims with dyno graphs. Dinan on the other hand does not. It sure would be fun to do a back to back test of these two on the same car with the same fuel on the same dyno. Maybe it's something BimmerBoost can make happen. Either way, BMS continues to offer the best performance gains per dollar in the BMW aftermarket.

    Think further outside the box and eliminate the TB completely with GDCI http://delphi.com/docs/default-source/2015-sae-technical-papers/gdci-multi-cylinder-engine-for-high-fuel-efficiency-and-low-emissions.pdf?sfvrsn=4

    I thank you for the new safety that's free! Is there going to be any other new toys in the next update? This safety might make me put my meth kit back on.
