I have a 435 with a JB+ and an ER charge-pipe. I would like to get a better tune. I planned on getting a JB4, but a lot of people seem to be going with a flash tune these days. My car is not tracked, I'm not hard on it and the only other thing I plan on doing to it is a bigger intercooler. What are the main differences or pros/cons between the AA Simon3, Bootmod3 and the MHD flash tunes? Also, what were some of the deciding factors that made you choose the tune you did? Thanks

Are you going to mod further? Like downpipes / FMIC etc.?

Just an fmic, no down pipes or bigger turbo. Not going fbo.

I'm in the same predicament. Currently the only MODS I have on my car are a drop-in filter and MPE axle back exhaust. Definitely doing an FMIC and intake but don't really want to mess with downpipes or other MODS.

Have you looked at the BMS Stage1?

Jb4 is also a great option.. With JB4 if you get more mods it will grow with you and if you ever go full out you can always loud their FREE back end flash, so you will have JB4 and flash together but that would be only for FBO+

Look at the BMS Stage1..

Perfect fit for your plans I think in terms of power and its VERY budget friendly

Being that I have a JB+ now, would there be enough of a difference in power between the two where its worth getting the Stage 1?

started with hondata for my acura back in the day and recently my N20 DME flashed a few years ago. if done right, flashes are better because it is not tricking the DME but an actual reprogram/remapping. most flashes can be tailored to the mods you have and they tend to have smoother power delivery than a piggy back.

although i do not have any knowledge about it, except for what i've read here, i would do the simon3 active autowerke obd2 flash. street tune, tailored for minor bolt-ons.

MHD flash is the way to go. Ongoing development like bootmod3 but cheaper.

Yea, I've read that to about the power delivery of a flash tune. The jb comes on more abruptly where as a flash's is more linear. I wish the decision was easier, but it's between 4 tunes.

I don't mean to start a MHD vs. Bm3 war thread but I'm just waiting to see differences between these 2. Features, support, etc. to make a decision (I'm FBO right now)


Per my experience, Jb4 can cause some jerkiness here and there but nothing that I can' get use to.

Even though you don't plan to do any major mods to the car and you are planning to go conservative/comfort. I recommend getting a flash anyways, you can get your car tuned, improving the driving experience in a smooth OEM+ feel.

Definitely go with MHD. You can't beat the price it's much smoother than JB4. The only reason I'm stacking JB4 + BEF is because I've had a JB4 for 2.5 years now and like the safety features + smoother delivery of the combo. If I was just getting into the game MHD is the best value by far.

So you are currently running jb4 with a bef? Which bef are you running, ots or custom?

Can you provide some insight on how the car changed after adding the bef? Very interested in hearing a true comparison between jb4 and jb4 + bef as this is the route I will be going this spring.

Thanks!

I don't want to hijack the thread, but I can give my quick two cents. I have only had the combo for a few weeks now, and the current BEF from Burger Motorsports is still in beta testing. Right now it feels a little smoother and makes really good power (Was seeing around 16psi average in my logs). Terry is the man, and a great guy to work with. He responds almost instantaneously when I email about issues/questions. Right now it's pretty feature-less, but I have heard from him that he is working on a lot of revisions and features to be tested soon. So it will definitely get better with time, and having all of the safety features from the JB4 + increased control from the BEF really is the best of both worlds.

While I won't presume to tell you what you should do, I will relate my experience. I had the MMPK software with the Dinan Sport in Sport+ mode. While it made good power I felt driveability suffered. Under less that full throttle it just wasn't as smooth as I'd like.

I just finished installing the AA tune this afternoon (thanks to raichean for the assist). I am more than pleased with the result. The car is as smooth as stock and feels at least as powerful as the Dinan Sport likely considerably more so. I've only driven it for about 20 miles or so, just enough to get the oil up to temp. Part throttle response is outstanding. I chose AA for a number of reasons.

1. A long history of BMW experience.
2. Exceptional customer service. Pre-sale email questions were readily answered, often within minutes.
3. They use your individual car's tune to create your new tune. Others may do the same, I don't know.
4. The ability to copy and reapply any coding you might have done through their software.
5. The added comfort of purchasing the product from Mike at Extreme Powerhouse. In my opinion one of the most responsive and reputable vendors here.
6. And finally, I'm an old PC guy. I have a couple of android devices but I'm not a big app user. I'm much more comfortable using a PC based tool.

As I said, I'm not telling anyone what they should do. I'm sure the competing products are excellent and the vendors offering them are first rate as well.

Thanks Mike. I looked at it and I'd rather go with a flash tune to be honest. I'm not a big fan of piggybacks.

RK tunes in on long island..did some research and liked what i saw.

Here is the single biggest reason to flash:

You actually tell the computer what you want, instead of tricking it.
Look at these two data logs. The throttle closures at WOT is insane with JB4. It is not smooth what so ever.

The bottom log is a flash tune.

I can physically feel the throttle closures in my car with jb4, actually feels like the car is holding itself back I had no idea what the deal was u til I studied the logs and did some research.

Car really doesn't feel all that smooth at light/partial throttle either (I thought so stock and noticed it more so with jb4 almost lugging sensation sometimes). That is my biggest thing to fix with bef is smoothness under partial throttle.

Tchao That is awesome.
