One of my fav. features of Proceed/JB4 is ability to switch maps on the fly when extra power is needed and remain un-noticed once removed.

imo, switching maps for this reason is kind of silly. Keep your foot out of it and you won't put any more stress on the engine than running the stock tune.

After the initial install of the access port, switching maps takes about 2 minutes.

As to why some like cobb more than jb4, it is an actual tune. Where as jb4 is a piggyback and basically tricks the ecu into doing what it what it needs. this is not to say that the jb4 isn't good, cause it is. This platform is a little unique in that the dme is so good at protecting things a piggy-back solution works well.

Where as, if you look at most any other platform piggybacks are usually there in the beginning, but go the way of the dodo bird once the ecu is cracked and flash tunes are available.

Flash tunes are out there but haven't quite caught up to piggybacks. Dinan, for instance, costs about $2,200 and only nets 400hp. The JB4 will do that and save you around $1720. Also flash tunes can be deleted on accident and to re install a Dinan tune you have to pay for the hour worth of labor.

Mine was re-flashed free last year when another dealer job blew it out.

When I had a Dinan tune they told me that if a dealer deleted it all I had to do was pay the labor charge...greedy fawks.

Awww man- freakin bastards..
Sucks that they can't follow a standard

Jb4 And Cobb!

[kevinbahnz]

Cobb, because I'm Lazy

Thanks for everyone's input, just trying to understand why the JB4 even if I've already seen the stat sheet. The stat sheet explains the features, rather hear the facts of what people have experienced then reading the manual

Great explanation.

Cobb is easier, but jb4 and procede aren't hard per say. The Cobb is ultimately a "better" tune strictly speaking especially for very high power (on paper mostly though, in the real world it's all very close), but the jb4 makes everything easy mode. For your goal of 380whp both would be completely capable, so it comes down to ease of install vs added features and $$ for your application imo.

I have a JB4 with FBO and it makes great power. Now that i am playing with E85 in the 40%-50% i am going to be adding the BMS flash with the Cobb. Both Tunes are great but it is truly up to you. Right now the JB4ISO w/FBO, stock Turbo COBB and E85 mix has the fastest N54 1/4 time at 11.2

Bottom line is, you can't go wrong with any of the tunes available for this car.

This needs to be updated there's one more tune out there.

Jb4 , Procede, and Cobb all have their benefits to people.

Let me preface by saying this is just what I've noticed on here by my customers:

On your basic otherwise stock vehicle some people simply prefer JB4 because of it's price point. Others may choose Cobb because it's easier to install and they like they idea of a flash tune VS a piggyback.

There are also a bunch of the reasons inbetween people choose one tune over another have it be brand loyalty, customer service support, or maybe a friend recommended one over the other.

Some like PRocede because of their integration with methanol, others can say the same for JB4 too. On the fly map switching, auto-tuning, ETC ETC are some other factors. E85 is also a new trend and I still believe its in it's infancy as all the tuners work out their bugs and find more fueling capacity.

Some people swear by flash tunes. Others don't care and if they can get similar power cheaper then that's their style.

The important the thing for the end user to decide is what they need out of the tune, learn the benefits and possibly cons of each tune, and deduce what is more important for them.

I can get into a bit more specifics but that always ends in a tuner war. There is not necessarily a wrong tune to get, but, if you have certain demands or things you want to avoid from a tune let us know and maybe someone can steer you one way or the other. Keep in mind there are many misconceptions, and biases. Everyone wants to believe they have the best tune so they usually just recommend what they have. (no offense to anyone here).

If you want the most unbiased opinion I can offer, shoot me a message and tell me what your looking for out of your vehicle. I can help.

Power Goals
Type of Fuel
Modifications
Turbo Upgrades
Methanol
E85
Installation procedures
Customer Support / Tuning Support

Those are some reasons to choose one tune over the other.

Nicely said and I shall.. I'm use to the Evo scene so we use ECUFlash so it's a bit different

Half the price, more features, more documentation, programmable via steering wheel, better support, new features always being added, etc, etc. Nothing actually wrong with a Procede IMO. But it just doesn't have the same value. You really have to ask yourself if you see the value in the same way.

In defense to PROcede many features JB4 has have stemmed for PROcede. As someone like myself who has been following the platform for over 4 years there is a lot of history between Vishnu and BMS (way before Cobb was even around).

The strongest aspect of the JB4 is it's price point and HP/Dollar.

[M3coupe]

Having had both the proceed and the JB4 that hands-down winner is JB four if not only for the rockstar support, even though there are more reasons. Best I've ever seen

I also wanted to clear up a big misconceptions since it seems to be popular lately.

Map Switching:

The purpose of map switching is not to change maps from "stock" to "tuned" between driving aggressively and driving to work.

The purpose of map switching is to change maps if you so in fact add different modifications or octane you would have the ability to simple change maps right their on the fly. This is different from your traditional flash tunes as you would need to re-upload an entirely new map.

IE. If you were to add race gas to your setup, you can change to a different map on the fly to take advantage of the high octane until your next fill up of regular pump gas.

If you intend on daily driving you leave your car on a tuned map. Your car will drive the same around town, and on the highway. It won't put any additional stress on the car. There is no point to change back to stock map.

Daily driving on a tuned map is no different, you just have more power on tap if you decide to put your foot heavier on the gas. Driving on the highway and cruising in town or traffic will be no different then a stock map anyway.

In fact I would advise against switching it as that leaves the car constantly fighting itself to re-adapt and relearn driving habits. (Yes there is somewhat of a learning process when your car goes from a maximum of 8 or 9 PSI to 15-16 PSI. There is an increase of heat, EGT, timing and fuel changes that need to be re-learned.

That brings me to my next subject later... Auto-tune Misconceptions. I'll hit on that later perhaps.
