Has Anyone Gone From Jb4 To Cobb??

Hey guys I have been hearing alot about the new cobb about how wicked fast there cars have become..I like my jb4,but I heard that the cobb is a much better tune..I have so far as mods, the jb4 and the dci's but I would love to try the cobb accces port!!

Can I leave my jb4 on map 0(STOCK MAP)and flash the car with the cobb to see what I like better?.I also plan on doing catless d.ps maybe sometime next week.Will the map 2 with my d.p's make much more power?Has anyone dumped the jb4 for the cobb,and if so are you more happy now??thanks.

Look at this comparison / thread:

http://www.e90post.com/forums/showthread.php?t=374508

JB4 has the most N54 cars in the 11second range. Cobb is not faster than a JB4. It may be more convenient yes because you use a hand held flash tuner but that is it.

Also Cobb hasn't even come out with anything for the N55 so it shows how far behind they truly are.

future Cobb OTS/ATR maps will easily put the Cobb tuned cars up there... as for being far behind, it hasn't even been a year since they've been out and they've already made a huge impact... compare their tune to the original JB/Procede a year into the product line.

Also, that link is pretty useless for comparing the Cobb AP to anything.

Lots of information of these boards, alot of misinformation as well, do your research, search through some threads, etc. Alot of former JB4 users with Cobb now, not sure how many have gone the other way.

It really just boils down to what is best for you and your budget, One is a piggy back and one is a flash. Both have their advantages.

I went with a Cobb AP and love it. Backs ur current stock map and installs in 20 minutes and uninstalls in 10. The price for the unit is around $800. Jb4 is around $450.

The Jb4 has proven to be quicker than the Cobb but the Cobb installs / un installs very quickly and has a lot of potential with the updates.

Cobb doesn't have any support yet put for the n55 and are still developing their stage 2 for the n54. Hopefully once the stage two drops we can do another comparison.

Either tune will transform your car and you will be satisfied with either. Suspension mods should be next on your list.

When you're the first to innovate something (JB/Procede) of course it takes longer to advance it. Can't compare someone(Cobb) coming into the market and already being able to reverse engineer the competition and use it to their advantage.

I am just saying, look at the N55 market. Cobb hasn't even released anything for it while JB / Procede have been pioneering it. Now finally flash tunes are coming out into the light.

Only reason I would consider Cobb is if you don't have the mechanical skills to plug / unplug the JB / Procede. Since Cobb is easier to use yes.

Not to mention Cobb is taking the time to do it right and do it right. It takes a substantial amount more time to crack the dme's programming than it does to throw a signal modifier on a few sensors to make some power. Programming is far smoother from a drivability stand point as well. I've driven cars with just about every type of software or piggyback in them. Dinan and Cobb tunes are far smoother than the procede, jb4 or ap2. Maybe not as quick, but just as smooth as stock with more power. once the tunes are out from Cobb, who keep in mind got into the game way later, they will have the markets best tuner. Don't think so? Ask Shiv what happened to the proceed/excede sales when Cobb got the suby's handled... Vishnu had to bow out! His product for the N54 does have some cool features, but he also has a head start on the cars of several years. also guys, just because nothing is released, doesn't mean Cobb doesn't have anything ready. Believe me, they do a lot of real world testing before dumping it out into the public...

Bottom line, think what's better for you as an individual. Ease of installation, proper software, cost, etc. You may not be a drag racer, so is squeezing the last few HP out of your engine necessary? BMW's aren't made for drag strips any way....just my .02

I went with JB4 because I like the user adjustability. If one weekend I want to run race gas and take advantage of it, I can easily switch maps for it and benefit from the higher octane. Can't really do that with the Cobb as of now. Cobbs stage 2 does look rather promising, but I'll have to wait and see how it does and also see if they address their throttle closures.

Since this is essentially a flash tune compared to a piggy back question, I don't see how that's a relevant comment. I don't think Cobb reverse engineered anything from JB/procede... you could maybe argue that for GIAC.

A flash tune still adjusts similar types of parameters that a piggy back does to create power. Makes your job alot easier if someone has already changed those parameters and decided what works.

Only thing they would need to do themselves is the OBD flashing, which I haven't been around long enough for the N54 platform to know who the first OBD flashing tuner was.

the jb4 hardly just "throws a few signal modifiers" onto the signals. burger and Vishnu were the first to crack the dme and though I'm not saying Cobb didn't do a great job or anything, the two big piggyback tuners coming out with tunes and working so fast to crack the ecu shows dedication. Cobb is great but at this point jb4 simply makes more power and while its harder to install at this point I can install it in the 20 minutes I'd be sitting there waiting for the software to upload anyway

This post is complete madness.

Reverse engineering the ECU, communication protocols, flash algorithms, disassembling it to see how it works, finding the look up tables for everything, figuring out how they interact, when they're active, etc. is a much harder job than adjusting fueling, timing, wastegate, and boost settings. WAY harder.

Tuning a car is an order of magnitude easier than hacking an ECU.

FYI...I have an Engineering degree and Computer Science degree and can take apart almost anything. This is not rocket science. I chose Cobb A/P due to the efficient use of the OBD and flashing plus future upgrades.

the whole flash being smoother than piggy argument is a joke... Maybe back in the original days of the JB and Procede that was true, but not any more. Im not saying piggyback is better it is just more versatile. Unfortunately that versatility comes with a much more involved installation/deinstallation. It is all a matter of preference. Do you want to have to get your hands dirty for a few more features or not?

Oh and the COBB is by no means faster than either of the piggys

Would you rather have a proactive system or a reactive system? I'll take proactive, being the built in tune. If the procede is so good, what happened to them when Cobb released user tune-ability for the subys? Oh, end game for Vishnu....it's just a matter of time...

Maybe Cobb should test their stuff before opening Beta maps to the public.
