Cobb Vs. JB4

SeanMc · 03-27-2013, 07:17 PM

I have an '07 e90 335i and of course the first thing I'm going it get a tune. However I have been stuck on this for a while, Cobb or JB4? I understand the benefits of both and was leaning towards the Cobb but i see more people with JB4's rather than Cobb tuned. Which would you choose and why? Please take into consideration price, ease of installation, and performance enhancements.

You have no idea what you just did.

Dozhdbog · 03-27-2013, 07:25 PM

This is going to be awesome.

Wait... have you thought of Dinan?

sathoro · 03-27-2013, 07:33 PM

When I get a tune I am going to get JB4 simply because it is cheaper, and you can switch maps while driving unlike COBB you have to reflash the tune which if I remember correctly takes at least a few minutes and you can't be driving the car.

Power gains seem to be the same and install for JB4 doesn't look hard but I would like to hear what the COBB guys have to say.

Love my Cobb

Cobb there is no comparision, I'm surprised people still by JBanything.

Its like a real women or one that dresses like one.

pHo_e92 · 03-27-2013, 08:28 PM

i vote for procede lol

Karbon · 03-27-2013, 09:11 PM

I personally like Cobb because it doesn't require anything to be attached to the car for it to function.

Install and uninstall easily.

E90Company · 03-27-2013, 09:17 PM

COBB, unless you want to buy my JB4 for sale

curious to read peoples comments

Carl64 · 03-27-2013, 09:57 PM

I've researched this a ton. If money is no object or you have warranty Cobb. Sure the JB4 is easy to uninstall in your garage but not if you're stuck on the side of the highway waiting for a tow truck to come take your car to BMW.

get both...twice the hp bro!

Not sure if this is sarcastic or not. But it's actually a good idea I am running the JB4 with the BMS flash via COBB can't complain one bit

Or you can call a tow-truck because your car died while flashing it with cobb. There are a lot of incidents of cars dying while flashing a map.

most people who want a tune dont really take advantage of what cobb can offer.

Jb4 offers more features (huge part of why JB4 is awesome), can offer similar or better numbers, and is almost half the price of a COBB.

Switching maps on the fly/ methanol and e85 capabilities/ gauge hi-jacking(boost/AFR)/ Auto-tuning/ hot & cold protection/ ETC.

Cobb can make the same amount of power, but would require some pro-tuning. Its also the "easiest" to install and the accessport is a cool device. I think jb4 is a better bang for your buck though. Your investment is also protected a little better also. cobbs keeps their price well.

I think his main point is, if you're stuck on the side of the road, you can just use Cobb and uninstall before the car gets taken into a dealership for repair. That way they can't blame the tune for your car failure. As opposed to JB4 where you need tools and probably don't have them with you in the car.

yeah i was just joking and what you said is very true.

but to install/uninstall a jb4, all you really need is a 8mm/13mm wrench and a flat head really.

liang · 03-27-2013, 11:26 PM

The warranty issue aside, I prefer JB4.

This topic has been covered so many times that no body should want to argue about it. Both tunes work great. Make your decision from price, install/uninstall time and features (maps etc).
