JB4/Cobb App FMIC NEEDED?

so i tried searching on here but couldnt really find a yes or no answer.
So im still deciding on either the JB4 or Cobb App tune but the question I have is, do I need an upgraded FMIC if i use either of these tunes or will the stock one be ok.. I eventually wanna upgrade the stock one but im not sure if I need to do it right away or can it wait a while.

The chart at the bottom of this page will tell you what you'll need for each Cobb standard map... http://www.cobbtuning.com/BMW-N54-Ac...maps/bmw/IKB0S

You might not have the IKB0S ROM (ECU firmware), but the chart will apply anyway.

And I thought you were going with JB4, or am I mixing up threads? :-/

I don"t think a FMIC is something you have to do right away but I would suggest you do one if you plan on owning the car a long time. If your leasing I probably wouldn't do one at all. I have Jb4 dp's and cai and I have ordered a FMIC because I own my car and will keep it for a long time. I am not doing a FMIC because I believe it will give me some sort of crazy hp gain I just believe its better for my turbo life. One thing about these cars they run at higher temps and when you do these tunes your drastically increasing the boost over the factory levels. With all the turbo cars I have dealt with in the past i have seen heat and high boost lead to expensive repairs. I have always upgraded the FMIC and added a turbo timer to all my cars and I have not had a major issue yet (knock on wood). Understanding how to care for and maintain these cars once you start doing these high performance mods is very important.

You can run without it on the lower maps of either tune with no problem. If you move up in power its a good plan to get one. Problem is its very easy to move up even without a lot of hardware. 335IS are running in the range of 390/400whp with the newest IS & 1M specific maps using a 40% mix of E85 into 93 octane with just a tune.

I was going to get the JB4 but i called a local shop asking if they sell it and said they dont sell anything that isnt CARB legal in cali. That then made me rethink of purchasing the JB4 because im not sure if it is CARB legal and i would hate to have to hassle with taking it off and on when smoggin my car, so ive decided to go the Cobb App route cause i can just reflash it back to normal. I plan on getting the FMIC within a couple of months after.

JB4 has pass-through mode [stock map] at the touch of a steering wheel button.

With laptop can also render unavailable by steering wheel buttons, useful for BMW service. Simply re-activate after service....USB cable used for that.

thanks..good to know that..think im gonna stick with the Cobb app though because I like the fact that they have updated/downloadable new maps and tunes that work really well with FMIC's. I dont mind spending the extra $$$ for a great product thats that much easier to use and still gives excellent results..

Both tunes work great and it really comes down to what you're looking for. The Cobb is a great choice. It's very user friendly and the installation and installation process is painless. You'll be able to uninstall the tune before you go in for smog or for any dealer visits. Software and map updates are also free through the Cobb AcessPORT manager.

Install:


Uninstall:


You will be able to run the various maps that are available depending on the mods you have on your car.

Map requirements:

Stage 1:
Intake any
Intercooler any
Downpipe any
Cat back exhaust - any

Stage 1+:
Intake any
Intercooler required
Downpipe any
Cat back exhaust - any

Stage 2:
Intake suggested
Intercooler any
Downpipe required
Cat back exhaust - suggested

Stage 2+:
Intake required
Intercooler required
Downpipe required
Cat back exhaust - suggested

The requirements above will give you a nice progression list of mods that will allow you to achieve full bolt on "FBO" status. Getting a FMIC will definitely help in keeping air intake temperatures down. I'd highly recommending it if you're looking to achieve more power later down the road.

I'm a huge fan of Cobb and have had it on two other car makes. You can't go wrong with it.

You probably know this already, but just in case you might want to change your spark plugs if that hasn't been done recently. Tunes on these cars require more frequent plug changes (25k miles) than normal, otherwise you may experience misfires and other issues.
