[oma3710]

So I received my jb4 and tried installing. The install seemed pretty straight forward. I go to turn car on and it turns on but sputtering. Help!!!

Recheck all your connections. The connectors can go on backwards if you are not paying attention.

I stayed w/ my Stage 1 until I could afford to buy a FMIC + DPs at the same time. That way I was able to enjoy the performance gains of the DPs while adding an FMIC, lowering my IATs + running that car at a more "optimal" setting.

In addition to the DPs + FMIC, you might also want to consider upgrading your CP + DVs. The OEM ones are made of plastic and some people have broken/cracked them when running higher boost. The most popular is the ER CP & from there people go with their preference of a DV setup (Forge) or a BOV setup (HKS, Tial, Synapse).

Just email BMS support with some install photos. Normally its a backwards connector or believe it not customers often forget to connect the JB4 to the harness.

Now getting U0100 "lost of communication with engine control module/powertrain control module A... Help guys. I have to work tomorrow morning.

[TotalBlackout]

Show us what you have done. If you can't figure it out put it back to original condition.

[Djg21]

Paid my audio installer $75 to do the jb4 and DCI. I helped but he had tools that made it really quick. It was not a difficult task.

[oma3710]

Got it done this morning. Im not even going to say what it was but just glad thats its working. I want to thank Terry from Burger. The best customer support.

[MrRetep]

Forget to plug in the power?

Im running map 1 but from reading today. They say that map 5 is better and stronger.

Some personal opinions please.

I told my buddy that my 335i is a beast after installing jb4. He wants to bet me $100 that I cant take his 08 350z. He only has an exhaust.

You will destroy him.

Edit: if you really want to hurt his feelings run the E85/93 octane map. You would put Amtrak train lengths on him.

With a tune? He will be trying to stick with you. Those cars are not that fast straight line.

I ran Map 1 for about 3 months, felt it was strong and did fairly well. Last week I updated my JB4 to the new 6/10 Alpha firmware, put it on Map 5 went for a few WOT for it to adapt..and was extremely impressed with how much better the car felt. Seemed like a more linear power band also hitting slightly higher boost than map 1. (my car is stock other than tune)

I definitely recommend trying out map 5.

Also, that 350z will get destroyed no questions asked. I ran a G35 (exhaust only) and put about 3-4 car lengths on him. (with map 5)

[Pete Schweaty]

Map 5. It will take a little while for the car to adapt, so dont do it right before you meet up with your buddy. My in dash boost gauge shows about 14-15 psi with only DCI on map 5 with 93 octane.

[oma3710]

Well during lunch today we hit the highway. I beat him by four cars on map5. Now he wants me to race his brothers evo to get his $100 back. What do you guys think? I know he has an exhaust, intake and boost controller. Can I make another $100?

[racerg35335]

You should be outrunning a 350z with a bone stock 335I. I used to own a g35 and it did not have near the power as my 335. As far as the Evo goes.... ya never know with those cars. They can be complete monsters. I would be careful with that bet!!!

[MrRetep]

Glad to hear you took the 350z

I would be careful with that Evo though, they can be surprisingly quick. Your best bet is from a roll, from a dig we have very slim chances. evo's are pretty good with just a tune+exhaust.
