Emira JB4 Tuning Now Available for I4 & V6 Cars!

[Eagle7]

I made mistakes and thought I was lined up on the front bolt while threading it in, and got frustrated with the bracket flopping around, so removed the rear bolt. Only to hear a thunk as the bracket settled and moved. I struggled, tried to manipulate the trunk-lid to re-align.

Ended up popping the Vent panel off so I could see the bolt holes better and know where the screw was coming in from. Highly recommend that if you are struggling.

How did you pop the vent panel off? Is it just clipped in place?

Well I got lucky and found the bolt. After removing the Eventuri I was able to see better. and it was sitting down in between two hoses, so I was able to retrieve it with a flexible magnet wand. I was finally able to get the bracket installed, but I'm pretty sure the socket that dropped went all the way down to the under pan on the bottom, so I'm still going to have to get the Quickjack and lift the car to remove the under pan.

Since I had the Eventuri out anyways, I went ahead and did something I'd been thinking about with all the discussion about increased heat in the engine bay due to the increased performance. I heat foil wrapped 2/3 of the body, the part that holds the air filter and the MAF. It's a shame to cover the beautiful carbon fiber, but unfortunately where the unit sits you can't see it anyways so it really doesn't matter. The beautiful shape is also surprisingly awkward to wrap, so I did it in many small strips, but it got the job done.

Yes it's just friction clipped in place. Start at the top near the roof and find an edge (pry tools if you must but I just used fingers) work an edge and just pull up gently and it will come surprisingly easy.

Do you think wrapping will make much of a difference? Got me thinking that maybe I should do the same for my GRP intake before I install it?

@Payam@BMS any progress finding a CANbus signal somewhere in the engine bay? I haven't caught up with the thread so apologies if this was already answered.

The engine bay gets really hot, and that's just stock from the factory. Adding more power and performance isn't going to make it cooler. I noticed how hot it really gets when I was adding heat reflect material under the trunk, since it gets so hot in the trunk. I thought it was mostly from the muffler below it, but when measuring with a laser thermometer I noticed the back wall of the trunk was 100 degrees. The trunk floor was 84 (what I had done had made a difference) but the back is also quite hot, and that's with a factory heat shield in front of the back.

I've been thinking about heat shielding the Eventuri ever since, and decided to go ahead and do it. I had already heat foil wrapped the intake tube from the Eventuri to the supercharger, so now everything facing the engine compartment is wrapped. With the JB4 measuring incoming air temps, and with their app I can easily see it on my iphone now, I figured it can't hurt.

I've even wrapped the JB4 unit, since where it's mounted is in the heat flow stream from the engine bay up through the vents above it. I know electronic components and heat do not go well together. The roll of heat reflect tape I had bought had a lot of extra after wrapping the tube to the supercharger, so I've been using it where I think it might make a difference.

Since you can't see the air intake housing from outside the car anyways, I'd say wrap it. It can only help, especially if you're poking along in slow stop-and-go traffic, or just sitting at idle.

Looks like you're smuggling gold bars fresh from the mint!

Did you have a chance to test the JB4 yet? I've been following your posts and am eager to hear your feedback. I've had my JB4 sitting on a shelf for many weeks now and just haven't had the time to install and test it. I also installed the Eventuri a few weeks ago and LOVE the difference in sound and to me the power increase is noticeable after a hundred miles or so as you had stated. I also have the GRP 3rd cat delete and milltek valve controller so I think our setups are very similar. Thanks!

Disregard, I saw your post in Kitkat's install thread. Very cool. I might install mine today

Put a towel on top of the Eventuri, and underneath the bracket mount location, so if you accidentally drop a bolt (or socket), you won't go through the ordeal of having to retrieve it from down in the engine bay.

ALSO, VERY important... do NOT remove both of the original bracket screws at the same time. Remove the one closest to the car interior first, then put the front of the bracket on and screw the bolt in tight enough to hold it, but still allow it to swing around. THEN remove the rear bolt, swing the bracket around and put the rear bolt in to secure it. Tighten both at that time. If you remove both of the factory bolts first, it's going to be significantly more difficult to install the JB4 mount.

I wasn't able to drive it yesterday, but tonight I'm going to go out and record a data log, then send that to Burger. If all's well or they update the tune, I'll update and then do a hundred mile run, then take it to the dyno shop, hopefully next week if I can get a slot for a dyno run.
