Default JB4 Question

I'm shopping for the JB4 tune and just wanted to know before purchasing if the wireless smart phone kit is necessary/worth it. Is it like a tablet module you use for custom tuning? Just looking for some insight before the green light

I highly recommend the wireless kit. Yes, it's expensive ($140) but the convenience of being able to wirelessly make changes from your phone instead of connecting a laptop and cable is worth the cost IMHO. You will need to also get the JB4 Mobile app for your phone which is another $28 in order to take advantage of the wireless connection. Check out the app to see what all you can do with it and the wireless kit. The kit itself is a small BT dongle that you'll have to connect to the JB4 but it's simple to do.

I won't bother listing all the features of the app as you can read about them for yourself. I bought the dongle and app and they are the only way to go if you install a JB4 in your Q.

I agree with A5 that if you get a JB4 (what you're asking about), splurge for the BT and App. If you think you would be happy with a JB1 (really named Stage 1), then by all means, keep it simple, get a JB1. Really the only reason to get a JB1 is if you are on a budget and you have a Red Sport and you're completely happy with keeping the boost at 3PSI over stock. But if you are Silver Sport and/or are looking to start changing and customizing maps, step up the JB4 with BT. Don't mess with the data cable. You can start with a JB1 and go JB4 later if you'd like.

I strongly recommend getting it, you’ll be able to log your runs and see how your car reacts to the maps you choose. Everyone on here prefers map 6 due to being able to pick your own parameters and you’re able to taper your boost after certain RPM ranges. Ask Avedis53 and he can explain why that is wise and how it will benefit your turbos in the long run. Either way, that extra money spent is WELL worth it

Like everyone else said, its well worth the additional money. Not only can you update the device with just your phone over bluetooth but you get real time data as well as real time data logging. Data logging will ensure that your car is not getting overworked or lean while under WOT.

Well put! i appreciate the input from everyone and also am poised to ask the question though will this also work on a premium i see the website says Q50 RS and SS will this harm a premium if installed or be less beneficial?

And on the topic of purchasing Fuel wires, is this also for swapping over to E85 ? or for adjusting fuel air ratio as it mentions

Did you also get the fuel wires? and can this be used on a premium as well?

same engine so no it wont hurt it. Fuel wires are most beneficial when running ethanol blends up to 30%. A few people have mentioned they are useful for 93 pump gas. Basically fuel wires trick the ecu to provide less fuel so you run a leaner afr, the 3.0's run pretty rich (which is good and safe) but you do loose some HP for running too rich.

Your Premium has the low-output VR30 that the SS does and the JB4 will work just the same on it.

To run E85, you'll need to change your fuel pumps to higher output after-market pumps and perhaps make some other mods (CBE, downpipes, etc.) in order to maximize the power output. If you're thinking of going that route, you really need to go with a Ecutek tune instead of the JB4 to fully take advantage of E85, IMHO.

Ask MWH on YouTube about going with E85 mix. He's now going back to pump gas. He has a new engine, believe it or not, under warentee.

I am sticking to pump gas. I have not ruled out the AMS RS600/RS500 kit upgrades, at some point. Still pump gas. Many less variables to manage.
