The website has nothing for C43 install. The best video I found is this one https://youtu.be/JEWpMZVTgwk
however he only explained where 3 of the 6 clips go.
Anyone here have some more insight?

Herrerrera

also is it one of these two holes where the obd2 reader goes through the firewall? If so, I've tried to feed it through but it doesn't come out anywhere.

I hope people reply. I am looking to get the JB4 abs assume I will need help. I’ve seen a few videos that seem to skip some steps

have y reached out to BMS. I was hoping they withd guide me through install issue.
good luck.

MaverickC43

And I assume u have looked through other jb4 install posts.
I haven’t looked into then with great detail. Bc I’m not doing the install yet.
but they’re out there.

Herrerrera

Okay ignore all that. It's installed. Now how do I link it to my Bluetooth? Will it just be on map one until I figure out Bluetooth? Is there an App or something?

MaverickC43

Awesome. Keep us posted. I’m interested in how much u “feel” the difference.

Herrerrera

I'll show real 0 to 60 and quarter mile results👍

Herrerrera

Just got back from test drive. Car feels super slow and is not boosting at all.

MaverickC43

That’s no good. 😩

MaverickC43

BMS give u any ideas if what the problem is?

BMS

Sounds like you did something wrong then. If you need technical support email in installation photos and a JB4 log to support@burgertuning.com.

A couple of questions, do you have everything connected properly?

Did you successfully connect the wireless Bluetooth piece to the main box?

Have you successfully downloaded and paid for the JB4 app?

Has it done the proper handshake between the app and the bluetooth devide at the JB4 box?

Fill us in.

Herrerrera

Yes wiring harness install is extremely easy and Is impossible to mess up. They're all connected for sure because they're always a bugger to get back off. Bluetooth attachment is connected properly, obd2 plug connected. downloaded and paid for JB4 app. I've shared pictures of the install with them Along with a close up of both sides of the circuit board. They sent me a new circuit board that arrived today. I replaced it and I'm still having the same issue throwing the same two codes.
They now think it has to be a faulty wiring harness. So I shipped back the whole unit already. Once they receive it they'll send me a new kit and we'll see how it goes I'll keep you updated.

Here's a 1/8th mile pass I did today.
was hoping to show some stock vs JB4 map 1&2 to show some real numbers. Hopefully soon enough.

I recently installed mine and did a firmware update, had no gauge read out on the app, so BMS support is suggesting to also send it in the for same reason (I haven't yet but need to.)

Just curious - Did you notice any butt dyno gains after you installed it at all? The only gauge that worked for me was the Map setting and I later learned through support I was apparently getting some gains, similar to their stage1 tune, but the maps weren't being set. I felt like I had a small change after installing it, at least on lower end acceleration but could've just been me.

Herrerrera

All gauges worked fine. But I literally had zero boost. Car felt like it had 120hp

Grab some logs. That will let BMS see whats up. I developed a boost leak after the first run of map 1 after install. Upper hose on the intercooler started coming off. Had to upgrade to t-bar clamps.

What engine code are you throwing with the CEL you have? I ask only because the video notes you are driving a stock car.

MaverickC43

Did u ever get the Jb4 working ?

Herrerrera

I don't recall what they were. I sent back the unit and I should be getting a new one any day now.

C43HeartBoost

Sounds good, keep us posted. To be clear, was the video you took in stock form (or with the JB4 in map 0) or with the JB4 installed (and not on map 0)?

Herrerrera

video was stock. If jb4 was installed With the issues it was having it probably would ran around 16seconds. Literally had zero boost haha

I'm excited to geek out on the difference on map 1 and 2 with the dragy. Also buying some 22lb wheels and interested in seeing the difference.

MaverickC43

Any progress with the Jb4?

Herrerrera

yes I literally just got the unit back yesterday. It hasn't rained here in Utah for 42 days. And now we have 3 days of rain lol. I can't get any good runs in. But car feels a bit quicker on map 1. And a LOT quicker on map 2. I shared my map 2 log with them to make sure it looked safe since Utah only has 91 octane available. And they said it looked great. I'll share some dragy 1/4 miles when it dries up.

drdrewdown

thank goodness for your rain. get your damn fires under control!
