For me, D was the hardest one. Was able to get it from the top, but got scraped up pretty good doing it.
I don't know how anyone can get down there with one hand and screwdriver to disconnect it. I studied and practiced on the jb4 connector, then went in blind and was able to disconnect it with my fingers or thumb, I forget which.
The bluetooth dongle had to be pointed towards the cabin straight, I had trouble connecting otherwise.
The obd cable, I taped to a 110 wire and snaked it through from inside. Didnt remove the battery

I just ordered a downpipe. I've been on map 2 since upgrading from JB1 to JB4. Is it time to switch to map 6? Should I switch to a stage 2 flash tune after installing the pipe?

I put a torch to a Phillips screw driver then punched a hole in the gromet.
My settings were very close to yours if not what you have. now i am probably the same as map 2. do you know what the lower rpm settings are for map 2? I think i am fairly conservative down low.
I only did one log on map2, so I don't know how good the reference is, but this is what I have:
3397 3.0
3679 4.0
4092 4.1
4295 4.3
4581 4.5

No need for a flash. Just go to map 6 and start making adjustments and log them. My friend been tweaking his for a while and he is doing quite well with it. I have the 1.8 and I'm pushing more boost above 4,500 then most stage 2 flash tunes. The beauty of the JB4 is that you can dial it in for your car and your climate. It's not a one size fits all

Why not go to map 6 and just dial in the what you want. Also, which I'm sure you know by now, doing a full pull from below 3,000 rpms will show more accurate readings of what's going on everywhere. You can definitely run more than that. I'm making more boost on the 1.8 with the little turbo

I am well aware of map6 as it is what I run now. Just wanted to show a map2 log to show what the settings were for it.

I can not use more boost than a flash stage1 in my GTI at 5.000 forward. Up to 5,000 it responds well to JB4's push but then not.
Note this log:
My current setting is this:
1500:1
2000:2
2500:3
3000:4
3500:5
4000:6
4500:7
5000:7
5500:8
6000:8
6500:7.5
7000:7
Target in this range is 7.8 psi but the difference between the ECU psi and the boost is 5.3. My car has worked with this map at a peak of 21psi falling to 14/15 in 6.000, is much smaller than a flash.
I would like to improve this range of 5.000 forward in my car but I can not get satisfactory results.

I've found the same issue with using the additive. I run absolute and set my targets above the boost I'm trying to hit. I'm hitting +11.5 psi over what the ecu is requesting this way. On additive only it always fell short. Especially up top
Can you post a log using your absolute settings?. I thought people were having issues with hitting target using absolute, so additive was better for hitting target boost.

Without a downpipe you will not be able to generate the kind of boost you are requesting above 5000 RPM.

I tried the absolute map, but it is far from the target too.
I think George speaks to disregard the psi when using the absolute map. Maybe the DME BT is the correct one to read the right stock boost on the absolute map.
Difference between target, boost, DME BT and ECU PSI.
