Yes $160 plus shipping sounds really awesome.. I went to look for the pipe as well I do recall someone else having something on the X1 forums... Edit: I just went to look and it was the ER Racewerks downpipe which is.. very pretty, but I don't want to take out my front cat and deal with codes right now...

Installation of EWG wires on X1 X2 is not so complicated, after removing the right front wheel and plastic fairing, the EWG is quite easy to access. EWG is above BOW - see pictures. There is no need to remove anything other than the plastic engine noise cover in the engine compartment. The last image is a view of the firewall in the engine compartment

Terry wants me to get the ewg connectors , I haven't ordered them but from what I read the install is a bitch and you need to remove the plastic shielding by the windshield and above the Turbo and intake inlet pipe to get access to it , on my m235ix is tight as a virgin in there

You should put the bms intake back on. This will lower the boost. Boost is a measurement of restriction. Open up the amount of air, the less boost needed to move same amount of air.

For x2 it’s a different part number for some reason.

Oh I can't wait to hear about that midpipe!

I did a custom map 6 before with Terry.. Nothing special, all default map 6 settings that you should verify on the website (sorry don't have link handy). All I did was add less boost at the beginning, +1 All across the board. This was before we all figured out that it was the general boost limit (and my intake) that needed to be raised so I could go back to keep 1 or 2. Again... Map 2 for some reason has better throttle response and behavior, as well as the max boost. Even if I could get a little more out of the custom map (which I can't) then I like the daily driving behaviour of map 2.

Terry originally wanted me to do the ewg plugs too.. But I suck and couldn't get to the plug from the top. When I changed the tire for winter in did notice the box through the wheel well and I thought about trying it again, but I didn't remove the splash shield and it was still pretty tight and decided it wasn't worth the effort again

At this point I'm really interested in that mid pipe ( or to get an front splitter for looks ). We'll see! My front pipe does look exactly like the setup you have on your 2 series.. Just the bends hopefully it's the same... I do want more pics of your install before I pull the trigger!

Turned DWP back to zero. No more boost spikes but all is still good as t had been for months. I do agree with DWP at 70 the car pulled more but peak boost was higher and hit 30.5 via my AEM gauge and no fail safe kicked in. Now I am back to predictable. Staying with latest firmware though.

[xcelir8bmw]

26.5-27

[xcelir8bmw]

Warmer weather and DWP off. Hit 30.2 spike a few times, consistent 26.5ish. Car still great!

[BlownLSX]

Add me to the list of jb4 owners. Gonna sell my jb+ once the jb4 comes in. I want those sub 4 sec 0-60 times.

[xcelir8bmw]

True dat!

[BlownLSX]

What is everyone's settings at? The DWP hit boost safety immediately. May go back to V18 to just not have to deal with it.

[xcelir8bmw]

version 19

dwp zero 0

30 safely

map 2

all running good like a champ

[BlownLSX]

Thanks guys, ima set that up later. Do some logs with the good quality 93 I have here.

[xcelir8bmw]

82 today

tried backing firmware to 18

tried reducing safety to 29 from 30

in map 2

failsafed to map 8

went back to 30 all good

went back to firmware 19 all good where I started

aem boost gauge shows more accurate blip to 31 or 32.4 bit that is the diff tap than jb and matched tdi

all stable here with the drop in aftermarket pipercross filter

26.4 to 26.5 continuous over stock

can you notice any difference between the 2 firmwares beside the DWP setting in v19 ?

Also on a side note in the hot temps today I had on map 0 checking and saw boost of
23 - 25psi peak stock .

Decided to dip into map 3 and see what happened. No safeties hit. Car spins way to bad for a good 0-60. On V19 but DWP is at zero.

To see how much timing the car is pulling as it will let u see what's going on

IAT temps below 110 don't bother me. No meth needed for that. Saw a peek of 4 timing when it spiked to 28.20 psi. AFR strong at 14.5 the whole time. These cars desperately need a downpipe.

[xcelir8bmw]

v19 seems fine

I met a guy yesterday with a brand new mini gp3 with the same engine and tranny as ours .

He's running 30lb boost on map 2 with an exhaust and intake and an arm methanol kit .

With the methanol kit his JB4 is able to run that boost without any high iat temps or over boosting and he's able to run high boost without any timing being pulled .

It's pretty awesome 😎

I have a monster meth system on my z06 but I'm not going that far with the daily. Would like a downpipe and then that's it for performance stuff. I'll do more suspension as things come out. Then cosmetics.

OK. For the hell of it, I put MAP 1 into my JB4 down from MAP 2. Had my family in the car. Drove on the highway. And the weird thing was that in MAP 1, the car 'appeared' to drive 'as well if not better' than MAP 2. Meaning, well, I couldn't punch it due to traffic to see what my max vs. settled boost was via my AEM gauge, but when I was 'on it' a bit, I'm thinking it just 'drove better or smoother'. I think it was only down 1 PSI like 25.2 vs 26.5 in MAP 2. Nonetheless, leaving it in MAP 1 so when I personally myself drive the car, I'll make my mind up to see what was what. It was 50 degrees out. Word.

[rice_rocket88]

Yikes!

[xcelir8bmw]

Glad I went back to zero. Going to be testing out Map 1 tomorrow.

rainy days, no luck...

21M235IXGC did you ever put in the mid-pipe?
