That's one of the main reasons the few extra thousand is worth it for me over the other trims. Just don't get the same feel and character with the turbo 4. Same reason why some would rather have a v8 than a 6.
Looked like 4:44 not 4:38. still a ways to go. Will be better with downpipes & some E85.
The video says 4.44, although 0.06 second difference is jut nitpicking at that point. Funny, nobody cared about 0-60 times in track-oriented car forums. Haven’t seen people so hypnotized with 0-60 times since the EVO vs STI days.
OEM downpipe already flows very nicely. Some aftermarket ones yielded less power on the dyno. Only other thing exhaust related to get more power would be running catless with a proper tune.

The only time most guys here care about 0-60 & 1/4 mile is when it looks like the Type-S might actually be competitive to something. Care, don't care its like watching a tennis match with the heads going back & forth. Its one of those things that make Acurazine so much fun
Not sure its nitpicking but the Dragy actually says 4.44 not 4.38. You want it to be 4.38 so be it for you.
Regardless this chart says the DP's do help to 392.25WHP. Typically you cannot run Map 2 pure stock so DP & a few gallons of E85 dumped in. Don't know what the actual mix was as they did not say how much 91 gas was in the car. They were trying to simulate 93 octane.

Run the vid its the single item at the top in the center. Maybe something else but looks like a 1 foot number since Dragy carries both.
Uh are you talking about the video preview/thumbnail? That’s just a single frame that gets selected by Youtube; it just happened to be the frame where it was at 4.38.

Payam from BMS said stock map with the DP on the test car actually made less power than with factory downpipe. PRL decided not to make a downpipe for the Type-S after seeing how well the stock one flows. The graph you showed is DP vs DP + JB4. Yes it is common for tuners to blend E85 when their region does not offer 93. Full E85 is asking for trouble in a number of cars.

Full E85 is asking for trouble for a number of cars. 400whp+ would be interesting to see for Honda’s transmission durability. That’s taking a lot of risk in longevity/reliability obviously.
I don't think most who buy a type-s are going to do much of this type moding. If I was a vendor would not do much of anything that required fabrication.
Now back to what I said. Map 2 = DP. As long as I remember going back to 2011 when I beta tested for them MAP 2 required downpipes. Map 1 never did because they did add any value since Map 1 was a pretty soft mod & not stressing the exhaust system. Looks like from the Map 1 to Map2 nothing has changed other than all models require DP to go to Map 2.
IIRC Map1 took my car from 319/321whp to 355whp. Still have some of the graphs. The only exception I am aware on DP was the 2011/2013 335is which ran the N54 not the standard 2011/2013 335 with ran the then new N55.
Going to custom Map 2 without DP I did a max of 410 WHP with 30% E85 in 70% 93 octane that contained an unknown amount of ethanol up to 10%. Alternate was 50/50 mix 93/100 was similar. Was starting to test straight 100 on a stacked JB4 Piggyback over a COBB flash.
That was about as far as I could go without DP which I had no intention of getting. I was also still running the stock intake system. Did not get much further into it as car was sold for a 435 Coupe with the factory mod power package in 2014.

Ohhh I get where you are coming from. The extra power from 350 to 390 was from having the MAF connector now. According to BMS, there is still more power to be made from tuning alone.

Yeah many don't realize how important the proper MAF & positing can be. In the FORD Racing, stripped down, ECU crate Coyote V1/2 it has to be installed in a 3.5" sleave inside the typical 4" CAI tube. It also has to be installed at the 9 o'clock position looking from the drivers side fender at a specific distance from the throttle body.
Understand the 3.5" reason but no idea as to the 9 o'clock thing other than guys have run into idle & stalling problems when its in a different orientation typically 3 o'clock. Version 3 of the crate Coyote does not require the sleave although it has the same size throttle body as V1/2. MAF location is the same as V1/2.
On the DP other guys in the beta for the 335is did go to DP. My best runs not the same single run was 12.004 & 117.630. Both the other cars with DP & CAI's ran to the upper mid 11. second range @ 121mph+

Those who are looking for alternatives to JB4 or a proper flash tune, it looks like DRob from IMW is working on a Ktuner tune for the Type-S. Always excited to see him or Vega(phearable) work on their tunes.
Placed my order for the JB4. I'll post reactions once I get it set up.
Did you get the whole package in including the smart phone app? If you are going to dyno it & have access to a DynoJet unit contact DynoJet & see if the still offer the software to convert the Dyno logs into charts & graphs. I kept all of mine on a data key so I could compare the run to run details not just the Dyno graph.
This enabled me to develop some of my own programs.

Yes, I ordered it with the Bluetooth module. I remember a comment you mentioned in the past about that being useful for getting updates. Looking forward to the logging capability. Have 93 octane readily available where I'm located so should be good with MAPs 1 and 2.
Does race chip make anything for the Type S? I'm curious. The GTS Black gives a nice bump in power without having to drill through the firewall and all that.

Sounds good best of luck. They will update the unit free of charge as long as you have it. Use this site for support, others with the system & updates to the package
Out of curiosity, what made you pick JB4 over KTuner?
Just looking for a slight improvement over stock, the ability to change settings quickly with an app on my phone, and less invasive while under warranty.

Gotcha. Just a heads up, if something goes wrong like engine starts knocking and they run a diagnostics, they will know that you had altered ECU parameters, regardless if it was a flash tune or a piggyback. I personally learned the hard way with a previous car that had a piggyback.

Yeah, I'm aware of the risks but still felt it was a simpler approach compared to the other tunes (when they become available). I also like the ability to leave it running with the stock parameters too.

The gains from it look like fun. Enjoy and keep us posted!

If it still runs like the old units you can make a lot of on the fly changes with your steering wheel buttons like changing maps, hijack gauges etc
Installed it today and went for my first few drives with maps 0 and 1. No problems with either and logs look good so far. I enjoy being able to see the data on how it is running.
Definitely pulls harder up top. With map 1, I'm seeing a boost increase of around 4psi from 4000-5800rpm. Drives like stock under normal driving conditions.
So how has it been with the JB4? Have you tried map 2? Overall driving impressions? Do you have a dragy to do some comparisons?
Overall really pleased with it. Just started using map 2 today. You can definitely feel the increased boost as you get into the throttle. No draggy yet, but I might pick one up.
I was happy with car stock, but this really changes the way the car feels, but only when you want the extra power. Under normal driving, you don't notice much of a difference.
My only complaint is that I wish the wiring harness was an inch or two longer. A little bit of extra slack would have helped. I might take another look to see if things can be repositioned. But the box fits snuggly alongside the intake box.
One other random observation, I noticed the intake air temps were only about 10-20F above ambient, even during an extended drive and 20-80mph pulls. Curious to see how that looks once the weather warms up

yeah I agree about the wiring. to make it look really nice an extra foot of wiring would've been perfect, but it does fit really snug and nice next to the intake box which is nice. Did you run the OBDII connector through the firewall? it wasn't too difficult. maybe 5-10 minutes.

Not yet. I have it going through the door for now. For the firewall, did you move the rubber gasket to the side or fit it in along with the other wires?

go inside with the bundle, you dont want any metal rubbing against the wire. There's room inside but it takes a bit to get through on the motor side because its sealed. Just use a tiny metal rod, take the end so it isn't sharp.
Found something that I'm not crazy about. I've been driving around in map 2 for the last week or so and I don't like how it shifts at higher rpms. The power is nice, but the shifts are a little too rough. Switched back to map 0 to compare and it was buttery smooth. Might try map 1 again to see how it it feels.
Looks like this has occured with other platforms in the past with JB4, so hopefully a future update can address this.

Good observation; do you believe the rough shifts are from the increased power? Unless I’m wrong, the JB4 doesn’t control any of the transmission functions, does it?

wonder if anyone else has any input on this. I’m thinking about getting and installing this for my mother as a side gift since she just got the type s and loves it. Are the shifts noticeably worse in map 1/2 vs oem, how does map 1 compare to 2 in the shifts? Im guessing this only happens when you’re WOT but if not then this might be a genuine dealbreaker for me.
It's not as noticeable in map 1. It just feels like power is either being cut or the transmission logic isn't expecting the increased power/boost during shifts in the higher rpms. You just feel more "shock" in the drivetrain during the shifts. When I went back the map 0, it was a very noticeable difference (in a good way) under moderate acceleration. You also notice the loss in power going back to stock, too. But the shifts felt a lot smoother.

Ok thats good to know. Is there a loss in power between shifts as if there is a delay? Or does it just it just throw you into next gear hence the “shock”. It sounds like everything is working properly tbh, the trans was made to shift a certain way when parameters are met since the piggy is lying to it those parameters are actually not being met, and if this doesn’t happen in manual mode when using the paddles or happens to a lesser extent then I’ll probably end up buying it still
well theres an ignition cut when shifting. maybe its like same type of jolt you'd feel with a manual trans? remember, you're probably adding 20-30% power with maps 1 and 2.
You may want to upload a datalog to N54tech forums and have someone from BMS take a look at it. If I can recall, the maps are still in beta as BMS just strapped a Type S on the dyno, made a map, and then just released it to the masses without doing widespread long term testing. So current users are the beta testers.

Yep, I'm doing that. They already replied with some adjustments to try making.
