Cobb removed the ATR and now it will come back updated, and you will have to pay for a training to use it! This sucks!


Does anyone have an Old Copy of ATR we can Download for the N55?? Let's go Forum guys!

JB4?

[Cory S]

I went from ATR to a JB4, and will never look back.

I've heard people have problems with JB4 and went back to Flash

Pretty much the exact opposite. People switch to JB4 and dont have problems.

Maybe several years ago, but the vast majority go to JB4 from the AP. A few people still prefer the AP because it is a bit smoother, but the JB4 has become very good in that aspect too. Having better control of AFR's is obviously great also, if your setup needs it. I am just waiting for MHD. That with the JB4 will be the way to go, maybe even get rid of the JB4.

I've been hearing so many things about MHD. When will our vendors get to selling them..Is there a thread for MHD info?

Here is a thread that discusses the subject.

2 of my buddies went from Cobb to jb4 on n54 platform. So much more reliable and smoother

[olivojoe]

So forgive my ignorance on this. I have been away from the blog for a while and am now coming back to this panic of abandoning the COBB and jumping onto the MHD. I have the COBB AP V3 running a somewhat perfected set of 93 pump and E85 tunes.

With the MHD, what hardware is required to interface with the car?

Also, what pro-tuners are offering support with this new platform? Is it just MHD?

EDIT: Sorry, didnt mean to try and hijack the thread, I actually meant to post this on a different thread......

[sd306]

I went to jb4 because of unsupported ROM and like it much better, for e85 it's way easier. But luckily there is the downgrade ROM option now so I kept my cobb for pure stage 2

I plan on going to JB4 while I wait for MHD. I have Cobb V3 now.

Idk who MHD works but I hear you flash from your phone or something..

Wedge and BuraQ I think are support

Would you like to trade Cobb devices and give me your ATR?

Lol at saying JB4 is reliable and smoother vs a actual flash tune , it is a piggy back system that has to trick the ECU, so there are moments when the signal hasnt been sent and you dont get that 'smooth transition' that you claim.

This. BMS has made so much money off peoples ignorance. Anyone switching from the AP to the JB4 is downgrading. Meth and isolated boost control is the only thing the JB4 is good for. You don't need either of those with a proper custom tune. Oh yeah and you get those cool shift lights

The JB4 firmware for the N55 E-series has tons of programming issues. It's like a beta piece of software Terry works on as a side project. What time he does put into it seems to be on the newer platforms. Why? because those are NEW customers and NEW cashflow for him.

Do people not realize the JB4 also doesn't work on all roms too? I couldn't take advantage of 6-cyl timing or log certain parameters with my JB4 until I updated my DME. Cobb is at least upfront about this whereas BMS doesn't tell you anything and takes no responsibility for the JB4's functions not working properly.

Out of the box I can see how/why JB4 is better ( I had it, it was great, but I could feel the inconsistencies), OTS Cobb maps for the N55 are terribad, so right there, I can see people disliking it, especially if you have the DCT, throttle closures and boost overshoot for days.

Once I get my Pure stage 2 installed, I am going to get an E tune along with a meth map as well. Ill run 50/50 with the meth map, and probably just use blue windshield washer fluid for my regular pump map (cooling reasons only)

The N55 E Series JB4 is as far as I know is the only actively supported tune out there. BMS has recently added lots of features including cyl 2-6 timing logging, 3.5bar TMAP support, back end flash support, integrated port injection
and TBI support, and several software updates. The E series N55 ISO went non-BETA a few months ago as well.

BMS is always working on all their stuff, even the older E-series N54 has received lots of updates recently.

Why do you constantly bash the JB4? We have heard it all before and I don't think you have used one recently. It has improved quite a bit from the earlier days.

Both tunes have their advantages, but most people are liking the JB4 better. Bang for the buck is a big reason, the AP price dropping helps a little, but you still have to buy a protune if want any decent performance out of it. Them taking ATR away from the DIY'ers hurts too. Yes a properly setup AP will be smoother than the JB4 and it can directly control AFR. Those are really the only 2 things it has over the JB4, but AFR control is pretty huge if you need it.

Here's to hoping the MHD is what the AP should have been, good support and user tunable. At least the JB4 has good support, unlike the AP.

Tl;Dr - both tunes have their advantages, so to each their own

[bNks334]

So, the JB4 finally added some of the features that a custom tune via the COBB AP has been able to provide for years? You point out that BMS is finally implementing these things, but how does that negate that COBB/MHD is also working to actually bring OBDII flashing to market? Where is this perception coming from that COBB no longer supports its current product? It's false. Their customer support is leaps better than BMS's.

I've experienced the flaws of the JB4 for myself over the past 2 months of use. I don't need to prove anything, the facts are all there even on the N54tech forums for anyone to see for themselves. Your high opinions of the JB4 can't change that. Merchants pushing to to sell JB4's can't change that.

I've pointed out some the the JB4's flawed logic myself as well as some of it current programming issues. I even had my posts deleted when I pointed out to a few users, who were having problems with passing state emissions, that you have to remove the JB4 entirely to get the emissions monitors to ready up. Despite the perception BMS gives off that you can just put the car into map 0, the JB4 still prevents the monitors from setting. I had to figure this out for myself after BMS ran me in circles for a week. When I figured out it was the JB4 their attitude changed to "oh well we said it's offroad use only." The product doesn't even work as they intend. My previous point was that the JB4 doesn't even work with all roms JUST LIKE THE COBB AP. This all circles back to my assertion that BMS is not transparent at all about the JB4 and misleads people as seen in this very thread

ISO may not be beta anymore, but it sure shouldn't be sold as anything more than an alpha test product. The JB4 is a piggy back device that does nothing more than add an entire layer of failure points into the tuning equation. My point stills stands that anyone going from a COBB AP to a JB4 is downgrading. The only reason to do this is if you upgraded you're DME to a ROM that hasn't been cracked for OBII flashing, YET.

I agree with this 100%, but for the aforementioned reasons I wouldn't ever encourage anyone to switch to the JB4. Like you said though, to each their own.

Lol, run the n20 tmap on the cobb
Control the boost by rpm with the cobb
Limit the psi in 1st, 2nd and 3rd gear

Dont hate on something that works wonders. I was forced to go cobb when the dealer updated my car and guess what. I like it better after having protuned maps with the cobb.

Cobb is also good for certain things it can, and both is even better.

I passed emissions with the jb4 on map 0

Also your engine mod list looks pretty limited compared to others running jb4, so how do you have better experience or feedback to provide?

[Cory S]

Just wanted to add that I also had to disconnect the JB4 entirely from the loop to get my emissions monitors to become ready. I left the CAN wires connected though. When I was driving to get the monitors ready, about every 5-10 minutes I would have 3-4 monitors go ready, then go not ready. Almost like the JB4 cleared the OBD2 system every 5-10 minutes, even when auto clear was supposedly disabled.... But I do love my JB4!!!

This is exactly the issue of being ill informed. The JB4 allows you to run the n20 tmap sensor because it scales down the load the DME is seeing. That is not how to properly tune a car. The same task can be accomplished with a custom flash tune. It just requires knowledge of the DME instead of trickery.

But, I am not here to bash the JB4, I am just here to share my experience and point out that the JB4 isn't all that it's cracked up to be. Keep on keeping on with the badass car you've built . Just pray the JB4 maintains proper communication with your DME while you're pushing all that power. It's 95f here and my JB4 cpu is overheating

Yes that is exactly what is happening on the latest software. It's definitely an unintended programming error (on map 0).
