Any one with jb4 do it yet and everything's been fine ?

[josephx66]

Is this also available for the g80? Do you just apply the m2 cs engine flash to my m3?

Yes. Just read the tons of topics on this...it will give you all the info you need to know.

Had kubax86 do the CS DME flash this morning for me on my 2022 G82 M4 Competition XDrive. His service was top notch as always, and fast. Got me scheduled in for an appointment relatively the same day I placed the order. Had him do the CS transmission / DSC / diff / suspension / anti-dazzle / side marker delete late last year and was excited to finally be able to add the DME flash to complete the entire package.

Do note that I'm also running a custom Map 6 with JB4, using e30 for fuel.

My first impressions:

Startup - Engine note definitely sounds louder, deeper & more aggressive, especially on cold starts.

Idle - The CS flash will increase the normal engine idle post warm up, to 900 RPM, due to the much more aggressive CS mapping.

Throttle - With the higher idle RPM, this makes throttle response from the dig way more sensitive, and the car just literally takes off much more aggressively. I strongly suggest feathering the throttle now as the car just wants to fly off the line from the dig and there will be a stronger jolt compared to the regular competition map stacked with Jb4 Map 6. I do really enjoy the way the car responds and takes off from the dig now, compared to before.

Exhaust notes: Noticeably more aggressive exhaust notes, and louder burbles / pops / throttle blips. I do thoroughly enjoy this new features.

Mid to top end range - Power delivery is much more linear and smooth, but not as aggressive compared to the competition map stacked with Jb4 Map 6. The feeling that I can describe it as is that it doesn't push you back as aggressively in to the seat when boost kicks in at the higher RPM and gears, in which I do miss.

With that being said, I sent a log to my custom map guy, who has suggested increasing my FF values slightly. I have not tried driving the car with the new FF value yet, but I'm hoping i can regain that aggressive feel at the mid to top end range again.

Overall, I do recommend this CS DME flash especially if you are stock as its a relatively low cost "mod". I also do highly recommend getting the whole CS flash suite to complement the DME flash.

Did you or your Map6 tuner, see any difference in your fuel trims with the JB4 custom map 6 on E30 with the CS flash? Many people, who run the JB4, are wondering if this M2 CS map adds more fueling, so you can increase your E mix.

Is this going to be much of a difference on an LCI xdrive?

He didn’t mention anything regarding fuel trims when he reviewed my log. Only told me to bump FF. I’ll ask him about how the fuel trims look.

Yes, we apply it to g8x successfully. Power bump, increased throttle response, better sound and top speed limiter off are key benefits

We did on at least 4-5 cars with jb4 - owners reports better sound/throttle response and vmax off(186mph/300kmh)

Is the speed limiter fully off or just pushed up to 302 km/h (188 mph) like the CS?

Correct, pushed to 188mph.

If you would email me the log I’ll be able to tell right away if it’s fueling better

I’m getting the flash done Saturday and run my own map 6
But I’m also going to do dragy times for map 0 and 1-3

Fuel trims and boost actually went down a little, hence I was instructed to raise FF. He recommends not going over e30 with that being the case. I’ll send you the log, but I’ll plan on doing another log either today or tomorrow with the new FF value.

Would need to see the log, but if your fuel trims have noticeably gone down, then that technically means you have more fueling.

Where did this "add's more fueling" idea come from?
I seriously doubt there's any changes to anything, the afr is kept the same as before and the dme adds whatever fuel is needed to hit the afr at any boost level. This wouldn't give you any ability to add more ethanol, unless the fuel pressure was increased, but for 20 some hp that's doubtful.

What about the suspension? Is this a plus? A few posts have mentioned whether it is advisable (for lack of a better term)to run the CS software on standard dampers that may be valved softer. Would you get more bottom-outs or excessively rough ride? I don’t really know how these electronic dampers work in these cars

Wow, let me just say that this CS flash is amazing! I worked with bimmer-remote on the sale which was super straightforward and they were very responsive via their standard support mechanism. I connected with Kubax86 who provided very easy to follow and clear directions on requirements and the process, and the flash was done within 15minutes. Really cool guy, set clear expectations, and executed flawlessly.

Now down to the results... Okay, wow! Very noticable on pull and chirps the tires in first three gears on MDM with literally fresh pilot sport 4s's installed this week. BMW gauges maxed out on a full pull 530HP and 29psi... Not sure if those are hard limits on the display but they were at the limit. I also had the CS steering, transmission, and suspension flashes completed ... I need more drive time but everything feels smooth and slight difference noticable right off the bat with steering feel. I felt that the M2 had lots of little adjustments needed in day to day driving but I felt this was a bit more natural. That said, could be placebo and need more drive time.

I couldn't recommend Kubax86 any more highly... Great team and a pleasure to work with!

What’s up with first run not even coming close to boost target? Your fuel trims on both are still maxing out but only for a split second. 2nd run looks pretty good.
Have you actually tried lowering FF to 41 and then bump boost by .5 across the board?

Shoot me logs from today if you would
And I’ll share mine this Sunday when I get it and get some logs done

[josephx66]

Just got this flash done on my RWD g80. Everything feels great, car sounds a bit different, more aggressive. Can feel a little more power. Cold start also appears to be slightly less annoying now. Overall car just feels much more responsive. Great service offered by these guys. They were very flexible and accommodating with a few of my requests.

I don't think we've seen anything to prove fueling is better or even changed at all.

What do you mean cold start is less annoying?
