You could set the link to a folder, then just drop what files you want to share into the folder. Make sure that you allow the folder to have 'list' permission.



BTW, I usually don't comment on ISO updates, but WOW...so smooth...

Does anyone use the 4.2 option?
Are you getting any benefit? or, what cases is beneficial when not using the target of the dme?

Same here. Is that for those running G5 ISO only or is it for those running a BE flash as well? Which is better when running solely with a G5 ISO + bolt ons and no custom flash?

If for some reason..... say your traveling and can't get E85 or you run out of meth....... you want to be able to use the lower boost targets set by the JB4.

I do - feels like it's a little bit smoother on low throttle, especially if you have menu 12 up high to avoid WG rattle.

Just out of curiosity what are your menu 12 settings?

New thing for me in 27.2, hasn't happened every in any other firmware version, but has happened about three times in 27.2

During WOT runs, as I near redline the car will do a very quick stumble and lose power. All three times this has happened in third gear (on MT) but that could just be a coincidence. Also, I get more boost in third gear than first or second, for whatever reason. Not sure if that has anything to do with it. I run about 40-50% E85 and the rest 93 octane.

Anyway, a quick check of the engine maps reveals that this stumble is because JB4 has switched from map 5 to map 4 during the full throttle run. The second and third time the stumble happened to me, I immediately checked the map settings and saw that it had switched to map 4 on me, so it's definitely doing it during the WOT runs.

I do not throw any codes, and switching the car back to map 5 works just fine.

Is this some sort of bug, or is it a JB4 safety feature? Any idea? I would post logs, but I don't have an extension for my USB cable at the moment.

It will do that if AFR goes too lean, or fuel pressure drops below 7, among other causes. There is a setting "FUD = 17" that is designed to improve fueling on 335is models. You may need to enable that if turns out to be fuel trims related.

I'll have to run some logs then to see if that's the case, but I imagine it's fueling. Car is 60k miles and is running almost 50/50 e85/93 octane on the stock fuel pump. I imagine I'll have to upgrade the fuel pump soon.

ISO 27.3 Notes

1) Corrected a bug preventing throttle trimming from properly engaging in response to boost over target conditions.

It's not your car it's the 27.2 doing it. That is why I am going back to 25. Same mods same fuel same map. Had 0 problems

Is this something you should do as a matter of course with a 335IS or do you need a fuel issue first?

Generally only if trims are maxing out.
