Cobb AP OTS map 6AT flatlining fixed?

Planning on running the Stage1+FMIC map...

Did Cobb ever fix the flatlining issue on IJE0S 6AT when short shifted? I know the workaround last time I checked was to stack a base map + a piggyback.

Man I've been out of it for two years and there has been so much movement!

I guess running a JB4 + Cobb AP is obsolete now?

Hehehe, you virtually dont need JB4 IF your on stock turbos and soon it wouldnt matter if you have upgraded turbos. All this can be exclusively controlled by the DME with MHD Flasher. Here is a sneak peak of our testing on some Hexon turbos all the way to 30 PSI and perhaps more. Public anouncement will be made after all R&D is done and whats involved with the "package"

Lol what flatlining issue ?

Not to jack the thread but I was in the process of getting a custom e50 tune from wedge but now that MHD is out im leaning on getting that. I know there are more tables on MHD but is there going to be any noticeable power difference? I'm not looking to make the fastest n54 but I want it safe and reliable as well.

Thanks

BuraQ.... I'm hitting a dynojet tomorrow morning and I'm sure you guys are busy with getting the hexons dialed in. do you see anything that can be tweaked with my e60 v3 map from wedge? haven't heard back from wedge in a week

Wow, everyone ignored the man question and started throwing product in his face . To answer the op question, any Cobb tuner can fix your flatlining issue with a protune since Cobb no longer updating their maps. No piggybacks needed.

MHD is a new tuning solution you can look into if interested.

some ppl were lucky enough to have their flatline tuned out by a cobb tuner.....unfortunately i wasn't one of them when i ran cobb/ptf and we tried it all.

Did you try Wedge/BQ who solved it for several Cobb users before MHD existed?
