Exactly. They have more experience on these platforms than most and have been providing solid tuning options for many years. The app is solid and like SCCA Racer was saying it is worth the extra money to have quick access to everything and change maps on the fly in 2 seconds.The jb4 is a tried and well tested piggyback that has been used in thousands of cars. I would be hesitant to use any other due to it’s proven nature.
Part of me likes the idea of having that data...most of me know I'll never use it.You will be SOO hooked on the BT connection if you do it! You don't necessarily 'need it'... you can use the USB/Serial port feature... but it's so nice to just 'change on the fly'... not to mention monitor all your items, temps, boost, etc...
As a long-time MHD user on the n54 platform, I'd recommend the JB4 for the Zupra. MHD had years on the n54/n55 platforms to build up it's feature set to be competitive but the on-the-fly map switching, easy meth integration, and its existing marketshare in the m240i market make it a better option than MHD and I didn't even know about the locked DME issue until reading this thread. I'm not super familiar with BM3 but have known dozens of BMW friends who used it with great success but last I heard it had a reliance on wifi to do license checking -- which isn't super helpful if you're in a parking lot or on the side of the road and need your tuning/logging/flashing/code-reader when the car is down and out of range of wifi. JB4 is an always-ready solution with simple controls and can always be disabled in pass-through mode with a few clicks.
Fair enough. The only piggyback to get is the JB4.You guys should really be careful all these piggybacks, just remember none of them iirc have any timing control and relies on the ECU to pull timing and save the engine. I can see now, that there are going to be vendors popping up all over trying to do tunes for these cars, with no knowledge of the platform.
Same thing happens regularly on the BMW side. Just be careful.
i am ready for a downpipe, I just don’t want a cel. If I knew I could get around that, it would already be in the mail.Now just to accidentally order a down pipe, then full exhaust, then all new turbo haha
