Up until bootmod3 came into existence there were two popular ways of tuning the BMW F series, using a piggyback device to add boost and sending your ECU (DME) out for a one time flash to a tuner of your choice. With the piggyback the end user has partial control over the boost the car is running but no direct control over any other engine parameters such as ignition timing, lambda targets, fuel pressure targets, torque/load targettingtargeting, throttle mapping, valve timing and duration, among others. With the one time flash some tuners were providing the ECU would get reprogrammed on the bench and many of the parameters above would get adjusted. However, if the end user wanted to customize their tune for different modifications, octane levels, go bigger turbos, built motor, datalog how the car was running, to get the most performance out of their car there simply wasn't any way of doing so, until now!

Can I run E85 or meth and do you have OTS maps for these?
Yes, they're currently in beta and we'd love to have you on board with us going through testing.
Do you offer backend flashes to run with a JB4?
Yes. In fact our OTS Stage 1 and Stage 2 maps are great backend flashes as they raise load and torque targets far higher than stock allowing the DME and TCU to run as close to actual values as possible.
How do I datalog?
Using the bootmod3 mobile app and agent running in the car while connected to the bootmod3 servers (cloud).
Can I use my JB4 mobile app with your flash and log with JB Mobile?
Yes, absolutely.
Do I need to always have a laptop with me in the car to run the agent? Do I need the device always plugged in?
No. Agent that runs on a laptop or hardware device is only required to be used if using the bootmod3 app features. Otherwise, no need for anything to be plugged into the OBDII port.
What's the difference between bootmod3 and JB4?
bootmod3 reprograms the vehicle's factory engine control unit (DME) and in some cases other modules such as the transmission control unit (EGS/TCU). JB4 is a piggyback device that works in tandem with the DME to offer some of the features that may not be currently available with the factory DME (e.g. meth or secondary port fuel injection).
Can I tune my own car with bootmod3?
Yes! You can go into the Stock Tune and do 'Save As' another map so your stock tune stays in tact and you can start tuning it yourself or with your preferred tuner/shop.
Here are some videos created by Cary Jordan, one of the tuners using bootmod3's custom tuning features:

Will this void my warranty?
As with any aftermarket hardware modification on the car or any tuning, there is a chance the dealer may refuse or void the drivetrain portion of your warranty. Many dealers are highly tolerant towards modifications and if you don't have one, find yourself a friendly Service Advisor ;)
