    JB4 for 1M

    New on the forum and also fairly new to the world of tuning. I would like to have your opinion on a JB4 tuning for my 1M Coupe. I have read some of the info about the JB4 on burgertuning.com but would also like to have feedback from those using the JB4 on a 1M, or other models for that matter.
    Two specific questions:
    1. How is the handling affected by the extra power?
    2. Can the JB4 tune be detected when the car is brought to the shop?

    Thanks for your input and help!

    1. your car will handle great, just expect to get sideways with more ease.
    2. no it cannot, just look to see if there are any codes before you pull it out if you ever have to for service reasons

    The only way your handling will be affected by the extra power is if you don't have rear tires left! It is awesome!

    Handling is not affected at all if the JB4 works on a 1M eN54.
    Only the TC light will come one sooner due to more torque. I am curious if the overboost function of a 1M would still work with a JB4.
    If you put the JB4 in Map 0 it will pass through all info on the ODB2 port without interferring with it. I had my car on the BMW connectors at the stealer and they found nothing strange.
    Just if they pull the DME they will find your JB4. But normally there would be no reason for a dealer to do this.
    There are two theories to arguing with women. Neither one works
