    ECU Tune For 2017 B36

    Posted by Ronald Collins on Apr 4th 2018

    Great tune. Torque and HP increases are more noticeable than previosly used "piggy back" unit. Car is a blast in Sport mode with an overall improvement in driveability in both modes. Better gas mileage. This is the tune the car should have come with from the factory.

    ECU Tune 13 Countrtman

    Posted by Josh C on Nov 28th 2017

    Great tune. Can’t say I notice more power but the tune did get rid or my DME internal fuel plausibility code that would put my car right into limp mode after 3000rpm. Also the car is not reactive when it comes to throttle response. That’s what I sent it in for and I’m more than satisfied. Once I bolt on some goodies next year I’ll be sending it back for a more aggressive tune.
