Used JB4 piggyback tuner for Mercedes M260 motor - A35, CLA35, GLA35 W/Bluetooth
 

Hey all, used to have an account here back when I had my '02 SLK32, been a minute since then. I just traded my '20 A35 and have a nearly new JB4 which I purchased in August of this year. It has the Bluetooth option, and works great for changing tunes on the fly, viewing/clearing codes, and has a nice guage display for everything from boost to ignition advance/retard. Definitely added power, never had an issue with any codes or CELs.

Fits Mercedes M260 motor - A35, CLA35, GLA35, GLB and A250.

I am in Florida, and willing to ship anywhere in the lower 48 US states via a trackable method with signature required, cost will depend upon where you are located. Payment must be via a reputable source such as Paypal Goods and Services.
