I have 7 ECU tuning cables left for sale, for use on US model M12 and M400. These cables are produced to exact design from MBE using mil-spec 0.5% tolerance components. Each cable is tested on MY personal car before I send it out. Cables work perfectly both for computers with RS232 ports as well as USB ports with a serial to USB converter.

$100 each plus $6 shipping. If using Paypal, please add $3 for fees. Thats $300 less than what other vendors are selling them for.

Its unlikely Ill make more of these once theyre gone, so get them while they are around.

Questions or to purchase one, message me here or email jpwhsv@gmail.com

Thanks guys!
