Description

Thundermax 309-589 ECM Integral Auto Tune System EFI Tuner Harley M8 18+ Softail.
Had this on my 2019 Harley heritage FLHC.  Awesome tuner.  I sold the bike and pulled this off.  I was able to tune my motorcycle myself with any combination of parts, and it's constantly tuning itself!
PLEASE UNDERSTAND WHAT YOU ARE BUYING BEFORE YOU BUY.  YOU NEED A LAPTOP AND YOU NEED TO DOWNLOAD T-MAX SOFTWARE TO INTERACT AND TUNE WITH THIS ECU.  IT IS VERY COMPLEX AND TAKES PATIENCE AND UNDERSTANDING DO NOT BUY IT AND THEN COMPLAIN TO ME IF YOU DON'T UNDERSTAND HOW TO USE IT.  Any dyno tuner can use this to tune a bike it replaces your computer entirely.  Also it won't flag your ECU that it's been modified like a power vision would, which immediately voids your Harleys warranty.
Came off my running motorcycle that never saw the rain never spent a single night outside by itself, well taken care of.  Was on my bike for one year about a thousand miles.
