We all have our opinions on the best speakers, amps etc ,,,,, and it has been hashed on this forum for many years!

However, when it comes to flashing the 14-22 Harley radios, I have tried ALL of them available using the Harley digital technician, the Techno-Research digital tech and Diag-4-Bike digital tech.

The J&M Stage5 radio flash, lowers the output of the Harley radio, flattens out the EQ, activates the front/rear fader control and activates the distortion limiters programmed inside the Harley radio.

NO OTHER Harley radio flash combination that I have tried does all of this, and some of the flash combos are downright RATTY sounding, high pitched and lack bass response. (I wont name names)

Just my 2 cents worth.

 

Please post the RTA results of the flash for us to compare.

Thanks in advance!!

No sponsor bashing

 

Where can I get this flash done? I also would like to see the RTA screen on this flash.

 

Technoresearch and Diag4 can both flash J&M

 

Correct, the Techno-Research and Diag-4-bike digital technicians BOTH have the J&M Stage5 flash listed in their menu options ,,,,,

This is FREE information and J&M receives NO $$$ from either company when users choose this J&M stage5 custom radio flash option ,,,, If you dont like the results of the flash then simply choose an alternate ,,,,

Techno-research also offers a less expensive self-flash technician module that marries itself to your Harley's VIN # and you can use it to update your Harley radio flash any time you need to (Like when your Harley dealer alters the radio flash without your permission)

The self-flash kit can also be purchased here https://jmcorp.com/Techno-Research-A...024_p_311.html

back up your findings!

 

Still waiting on the screenshot of the RTA for JM flash

 

You're not going to see that. You'll have to take his word.

 

If I have to take his word, he'll have to take mine.
I have the "best" Harley Audio System available with the "best" flash for all 14-22 Harley Davidson Boom systems!!
