Thank you. Will do. Good concrete suggestion.

BTW....Zippers said problem is speedo not Tmax. Harley says...."you violated warranty- F U and Ho away....unless you want to trade-in that POS." Nice huh.

i just pull the code, delete it & ride the **** outta it

Zippers knows that there's a glitch, but i don't think they know how to resolve it
What code? Tmax code? Is there another way to read and clear DTC codes.

I called Zippers and asked them about it and there response was that it is a known problem and they have no fix for it. I just figured small price to pay for the increased performance. My bike ran normal both times it happened i have had been running the Thundermax since 1000 Km and has worked awsome runs great better performance i have not noticed any difference in fuel milage only had the two small problems. I have not contacted them concerning this issue as it happened once about a year ago and i just forgot about it untill it happened 2 days ago. i am not even sure it's a problem with the Thundermax just a guess. keep me posted if you have any luck figuring it out.
I have a procedure for restoring your DTE. If you want it...PM me and I'll post it.

On Thus...I am gonna pull sensor...Tmax..O2 Sensors...battery...fuses....and go through it all..damn shame the Elkins gang won't tell us there is a known glitch.
