Are you sure about that? I may be wrong but I don't think any tuner can make the 6th speed light work again because it's a function of embedded firmware inside the ECM and I have never seen any consumer level product allow you to do that.
When WE (geezer and I) worked on this Idea of Changing the Clutch Gear to a larger one, Many of the **Gear Heads on the other site, Thought that the problem would be Just that, cruise and the 6 gear light. The Cruise wouldn't work correctly nor the 6 gear Light would come on..
Geezer Doesn't have Cruise on either of His 2 09 softtails so the only Issue on His would be the light... **Others, thought his TTS or what ever he already has would Also send the proper siginal or be
set up to send the proper signal so the Light would respond as Normal... Maybe Geezer will respond here also....
Heck of a GOOD Idea that Geezer has and is Working on the Change-out Right Now and IS replacing with a
Larger clutch basket gear to Make His ratio so he Can use 6th gear for Pleasure,,,, Not breaking the Speed Law to do so..
The 340RPM + or so Increase in Engine speed THRU-Out the gearing won't affect the Many other problems you get Like other ways of changing gearing ratios ::: From tranny = $$Belt $$sproket change and/or Rear wheel $$sprocket change then RE calb. Spedo with $$conversion box..
(his can be changed back by removing the primary cover, clutch and put on his Old stock chain and gear back on)
Geezer mentioned to me IF the only Nonworking is the 6 speed Light No Problem thingking he could Live with that.. HE/WE are ANXIOUS to hear a report when he gets it together and Tested out On the FROZEN road..
Just My thoughts here.. Hope Geezer didn't mind.
