2014 FLHTKSE and ThunderMax
The bike is basically stock (bought used with 1262 miles - assuming stock). I added Fuelmoto headpipe (Jackpot Super Duals & Crossover), and ThunderMax, stock mufflers. Terrible starting issues since ThunderMax install, but usually only first start of the day. After fighting to get it started it runs pretty well. Have done all the suggested things - new battery, clean / dielectric grease connectors (throttle body), adjust both initial and cranking fuel, even loaded modified map from ThunderMax support. Now have experienced limp mode since install of modified map.
The question is, has anyone successfully ran this setup or similar with ThunderMax? Do I have a faulty module or have they just not been able to get it right with the Rushmore's?

i ran a thundermax on my 120R briefly after install.
hard start was a routine occurrance. had zippers work on it for a couple hours in daytona.
it improved but was never perfect.
put stock ecm back on and went with PV and dyno tune
1000% improvement.
my experience. sold Tmax, never had another

I had a Powervison with a tune done by a vendor the bike ran good but always ran hot. Living in Florida didn't help things especially in the summer.
Installed a Thundermax the bike starts easy runs cooler never ran better.
Both are good systems I just prefer the wide band of the Thundermax my preference.
Make sure the vacuum plug is not missing on the throttle body.
I heard the Thundermax was dependent on good battery voltage but you said you got a new battery.

Thanks.
I ran a ThunderMax on my '10 LTD, no issues. I went this direction because I also like the built in autotune. (wide band sensors) I shipped it back to Thunder Heart today for evaluation. Hopefully they determine I got a lemon and replace it. Including the cost of the new battery (which I don't think I needed) I'm in close to a grand. Hard pill to swallow.

Been running a TMax on my softail for years. Probably 80k miles. During that time had 2 failures, both IAC driver. Both failures occurred immediately after washing the bike. Stopped starting it after washing it and haven't had a problem since.
IAC driver failure will cause the bike to idle very poorly, if at all. Get the RPMs up and it runs fine. Both failures were covered under TMax warranty.
