FI2000 Tuner

[Philster07]

I'm wondering if anyone has experienced any problems with this unit on their fuel injected Harleys. My check engine light came on and gave me a ECM failure code. However if the ECM failed the bike would not run at all. It was only firing on 1 cyl and sounded like a loud Vespa! My dealer informed me that the FI2000 was defective and needed to be replaced at quite a cost. I decided to remove the FI2000, which consisted of unplugging the 2 O2 sensors, the crank trigger, the 2 fuel injectors and ground wire. I found the wires to the rear fuel injector was broken. So I repaired it and the bike ran great! So now i need to reset the codes and see what happens. So check all the wiring before you replace this expensive unit!!

I have the orginal FI2000 Tuner on my 05 EGS. I also have the Screaming Eagle Stage 1, and Screaming Eagle Mufflers. Bike runs great. I have 87K on this bike now. I am look at the auto tuner. Not sure if I will get it or not, but I am very satisfied with the Cobra FI2000 Tuner.

I have the Cobra Auto tuner on my 2011 FB Lo, I absolutely think its the cats (EDIT) . Bike runs great, no more popping on accel/decel AND if I want to change anything out in the future it will adjust to the change. Also works great when I am hammering it or just putting along over a hill or whatever, also adjusts if I have a passenger or not(never adjusted for that yet, my Ole Lady don't ride..YET..lol) Hopefully it stands the test of time.
Currently have Ness Big Sucker & V&H twin slash Slipons with Big city Thunder quiet baffles.
Happy Holidays!!

I have the Cobra FI2000R Auto tune on my 01 Ultra with the MM injection. Works great with the Ness Big Sucker Stage 1 and the Cobra 4" slip-ons with the S&S 510G cams. average 40mph 2-up and 42 solo. Will be doing a 97" BB with TW-5G cam upgrade with Screamin Eagle Stage II heads that have been shaved .060 and ported and polished so will see how well it adjusts to the upgrades.

I have been wanting one of these but I am not sure if I will be going with it, however the auto tune is nice.
