Hi All!

I recently picked up an '05 Dyna Super Glide EFI FXDXI, and managed to keep from tinkering with it for a few months. However, I can't take it anymore - I'm interested in upgrading to a performance air intake and possibly an EFI tuner.

I'm interested in hearing if anyone has a specific performance intake recommendations, and also would like to know if anyone has a specific EFI tuner they would recommend.

I've rebuilt a few carburetors (Mikunis) and am familiar with the mechanical process of supplying the engine with the proper fuel air mixture, but have never gotten involved in fuel injection. Any advice would be appreciated!

 

 

 

I really like the PowerVision. I high recommend FuelMoto, they have excellent service.

 

I decided to run with a K&N Aircharger intake (dug the look), and the Dynoget PowerVision PV-1 to start. Having the ability to create custom EFI maps, adjust on the fly, upgrade to autotune, and data log (I'm an engineer, and the ability to data log and analyze that data is about like crack to guys like me) ended up selling me on the product. Should have these products Monday or Tuesday, and am anxious to see what kind of difference they make to my bone stock set-up.

Thanks for all the help everyone who responded!

 

My bike came with a SERT but after a few engine upgrades I just went to the Thunder Max ECM. Complete ECM replacement, no need to retune every time you upgrade, it tunes itself with wideband O2 sensors.

 

Here's what I did to my 05 FXDLI, there are no O2 sensors to deal with and control the ECM. I don't plan on any internal upgrades , so I installed A DFO (digital fuel optimizer), it plugs into the injectors and injector plugs into those plugs. It has 4 adjustable potentiometers, check Techlusion. This unit will help bring down the heat off the engine by making the mixtures as rich as you want.

 

If you're only doing stage1, you don't need much of a tuner. If you plan to go further in a year to two, then def get a better tuner. If you plan to do all kinds of things at different times, get an auto-tuner. Many to choose from.

 

This is true, sort of. I had a FuelMoto Micro EFI on my XL1200 and it definitely solved my problems running lean, but I'm pretty sure it was running richer than needed afterward. I had FuelMoto adjust the maps a couple times, but it was a bit of guesswork. When I got the Dyna I was planning to get a PowerVision, but the Dyna already had a TTS MasterTune. This wouldn't have been something I'd purchase if given the choice, but it is very powerful. I get a couple more MPG now with the Dyna that I got with the Sporty.

So I'm just saying even if you're only doing stage 1, if you think you'll have the bike for a while, it might be worth getting a more advanced tuner.

 

lol.. is that similar to being sorta pregnant? I think you'll find it is true if your honest with yourself. The length of time you have a bike at Stage 1 does not dictate how expensive a tuner you should have. For a stage 1 setup, there's not much to compensate for.

As stated, if you plan to progress past stage1 to 2,3,4, insane... then, yes by all means buy a tuner that will take you to the end game. Also consider what tuner any local dyno shop is familiar with... that 'could' be a huge advantage.
