Breakout Stage 1 questions
I bought my 2014 fxsb last year from my local Harley dealer.
I was told it had a stage 1 upgrade,I could see it had Vance and Hines slip ons fitted and also the dealer gave me the SEPST box.
So yesterday I was having a look at my bike and stripped off the air filter and noticed it is the standard air filter (not stage 1 upgraded)
I have ordered a performance machine cone filter for it.
My question is, should I buy the SEPST cables and re tune the bike? It's more than likely the dealer has re tuned the bike to stage 1 as it came with the SEPST?
What at would you do ?
Im pretty confident of being able to re flash and record my data by means of recording a test run etx? But is it worth spending money on the cables?
The bike seems to run fine just now,I haven't fitted the new filter yet.

I assume the dealer has already re flashed it with a stage 1 otherwise it wouldn't have come with the SEPST?

But it's not stage 1 with a stock a/c, so why would they do that??? I also don't think it would be running fine on a stage 1 map with a stock a/c....but I guess you can try it first and see what you think, then decide.....I think you'll be re-tuning!!

By retuning, you will allow the engine to run cooler so the engine oil and exhaust won't get as hot.

i get what you mean but why would the previous owner buy a SEPST and not use it? Seems unlikely?

The dealer may have flashed the ECM with a Stage I map but the map will still have the bike running lean since the dealer must adhere to EPA guidelines. When you add a true stage I A/C, your bike will run even more lean by allowing more air in and not more fuel. You will need a new map to enrich the air/fuel ratio (AFR).
By retuning, you will allow the engine to run cooler so the engine oil and exhaust won't get as hot.

If I remember there are two types of SE tuners a pro and a street. The street tuners only allow for a limited map.. The pro I wonder if HD still sells them? Either Way a dealer is only going to give you a caned bs map. If you have a true pro tuner then get the bike on a dyno for a true stage 1. Or just buy a FP3 tuner since you have V&H pipes the map will be perfect...
I have the FP3 and on my softail I had V&H slipons and the map was spot on! A year later I went with V&H true duals and used the FP3 to reflash again.. Once again very happy with how the bike runs....Just my 2cts swifty

Let me get you started: SEPST User Manual
Welcome to the forum from central Texas, USA, Fraser. Congrats on your new BO. Ride safe and keep the rubber side down.
