EFI tuning question
I installed a SE HI flow air filter on my 2009 RK Classic and I am keeping the stock exhaust. I am condisering adding a PCV from fuel moto but I am wondering if I even need to spend the $300.00 or not. I am basically looking to reduce the heat from the engine and improve performance but since I have the stock exhaust is it even worth it? Also can I have my Harley dealer remap my existing EFI module and get the same results?

I put the SE stage 1 air cleaner on my '09 at 1k and had the dealer remap it. The remap was a waste of money. Six months later I bought the PC-V w/autotune from FuelMoto. BIG DIFFERENCE! Go for it.

You will need something to give the engine more fuel to compensate for the added air flow. PCV will provide a relatively inexpensive means of doing this plus it will provide options if you make any changes later. Get it from FuelMoto great prices and support.

with just a/c you don't need to tune from a reliability standpoint. If you want cooler temps, you need to throw fuel at it and a dealer download won't do that (they still have to meet EPA). So, in answer to your question, if you want cooler running temps, you need a tuner (and your mileage will suffer some).

If your like the rest of us go get the PCV cause you'll always be looking for more out of it, I would though do the pipes then let Jamie or Kieth know what you have so the can program it and its just plug and play then.

I put a stage one SE intake on my 07 ultra and a set of SE 4" slip on's. Bike ran fine. I read somewhere that the leaning effect of the stage I and SE 4" was insignificant. I also read that re-locating your engine head temp sensor if done correctly could richen the fuel mixture. I examined the sensor and found it to be very simular to the sensor in my camaro....basically...the mass of the heat sensor is in the tip. So I put a thick lock washer inbetween the sensor and head. which leaves a 3/16th air gap between the sensor tip and the cylinder head.
