am very new to all things Harley so could some one tell me what a SE PRO SUPER TUNER KIT is and why it costs 939.45 plus gst ?

Thanks for that even if get it dont think I would know how to use it.

I dont think I need it the guy at the harley shop told me I need it if I changed my air kit, I just when in looking at new pipes because I still have the standard ones.

Hi Greg,

you mention the XiEDs in a few threads. I have looked into them and have only found literature that states they only work in the closed loop state. Can you please advise what you do to take care of the Open loop operation of the engine, given this is where the performance running occurs? Maybe I missed something in the literature somewhere?

Cheers

Hi Greg,

thanks for your response. not sure it was me back then that you were corresponding with, but then again, brain cells fade fast.

Our specific experience in the open loop ( and tested with Wide band 02 sensors) is that there is scope for improved performance over the stock ECM with the intake and exhaust opened up. The WOT needs more fuel and the accel can do with a bit more also. The question is how much and what is being done to the engine by not adding it, trmp? lean?etc....Just some Fuel for thought.....

As you say, more than one way to skin a cat......

Hi Greg,

I read your post above here and several other threads on the forum ( you like cut and paste huh? )

Unfortunately, it doesnt actually answer my question, as it confirms it only works in closed loop.. It does not address open loop. From memory, ( and by all means those with the infor at hand please correct me), the closed loop is not constrained by under 4000rpm and <50% throttle. It is more like 10-15% throttle, which is generally cruise type conditions. Scotty, do you have the actuals at hand?

good discussion...

Cheers

Mick
