I have just purchased a rinehart 2-1 exhaust and im also buying the screaming eagle ac kit. Would the SERF work well with the combination when i go to get it dynoed?
Thanks

 

Yes, and btw it's a SERT, Screaming Eagle Race Tuner. Good luck.

 

I was told there was 2 of them, a race tuner and a race fueler. The part number is 32173-07 in a hd catalog.

 

Well then I apologize, maybe you are right. Never heard of the fueler and what the difference may be?????????????????

 

The SERF is like rejetting the carbs, whereas the SERT remaps the ECI (thus changing timing, etc). Here is what Harley says:
The Screaming Eagle Race Fueler (SERF) allows you to tune the fuel flow on your EFI Sportster. The fueler can electronically add fuel in much the same manner as increasing jet size on a carbureted system. It allows for quick tuning for the addition of less restrictive, free flowing intake and exhaust systems. The Fueler offers bands of adjustment that take into account operating ranges, such as idle, acceleration and steady speed. The Fueler is a self-contained unit that requires no computer interface. Adjustments are made by setting fuel, RPM and accelerator pump potentiometers, with changes monitored on LED indicators. The compact unit is designed for plug-in installation, and the small size allows the Fueler to remain on the bike for convenient tuning.
