Very informative post, thank you for the information.

Does anyone have any MPG data from before and after the SERF installation? Since it is a "fuel adder", I am wondering what happens to fuel mileage.

Default 883 needs Help With SERF

I hope this information will be helpful. If you decide to be the first 883 owner on the forum to use the SERF, let me know if I can help. I would think the 883 would respond well to Stage 1 upgrades (or a 1200 kit w/upgrades). One nice thing about the SERF is that it can be adjusted as you do upgrades. Stage 1 (exhuast/intake), cam and ignition changes, 883-1200 conversion,etc...

As a note, the SERF costs $224 from the dealer, or $179 from the dealers who offer 20% off. This makes it comparable in cost to what many dealers charge for a remap.
I'd really like to take you up with the help offer

I just did a thread/post explaining my problem.
Thanks.

Default Is This Thread Dead??? I Ask For Help Please.

????

My SERF is nothing like what you describe! Yellow light stays on all the time. Green light on at Idle. Red light only comes on when I wind her wide open.

According to HD instructions, #1 pot is #3 in HD instruction diagram. This pot is below the green light.
I therefore disagree with your pot orientation settings at the beginning of this thread.
If the unit is held in your hand properly, pot4 is above the green LED and pot1 is below the green. Pot 5 is above the yellow LED with pot2 below the yellow LED. Pot6 is above the red LED and pot3 is below red LED.
Looking at the direction sheet that comes with the unit, don't you agree???

Your info is backwards... or is the SERF unit's info backwards???

Default fuel injection is confusing

this serf sounds intersting. i to was looking at a rev tech dfo. then i heard about the s&s ezfi. after talking to them and some other people i have found that with a closed loop system that your ecm will undo everything that has been done and revert back to 14.6 afr. i have installed d&d xhp power pipes and an arlen ness super sucker and the remap. it runs good but has a slight hesitation off the bottom. i was wondering if this serf would have the same problem or if someone could explain this better to me. thanks guys

Did you get this resolved? I have a SERF that I just installed and am getting ready to tune this W/E. My HD documentation agreed with Mr. Harrison's description but HD's numbers all three fuel pots as #1 in their diagram. I will check against the information in your post tonight.

If you can provide your settings on all the pots and how you like it that would be helpful for me since I am tuning an 883 with the SE 50 state exhaust and Kuryakyn intake.

The SERF installed very easily, there is plenty of room in the valley between the rocker boxes and the bottom of the tank on the 883L to connect the wiring harness to the injectors. Since there is much confusion on the pots, I will give my settings as % of over what the ECM deklivers and the RPM bands so follow the directions that come with your SERF. This is on an 883 with SE (50 state) slip ons and a Kuryakyn Corsair open element A/C.

Low range fuel: +2.5%
Mid range fuel: +7.5%
High range fuel +10.0 %
low-mid cutover 1960 RPM
mid-high cutover 4500 RPM
Accellerator enrichment +50%

Note: the bike ran well before stage 1, and in a quick ride after warming up I have found no reason to go back and change these initial settings. A long ride is being planned for the w/e so any 'learning' by the ECM should occur then. If I make any further adjustments I will post them, but I will try to find a dyno day nearby to get some data. I am not that interested in peak HP numbers, I just want to check the torque curve to see if there are any dips that could possibly be tuned out by playing with the SERF's RPM bands and fuel settings. Since the slip ons are in the 'mild' range, I am not expecting to find anything major on the dyno. However, the A/F ratio at various cruise settings would be interesting to see and correlate with mpg before and after stage 1 with SERF.
