Last year I purchased my 02 1800C with the FI2000 and Cobra slashcuts already installed. Recently I decided to replace the pipes with the stock exhaust while I contemplate what direction to go with my rebuild. Before the switch, my low fuel light always came on around 90 miles and I would get the occasional decel popping. Since switching the pipes, I now get about 10-15 more miles before I see the light and I haven't experienced any popping. The latter may be due to new washers and making sure the acorn nuts were torqued.

My question: What are the benefits/downsides to removing the fuel processor and going back to stock? I also must admit that I haven't even checked to see if the desmog has been done. :oops:

Thanks in advance for your feedback.

If you just change all the pot settings to 0's, it should be the same as removing the unit. That will save you a bit of labor, and it'll still be there in case you decide to change the exhaust and/or intake in the future.

Even on a bone stock bike the processor with improve off idle response and shouldn't cost u any gas mileage. 2-0-0 is the way 2 go :) :) 8)

Nivek 66,
Is 2 - 0 - 0 a good setting with after market pipes as well?? (cobra speedsters) Also, the lower the setting, the less the fuel, right????
THANKS.

cobra 2000

I've got my 1st pot set between 1.25 and 1.5 running roadhouse slipons on an 02 R 1800 and decel is minimal---yes re settings, the lower the setting the less gas is metered in---my middle & third pots are set at 0

2-0-0 should work with any mods u make. And yes the lower the setting the less fuel. 2 on the first pot just fixes the lean low end and the ECU will take care of the rest.

Hey folks...new to the group! Glad to be here and riding a VTX 1800!

The settings you've arrived at...how did you come to them?
Have you dyno'd the bike with the Fi2000R set on 2 0 0 or less?
I've been told by many, even Honda dealer, that the Fi won't compensate
THAT much, and I don't have the Cali model with O2 sensors. So, how
did you find that Cobra's setting was too rich? I've run a few settings, and
each has felt the same power-wise, but my gas mileage has been pretty
good even with Cobra's setting, but did notice the end caps getting a bit
dark rather quickly. I've heard it's tough to judge the plugs too because
fuels now run so clean.

Just trying to figure out the best setting. I've got Speedster Longs too, and
Desmogged with a K&N filter.

I agree, however, I have always heardand felt it is MUCH better to be running a scooter a tad on the rich side vs. the lean, so I keep mine cranked up ever so slightly...I can also "control" the decel popping by maintaining ever do slight pressure on the throttle when I want it...you see,we have a LOT of deer in NW GA!!!!! JMHO.

Don't believe everything a dealer tells you.

Actually, I don't believe much of anything the dealer tells me.
What I do know is, I went for a little spinneroo around the block
with the pipes on before I put the Fi unit on, and it felt very leaned out.
So...has anyone dyno'd their 1800 with the 2 0 0 setting? What were
the results?

I'll add that the dealer that I bought my bike from gave me a good
deal on mine. BUT, the service department will likely never get my bike
for service unless it's an emergency. I had a "talk" with them about
installing Progressive fork springs and they insist on charging me about
$250 and taking apart the entire front end. Instead, I went on Biglry's
site, and will do it myself and ordered the spring tool!

I bought my 2-port FI-2000 from a friend that had 02 model it was set @ 4:15 & 4:00 and that bike ran strong, mpg mid 30's . i put it on my 03 model an the darn thing would not stay running, it was spitting rall fuel out the back of the pipes. so i backed off eack a little so it would run with out stalling. my mpg droped from 34/36 mpg to 23mpg wow!!! so i called cobra, I forget his name but he said that he new the unit well. I informed him I had an older 2-port fi-2000 his reply was the 3-port was made for the harleys because they run lean in midrang. as stated above the vtx does not need port 2&3 or in my case port 2. so he told me to turn port 2 OFF. then he told me how to adjust port 1. here's how it went, bearly crack throttle (with port 1 turned off I think @ 1:00 is off) adjust till you hear your motor get fat (deeper sounding) then turn it back till it leans out, then turn it back till it sounds fat again then back off just a tab. that did it for me!!! about 2:15 port 1. mpg went back up 32/33 thats about as good as it gets with the fi2000. because that's what the fi2000 does add fuel over stock!!!!!!!!!!!!!!!!!! my experience anyway hermultra

personally played with whatever name it has this year but TFI is who makes it. and it is a POS.
Why spend money on something you add fuel only and the all you do is add it down low.
Look at it this way................
you spend good money on a nice bike then more money getting the pipes airkit and acc to make it look and sound good then you penny pinch on the most important thing :roll:

Johnnycheese, I respect your knowledge and experience in this area. I can't speak for anyone else, but all I needed and wanted was to bump up the fuel at the very low end. The bike was running great everywhere except at throttle-up off idle. So for me, I couldn't see spending the extra $$$ for something that would require a whole lot more fiddling -- and probably more $$$ for somebody else to map it correctly -- to accomplish a minor change.

I'm not one of those who likes to do a lot of tinkering. A little tinkering, maybe; but whenever I think of a PCIII, I think of the same headaches I went through with the 1300 trying to get the carb jets and settings just right. Different process, I know ... but the same headaches. So I took a shot that the simpler FI2000 would do what I needed, and it did.

I'm just sharing my experience with the unit. But I'll also be the first to steer someone towards a PCIII if fine-tuning the mixture from bottom to top is what they appear to be after, because in that case, you are indeed correct that the FI2000 (and all the other names it goes by) will fall short.
