I have an '03 XB9S, has a Latus muffler, K&N High Flow air filter and K&N catchcan with the open airbox conversion kit on it. Put the TFI on tonight, followed the instructions. Let the bike come to full warmed up temp, and started turning the green pot up as the instructions state. The RPM's never rose, and it almost sounded like it was flooding the bike. The Green Pot did flash when I turned the ignition on, and stayed on after the bike was started. The yellow POT flashed for about 3 seconds then went off. The instructions say that the yellow POT should flash for 15 seconds then go off? My question is: is there supposed to be an immediate RPM response as you turn the green POT up? I turned it up to about 4 o'clock and the bike seemed to gradually rise in RPM's, but not to 1800 RPM's like the instructions state. Any help would be appreciated. | ||

Hi.. You have got it a little wrong... Almost correct. Warm up the bike, net in neutral. Take a screwdriver and increase your IDLE RPM up to 1800... Then attempt the 1st pot. Add gas till she won't take any more... blah blah blah as per instructions.. Regards | ||
| Sweetp411 |
Ahh, so raise the RPM POT until 1800 RPM's then adjust the GREEN POT. One more question for you. In the instructions it says that if you have a blinking GREEN POT, that there is a bad connection between the TFI and the fuel injectors. But it doesn't state if that's a blinking light while it's running, or when you turn the key then the ignition and it's going thru it's electrical and fuel sequence? Because when I turn on the key, then the RED ignition to start the fuel pump and stuff going, the GREEN POT blinks and doesn't go off? The instructions say it should blink then go out but it doesn't? But it does stop blinking and stays on when I turn the bike on? I figure I have to have a good connection with the fuel injectors cuz the bike is running? Is this not right? If the fuel injectors were not connected right, or not at all to the TFI then the bike, the damn thing wouldn't be getting fuel and would run right? | ||
| Briz31 |
no no no... leave the TFI alone... Raise your bikes IDLE, (use a screwdriver) the idle screw which is located at the front of your bike (see manual) turn clockwise, it may be tight, your IDLE rpm will increase, once she's idling at 1800RPM then... and only them.. Fiddle with the TFI.. Cheers... | ||
| Sweetp411 |
ahh, gotcha, yea I know where the idle screw, damn those instructions were kind of goofy. any thoughts on the blinkin GREEN POT prior to cranking the engine over? leave it alone? I figure it's hooked up ok or no fuel to the engine, no runny runny  | ||

read the instructions again sweetp. As Briz says raise the idle to 1800 using the idle adjustment on the bike not the tfi, then with the idle at 1800 turn up the green pot to about 3 O' clock which should be about right. The green light will flash when the ignition is on, when you start the engine then the green light will stay lit. If it still flashes with the engine running then you have a bad connection. Try setting the pots to 3,3,3,8. That setting seems to be a good start point. 7 on pot two is too much and you may get surging. | ||

Sent you an email... | ||
| Sweetp411 |
also, as u can tell, I'm quite the novice at this, but do I leave the idle screw where it is @ 1800, or do I return it to normal idle speed after adjusting the TFI, sorry mate, I know I'm bein a pain in the arss | ||
| Sweetp411 |
I read the instructions, perhaps the instructions they send overseas are in better detail jk, I'll try those settings out Airbox, thanks again guys, u rock | ||
| Briz31 |
when in IDLE, the green on mine flashes... Hence the unit is not operating on idle. only when you apply the throttle does it come to life. (Then the flashing light goes out) The more throttle you give it, you can see the other pots flickering as they do their thing. | ||
| Briz31 |
After you have it set... (This is pot 1 only) all your others should be OFF. Once you have set pot 1, Lower you IDLE rpm back to the original position. Then set the rest... I'm using: 1. 3 2. 7 3. 4 4. 8:15 but going to increase pot 4 to 8:30 as my ECM is still trying to lean her out... trial and error process... | ||
| Sweetp411 |
Thanks Briz, that's a huge help. I had seen those settings that you just gave me prior on the techlusion website in the support forum, so was going to go with those if all else failed me. Thanks again, you need anything let me know, not that I'd be much help, but I do have a spare stock muffler, airbox cover, and handlebars now if you get in a bind | ||

briz, the green light should not flash on idle. It should stay on. If it flashes then you have a bad connection to one of the injectors, according to the instructions. Can't remember which one as I am at work but will have a look when I get home and post what it says. I tried the settings you are using ( they are the ones recommended ) and it surged ( like the brake was being applied on and off), so tried 3,3,3,8 as Rigga suggested and it ran fine. I think maybe you have not got it set right mate, especially if the green light is flashing with the engine running. | ||
| Briz31 |
Airbox... Your right... I got a little messed up... On power mine just flashes doesn't go out... Once engine is running on IDLE it's out... I ran this past George, some go out some don't. BUT on engine start they should go out. If it flashes on engine running... GREEN it's your front injector connection. Cheers guys, ride safe... | ||
| Briz31 |
Yeah... that's what I mean to say... GREEN ON... Engine running. FLASHING... BAD... Arrrrrrrrrrrrr TFI it's all crazy talk... | ||
| Rigga |
some engines will take fuel increase at idle so the green light may well be on as soon as the bike starts,some only start to take extra fuel once the revs are raised slightly,so the green light will illuminate then,it all depends on the particular bike,green led flashing with just ignition on and engine off is fine Briz how is the jardine insert panning out? anything worth reporting on your handiwork? | ||
| Airbox |
Too right Briz. The TFI is confusing. Especially the settings. George is too far ( expensive!!) for me to phone and his site is not that good on answering questions although he does eventually reply to emails !! | ||

Sweet - I assume you are using the stock ECM & not the race ECM. | ||
| Sweetp411 |
Yea, this is all on the stock ECM. The GREEN POT is staying lit when the bike is idling. I was also doing this inside my garage last night and it's not the best ventilated room in the house. Perhaps I need to take it outside and tune it, or just run it for awhile and tweek the settings? In the garage, I think the O2 sensor was getting bad readings, cuz I was coughin fumes myself. With the 3,7,4,8 settings, when I throttled on, it took a while for the engine to return to idle, like the throttle was hanging up, but the throttle was returned to idle, but engine still at higher RPM's. I think I just have some tuning to do. | ||

sweetp411, Turn your idle down a little bit at a time to get it to idle down properly. Just move it small amounts and try it. | ||
| Drift |
Sweetp411. I don't know if this will help you or not. I have an 05 city and just cut the airbox, installed a K and N, put on a special ops pipe and TFI. The standard TFI settings 3,7,4,7 ran my bike rich through the roof. So much so that I went down from 130miles per tank to 80 and you could smell gas when I parked. She was also dogging out on me on acceleration. Suffice to say that you may need to change your settings severely to get it right. Don't get tied to the "recommended settings". I will also tell you that I had heavy popping on deceleration and when I cut the airbox it cut that in half. | ||
| Jerseyguy |
Drift - I have done extensive testing on the 9 with race ECM and TFI. My conclusion is that I took the TFI off. | ||
| Hogs |
Jerseyguy, Correct me if i`m wrong but did you not find that with your race ecm on and the tfi that on pot 1 you had that on number 3 and pot 2 and 3 you had them off and pot 4 you had that set just so it fooled the ecm 7 - 8 and that with pot 1 set to 3 it worked okay.... As I was under the understanding that all these buells do run a little on the LEAN side down there and just setting pot 1 to 3 or 3:30 or even 4 will fix that spot??? | ||
| Jerseyguy |
Hogs - What you said is true. That lean part down low.... I'm not so sure any more. I've been looking over the mass of data I have and lambda generally is in the low to mid .9s in that 2k to 3.5k RPM range - a lot depends on throttle opening and whether you are accelerating or backing off. This is pretty close to the desired range of .85 to .9. Backing off is of course very lean at times like lambda = 2 even and that may pervert the average data on the spreadsheets. So is it worth it to dumb down the adaptive nature of the race ECM with pot 4 high at say 8? I'm thinking no at this point, but I'm not real firm on it. I am taking the TFI out though 'cause I still think the race alone is generally a little rich. If I do put it back it will be with the stock ECM. My frigging head is exploding with all these charts and I just need to get out and ride for a while. I still have to test Kevin's new Drummer yet too. | ||
| Hogs |
Jerseyguy, My frigging head is exploding with all these charts and I just need to get out and ride for a while. I agree with ya there 1000 PERCENT | ||

On my TFI, at idle (around below 1500 rpm), all three lights (green, yellow, red) flash in sequence. The flashing stops around above 1500 rpm. THAT IS NORMAL ACCORDING TO GEORGE at Techlusion. | ||
| Xbolt12 |
Dcmortalcoil is right. George said it's because the TFI is not adding fuel at idle. Hmmm, that would mean that the popping on deceleration is probably impossible to prevent with a Jardine.... |
