I am having technical issues with my DTT TCFI. it is stalling out in the bottom end and has started a decal pop. So I go back thru the istall procedure, checking the TPS V and the IAC, all checks out fine, I then begin to wonder if it might have to do with the O2 sensors not reading true so I go to preform a fre air calibration and I can not get the WEGO to do it's thing? When I turn the bike on the lights both flash on and off 2 or 3 times then quit, I can not get them to stay flashing. Has anyone ran into this before and is it the WEGO pooched? I am waiting to hear back from DTT on this but I am not holding my breath for any positive replies, I have tried to deal with them before.

Anyone with some hints would be great.

 

Nobody ever run into this before? It turns out that the DTT techs are both out of office today and I still can't get any help.

 

Craig ~ You'll really need to just just give them a call.

My $$ is on a bad O2 sensor. Rob (Hotpursuit) experienced this once and it was on a newer TCFI-III. Just give them a holler.

 

I had an issue where I was not getting any lights on my WEGO and I foundit was not getting any power. Check the fuse box and make sure everything is OK in there.

 

i did experience a bad 02 but it just gave false readings, letting thescoot run real rich, fouling plugs... sounds like somehow your not getting power to the wego... from what im understanding you cant even adjust your trim for the free air? power lost some how or maybe a fried wego...

 

i am sure there is power to the wego as the lights light up on ignition but they go out immediately and do not come back on, and I can not get any responce when i try a free air calibration. I called DTT this morning and am going to have to wait till tommorow, nobody is in the office today. I just uploaded an older map to give the bike a try and it seems to have fixed it for now, but I am sure once it works in the BLM it will go back to the way it was, I know by the plug reading that it is rich in the bottom end but good in the top, runs nice above 3000 rpm it's just that decel and the idel that really sucks right now

 

til you get an answer....turn off the autotune and load the good map

 

ok now that works for me, how do i go about that? just pull the power from the wego or isiti in the program someplace? I was tring to figure this out today?

 

go into the advanced parameters....its the first box on the left

 

perfect, I found it and thought that might be it. thanks
