I don't post allot but do linger and interact now and then. I have seen allot of posts with frustration and praises of the DTT TCFI 2 install and experience. But not allot of walk throughs of there experience with pictures and we all love pictures. I am sure it is out there, I just haven't run across them. So I will try a shot at it. I just recieved it today and is my first look at it, I will post pics of the packageing and it's contents. This may take a bit of time from start to finnish since I am remodeling a room and the weather is crap here in MN at the moment. But I will add as I go.
I ordered directly from there sitehttp://www.daytona-twintec.com/TCFI.htmlon 2-20-2007 and UPS tried to deliver yesterday 3-1-2007.
I whent with the DTT TCFI 2 since it is very open for me to mess with everything, we will see how that goes.

I have started to install the ECU and WEGO unit today. Though I only worked on it for 1.5 hours.

I started out removing the ECU, fuse tray part way. Just enough to get at the 2 bolts holding the ECU in place. Then found a lip on the bottom of the opening for the ECU that needed to be cut off for new ECU to fit. The new ECU is thicker then the OE unit. After this lip was cut out the ECU fit but the tolerance is too tight for the harness connector to fit. So I completely removed the caddy to modify it for fitment. Maybe I will get to modifying it tomorrow. They do mention that some mods may have to be done on the dyna line, It is a deffinate on a 2006 WG. So it is not a direct replacement fit. One will need a means to cut plastic.
There is also a bit of wiring to do though very easy to accomplish. The wiring connectors are numbered so it is a matter of adding the jump wire to the correct position in the ECU connector and the Diag connector. I ran the wire through the harness for a clean install. Two sensor wires in the ECU connector need to be removed and replaced with the wires they provide, they will connect to the WEGO unit. I recomend doing this all in one step or one will be opening the ECU connector twice. There instructions for the ECU and the WEGO O2 sensors are in 2 seperate packets so would be very easy to miss and have to go back in. Not a big deal but saves time.
Only thing I have left as far as hardware install is replace the O2 sensors, find a home and wire the WEGO and finnish the modifactions to the ECU hole for propper fitment. They say install times as 3 to 4 hours I am guessing I will be right around that when finnished. I will not be able to do a ride and tune for awhile though since we still have a few feet of snow here. But I will add here as I go.

Everything is installed now just need to hook the laptop up to it and calibrate. I will probably do this tomorrow but not in a huge hurry, still allot of snow here so ride and tune not possible for a bit. I havemaybe 3 hours time into this install.
So today I modified the ECU caddy for fitment. I went about it by cutting a small slot out of the bottom so the harness connector slides in. For some reason my picture is blurred but is still understandable. Removal of the O2 sensors whent slick with no issue, broke free and finger loosened out, this is not normally the case. Anyway the rear O2 sensor is very easy to get at by removing the battery tray which isa 2 minute job if that. One could also remove the exhaust but battery tray removal made other things easy as well. Grounding the Wego unit to factory grounds and running the wiring for the WEGO is all easy with battery tray out. I am putting the WEGO device in the small hole space under the seat, it tucks in there nicely.
I then calibrated the sensors to air and final installed them. Rear O2 wires tucked up between battery and ECU caddy and the front O2 wire I ran up the top frame tube under fuel tank. Everything hidden fairly well.

I will write later my experience getting it running and ridding experience. So far this has been a fairly easy install, only thing that wasn't smooth is the ECU caddy modifications needed.

What is the supposed benefit over this system and say a PC III usb?

Thank you for taking the time to do a write-up and post pictures.

 

Thanks for taking the time to show us what you are doing, keep us updated.

 

Thanks Alaska Bobber and RoadTrain.

Alaska Bobber,
There are two large differences between the TCFI 2 and the PCIII. First beeing the TCFI 2 is a ECU replacement where the PCIII piggy backs on the OE ECU. TCFI 2 can run open loop or closed loop the PCIII is only a Open loop operation. The closed loop of the TCFI uses wideband oxygen sensors that range roughly 10-1 to open air. So you can keep it in closed loop even in full open throttle running mixtures that are optimum power or optimum mileage or EPA friendly. There are allot of other differences too but I will be writing a book. DTT's website has allot of this info http://www.daytona-twintec.com/TCFI.html. There is another system very much like the DTT TCFI 2 which is the Thunder Max auto tune, Psycho just installed one on his bike and appears to be very happy with it.


I over slept today so most likely will not get to work on calibrating today.

 

Ah I did not realize that the TCFI would run closed loop. That is a HUGE difference than the PC III then. I have 200 miles on my PC III now and I like it a lot, but I am still curious how I will run at higher elevations.

 

Great information! [sm=thanx.gif]

Take notes guys! THIS is how you post! (hold on jotting down notes myself...)

Please keep us informed on your first impressions on this setup!
