Yeh, its nice to see both AFR's on the logging software. They are very near exactly the same. Except for idle. That is a different story. Alot of reversion in that range.

Yep I see it big time on my combo. I was thinking of getting a set of Super Traps to try instead of the Ovals I know with my cam and my pipes it is huge. Unfortunately I don't think I can do much about it unless I go 2-1, try the SuperTrapp slip ons, but FIRST I want my duel TB, may go up in the injectors as you did. I know "everyone" says you don't need a bigger TB, larger injectors, but On my Sporty 1200 with SE pistons, mild port, and N2 cams, Dakota Kids bore on that carb was night and day. I am going in steps, TB with stock Injectors and see from there. There is just something about twin 50MM butterflies that just trips my trigger.
My bike runs very different with the PC III on and I find that odd. I am not sure better, but for sure different. I hope this is not some form of ECU degradation from emulating the stock ECU. They have too have something emulating the stock system, the stock ECU I think would be proprietary information.
I wish I could afford to have it tuned with the PC on, and then CONVINCE a certain guy from the North of me to tune the TCFI or do both for me. I would gladly run the 8 hours on it to have it tunned right.
I know it is my inability to operate and comprehend all of the TCFI but I do end up with pretty good fuel lines at WOT and Cruise, I just know the Timing needs set, and the then fuel again, and there is only ONE person I don't know, that can do it.
Anyway the TCFI is cool and you can get your fuel to anywhere you want it, but on the timing it is the starting slope I have know clue about. I mean the 95 setup file is canned and you said set for 10.5 but what about individual cam characteristics, and pipe combo? See that is my issue I have know Idea. Now I can induce ping and then pull it out with either fuel or advance but which to do, at what TPS/RPM position for best performance, is purely trial and error on my part. I guess I could go out and concentrate on each RPM and TPS after marking the throttle, and keep running up the advance and to induce ping and then pull it back, but there really is no piratical way to do that on the street. And even then, so it pings in 2nd gear at 2400 rpm but not in first at 2400 rpm, what to do, add fuel or pull timing.
This TCFI, and doing my build, loose comp nut at 4200 to coincide with the new build, exploding the rocker support plate, installing and removing a GP left side Support, 3.37 gear install, a fiasco and nightmare with an after market cam plate and pump (installed a cam plate and pump 3 times in 4 weeks) that I will never mention or write about again, and now moving to the Race Tech Front End next weekend I can say I know my bike pretty well mechanically, but still can not grasp the Black Art of tunning.
This forum, and it's members are the ONLY reliable source of information in one place, PERIOD, glad to see this sticky, because I need all the tunning help I can get.
