From my experience and what other's have shared of their experiences, you can read until you're blue in the face about how to tune EFI, but it won't make much sense until you actually hit the keys on a keyboard and see the results in real time. I'm not saying not to read up on tuning, what I am saying is don't worry if you don't seem to be grasping the concepts, because they are, for the most part very abstract, until you put them into practice. When I first got into tuning I put off actually touching a car for probably two years, re-reading material and reading new material, because I felt that I needed to understand the concepts better, but then I decided to just try it and then almost like a switch much of what I read made sense. That being said, close to 20 years later, I'm still learning new techniques, and ideas, as technology and understanding (including my own) advances.
As an update, I started the car I mentioned previously a couple days ago, after a month of not starting, with a starting temp of 52*F (11*C), it started with no help (no manipulation of the throttle), and while I do need to work on the immediate after start fueling it didn't stall, and ran well, again, this car has ITBs, no IAC (Idle Air control) that would help with cold starting, an aggressive cam. While not impossible with carbs, would be difficult and would require use of chokes and generally rich fueling. I still need to talk with the owner to see if he is ok with me posting a video, or if he wants to wait until he can unveil it properly. Maybe I'll look into some video editing to blur out certain things. lol
It is possible we met at Zcon, I was at the track day at Mosport. I wasn't able to attend any of the other events going on that year unfortunately, due to other commitments I had. I went with Jerry Barvinek in his car since mine was down waiting on some parts and time. He has a yellow '71 with white stripes that we had just finished installing an ECUMasters EMU on a week or so before and had a fairly quickly done street tune.
Also, I really like those Celicas, If I had thought I could find one of those easily back when I bought my 240Z, I might be a Toyota owner not a Datsun owner right now. lol
