Hey Jim, as mentioned send me those logs and we'll check it out.
Your lean spike is because of your VE, it's all over the place and makes no sense as I mentioned to you yesterday. Normally it's not the ECM that's the problem but that's what almost always gets the blame.
As far as self tuning, the Accel makes doing it yourself much easier than most. You simply datalog it and drive it like you would anything else. Then come back and do a "Fuel Overlay" that will tell you where you just were on the VE tables. Take the cells and correct them accordingly, either individually or in groups. Normally takes less than an hour and you can customize your map as well for extra lean cruise etc, can't do that with the EZ stuff.
And don't forget the benefits of total spark control, and from cold to hot running. None of the self tuning stuff has that either.
