I have all the IGF signals faked now and I am looking at it on a scope for the first time.
They look great!!

One thing I am disappointed in, is some Toyota literature says the IGT signal is always the same. Well, it's not. At idle it is about 3.3ms. When you rev it up, the IGT signal shortens about 1ms.
