Has anybody had any luck using there systems with the Toyota's? Mine have an AFR instead of an O2 sensor. They look the same,but there not. I can't get my EFIE to work with these.I put in a lot of hours on this project, to find out that these systems won't work on my vehicles!! I did however find that a 3/8" flange spacer did make a difference. I tried from 1/8" to 1", 1/8th at a time. Hope this may help somebody!!
