Yes, I agree that you shouldn't mess with your AFR without some sort of tester. That said, I used a Gunson before I got the LM1 and used that to set my AFR. I set the AFR at idle with the Gunson and IF your CIS is working correctly then when you set it at idle it'll be right on WOT. But after reading a lot of threads and asking lots of questions the LM1 seemed to be the product of choice. Ok, so I picked one up. After I checked the the CO with the Gunson I checked it with the LM1 and my AFR was right on. So with cost not being a factor, I would go with the LM1. But on a budget I wouldn't hesitate going with another Gunson.
