I am almost done finishing my 81 olds. Im at the point of adding final details and gadgets. i have a couple hundred dollars layin around burning a hole in my pocket. I thought about maybe a wide band air fuel guage kit. its got a mild built 403 with and edelbrock carb just thought it might be cool for tuning purposes. Anybody have one do they really help at all with tuning? Any other ideas?

 

I have the Inovate LM-1, it has helped to tune my Q-Jet.

 

I too have a LM-1 . This tool is something I think everyone should have when tuning a car . I have had mine for 7 years . I have tuned all kinds of things with it . Everything from lawn mowers to a recent 1964 Galaxy 428 4 spd car with new Edelbrock heads . This tool can also log the data for you if you need it . It really beats doing the old "read the plugs" method :-) .

 

Thanks guys, anyone have experience with the aem one?
