"Mongo no leave ...Mongo like Sherriff " One of my very Fav movies ...anyway I got into this discussion WAAAY late , I am now looking at a so called " Wideband " setup I read alot of this , but what is a " JAW " I hate that cliche " and abbreviations , any way I went to 14point 7 and it says url not found , I percieve it has been a long time and things have changed , Perhaps you would be so kind as to suggest a current decent priced setup wideband , gauge etc for my 91 740 turbo volvo , so far Im looking at the Innovative MX - L as per suggestion of Mike Brown lostart Mike... Im not too hip on some of this but it also seems a data logger is kind of a no brainer ...your reply is greatly appreciated BennyG Ben
