interesting. with all the talk about the r16 i did a little test today. i have recently installed an A/F meter and have used it to tune the mixture a little. these 4 runs were made with the car up to operating temperature, on the same road in the same directions. what i did was made a run down and back on a local road with the r16 in, then one with it out, then in again, then out again. my A/F meter indicated more rich at WOT with the r16 out. now connecting and removing the r16 isn't likely to do anything to the engine's fuel delivery. likely, it does affect the conditions in the combustion chamber, leading to a more or less complete burn. so, what does it mean that with the r16 plugged in i'm getting a more lean exhaust, indicating a more complete burn with the same amount of fuel? anyone? i have an idea but someone out there has got to know more than i do about the subject.

thanks,
