i have just bought my second R and it has the avcr fitted alonside the air/fuel computer. i must admit i havnt the foggiest how to use the fecker!
but i have been told that they are very good units, but you need to set them up on the rollers to get the best results,
Could anyone recomend a good tuner that can deal with these? im down in portsmouth but i dont mind travelling to a tuner that has a good reputation.
or the other option was to sell the two units and go for the apexi power fc or something along those lines!
