nah....auto time usually works off RPM. And i wasn't aiming that at you, was just saying in general like.

My mates actually got one in his Silvia (Jap version of a 200sx) and it seems to give a fairly accurate AFR.....but....its narrow band so its not really accurate enough.

And to summarise, if you have a category 1 alarm a seperate turbo timer is a useless piece of equipment anyway
