Celica Forums General Discussion Exterior ecu

does anyone know if toyota can find out my rpm and mph when i bring my car to the dealer if they check my ecu? plz reply asap

in relation to what ? ...I don't think our cars have that black box feature. not sure though

I think that they can, but not sure that they would bother to. Why are you taking it in? I mean if you blew up your motor (this is assuming they CAN do it) then they might. But if you're just having your oil changed or something they prolly won't

yes it stores the info. If youa retaking it in for a misshift they can tell exactly how fast you whree goin adn how high the rpm went. If you are taking it in fo rhat reason then unplug your negative battery terminal for about 15 minutes and then plug it back in SHOULD reset your ecu, thus erasign your info.
