Well, Armstrong, just re-read your post following what we talked about today. Even if it locks rpm, that's the same as speed because the two are related. Ie, if it locks it at 3000rpm and I'm in 6th gear, then, it'll also be locked to 110km/h (or around there somewhere). As speed increases, so would the RPM, thanks to the gear ratios and whatnot. But, *fingers crossed* it'll work like every other cruise control I've ever used :D. Ordered from www.toyotapartsales.com Can't wait :D <lazy> :P
