i recently bit the bullet and got another car, it's a 1995 opel vectra A GLS 16.i
got tipped they had this car coming in but i had to make a fast desision or otherwise it would be scrapped... silly regulations here, with the governement paying up to 1500? if you have you're old vehicle recycled when you buy a new one. new cars are supposed to be cleaner, but with only 27000km's on it, i'll recycle this vehicle myself.
i haven't driven it so i don't know what milage it will get, hopefully not to much worse than the kadett, but as it's an early injection model it's got more potential for feedback on FE than my carbed kadett. fe figgures on paper are about the same so i keep my finger crossed
it does however have some sort of odb port so i'm contemplating what i might hook up there. originally there was a primitive trip computer on the option list that could give instant feedback on FE, and trip fe etc... much like a scangauge does i believe.
so the car is capable of delivering some interesting information. question is what options do i have to tap into that?
findeing the original trip computer might be the easyest and cheapest way... but this was probably a rather rare and pricy option wich will be pretty difficult to stuble upon in working condition.
a scangauge seems a fine tool but a bit expensive and i'm not sure if it'll be fully compatible.
so how do i go about this? how could i find the protocol my car uses and what hardware could i buy/make to tap into this info?
any usefull links/tips?
i'm not affraight to try and build somehing myself, but i wouldn't like the airbag to go of on me or something like that
