Its a very lowly cityrover.
I'm not concerned with milage and I suggest you stay clear of that sort of thing.
Never heard of the toolstick, mine is just a elm327 and a 16f628 programmed, nothing else, I probably wouldnt have done it any other way.
Access to the egr system and the emmision control is kinda usefull.
Interestingly I found and rectified a couple of minor faults on my car since I got this to work, the short and long term fuel trim are kinda usefull for that, esp when you do things like disconnect an injector one at a time and see what effect it has on the trims, you can test the injectors within a % this way.
Absolutely no info is available for my car, the only thing I know is that its similarish to a pug TU engine.
