This app is very, very close to bringing something to AC that i've personally been wanting for a *long* time. It works quite well on most automatic transmission cars, but has a tendency to be just a little bit too sensitive when giving it between 50 and 90 % throttle. I would totally co-sign on the review made earlier, suggesting some solutions to this "issue". However, i applaud the idea and the implementation. An update on this part, and you'll see 5 stars from me for sure. I'd also love to be able to donate a coffee / beer / whatever for your work on this one.
Cheers! :)
