Thanks for the nod, Jim. Of course, that's the whole point here, isn't it? I've saved a lot of time and trouble here as well. And remember guys, if your car is going into "limp home" mode on full acceleration, there is a problem. It isn't normal that it should kick in at all except by mechanical or electronic fault. If anyone can help me post that block diagram, let me know. I can scan it but if I attach it at permissible res, I don't think it will be readable.
