Does it have limiters on min (1) and max (4)?
If it has limiters, then it's a little bit safer...
If it doesn't, then you can easily jump from min to max with one errant signal.

There has to be a reason why Mazda went with a feedback signal system.

You would think that the OMP system is important enough to have this feedback system functional.
It does throw a nasty error (which goes into limp-home mode) when triggered.

From my understanding, that's EXACTELY why the DBW systems have the safety of a redundant TPS in there... to prohibit thing like that from happening.

Also, from my understanding the OMP on the Renni doesn't have a feedback, while the S5+ units do, again, for that reason of it being rather important. Not quite sure why Mazda changed it for the Renni, but I'm sure they have some type of safety involved with it... I agree with ya, it would be foolish not to,
