So here I am with another question which is unrelated to this past question, but I thought I'd just as well post in here instead of a new thread.
I was looking through some files for an OBS Auto(TDE1) so that I might find some convincing changes I could show someone who is interested in getting a chip for their truck. So I come across the inferred throttle position map and it doesn't seem right. ![]() Picture 1 is the stock file. Picture 2 and 3 are modified by myself to be what I think might be right. What came in the MDFs would be picture 2, except imagine "Area A" to look like picture 1. Maybe this is just another thing I'm worried about which doesn't matter, but nevertheless I got some enjoyment and experience "smoothing" a map from picture 1 to 3. After looking at other MDFs at the same map, if I had to guess which is right I would say either the way the file came or picture 2 as shown?

It's always looked that way for me.
I have never had a need to alter that map so I haven't cared. The one for the manual trucks doesn't look much better....kind of resembles a set of stairs. Sorry I don't have an answer for you though.

Ok, that's what I was looking for, just to be sure that what came was normal and I wasn't alone. So is actual throttle position used in calculations or does the computer use the values determined from this chart?

Don't quote me on this, but I believe that the Inferred Throttle Position map has to do with cruise control operation....The axis are kind of reversed from the normal MFD map and it makes sense to me how that would be the case. However, I can just about guarantee that your cruise control probably works just fine, right?
