spikes in maps

I actually asked about the inferred throttle map once before so I know exactly what your talking about there. Working with OBS auto? I haven't seen what your describing for the torque table map though. Usually you can tell what the axis units are if you view the numbers/spreadsheet view using F6. Here is where I asked about the inferred throttle once. I can't find the picture from my photobucket account so I just took another screenshot. Left is a stock, right was from a low HP tuned file for a stock truck. I think the right is the same for all tuned files.

I had looked at mine to try and see what you were seeing GTS, but mine looks nothing like what Thomas had posted.

That is odd.

Forgive me guys I'm not much of a computer wizard. Never really done much for screenshots so I'm not sure how to do that. But the graph Thomas posted is one that I am talking about. I'll try to figure out how to do a screenshot and post up the other graph in a bit.

OK I hope I did this right. If so the pic of the map should be below.

Wow, you OBS guys dont have much resolution on that map!

As for the shape, I could not tell ya.

That's not right.

Either the definition is corrupt or the binary is corrupt. If you PM me your email address, I will send a stock TDE1 binary to you to see if it's the problem or not.

Oh, and your inferred APP map is just going to be that way.

e-mail is gtsmotorsport@yahoo.com.

Thanks for the input. Do you have any explanation as to why the APP map is that way or is it just that it is what it is?

If I smooth out that dip is it going to affect the other maps so I'll need to go make adjustments elsewhere as well.

This brings up another question, If I make a change on one map that changes things on another map will those changes on the other map show up on the actual map. So if I move something on one map and have the other map that is affected as well pulled up side by side will I see the changes being made by the map I'm working on move things in the other affected map? Or are all the changes to the other map more or less behind the scenes

Dave can you please explain a bit what you mean by not much resolution? You mean the increments aren't as fine as in the SD files you have?

The spike in the middle of that map is obviously not supposed to be there. Hey, Ford's not perfect either.

As to the definite ridge in the middle of the map, this is because the X-Axis transfer function for the map only addresses the first 10 columns and disregards the rest. This is where transfer functions can get tricky. You can actually correct the transfer function to address the full scale of the map and provide greater resolution, but you just need to be really careful or you can cause all sorts of oddities. For the most part (on this map at least) there really isn't any advantage in expanding the resolution so there no reason to even bother.

The map in this example is not addressed correctly so the start of the map is shifted. This could be due to a problem with the binary file, the definition file, or a mismatched binary/definition combination. I see this when using a VDAB0 file with a VCAB0 definition, and vice-versa. If you could let me know what binary and definition file you're using, we can clear that up for you.

Take care.

Why do they make the entire map if they are only going to use the first 10 columns???

The Defenition file I'm using is VCAB0_02(216e).mdf and the Bianary I'm using is the one you wrote me when you live tuned my truck. VCAB0_02-Version2\0002_1_224K.bin.

I hope this helps figure out what's going on.
