In setting the tire size, I would try the shorter size first, drive by the radar again and see how close it is. If it is close, I would leave it. If it is off again try the taller size and see how close it gets you. Then go with the better of the two.

Well i got the tire size adjusted so im within 1mph of what the radar says im goining, so thats working fine now.

The one thing that I have noticed though after going through all of this and working out a few kinks here and there over the last week is that I am really not a fan of not being able to view the modifications I have made to the tune or tire size. If there is a way to view this information someone please let me know, right now though when I go in to view the programmer status it just says 91 Performance tune Modified (or something along those lines) but that is really my only complaint. Otherwise I have writen down every adjustment I have made thus far and have a notebook setup just for the tuner that has the full manual, a few links of the data logging instructions, and a few note pages.

Now that you got your speedo figured out you should probably go do your 0-60 runs again since the SC goes by your speedo and if that was off then your times would be off too.

It is kind of a pain that the DSP doesn't display what changes you have made without actually going into the tune modification screen. What I have been doing is saving my data logs and when I save them I include detailed notes about what parameters I changed and what they were changed to.

It got a sticky cuz it's a really popular thread that has been going for a while.

Even when I go back into the tune modification screen though (at least for the trans options) it shows the numbers for their tunes and not the ones that I set yet still leaves the star next to the option which means it was modified, it doesn't even retain the tire size numbers so I cant go back and check that out either. I mean I know that the changes were made because the shifts are much better than they were with just the performance tune installed, and the speedo is at least close now but still it gets a little annoying to not be able to do a quick check.

As for the times, Im one step a head of you. I went out after the speedo was working and re-ran it. first run was 6.15 second was 6.13 and the last was 6.10. Not as good as the 6.05 that I got the first time around but it is still an improvement over what it was.

One thing I am going to do either tonight or tomorrow night is go through all the menues and just write down where everything is located. I'll even go through the data log screans and write down what is under each one of the options just so there is a list to make things simplified when trying to find a specific screen or log item.

If you go onto the DS forum there is a menu map made by a member over there that shows all of the options for each screen. It is made for the u7135 but after looking at it the map seems to have almost every option the same as our tuners.

I've seen that one, however I want one that is just for the U7137 as it is missing some options that the U7135 has and I dont want any confusion on my part as to what it does and does not have, specially since Diablo doesn't even know what features it has as they had posted up that it had a shift firmness adjustments and a few other adjustments in the quick adjust menu and yet the only thing in there is a tire size adjustment.

OK, just wanted to make sure you saw that one before you made your own. When you get done post it up bc I for one would love to have a list of all the different menus for the 7137 .

Oh yeah, it'll be posted up for a reference for anyone else trying to find that one menu that they saw when they were first messing around with it but cant find it again...
