GT350 FORScan Tweaks

[TonyJ5150]

This is great stuff. Much appreciated.
Once its figured out, maybe we can get a sticky with Turn by Turn directions of what we need and how to do some of the more common changes.....Thanks again!

So it turns out I was 100% correct. The second value of 720-06-01 does control the display of those two line items.

I learned in the process of tinkering with this that the last byte of the third value is the checksum for the address. I also discovered that a guy on the ForScan forum wrote a very handy tool for calculating checksums and comparing asbuilt files. Kudos to him for making this no-brainer work (though I did this by hand because I didn't know any better . http://forscan.org/forum/viewtopic.php?f=5&t=2012&start=10

So without further ado...

Address 720-06-01

No Axle or Trans Display    7F6D 0664 9E22
Axle Oil Display            7F6D 1664 9E32
Trans Oil Display           7F6D 8664 9EA2
Both Axle and Trans Display 7F6D 9664 9EB2

So us Tech guys CAN get the Trans and Diff temps to be displayed with this tool..correct?

Also, any way to keep the exhaust valve closed in the normal mode under WOT?

Awesome work!

Do us base owners have access to that same display for temps ?

Matt, interesting to see the guy in your link able to turn on an engine hour meter. Have you looked at that?

You're just changing variables that get used in the code. If there's not a variation between car trims/models/etc, then they probably haven't put in a variable to control it. So, probably not. You cannot make the car do anything you please by just messing with CAN module configurations.

The same code (basically) lives on all the cars. This is just tweaking a variable that shows and hides something.

I had not.

I did try messing with other possible bits in that value (the temp display toggle) though. Interestingly, even with the correct checksum, the car would not apply values that it knew to be invalid. So while trying to flip other bits on, it just said "invalid configuration". So that makes tinkering with these things pretty easy.

Thanks for finding this!

Just got my setup today. Forscan will error out when I select 2017 Model Year. It starts to load the modules then says "Error, contact developer" in both the Windows and Android apps. I changed it to MY2016 and it seems to be working now. Still trying to look at everything before touching anything.

Look to see if you can change the exhaust mode default

Yeah, I'm not sure what the deal is there except for that the program only supports some MY2017 vehicles at this point. Everything worked fine for me when selecting MY2016.

wondering if any of this will bleed over to the GT....

 

[swedensky]

Yes a step by step will be needed for some of us =) I look forward to spending money on this one!

Great find guys! I have my OBDlink MX on order

 

[montreal ponies]

Can my KIWI3 OBD reader do the same ?

Can my KIWI3 OBD reader do the same ?

Or even the OBDlink LX??
