Hi,

In case I missed it. Do we have a thread what and how you can change or configure things in OBD Jscan?

I resently got the tool just to update the Liters for my fuel tank.

Thanks
Mike
 
There doesn’t seem to be any one master thread for jscan. If you search “everywhere” for jscan it comes up often in other threads but no 1 stop shop for all things jscan yet.
I also just got jscan for my 2023 power wagon, and only regret not getting it or sooner. So far I calibrated speed by changing tire size (do this on level ground as it often seems to require an abs initialize to fix the many error lights that come with changing tire size), changed TPMS set points, turned on gear indicator (requires setting to be turned on from dash after selecting “active” on jscan… I’m not proud of how many times I selected active before I did some digging and found it activates the dash setting to enable it to be turned on and doesn’t just turn it on automatically), and disabled fog lamp drop out (keeps fog lights on with high beams).
There’s so much more jscan can do but that was all within the first hour of having it.
It’s also important to note the need for the security gateway bypass cable on any 2018 and newer vehicle. I used the OBDLINK MX+ it’s the most expensive option but also seems to be the most full proof when it comes to working with whatever vehicle you plug it into. A license is needed for each VIN you want to make changes too.
Tank size was on there I do remember seeing it, just didn’t mess with. Should be easy to make the changes. The app has a really nice demo mode that lets you look at all the options, and the search feature works well if you look up “tank” it will bring up the setting you are looking for.

Still link to the 5th gen ram forum on Jscan. This is where I found a lot of my info from earlier. I know the HD trucks aren’t true 5th gen’s but a lot of the jscan stuff seems carry’s over and is the same or atleast very similar.

I routinely change my TPMS set points. JScan makes it easy with a great interface. Also recently recalibrated my dually’s rear air suspension. Great customer service as well. Can’t be beat for the price.

Are you accessing JScan customer service by any means besides Facebook?

I also saw there’s a setting for the TPMS percent of that point to turn on and off the light. You have to go into the modules and BCM tab. I haven’t tried to mess with it but if you need a wider range for TPMS that might help.

That would be cool to avoid having to switch pressure thresholds.

I got the tank size adjusted. Easy peasy.

Now I am looking to get rid of the 3xhorn when exiting the truck on running engine.
Anyone knows where to do it.

Is there a tutorial on how you did all of these? I got my bypass cable and vLinker MC+ from a fb member. I tried changing the tire size and tpms threshold but got a lot of errors. I reset all of my settings and got a lil discouraged.

Also, what vehicle did you select? I thought our trucks are DT body style but the only option were for the 1500s.

I have NOT done that, but I think it is ABSOLUTELY initiation or something like that

Your original post stated you calibrated the speed by changing tire size. I tried doing it but got warning lights on my dash and restored the settings.

Sorry I only meant the gear indicator and TPMS.
