Forscan Dedicated Forum

[Betarocker]

You can change easily up to 35" ish diameter. Couple clicks and write. Then you'll need to sync the transmission to match. Larger diameter requires changing the Hex value. I haven't done it yet as I only recently re-found the spread sheet that has the converter from metric tire size to hex code.

In for this discussion. I need to adjust the speedo on my RV. I already have Forscan and got a cheap tablet to run it. Only hooked it up and used it one time and didnt know how to do much.

I don't know if there is enough interest to have its own dedicated forum. Perhaps a sticky thread under the Ford section?

Anyone have any experience with Forscan Lite for iOS? It’s available for use with my OBDPlus MX+ reader but I’m not clear what additional functionality it provides.

Forscan Lite allows for code pulling and some basic diag tests. You cant make programming changes with it. But its much better than most basic phone apps

Can you still get Forscan? I thought the sanctions on Russia were causing issues with it?

Its available again

Have you tried the MX+, how does it compare?

I'd love to find an expert here in LA, I have x4 warnings that come on every time I turn on the ignition for things I've removed from the truck, it's such a pain having to 'ok' them every time!

You should consider purchasing one of the units, they are cheap. Hopefully someone on this forum can walk you through disabling all the warnings. It comes with a free 2 month subscription which is plenty of time to do what you need, though the signup process is clumsy, it does work.

Is it OSX / Mac compatible?

For the 2021+ E Series, I have made tire size adjustments in the BdyCM module in Forscan's "plain English" mode. For the dually, the stock tire size circumference appears to be 2261mm (08D5 hex) (which I believe is 96.75% of a nominal 225/75-16 tire). For the single wheel models, the stock tire size circumference appears to be 2352mm (0930 hex) (96.75% of a nominal 245/75-16 tire size). For 235/85-16 tires, the 96.75% of nominal calculation yields a figure of 2448mm (0990 hex). I found that dialing that back to 2400+/-mm yielded the most accurate result based on my GPS testing, but I assume there will be individual variances based on tire mfr, wear and possibly axle ratio. Notably, I found that any change to tire size in the BdyCM--even to one of the other two "factory" tire size settings--caused the PCM to generate a P160A DTC code (invalid modification to BdyCM module). I found that code could be cleared by using Forscan's PCM "initialize and relearn BCM data" function. The DTC otherwise could not be cleared by performing the old-school "battery disconnect/drain the capacitors" PCM reset--I had to use Forscan's tool to get it to clear. Once cleared however, the P160A DTC has not returned and the speedo/odo have remained spot-on. Don't know anything about older E series programming - the above relates only to the 2021+, as far as I know. The subject vehicle for the above example was a 2022 E450 dually.
