Anybody that knows alfa wanna get me started? I sent my back up to Google, but I need to store my proxy settings, and maybe do the tire change to get familiar a little. I tried global windows down, and damn near broke the car.. Someone on FB said I can't do windows down with this model.. My success story with this software so far, is that my car still runs...

I only did very basic functions with mine. Did a proxi alignment, turned off fog light drop out w/ high beams, and turned off the DRL drop out with turn signals.

I played a little with the single actuator function. I haven't had the washers since I bought the car, so I have been trying to diagnose that. Alfa is quite a powerful tool. I did get the washers to shoot fluid with alfa, and I'm waiting on the new steering wheel switches to see of that's the issue. But, after the attempt at global windows down, I'm a little shook up.

Yes global windows down doesn't work. I believe its due to the module not being powered on when the key is off. The fog lights with the high beams is usually a go to and is easy. I was able to use alfa to get Off Road Pages briefly, but after about 30 minutes it asked me to log into my Uconnect (which I didn't subscribe to), and then it removed itself. There are also some updates I had to do to the radio that require downloading and installing one at a time. The other think that comes to mind with alfa was I was able to fix my rear parking brake. It locked up on me when I was replacing pads and wouldn't come out of service mode. I was able to move them independently to get them back in sync and then all was good.

You mentioned tire size. I have not tried yet, but do not thing that it is possible either. I've heard others had ABS issues. Not sure if its possible to track down and reprogram everything that is affected. I've just know I'm going to be about 4 to 5 mph off, and to add 1.4 mpg back to my mpg to know what I'm running.

I wish there was a pinned post for our model that listed what's possible, and the steps. The dodge truck has. Pretty decent footprint on YouTube. But, our little grocery getters are ignored. Maybe I'll try the lights. I heard it really helps mileage to do the tire size change. A kid I was talking to a kid on Facebook that seemed pretty confident that I could do it. I'm just a little gun shy after the last incident. What about codes? I pulled these off the bcm, and they don't clear.

I haven't looked at how the dodges do it, but it doesn't have the same options as the JK. From what others have said, when you type in the wheel size, it throws all sorts of codes, mainly abs codes, and maybe some transmission codes. I haven't looked into it yet on mine. The mpg doesn't actually change by changing it in the computer, only the readout will change. For instance, my mpg was between 22 and 23 mpg with 245/65/17. The 265/70/17 are something like 6% larger. That difference times the prior mpg came out to like 1.4mpg. Add that back and that's my correct amount. Therefore. 20.6 mpg now, is the same as 22 mpg before. Under both scenarios, the actual mpg hasn't changed.

Interesting. I got the impression that it changed the shifting pattern as well as the speedometer. I don't know. I'm just the new guy. I was also told we have to do a proxy alignment every time we do a change. Have you found this to be true?

It can affect shift pattern. I'm not sure what size you are running, but its not drastic. I believe you can adjust up to a 245/65, so the biggest you can get is only like 8% larger. In the lower speeds, you are only 2 or 3 mph off, so not like it would matter much. In addition to indicated mph, its also going to shift off of load. If the load is higher, then it will still hold the gear longer.

Only time i have done proxy alignments is when the odometer is flashing but maybe this is different. I have used alpha on the rams, other jeeps and dodges. There is a lot that can go wrong if you try to adjust settings that are not correct for the platform.

Those codes are not clearing? have anything not working when those codes are active? one is a comm issue. not sure what the other one is.

I bought her used and the only thing that doesn't work so far, is the radio was messed up. I actually got that fixed on my own. That's a story for another day. But, the washers never worked in front, and the backs worked for about a week. I changed the motor because that's an easy step, and the rears worked again for about 5 minutes. Then I introduced myself to alfaobd, and got the front sprayers to work through the single actuator page, but never the back. I will have the steering wheel assembly in a day or two, and am hoping this fixes my sprayer issue. But, everything else seems on point.

You are probably on the right track with the washer. I forgot to answer the proxy question. I generally will do it after most changes, or at least at the end when I am done. It doesn't take too long to do, and that way I know I'll have done it incase it needs it. I'm also not sure about those codes.

Just make sure before you change something, you write down the values so you can change it back if you run into an issue. Also, its best to change one thing at a time, that way you know what caused your issue.

Will do. Someone told me to save my proxy settings, too. I haven't found that screen yet.
You can't really save them. They just re-run every time.

A few things
1. You need a security module bypass
2. You can't change tire size
3. AlphaOBD doesn't change TCM parameters, it can only run diagnostics.
4. If you keep failing proxi alignments you may need a canbus blue adapter to successfully complete the proxi alignment

I've got the bypass, no tire change... also no global windows down? What's TCM, and why would i want to change it? Last, I haven't needed a proxy alignment yet, should I just get the canbus blue adapter now? Thanks for helping me get started.
