For what it's worth, I had a great customer service experience with Wranglerfix. I called Mark and we talked about my Jeep for over half an hour. He told me to order a PCM, and if it didn't fix my problem, send it back for a full refund. I mean, how can you go wrong with that? He stands behind his product and he's willing help customers.
After installing the new Wranglerfix PCM, Big Red is still running like a brand new Jeep with no issues at all.
I never did get that sweet Wranglerfix Tervis tho. 🤣🤣
 
On the site it says that it is not tunable. Is that still true? This would not allow tire size changes and my Banks system would be rendered useless.
The only part not a KT to be updated is the software. You can adjust tires, gears and speedometer as normal.
 
It comes with stock programming. I don't
I'm sorry, but I'm not sure I understand. I can or cannot use a tuner on your PCM?
It looks like spellcheck got me. You can adjust tires, gears and speedometer with a tuner. Software cannot be updated and no turbos or chips.

Thanks for the reply. Well, too bad. Glad you been able to help others though. Luckily only happens on mine when cold and only once. I should feel lucky.

Hey guys, I made a quick you tubes video on my @Wranglerfix PCM that I installed on my 2005 Wrangler Unlimited Rubicon.
Check it out and let me know if I missed anything, or if the video needs to be redone. I'm by no means a professional you tube vlogger, but maybe this video can help someone who might be having PCM problems.

Did you intend to include a link?

@GorillaBiscuit Thank you for your testimonial, sir. It is greatly appreciated.
No worries! I hope the video is OK, I just hit record on the phone and rambled on a little bit. Lol
But, honestly I really am happy with it and I just wanted to share my experience. If it weren't for your PCM, I would have sold the Jeep a long time ago.

I purchased and installed a Wranglerfix PCM..Mark was awesome..I did my homework, my issue was with the hard shifting and transmission codes i would get in colder weather...The P0058 code could be your PCM. I Just had this code..open on bank 2 sensor 2..I replaced the sensor, it didnt fix my issue, my header bolts had backed out and i had an exhaust leak so my down stream O2 sensor was not heating up as fast as the PCM thought it should. Also About 18 months ago(pre Wranglerfix pcm) i had all 4 O2 sensor codes come up within days of each other...it was bad cats...but of course i replaced the O2 sensors before checking the cats because it was easier to do...If you are only getting O2 sensor codes and not having transmissions issues(codes or hard shifting) you need to isolate the problem, installing a new PCM without checking your cats, ensuring they are not broken and are tight and the crush gaskets are good and replacing your sensors with new NKGs...probably wont fix your O2 sensor issues.
