Well, I got my ECM back from Wrangler Fix. Mark was nice enough to delete the SKIM function again (Thank you, Mark!). This time I removed the SKIM module BEFORE plugging in the ECM. It starts and runs and keeps running. But after 10 seconds, the security key light comes on and stays on. Is there...

Yes, I have the 6 speed manual trans. This sounds a concerning, but I trust your advice. Have tried this and it worked? Worked when otherwise couldn't flash? Can I make a little better jumper and leave this plugged in? Or do I have to remove it before driving the Jeep? Thank you very much for...

No, I have never written to his Jeep before. But I have written to my 2008 Trailblazer without any issues whatsoever. I don't have any other electrical items such as extra lights, fans, or a winch on my Jeep. I will try it one more time without a charger on either the laptop or the Jeep battery...

I am not trying to download it into a different PCM. I am simply trying to change the rev limiter from 5300 to 4300. I am trying to upload it, make the change, and then download it the same PCM it came out of. No stealing involved

Yes, I have the correct license. If you don't have a license for the PCM, it won't even let you get to this screen. I am able to upload to the laptop just fine, but it seemingly doesn't even try to download to the ECM. All I am wanting to do is lower the RPM limit to 4300. After I get that...

I am trying to get a custom tune to transfer from laptop into the ECM using HP Tuners and I keep getting a “Writer Erase: Failed" error message. Does anyone know to fix this? I have tried everything I can think – full battery with a charger on it as well as the laptop plugged with an extension...

That was meant to be funny - but also serious too. I know there is NO OEM sensor check function in the ECM. But the Wranglerfix.com ECM does (to me) seem to tolerate aftermarket sensors better than the stock ECM. After replacing the ECM, I have not had to return to AutoZone for a crank position...

I am not running Mark or Wranglerfix.com down the road. Wranglerfix.com saved my Jeep from being totally inoperable and it has been many years since I had to replace the crankshaft position sensor. I meant what I said on May 10th, 2020. The Wranglerfix.com ECM seems to tolerate aftermarket...

Nope, NOT Wranglerfix.com! When I purchased my Wranglerfix,com years ago. I asked him to delete the SKIM key and make some other changes to the programming - NO REPLY - ECM arrived WITHOUT any of the changes I specificity asked for! Now my SKIM is going bad. I am trying to use my HP Tuners to...

Dang it, I really had my heart set on one of those aluminium radiators off of eBay. They are really cool, no pun intended Mine us cracked at the top and leaking. I guess I am getting MOPAR 55037652AA from Rock Auto. This thread is an aluminum radiator buzz kill!

I have noticed that since I installed my Wranglerfix PCM, several other codes stopped showing up as well because the Wranglerfix PCM is much more tolerant of aftermarket sensors. It seems as if the OEM sensor check function has been removed from the revised PCM. If you own a 05~06 Jeep you must...

Not being able to reprogram for mods such as a supercharger or turbocharger is (perhaps) NOT exactly true. Look at the very first comment, the one all the way at the bottom, on this video below. Rob Sullivan says (and I quote): "I had my pcm from Wranglerfix in 2 days. I installed it, then my...

I just went thru this nightmare with the Dorman 56398. The only solution is to use a wire wheel to get the paint off of the threads. The threads look too fine, but when the paint is removed, it matches up. after the paint is removed from the threads, you have to use thread sealant to replace the...

Please watch the video ...is this amount of wobble normal? Harmonic Balancer Wobble Video This a brand new harmonic balancer that I installed on my 2005 Jeep Wrangler Rubicon 4.0L The old one wobbled just as much. This amount of wobble is the reason I changed the harmonic balancer. The Jeep...

You are a 100% correct on that and exactly the reason why I am soon to be yet another Wranglerfix.com customer! I am convinced any PCM from anyone else is a waste of money!

Do you know someone local that would willing to let you swap PCMs? I would be interested to know if the problem stayed with the Jeep or followed the PCM? Though I am not sure my idea is even possible...

To test the the O2 sensors, I rigged up wire leads from an O2 sensor so I could check for voltage. Basically, you make a Y or T tap onto all 4 wires on the O2 sensor. This allows you to check for positive voltage to the O2 and also a ground to the block. You only need to do one and best to use...

Is there anything else left to do? Sounds like you have done everything! But just because you replaced the PCM does NOT mean that you replaced it with one that works! All to often, many people replace the PCM only to have it fail again. Many honest PCM rebuilders won't even touch a factory '05...

miss80five, Have you tried rewiring the fuse block? There is a TSB on it. The details are in the link. I did it to my Jeep and it wasn't too hard. It did not fix my problem, but I don't have the same exact problem you do. You may also have a bad computer? Solution for 2005/06 TJ/LJ O2 Sensor...

The issue has been resolved. Mark is a man of his word and if I cast shadow upon his integrity then I was wrong so please accept my apology. I never once had any doubt that his ECM would fix my problem. I spoke to several ECM vendors yesterday and only one was honest enough to tell me not to...
