6spd Limp Mode after Regear

[jimmyjim]

I'd start with the Facebook group. A lot of good info there. Then start at page 235 and work backwards on the recall thread.

Good luck and I hope you are able to get it running again.

Thank you. Good idea to start at the end!

I see you posted there. Folks over there will have some good advice. I never put the software in so I haven't had to fix that problem but I've been following along to those that have tried a Tazer, J-scan, PCM software revert and all the other ways people are trying to get their Jeeps out of limp mode.

If JSCAN does not work as it has for some and not others the last resort is you can send your PCM to Hemifast Performance in NY and some have said they can get the new software out and revert back to the original software. May be worth giving them a call just to ask their success rate on that.

Yeah it seems hit or miss. Some people have had luck with the dealer being able to clear the code and get it programmed. And other dealers seem to shrug and pretend they have no idea what you are talking about even though this issues have been known for a while.

Jeep says they tried everything and cannot get it out of Limp mode. I called hemifast, for $285, it’s going to them. Get the shit software off there and start fresh

Sucks you have to pay to fix their incompetence but at least you'll know you won't be stranded in limp mode anymore.

You may also want to just ditch the stock clutch and go aftermarket.

Agreed, in time.

Is hemifast a new company ? I punched it in and got “Launching Soon” sign up for alerts. A search only got Facebook and instagram that I don’t subscribe to. Curiosity not appeased.

I'm not sure. They've been mentioned for a few months on the Jeep Recall Facebook group.

Update: had to have the ecu reflashed with “as built” spec software, then go in and change the tire and gear settings. Now it runs. If anyone is in need of this, these guys figured it out in 48hrs. Call them.
