Jb4 problems, anyone else?

[pony2bronco]

Installed everything according to the pictures / lethal videos. Now I have check engine, service soon, low idle/power loss, pre-collision assist not available.

Codes: PC60B, PC66D


Tried updating to latest firmware and same result.

Double check those code numbers. They aren’t correct.

Okay. They must be JB4 specific codes then. Those aren’t Ford codes.

I've been trying. They don't have phone, no email response luck yet. They did have a rep on their internal forums reply, but it made no sense. Said that my version doesnt use the TMAP plug and go back to factory and then email for new firmware. No reply to emails requesting, and Lethal confirmed that the 2.7 definitely uses the TMAP plug.

On mine I used both plugs.

Solved, kinda. They had a batch of JB4 for Bronco sent with the wrong chips inside. Hopefully can get a new one soon.

Literally just installed mine today. Same problem. Guess I’ll have to call also. Keep me updated on yours

I had a self inflicted issue on mine I was expecting to pay for. They took care of it. Shipping and support was really good to. They will get you taken care of.

Nah its just the JB4. another member had an issue with their CS and support as well.

Replacement chip was a pain to bend and install right, but it worked! Still having some issues though getting it to read the obd2/display gouges, wondering if I need to replace that next.

On the bright side - I thought I was gonna have to go into Forscan to clear the check engine light (was still on even after removing the JB4 and driving stock), but somehow without doing anything the JB4 cleared it with the correct chip in.

I’ve never been able to get the gauges to work either for some reason
