Not that I have heard of to date ,maybe eithan has ? Mine works fine on all 3.0's the only time there has been a problem it was the multiplugs under the ECU had come apart slightly .

Maybe the problem is after the tech 2 ?

Problem solved, the dump of the flash 29f200 was corrupt, it lacked much in the beginning.
I bought a used ecu, with which communicated Tech2, soldered EPROM and injected the immobilizer code from my dump ...  Very Happy

Hello everyone I haven't given any news since.
To sum up, I bought an ecu from you in England, plugged it into the Trooper, and it communicates fine with the Tech2, but it won't start the engine.
I unsoldered and read the flash 29f200 of my ecu, copied the start codes, then pasted them on the flash of the English ecu, the engine starts, the Tech2 communicates, on the other hand I have a MIL fault, ( immobilizer not coded)
After a number of starts, the engine does not start anymore...
Here, I'm back to the beginning, I never found the solution to this problem
The top would be to completely remove the immobilizer to be able to drive with the English ecu.
