Rubicon issue

Image Group · 07-09-2009, 03:51 PM

Hey all newb here. I have an 03 Rubicon that I used a Hypertech Mod on. I changed a few things while out wheelin. I set it for Premium fuel, and performance mods. Some Jackass stole the Module and I'm now stuck shelling out for Premium fuel. 2 dealers have said they cannot flash the system to return it to stock. Hypertech has been no help either. Other than replacing the ECU anyone have any ideas to get it back to stock?

Dont quote me on this, but you may be able to reset the computer by disconnecting the battery and touching the pos and neg leads. Im not sure, but this was the fix when my jeep decided that 5k ft from sea level ment that she would no longer run.

That sounds very risky. I've always been told never to cross pos and neg unless your either
a) bored
b) dumb
c) rich
d) all of the above

You take them off the battery first! There is no power, it just grounds and resets the ecu.
