I'm not really sure if this falls under Mod Tech or Street & Performance since it kind of straddles the two for what I'm looking to accomplish, but there's some overlap in both areas. If it needs to be moved to the other forum, totally understood.
Here's the basic question: will the ECU from a 2002-2006 TJ work in a 2000 or 2001 4.0 XJ? I'm concentrating on only the 2000 and 2001 XJs for this now because a) they use effectively the same ignition system as the TJ, and b) I've got a 2000 This may be able to be applied to earlier XJs later on, but for the sake of keeping things as simple as possible would like to stay focussed on the 2000s and '01s.
Expanding on that: this thread asked if a Mopar in-dash sat-nav unit would work in an XJ. The short answer is that it won't due to the differences in the TJ and late XJ busses - but as the bus is provided by the ECU, would an ECU swap allow the sat-nav unit to work?
I don't have a TJ FSM or ECU handy, so don't even know if the connectors are physically-compatible - it also means that I can't really look up the differences for myself. My assumption is that it's a no-go without major wiring changes in addition to (at the very least) swapping out the instrument cluster.
Anyone have any insight on this? It's more idle curiosity right now than anything else, but I'd be interested to see if it has the potential to go somewhere.
