Right a friend of mine has just got a rs 1800 throttle body & cult ecu from a 94reg car which he fitted 2 his xr2i however with the new ecu plugged in the engine wont start fuel pump works but it just turns over i know cult ecu,s can be a pain with compatability but is this just a fooked ecu or has sumthing else got 2 be changed any ideas would be appreciated thanx
Ps everything else is standard 105ps

 

Do they have coded keys?

 

Is the XR2i external EDIS? If so, you cannot do a straight swap without a little bit of re-wiring of the loom because the CULT ecu has internal EDIS.

 

the xr2i is external edis ! so which wires hav 2 be alterd thanx for the help

 

You best get yourself a wiring diagram mate it won't be easy to explain on here
