If after market ECU's can be programed for any kind of TB's, can you not reprogram the factory focas ECU to run TB's on a Zetec?. Just curious, I dont know a lot about ECU's,so if thats a stupid question you can probibibly tell.
the problem with modern factory ecus's is they often have everything running through them. Most run run a CAN bus linking to several other minor ecu's like a Body control module, monitoring all sorts of things like headlight delays, interior lights, alarms, airbags, ABS etc etc. To run a modern factory ecu with an engine swap you either need to be able to disable all these extras in the programming or fool the ecu that everything is still working as per the donor car. For an engine swap, fuel only or fuel & spark are probably all thats required making an aftermarket ecu a better option. If your changing to quad TB's you also need to consider running ALPHA-N rather than the MAP (Manifold pressure) or MAF ( Air flow) which is used with a single TB. The online megasquirt manuals make a good read if you have plenty of spare time.
