1.9jdtm cf3 to cf4 conversion
Has anyone ever attempted this and is it possible? Struggling with a tune on a hybrid with the cf3 engine we are running at moment and tuner is saying it's down to the edc15 ecu not being flexible enough (ie we can't have a bigger rated boost sensor plumbed in as the ecu doesn't have the ability to change it), so rather than spend 1.5k on a custom ecu we were going to look at converting to cf4. I'm aware of injectors, lamb sensor, fuel pump, and cam belt size (supposedly due to fuel pump). Is it just a case we can swap all these and just a cf4 engine loom and ecu on and it should run, or is there more under lying differences between the 2 engines?
