I have little to no experience working with modern fuel injection and ecu's etc so please bear with me.
Am I mad to think I could transplant a honda D series engine (complete) loom and ECU into a much older car and have it work properly?
The gearbox isn't going with it and hopefully niether is the ignition but apart from that all other components would be tested and from the same car.
Stupid idea thats asking for endless nights looking at wiring diagrams chasing endless fault codes and ecu hissy fits?
Or
Best idea ever?

Probably depends on how old the donor vehicle is and how integrated the ECU is with other systems. Older stuff the biggest worry is likely the immobiliser.
Fairly sure the D series is reverse rotation…..

Yep, it's counterclockwise, which is the main attraction.
As far as I can tell the immobilisers can be problematic and as such are frequently removed. Allegedly it's quite straight forward.
The donor cars all all around 97-02. Honda went clockwise mostly after that.
I know some factory ecu's can be quite fickle, often relying on feeds from unrelated stuff scattered around the car. Like air con or speedo readings.
Thanks

If too many legacy things are tied into the existing ECU and causing problems it might be easier to use an aftermarket ECU. You should already have the sensors.
Maybe try the existing one first and if its problematic switch across.

I would have thought in that age range the immobiliser is the main issue.
The factory Honda ECUs of that era were regarded as quite “hackable” and got transferred to other cars as a result. There were a couple of quite good forums covering it, dunno if they still exist. I didn’t go that far with the idea as I needed 6 cylinder coverage

I found several ways around the immobiliser from custom ecu to deletes to several mini owners who just used the honda ignition and key.
Sadly other fitment issues put paid to my plan.
