I recently found an MC28 PGMIV unit with the cool card ignition at the local wreckers, and I'm thinking about transplanting it onto my MC21.
I've heard that the PGM3 can be a bit useless at the best of times (I even once heard it referred to as "broken" lol) and that the IV is way easier to tune, since you just need to get the different cards to change the ignition map.
How easy do you think it will be for me to make the swap? I am aware that I will need to do some rewiring but should I look into buying any other parts like a racing loom or the 28 flywheel? I figure since the 28 parts will be a little bit more technologically advanced it will be quite a big job.
Look forward to any feedback you might have, thanks! _________________ RBRBRB
