Greetings from sunny South Africa.

I had a 20SEH engine in my car, until I put a rod through both sides of the block. The only other 2l engine I could get hold of was a C20NE. I've still got the same ECU, but I would like to remap it.

Anyone remapped the M1.5.2 motronic system, without a
piggyback? Any links / info on doing something like this?
