apexi have released the djetro for ECR33 if you are after that
it inclues a map sensor and air temp sensor as a kit
but its djetro only, you can swap between models like autronic etc where you just choose the input type
the powerfc was always positioned as the cheap end of the stand alone plug and play
so thats why its set model and not customisalbe out the ass, but customisable enough
and i think retard tming based on knock isnt a feature because they didnt want it as a feature
it would be 3 lines of code to do it but i believe they didnt want it to back out timing because its too simplistic
i agree it would be nice to have it as an additional feature, ie off by default, enable and choose how many deg or INJ to correct based on knock etc
