difference between our ecu's and the the e36 obd's for FI?

Whats so different about the 2 systems and why does it seem so much easier for e36's to run piggyback or change there engine management systems for FI. i guess this is kind of leading back to the age old question why are e46 so hard to tune. is it just a time difference in that the e36 has been out for so much longer?

95 and below e36s have OBD I. I think the 96+ E36 and all e46's have OBD II. OBD I was made before the gov. put certain environmental restrictiosn on the engines, thats why theyre so easy to tune.

most e36 r obd I.....it's HARD to find one with an obd II

this is why e36 m3 is much deadlier than the e46 m3 when it comes to get down dirty with the crazy mods

The difference is about 12000 lines of code.

Its not only the code....the difference is that the government made tighter regulations AND added a bunch various sensors etc to the mix. O2 sensor, MAF, all that kind of crap.....with OBDII came a crapload of stuff that needed to be added(not sure which sensors exactly). Before you change the code, you would need to take all that crap out. Its been done on E36's m3's....the so called OBDI conversion, but never on an e46.
