I have a 91 318i that i am in the process of switching out the digital clock for a 13 button obc. the good news is that i have a complete donor car to scavenge parts from. the bad news is that the car is an 87 325i. I read somewhere that you have to change the chip in the obc to make it work with the 4 cyl engine. I don't have one for the 318. Anyone know where i could get this part used?
Related to the above, i really would like all of the functions to work, but i recently had someone rain on my parade when they told me that the obc cars have tons of proprietary sensors that the non obc car does not have. is there any truth to that statement? if so, how much of a pain is it to swap them over? i know of the temp sensor, perhaps one in the fuel tank..... Could it really be just as easy as plugging in the harness and the computer?
the 91 is an airbag car, which i really don't care that much about. since the 87 is not, does that mean that the turn signal stalk is not compatible? as far as the steering wheel is concerned, people say the first gen airbags can cause more injury that they prevent. Besides, i just bought an early style Momo Alpina wheel that i am dying to use. how the heck do you get the air bag off anyway? I suppose i could go on an on with the q's, but hell.....
peace!
