I'm trying to figure out if I'll be able to retain EVAP when swapping my LS2 into an E36 (1998 328iS BMW). There are a couple of guys who did this successfully on the E36 with the LS1 and 411 PCM. I have no idea if the E40 reads the fuel level signal the same way the 411 does.
If I understood what I was reading, another swapper with an LS3 and an E38 PCM had to create a serial conversion for the EVAP fuel level signal (using an Arduino box). I know the E40 PCM needs serial information for the air conditioning request signal but I have no idea if it reads the fuel level information like the 411 (analog?) or the E38?
Any help is greatly appreciated.
Thanks.
