Quick M30 335i Poll

[SpunkyE30nOk]

After you put your motor in did you reconnect your OBC? I want my E30 to be as close to a production 335i as possible.. I have an uncracked dash to put in and my light for my OBC is out currently. but the computer itself still works. When I do my swap i still want to keep it in working order. If you did hook up your OBC after your swap was your mpg some what accurate or wrong b/c its designed for the m20

[NomadE30]

well i am assuming you are going to change out the ecu's with the wiring harness. Check realoem.com to see if the OBC are different in the 535i then the 325i. I can't imagine a problem unless your making your m30 better then stock with bigger injectors and such, but i am sure it still will measure it fine

It didn't need reconnecting as I recall... I plugged the new harness in at the fuse box, and it was a square plug car.

what harness did you use? modified m20 or the harness from your m30? Im going to use the harness from a 87 635csi since thats what i got the transmission from

I didn't even bother with an OBC. I went straight to an analog clock.

I mostly use my OBC to check my fuel range *yes my fuel guage works*, mpg highway and city

I like having the computer too.

Mine does not work because i lost the loom in a flat shift.

Anyone have a spare OBC loom for sale?
