NEED HELP PLZ READ!!Si Board from 325i to a 318i - BMW Forum

I bought a new instrument cluster from a parts car which was a 325 and then i put it in my 318i. everything works fine except the rpm gauge was wrong and works but it doent go where its supposed to. I was wondering if it was bc it came out of a 6cyl to a 4 so thats why and maybe it can be programed to my ecu or maybe just put my old Si board back in. if anyone has any info please reply. thanx

why did you replace the cluster in the first place? what was wrong with it?

i took it apart one day to tighten the nut on the back of the fuel/heat gauge and to change the batteries but i broke one of the nuts. i tried to fix it and couldnt so i bought a used one and switched the speedo so i had the same miles. everything works way better than it did b4 except fot the rpm gauge. it works but it doesnt show the right rpm. i am going to try swithing it with my old si board sometime but i havent got the chance yet.

It's part #11 on the attached diagram, found below the temp gauge on the front side of the instrument panel. A look at the part number (62111394321) shows it unique to 318s with M42 engine. 62111385468 is the code plug part number for M20 325i.
