m50 convertion w/ m42 cluster

[zav3n]

i just finished my m50 swap and it is amazing but the rpm's are way off cuz it is the m42 cluster. i was wondering if had to get a 325 cluster or i heard that there is a chip that i could change w/ the 325i one in the back of the cluster .
thanks

i believe you just need to swap the 4 cylinder coding plug in your cluster, for a 6 cylinder coding plug from an e or i m20 car.

^ Make sure it is from a 325i "i" car and it will be right .

you don't even have to remove the cluster. Just remove the trim piece right below it and pull the plug on the right side out and snap in the 6 cycl plug. I finally got around to switching the coding plug on mine, I kinda miss the passenger's expression when I take it to 15 grand though.

Hahaha! 02stu is right, you don't need to remove the cluster.

It turns out the Super Eta also has the same coding plug as the 'i'--a 468.

Ok granet you guys were talking about an M42 engine being the 318 yes, would and one know what i would need to do if i had the 325e 2.7l motor and i only have a 5k tach. do i need to buy a new cluster or can i just wire every thing up and have it be off on RPMs for a little while im fine with that sense its winter now and i dont drive hard in the winter i just want the speedo and gas and colant gauge. If i just wire every thing up it should work and just be a smidgen off by a couple k' rmps

You know its kind of strange but i swapped my coding plug for a 325i one and i have no idea where the hell redline is.

when i hit 7k the thing bounces back violently and then goes back...very strange, i scared the shit out of a passenger when that happened.

i don't have the obc hooked up, could this be a reason?

what is the redline on an m50 motor?? what about with EWS delete chip?

redline should be 6500.

I'm not sure what is your trouble - hope you figure out a solution!

Here's a pic of mine - it's a standard '468 plug, just from late-late E30 production.

Why is that even out of your cluster?

would be pretty hard to sell it otherwise...


I think the better question is, why is your name 90m3 and your avatar is a non m3 =P

As I used to own a (90 M3) when I signed up, or just to confuse people like you
