What to do with the gauge cluster...

[ryan_george]

I'll be putting the m20b25 into my eta when the weather gets warm, but I've got some questions regarding the gauge cluster. I've got the complete unit from the 325i, so should I just completely swap that for the one from the 325e? Or just swap out the tach? Both of them are MotoMeter units.
Now it would probably be beneficial to have a CEL, which the eta cluster doesn't have. So I'm probably leaning towards switching the whole unit.

Is there going to be any compatibility issues, even when running a full 325i + ecu?

Let me know if I'm missing something here.

Thanks.

One of you know-it-alls has to have some input! :D

just replace the tach and coding plug

Just switch the full i cluster in. :up:

I am running a 318 cluster in my 325i and everything reads right so I dont think you will have any problems.

the eta redlines at like 4500, so the tach would read really screwey, i just swapped in my tach, but im still in the process of getting it to work, but my dads been working on e30s since they were brand newat his shop, so im assuming hes right and you just need to swap the tach.

thanks, but my dad figured out the problem, its not in the cluster, just have to get the sensor or something to make it work, probablly gunna do it later today, but thanks anyway.
