RPMS will be off if you use a 6 cylinder cluster. Odometer will be wrong. Might depend on the year. __________________ ...steven BMW CCA #146825 1996 BMW 328ti • 2003 MINI Cooper S • 2016 M235i www.bmwcca.org | | | 03-15-2012, 09:28 PM | #3 | Senior Member Join Date: Oct 2008 Location: Los Angeles, CA Posts: 1,464 | Only difference I've found between the ti cluster and other E36 clusters is the lack of a vacuum (MPG) gauge. You can use other non-ti clusters in the ti, but the vacuum gauge will not be functional. I've also heard that the RPM's will be a little off between 4 and 6 cyl. clusters, but I'm not aware of the odometer difference- doesn't the odometer read off of the same sensor as the speedo and therefore is a function of the final drive, regardless of what's under the hood? EDIT: I misunderstood Steven's comment about the odometer- yes, the odometer reading will not match on a different cluster, but I don't believe that the odometer's ability to accurately log miles will be affected with a different cluster (unless, of course, you've changed the stock wheel diameter- then both odometer and MPH will be slightly off).

However, as mentioned the engine RPM's will be way off if you install a 6cyl cluster on a 4cyl car or vice versa. Another thing to consider is OBDI and OBDII. If you have a '95 318ti, it's OBDI so you'll need an OBDI cluster. If it's '96 or newer, it's OBDII and you'll need an OBDII cluster. Then there's the issue with mileage. When you swap in a used cluster, it already has a mileage reading stored in it which likely will not match the mileage of your car. Therefore, to prevent shady people from trying to cheat the system, BMW incorporated a manipulation dot. This is a tiny orange dot that illuminates on the odometer display. You can go into the cluster "test mode" and reset the manipulation dot, but this will take on the higher reading of either the cluster or the vehicle's mileage. As for the MPG gauge, there's a few writeups online that explain how to make it functional on cars not equipped. It's just a matter of running a vacuum line. So to answer your question, yes they are interchangeable. Depending on the year of your car, you'll want to get one from the same OBD generation. Unless you have a 6 cyl swap, you'll want to get one from a 4cyl 318i, 318is, 318ci, 318ti or 1.9L Z3. | | | 03-16-2012, 12:02 AM | #5 | Member Join Date: Feb 2012 Location: YORK,PA Posts: 74 | thanks for answering the question, This was the answer I was hoping for. I have been in the process of rebuilding the dash in my 318IS and the TI has the Cluster shroud that is easier to integrate into the new dash build. So I will still be using the OEM cluster,just needed to know if it would fit phsyically. | | | | Currently Active Users Viewing This Thread: 1 (0 members and 1 guests) | | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is Off | | | |
