Chevy Impala Cluster.

[FFjwhite]

Ok Well I was looking at ebay and I found an intreament panel and I am looking to replace my OEM One with this one.

Will this work? I like how this is set up better than the OEM one. Thanks in advance and all help would be great. Thanks

A 2001 cluster will fit, and will work, however, the Brake light will be on all the time, due to software changes between 01 and 02.
In addition, whatever mileage is on the new cluster will show up when you plug it in, since the mileage is stored in the cluster.
You can get the mileage changed to match what is on your car now. Try this link: http://www.bbengineer.com/
He can also help with any other service for the cluster.

Ok so here is my next question, If I get one that was made for an 02 that would work? Also seeing how that the one I want has an RPM gage, do I have to do anything different to the car to get the RPM working?

[Iflylow]

Yes, an 02 cluster will work. You do not have to do anything to the car, the RPM signal is already sent to the cluster, even though you do not have RPM right now.
Any cluster from 02-05 will work. However, if you have the 3.4L engine, and get a cluster with an oil pressure gauge, that gauge will not work. The 3.4L does not have the right type of oil pressure sending unit to talk to the cluster.

Ok sounds good. Thanks. Now I just gotta find one that is an 02. Thanks

Clusters from 2002 - 2005 are all compatible, so you don't have to find specifically an 02 cluster.

Ok so now here is another question. I was able to find a used parts place here and there is one what is called Opt U11. What is that? Will that work?

[HeMi101]

U11 is the RPO code for "POLICE INSTRUMENT CLUSTER, CERTIFIED SPEEDOMETER" And I'm pretty sure that's the basic 3 gauge setup but has the 140mph speedo.

Randomly just brought this up on Ebay for ya, cuz i take it you just want a tach.

Ok, does anyone know how to do it like BBEngineering did? I want to do it myself but I am not sure how he did it. Thanks

[HeMi101]

How he does what, change the millage?

The Millage is stored inside an EEPROM that is embedded in the processor in the cluster. It's not as easy as using an EEPROM programmer.

Ah Found what i was lookin for:

You can't use an EEPROM programmer to get to it, you need an ICE for the processor along with the programming software and knowledge of the encoding algorithm used

You can do it yourself if you want to spend the hundreds of dollars for the HW and SW needed

No I am wondering how to change the Regular Cluster bulbs to LEDs. Thats what I want to change.

Oh and I also found an 2003 Cluster and it works like a charm. Do you think if I take the Cluster to a Chevy Dealer, do you think they will change the mileage?

[Iflylow]

It is unlikely that they will have the equipment needed. They will probably be able to send it off to someone, however, I'll bet it will be significantly more than the $55 BBE charges.

[HeMi101]

Oh doing the LEDs isnt too bad if you have some knowledge of Electronics and soldering. I believe BB made a Tutorial and I gotta find it. I did all my switches and cluster my self too:

Edit: Cluster LED How To

[FFjwhite]

Oh ok, sweet I will have to work on that tomorrow after I go to Radio shack and get some resistors. I will post some pictures after I get the job done.

[gwjturner]

That's good information about the U11 option. Does anyone know what the UB3, UC9 or the UH8 options are?
