Does anyone know if an srt 6 instr. cluster will work in a limited ? Saw one on ebay a while ago, and thought it would be a nice upgrade if it was just "plug and play".

 

I'd agree, that 200 mph speedo would be pretty cool.

 

I've heard of a couple slk's out there that swaped the stock cluster for a Crossfire instrument cluster, but I'm not sure if anyone has tried the SLK instruments in a Crossey.

 

I doubt it would make your Limited go 200 MPH.

I am not sure if the Speedo needle would indicate the correct speed on the dial face has the numbers for the SRT-6 are scaled different and the signal to the needle would not compensate.

 

Possibly would have to change the speed sensor as well ?? Or is it internally regulated in the cluster assy. ?? Or is it controlled by the ECU ?? I would hate to buy one and not be able to use it. I'm just a poor civil servant. This is the first new car i've ever owned ! THANKS FOR THE INPUT !

 

If the price isn't too high I would be willing to buy it and give it a try.

 

Text below is from the Service Manual (not SRT6) - SRT manual has the same text and pictures of the 160mph dial - page 8J-59! Dash is a complex bit of kit - for instance the instrument cluster includes the FSS which calculates the service interval with information supplied over the CAN data bus from the CAB - Controller Antilock Brakes and PCM - Power Control Module!

CAN data required for the FSS indicator:

4 WSS signals for calculating vehicle speed and distance from the CAB

Coolant temperature from the PCM

Engine speed from the PCM

Load torque from the PCM

Speedo is actually driven over CAN data bus by the CAB. The speed displayed might be from the front or the rear, if the car is cornering it will use the front (an average I suppose?) if car is not turning but there is a rear wheel spinning that will be used as the highest wheel speed is then displayed!

Doesn't help determine if the SRT dash will work, I would guess it might - be ready to connect a lot of plugs though!

I am amazed if a Crossfire dash worked in an SLK - if it does it's a testiment to Chrysler / MB that they didn't need to change any devices so much that they wouln't comunicate! If it did work with the SLK's different wheel sizes I suppose it suggests the speedo change would work.

The instrument cluster includes four analog gauges.

IF the cluster includes the vehicle mileage there's probably a tie-in to the on-board computer to prevent tampering of mileage. My guess would be that the speedo itself is probably plug and play but the swap would be complicated by the need to deconflict the protection on the odometer. Probably a dealer type of thing where they certify the odo to the correct miles and do something to make it work with the on-board computer. Almost worth it to see the look on people's face when they glance at the speedo and see the (theoretical) max speed...

There is another srt6 speedo on EBAY. Price is $199. I'm tempted again ! What about the warranty ? I've only got 4,000 mi. on mine, and I'd hate to void the warranty. The one on EBAY has 5,000 mi. so I would just wait until 5,000 mi. to do the install. THANKS FOR ALL THE INPUT.

 

Any updates on this?
