I am parting out my 03 S600.

I am selling my Renntech Ecu/Tcu from my 03 S600 . I am accepting fair offers. I will need your stock ecu/tcu to trade.

I also have a set of Maya 20" wheels for sale with 2453020s and 2852520s. 500 miles on the tires and the rims are in great shape.

Thanks

A couple of questions:

- are '03 and '04 ECU's the same?
- how long have you had/used your Renntech?
- Original owner of the Renntech?
- Any issues with moving ECU's from one car to another??

I'm interested based on the answers above.

I have had the unit in the carfor a yr. It is a piece of cake to remove the ecu and tcu, takes 5-10 minutes and there is no issue.

03-06 are the same

I purchased the car with it installed, after a yr of ownership I bought another 600tt and did the ugrade on my second car with renntech. Now I need to return the car to stock so I can sell it to my buyer at his price.

The Renntech upgrades are on file with Renntech, the car is night and day difference from factory settings.

are the ECU's VIN specific? That would be the only issue I could think of. The TCU's for sure can be swapped from car to car with no issues.

I don't think it that easy. For one thing, you won't be able to start the car.
