I didn't know that I had to - in my order notes I asked if cross-ship was available since this is my DD

found a form on the website for ECU/TCU
http://www.eurocharged.com/ecu_form.pdf

I'm gonna send both ecu and tcu in together..too cheap to spend the extra dough on the cable...how much insurance should I get? I don't know what these things are worth.

this is not Mercedes pricing but from parts.com
looks like the TCU is ~$835 and ECM is $2,500

Those who've done the TCU upgrade, how do you like it? The one thing that concerns me about the TCU is the raised RPM (not sure by how much).

Any idea when parts will ship? Blower pulley/heat exchanger?
