1) Motronic 1.7 w/ genuine Turner / Conforti chip. Obviously the case has been opened. The ECU + chip were tested in my 318iS today and functioned 100% fine. Stomp test returned 1444 after driving, which means no issues. $200 shipped in the US lower 48

I'm interested in this for my 318i. Tell a novice about the "stomp test". I'm at 45215. Paypal?
