Just wondering. If one were to get a replacement ECU for the S60R and have that tuned, say by IPD, could one take his or her ECU off, set it aside, use the tuned ECU and replace the original when it was time to take the R in for service? I take it that the data in the original ECU might not be quite up to date but how is that your fault? The dealer would not see a re-flash as having been performed. I looked on the net and found an ECU for under $900. My extended warranty was more than twice that. If this were possible, it would be a way of tuning the car without great risk to the warranty, or am I missing something?
