Hey folks, I have the stock ecu leftover from my 2012 14r; any idea what I should ask for it?

I believe a brand new one is over a thou. Half is fair to ask for something in good condition (near new). I have heard of used unflashed ECUs going for less than half but start at ~$600 and go from there. Also, check Ebay prices. If you sell there, you will have to pay about %15 to Ebay.

Unmodified on Ebay they will sale probably somewhere in mid $200 to mid $300s. When i bought my second ECU (for a '13) about a year and a half ago, I got a pretty good deal on it in that price range. Gen 1 ECUs can go for low to mid 100s.

You might see ECUs up there for more, but chances are they won't sell and someone will come in with a lower price.
