‘07 Speed3 ECU

So I have a 2007 Mazdaspeed 3, I sent the ecu out to get repaired and sent back to me. USPS seems to of lost the package back en route to me. So I’m stuck trying to find a replacement which seemed hard enough to do.
Original Part number that I took out was #L34C-18-881F
Does anyone know of other part numbers that are interchangeable so I can get my Speed back or am I left with a pretty big door weight?

 

Have you looked at eBay? I put that part number into Google and found some remanufactured options.

I also would look at

I know you can find a used ECU for the car out there somewhere.

 

Most of the ones on eBay that I found as refurbished were through a company Flagship One who is the company I am dealing with currently that tried repairing my ecu before usps lost it and they didn’t have anything in stock as they were “mislabeled”
I was able to get one from Chris Ward with CW Turbochargers for a very good price.

 

Once you grab a new one you still have to go to Mazda to get them to flash the correct vin to you don't you?

 

Yes I would, but one of my techs has the same scan tool/computer necassary to do that. Same with re-learning the keys.
