Hello Everyone,

 

I've got a '99 Impreza 2.2 5mt and a fried ECM.  

Are these interchangeable as long as it is for a 2.2?  Is there anything special I need to look for when finding a replacement?

Does anyone know where to find one?  Is there any programming or other special concerns when replacing it?

 

Cheers!

This shows '99 only but AT and MT use the same: https://parts.subaru.com/p/Subaru__/Engine-Control-Module-ECM-Engine-Crankshaft-Position-Sensor-Bracket/49232072/22611AE510.html

I'm not sure about the '99 being MAF or MAP based? If it has the MAF by the airbox then it's likley a  one year only ECU, since I believe the '00-'01 EJ22 were MAP. 

 

Here's one on Ebay: 22611ae510

P.s.s this age they should be PlugnPlay - remove the battery cables 1st if you're not familiar w/the process.

 

Also, check the EGI (?) fuse under the hood- the big one. Might have gotten blown, too.

I’d be working out what fried the ECU first! 

No use spending good coin on a replacement ECU only to have the same thing happen again!
