I've noticed that every Mitsu Part # I've seen starts with MR/MN/MZ etc...

Yesterday I removed my stock ecu and found out that it starts with 1860A299, underneath it E6........

I called my Mitsu dealer and asked for the ecu number and they gave me the same thing I found behind my glove box, they told me 2005 models don't come with MR/MN anymore they're all numerical.

Does anyone else have a numerical ecu part number ?

 

That's correct. All the '05 ECUs we have seen do not share a traditional part number.

 

Thanks!
