Mazda 079700 3041 / B64J 18 881 Denso manufactured Engine Computer

Up for sale is a Working, in excellent condition Mazda ECU. Should fit 1990 1991 1992 1993 models, perhaps others as well. See part numbers at the top of the listing.

As always with this type of component your best bet is to match the part number to the one on your original ECU. 

This unit offers a 30 day functionality warranty. A faulty ECU is one of the most common no start or random stalling problems with these cars. These can also cause issues with erroneous check engine lights, idle control problems as well as emission control & cold or hot start problems. If your car does not have these issues but you intend to keep it a while, I recommend our customers keep an extra ECU in the trunk. These units now have to be special ordered from most dealers new for big $$ (often times over $1000!), and you can never find one when you need one. Even now finding a good one second hand is getting to be quite difficult as these cars get older.
