I am selling a B66B ecu removed from a Eunos car that was in perfect running order. This is the correct ecu for a Eunos 1.6 1989 - 1997, Automatic gearbox but check that yours is a B66B before ordering.

This ecu has part number B66B 18 881B, Mazda part number 079700-3051. The photos are of the actual ecu you will receive.  Please see pictures 3 & 4 for condition of the PCB; it is like a new part.  

This is a standalone, plug and play ecu so no programming necessary and no other parts to fit. Tested on my 1991 Eunos 1.6 Manual; yes, the auto ecu does fire up a manual car, checked for condition and guaranteed to work

Any questions please ask - I specialise in MX5 ecu, immobiliser and transponder systems.
