Hi just removed my ECU on my 87 t2 and the label reads ECI not ECU & the # is n332 18 881 instead of n332 18 880 i beleave the 881 is a reman but why does it read ECI . Tony

 

My 87 TII still has the original ECU and it is labeled exactly the same as yours, except it says "EGI" instead of "ECI". I have no idea what "EGI" stands for, but I'm guessing your unit is the original, or an exact replacement.

Edit: Just to be perfectly clear, my ECU number is N332 18 881. The car was manufactured in March '87.

 

My bad mine does say EGI N332 18 881 just a typo mistake.

 

"EGI" (Electronic Gasoline Injection) is what Mazda called their early EFI systems. It's actually cast into the top if the intake plenum on a few Mazda engines including the GSL-SE's 13B ("RE-EGI").

 

Is that good , bad, or same thing as the ecu. I want to send it in to have the rtek 1.7 chip install. I'd like to make shure im sending in the right thing. Tony

 

EFI/EGI (electronic fuel injection) refers to the complete system. The ECU (electronic control unit) is the EFI system's control box. The ECU is what you'll be sending away...

 

So im sending in the hole unit that says EGI # N332 18 881 is this right BTW thanks for the help. Tony

 

Yes. That whole unit that you've been describing is your ECU. A small metal box, about 7x7x2, with a flat cover on the front and back, a bracket at each end, and three yellowish-green connector sockets at the bottom.

 

dont forget to get the 720cc injectors if your getting the rtek 1.7
