afm electronics only

[89supra7mgte]

what are, if any, the differences between the afm electronics from supra 7mgte, lex sc300, and the lex sc400?

they all look the same the 300 and 400 have identical part number. I know the housings are different on the 400 but i am not concerned with that right now.

I recently had the 400 electronics on my, connector broke off, so i threw on one off an sc300 with matching part numbers and all seems to be working fine. no running issues at all.

Is it the sc400 housing that will cause lean condition in car if not matched with 550 injectors or is it in the electronics that will cause this?

Pretty sure its the housing/dimensions and sensors within it, I would think you kinda just proved the connector is the same, right?

yeah pretty much. I dont think the housing itself has any sensors just the adjustable set screw, and dimension size. just curious as to what would cause the car to run lean if it was elect or housing. thanks
