My question is can a ECU from a 73-74 2 liter be installed in a 75-76 2 liter? Are they interchangable? If they are not, does anyone have one for a 75-76 2 liter? I need this as soon as I can get it. If they are interchangable then I just need one whenever I can get it.

73-74 is D-Jet.
75-76 is L-Jet.

75-76 2 liter is not L-jet, it is in fact D-jet. The 1.8 was the only engine with L-jet.

2liters are D-jet. 1.8s are L-jet.

75 ecus can be used on 73 motors and vica versa, however, The ecu must be matched to the mps, tps, and maybe a few other components. Visit Brad Anders site for part#s for compatibility. Remember, we're talking 2 liters. 1.7's are a different animal and will be too lean for a 2.0L.

Actually, as I recall from Brad's site, the 2.0 ECU, at least for '73, was identical with the 1.7 ECU. they only added some external resistors for one or two of the sensors (I think the CHT), and used bigger injectors on the 2.0.

Brads site list 4 part #'s for 72/73, but only the 037 is to be used on the 73 2.0L if I read it right.

I have one if you need it.
