How much to pay for a 7749?
 

What have you guys paid in the past for this ecm? was it original or remanufactured? Anyone have one for sale?

Thanks,

Shopping around at junkyards or on the net should turn one up for under $75. 50 being usual.

Maybe I got screwed but I paid $100 for mine (used) out of a 1992 Syclone. Add $25 for shipping to Hawaii and the total was $125. There are so few Sy/Ty's here on island it would be pretty much impossible to find one at a yard. I found this 749 ECM on the Sy/Ty web forums for sale section (some guy parting out a wrecked 92 Sy).

I picked mine up from a wrecking yard for $50. I pulled it from a 1988 Grand Am with a quad 4 if I remember right.

Didn't SATURN5 use a 7730 in place of a 7749 and it worked fine? I believe that he did and that you don't need a 7749 ECM.

Yeah you can convert a 730 ECM to a 749 ECM. It requires you repin the 730 to 749 specs and replace the 1 bar map sensor with a 2 bar map sensor. The only advantage of the 749 over the converted 730 is the 749 has an extra injector controller and driver. This means the 749 can run low Z (P/H) TPI injectors but the converted 730 ECM running $58 code requires you use high Z (saturated) TPI injectors. Although you might be able to run low Z (P/H) injectors on a modified 730 if you mess with LJ's impedence converter.
