A friend of mine from another list has a programmer...now I am trying to learn the basics of what we need to do. I don't have the time, nor money to replace the ECM, so I will have to work with this crappy 85' T/A computer. I downloaded a 85 Vette bin file that should work with my computer? What else do I need. I am running factory TPI from the old 305 except for 24# injectors and adjustable FPR. Has anyone else done a similar engine swap? The cam is on the "weak" side...

isky grind number - 201257/265

RPM 1400-5600
intake lift .465
exhaut lift .485
dur intake lift .257
dur exhaust list .265
lobe 112

Pistons are at errr...9.5-1?

Thanks ;-)

 

pssst? No one with a reply

 

Did the same swap on my '85 IROC and ran the 870 ECM for a while. To be honest with you, it will be cheaper to swap to the 165 ECM. To edit the bin file for an 870 ecm you will have to pay for the program (unless you know someone who has it) and that runs $100+ def file.
You can get a 165 ECM for $50 and Craig's "basic" prom adaptor for about the same, then use winbin to edit the bin file for it. Also in the cost are 2 $14 relays and about 4 hours of your time to switch the harness wiring for the 165.
You'll save a few $ and have a much better ECM with more support and more parameters to tune to get things right.
Not to mention a computer that communicates at the faster 8192 baud rate.
