I am getting ready to swap in a 16197427 PCM and throttle body from a 305 van. This is going into a 63 comet with a 302 and a C4 transmission. I've mounted a reflective optical sensor to the speedometer that should work to provide a 2k PPM VSS signal to the PCM. I have most of the parts and will start the conversion soon. I have a dataloging cable and a GQ-4X4 programmer and Tuner Pro RT. I just swapped a 7427 into my 90 G20 and have been making adjustments to it, so I have basic familiarity with tuner pro and the 7427.

Is there a preferred 305 bin to start with? The PCM and MEMCAL that I have were from a 350 BJYL that I bought off of ebay. I was originally going to install a 7747, but after more research, the 7427 seems to be the best way to go.

What settings should be changed for the non electronic transmission? I've seen recommendations to configure it as a manual transmission, but I suspect that if I did, the PRNDL inputs would be ignored and iac/idle learning would be affected by the load from the transmission in gear. Should I configure it like I did for my van with a 700r4 using the torque converter clutch only flag? Would that cause any problems for the computer or any drivability problems?

Thanks in advance
