no volts at ECM pin for cooling fans
Eric told me that the chip is set for the fan to come on at 166 but it doesnt, i looked at the ecm pinout log and D2 pin should have + battery voltage and it doesnt at 170 degrees. I have an 85 hot air and i am installing dual electric fans and want to let the ecm control fans, i have converted to 86-87 ecm. any ideas?
85 gn converted to 87. coil, module, ECM, intake with rjc plate, and throttle body swap. 270extreme front mount IC, 38psi injectors, adjustible FP, upgraded stock turbo, razors alky kit, TT chip, dual electric fans, fuel hot wire.

You won't see positive voltage at that pin. It's supposed to go to ground to energize the relay.
The only pin that goes positive is the fuel pump relay drive.
