ECM programming; fans
i swapped in an LT1 and i have the dual fans from the LT1, and the LT1 ecm and wiring harness.
Problem: i have a 160 stat. and the ecm was tuned by MADZ28. i think he put the fans at 180. however, both fans turn on before 160...which means even when i'm driving down the highway, both fans are on.
i didn't have the A/C deleted and i don't have the wires hooked up to anything...could this be the problem?
to be more percise...the low fan turns on first, then they both turn on high...before 160.
