Hey everyone, Can anyone tell me if a sct tuner can permanently turn OD off for performance reasons. I have recently had my foward clutch rebuilt new OD band, red eagle clutches and still have a OD light flashing when I'm on the interstate. It has been tuned with SCT software

No it must shift at 129 mph. The speed driver reaches 5 volts. Darrin knows work arounds.

There is a speedo frappe driver that can fool the pcm with lower output. Use a gps speedo on the dash. Tune it for shifting with the fake speed

I don't understand how that can trigger a OD light . This is a street car not a 1/4 mile car who drives at 129mph ? My tuner says he didn't program it like that
