4L80E Line pressures
Posted: Sat Jun 18, 2016 12:28 pm
Anyone got any input on 4L80E line pressures? Infact anyone know what the rise rate should be with throttle position?
I know the standard controller uses TPS for load, and my installation does too (the axis label is wrong). So I'm just interested to know what the standard rise rate is, is it linear with throttle position, or is 100% line pressure achieved at say 50% throttle and it's linear to there. Or does it rise exponentially with throttle position?
I set my lowest row based on the standard line pressure with a closed throttle. So I have about 75psi at 50% duty and 180psi at 100% duty (at idle speed)
