I have a 89 mustang with SBF 302 with GT40P heads and Vortech V1 blower at 10psi and running the ms3 gold box with tuner studio. In the idle control section I'm trying to find out what the valve mode is supposed to be set at inverted or normal for a stock IAC valve. Idle valve type is set at PWM valve 2/3 wire setup and algorithm set to open loop. Trying to get the cold and hot cranking tuned. I'm running Siemens Deka 60's and letting VE table dial itself in with auto tune. I'm also trying to find correct deadtime for injectors which is currently set to 1.00ms. Can anyone help me out thanks.
