General Tuning Questions And Discussions
You can target 14:1 If you want the later model stuff with sequential injection does but being batch fired I stay richer to smooth out idle and they tend to rev nicer on throttle crack.as long as you get it away from 14.7 so it doesn't go into closed loop fueling at idle and surge you'll be fine. There's iac adjustments for how far from target rpm it can get before adjusting iac to compensate as well as the idle proportional spark to help stabilize idle if you have the idle spark advance set lower so it can gain torque by raising timing
If Its Got Gas Or Ass Count Me In.if it cant be fixed with a hammer you have an electrical problem
Because the OS triggers open loop mode for exactly target=14.7 AFR as that is where the narrowband should be functional to allow it. In factory tunes idle is not set to this.
