An easy way to prevent a lean condition?? I have been thinking about how to add a few safety features to my set-up. I don’t have a wide band O2 in the car and I find that when I’m driving, I primarily watch the road. This creates a slight problem, because if I were to have a major fuel problem, there is a good chance I would melt some ****!!
I’m pretty sure that after market systems will lower the boost levels if a lean condition would occur, but would it be possible to use a hobbs switch (similar to the ones used on nitrous systems) that would provide power to my electronic boost controller. That way if my fuel pressure dropped below a certain level my EBC would cut off, that would drop my boost from 12-13 psi to 3psi??? That seems like a cheap way to add another safety feature.
What do y’all think??
Thanks,
Dave

Sounds like a good idea. An easier way is to buy a warning light that lights up when fuel pressure drops below a setpoint you like. Autometer has them. And some gauges already have a system like that.
