Switched power that stays hot while cranking?

[slowSfaux]

Like the title says, I need my switched power to stay hot while cranking so my boost gauge stays calibrated before the engine is drawing vacuum. So lug 75x won't work. I've read people using the radio for power, but that stays powered even after the key is shut off until you open the door, so I'd rather not use that.

Fuel pump

The fuel pump doesn't stay hot before cranking though. It doesn't even prime 100% of the time until you actually start cranking. I have an extremely noisy 044 pump and a fuel pressure gauge under the hood, otherwise I wouldn't have ever known.

I'm sure I'll find something, was just curious if there was a commonly used one that was well known already. I'll post my findings when I get around to fixing this.

I had to find a constant +12v when installing my meth setup. Here is a link to where I tapped my harness @ the ECU https://www.audizine.com/forum/showt...1#post12337916

Aren’t you using the awe gauge or did you get a new one? Mines hooked up to the 75x with no issues it seems.

Wb- thanks man, I will likely use that source.

Cj- my awe gets pegged at 30. I bought the aem 35psi one. So far I can't speak for its accuracy, but it certainly is fast. I always thought I was building boost and falling into vacuum faster than the awe needle could move, and this new gauge confirms that. Not that I had an issue with the speed, 30psi just isn't enough for my setup.
