I have an AEM boost gauge which has a 5v output. Got it all hooked up and did my custom IO below. HPT is seeing vacuum dead on but I don't ever get into boost. The gauge reads boost but HP goes to close to 0, never a positve boost number.
Is this because of trying to go from negative to positive numbers? The gauge will read 30in hg to 35 psi.
Thanks for any help.
