LB7: Boost with EFI

[ctodd36]

Hey guys as you all know the stock MAF sensor quits reading at 38 psi. What are you all doing to get a sensor wired in so EFI will log TRUE boost. Thanks in advance!

well for one, MAF isnt going to tell you boost, MAP will.

Second, you can log PISG via efi live and not just PSIA like you are probably seeing, its just maxed at 22-24psi.

if you want more, search on here for the higher pressure honeywell sensor that can be wired in. you will need to rescale some tables to make it read correctly

Yes. Map sensor, my bad! Had a 4 day stint on a cruise ship! Ok. I wasn't sure if hypermax made something or not but thank you!
