i had saved a link a LONG time ago on how to go about converting from MAF to MAP, but now the page is deleted :facepalm:

does anyone have a walkthru on how to wire the twin mafs together and wire it to the MAP sensor?

any help is appreciated. thanks NICO :)

i had the gm 3 bar lying around so im gunna be using it since money is tight right now.

since the RB26 has 2 MAFs, which one does the 5v go to? do the MAFs 5v have to be spliced together then into the MAP sensor? this is the only part im confused about otherwise I have everything else figured out

thanks for the help
