[RESOLVED] big 16g gm maf and translator tuning

[akira235]

thats basically all i have that will be upgraded over stock once i get the car running, both by accident, the 16g i bought thinking it was a 14b and the gm maf and translator were included when i bought the car. oh, and i have a rewired fuel pump

my question is this, i read somewhere that the translator can be used to adjust fuel ratios for bigger injectors, which would lead me to believe that i could use bigger injectors and turn the boost up and make a little more power with out having to get an safc or a wideband or dsmlink. i'll be getting a logger soon so thats covered. am i making solid assumptions here? or am i setting myself up for failure?

also, with the translator will I be able to avoid fuel cut?

You can use the MAFT as a handicap "tuning tool" for bigger injectors. It may "loosen" the fuel cut a littel but will not eliminate it. If you only have a rewired pump you'll be out of pump at 16 psi or more on that big 16g turbo.

The maft seems to work pretty effectively up to 650cc but it hides airflow like an safc so your timing will begin to get very high at some point. Definitely get the logger before you do any boost increases. Plus as said above your stock pump is going to limit you to about 16psi. With some 650s and a bigger pump, it will let you run quite a bit more boost. I would recommend the wideband as well. Do some research because there are quite a few tuning options for dsm.
