maft with eprom programmed for 2g maf and 550cc's

[ilco187]

ok i just got a maft blowthrough setup and i have a eprom burned for a 2g maf and the 550cc injectors. should i set the maft as if the injectors were stock 450's or how should i go about this, i have the oem eprom also. but i would rather keep my burned chip.

Yes, you'll 0 out the maft as if you had 450cc injectors. The chip is already pulling out the necessary fuel to compensate for the 550's.

i guess i forgot to put in there i have a gm 3 inch maf, would i still set the maft at 0.

just making sure i am giving all details but if the answer is still yes than just say yes

ok i installed it all with the eprom and it runs way better than it did with the 2g maf, and my a/f gauge dont swing like its on crack

ok so i have been doin some reading on using the maft and gm 3" with my ecu programed for my 2g maf and 550cc injectors and people say to set it at aux 4 base 2 to emulate a 2g maf signal so my chip reads it, so my question is should i set dip switch 2 on for a 2g car or leave it set for 1g to do the emulation.
