Title: Need help swapping Maf Bosch to hitachi Post by: Merculeus on January 07, 2015, 02:12:27 PM Hello, i'm a bit new to the tuning game,i've tried to search information and i'm still not sure.I got a tune ecm and it's working with a bosch Maf sensor,i want to change to an hitachi.The housing stay the same.I would have to change the MLOFS but what else would i have to change? Do i have to change MLHFM even if the diamater doesnt change?what about KFKHFM?
Thanks Title: Re: Need help swapping Maf Bosch to hitachi Post by: ddillenger on January 07, 2015, 02:19:05 PM MLHFM and MLOFS must be changed for sure.
KFKHFM should be changed as well assuming it's a bosch--->hitachi S4 swap. Title: Re: Need help swapping Maf Bosch to hitachi Post by: Merculeus on January 07, 2015, 02:26:15 PM Alright thanks for the quick answer, I will work on that right now.
