so im about to finish my ka24det project and i'm trying to figure out if i should go blow through maf or the standard pull through and i also have a couple of questions.

my main concern is the tune. since this car is just my daily it is just getting a enthalpy rom tune for now.

q#1 do you need a different tune for blow through vs pull through maf?
q#2 what goes to the wastegate vacuum or boost?
q#3 what goes to the bov vacuum or boost?
q#4 does anyone know if enthalpy can tune for blow through ( assuming the tune is in fact different)?

thats all i can think of at the moment and im pretty sure boost goes to wastegate and vac to bov just want to make sure

thanks everyone who takes the time to read this

There is a lot of this around, it's a general ?.
But to answer your ?
q#1 do you need a different tune for blow through vs pull through
Yes you will need to retune or let tunner know about the blow through
q#2 what goes to the wastegate vacuum or boost?
Boots, the shorter the line the better. If you can get the boost signal of the Compressor it's a +.
q#3 what goes to the bov vacuum or boost?
Boost/vacuum I dont think it will matter(correct me if im wrong)
q#4 does anyone know if enthalpy can tune for blow through ( assuming the tune is in fact different)?
Yeah they can tune for blow through set up, again just let them know.
What he does here for the locals he sets up a base map you drive the car to the shop and he does a live dyno tune.

thanks.

my compressor housing is plumbed for a boost fitting so that will go to my wg.

ive talked the tuner of enthalpy a little back in the day and what we discused is a base tune, then i have it dynoed and all the afr's recorded and send him back the ecu for a retune. for a small fee. thanks for the help ill update if i have anymore questions
