hey everybody welcome back my name is Justin and you know what time it is
ACE header installation time we're finally going to get this bad boy
installed on the car we're gonna understand our RevWorks header install
the ACE header then we're going to go ahead and flash the car with the new
base tune from delicious tuning and do a little bit of data logging so let's not
waste any more time we're gonna get started
all right we have the refworks header out of the car before we put the ace
header back into the BRZ we're going to take a closer look at the differences of
the unequal length header versus the ace a 350 equal length header that we're
going to be putting on the car now so the first thing you notice in the design
on the rev works unequal length header this tube section is a lot shorter than
the ace a350 you'll notice we have a lot more piping that comes around here
versus this one you can see there's a huge gap here between the two pipes on
the left side and the pipes on the right hand side of the engine and this is
where the equal length feature or the equal length configuration comes into
play obviously with an equal length header we have equal length tubing on
this side as we do on this side that's why this one is a lot longer coming back
into the merge collector area over here and then again the unequal length
display is the opposite we've got shorter piping on this side versus a
longer pipe on this side
now as we take a look at the over pipe and merge collector differences this is
where the ACE a350 significantly differs from a typical header like this Rev
Works header where we have a single pipe going into the over pipe so you've got
one pipe here single pipe over pipe this is the parent over pipe and then as
we've seen in the past the ACE a350 has the four pipes into two pipes which is
the submerged collector here continues in the over pipe configuration into the
final one pipe which is what will attach to our high flow catalytic converter mid
pipe
all right now that we have that squared away let's go ahead and get this thing
on the car one of the first optional steps actually
is installing these little bolts into the emerg collector pipe itself these
are what will go through the header pipe which will then be secured down with the
little nuts that come with the kit as well
all right we now have the ace a350 header installed it turned out to be a
little bit more tricky than I had anticipated and that is mostly because
of the merge collector design that this header has we of course had to raise the
engine up by removing the motor mount bolts get that higher in the air so the
merge collector would fit up under the subframe and then the next tricky part
was actually getting that connected the merge collector pipe connected to the
header itself those little bitty bolts that stick out of it that we inserted
earlier we actually had to remove again so that we could line up the collector
pipe here with the header pipe itself then we just slid those bolts back
through the pipes and then added the nuts onto the back to tighten everything
up of course with the gaskets installed as well so before we go ahead and button
everything up and reflash the car so we can start it up for the first time I'll
take you underneath to show you what it looks like with everything installed
well sadly my GoPro ran out of batteries as we were putting things back together
under the car but no big deal nothing important anyways we have the
car back down on the ground we're gonna grab my laptop my ECU tech kit
we're gonna go flash the car and then start it up for the first time and see
what it sounds like
all right so we're ready to program the car this is gonna be a little bit tricky
for me because it's dark in here it's getting dark outside well we've got
everything hooked up to the laptop into the car we have our delicious bass tune
loaded up now what the process is with this is once you flash the car you
actually have to let it idle for like 15 minutes and then take it for a drive out
on the road just casual everyday driving no wide open throttle pulls or anything
like that this is so the tuner can then take those data logs look over the data
for just basic driving and idle to make sure all of the numbers and values look
in check when it comes to air fuel and spark timing and those things once that
part is done they actually start fine-tuning the tune for power and then
we'll go back and do wide open throttle pulls in third gear while data logging
send that back to the tuner and then we kind of just go in a process back and
forth sending data logs sending a new program to flash the car with and vice
versa all right let's get started shall we
we'll turn the ignition on tell the software to detect the vehicle until
we're gonna program the engine ECU
gonna hit the query ECU button just to see what is on there of course we have
our previous ECU tech program so we're gonna go and put a note in here or
comments delicious oh one and we do have the ROM file loaded delicious ace 91 93
octane we're using the 91 octane of course we can go ahead and hit the
program ECU button it's going to go through some gibberish on the screen
once it starts programming the cool thing is it actually shows it on the
tachometer there so that's kind of your progress of the tuning process
and just about done it only takes a couple minutes or so
software is telling me to switch ignition off
hit the button switch ignition on and waits it asks if you want to clear all
or any engine codes that might be on the engine which there are none but we
always hit clear codes anyways just to clear out the ECU programming is
complete alright now that the reflash is complete I'm actually gonna back the car
out a little bit into the driveway because if you guys remember when I
started my FRS the very first time a couple years back when it had a ceramic
coated header like the ACE a 350 header is once the header started warming up
due to the engine heat it started smoking like crazy so I'm going to try
to avoid that happening inside my garage this time so we're gonna back it out
I'll put a camera on the exhaust and probably a camera on the engine bay as
well so we can see what things look like and sound like for the first start up
with the ACE 8350 header all right hanging out in the dark here we're gonna
try to get this going got to make sure we get the laptop set up for the data
logging again like I mentioned we have to do 15 minutes of idle data logging so
I'm going to turn this on on the laptop down here
alright data logging has been started go ahead and start up the car
all right so it started that is good good news first start with the delicious
tuna an ace a 350 header again I'm gonna let this sit for 15 minutes it is uh
just turned 6 o'clock we'll let this go and in the meantime while bring you some
of the footage from the startup on the outside and actually I need to check the
front and make sure we have no smoke coming out up from the engine bay which
it looks alright right now but of course the header is not heated up just yet
check back with you in just a few minutes
all right so the car has been going through its idle process here for a
little while now no smoke coming out of the engine bay so that is a plus the CSG
ceramic coating is doing its job we're gonna let the car go through its idle of
data logging and then we gotta take it out on the street for a couple minutes
and data log a little bit of that as well now unfortunately I can't really
bring you any street video today because the video that we have to do on the
streets is just general cruising no wide-open throttle pulls just yet so
we'll get that in future videos here coming real soon all right everybody
we're gonna wrap this one up the installation of the ace 8 350 header on
my BRZ is complete we have the delicious base tune on there I've got the data
logs I can send off to the tuners now it won't be long before we can actually get
the car dialed in for the ACE header and the delicious tune once we have that
complete you know what comes next it's dyno time I already have the
baseline dinos from the previous configuration take it of the car so we
have that footage as well as the power numbers so now it's only a matter of
time probably a couple of weeks or so and we'll have this guy back on the dyno
to see what kind of power we're making with that ace a 350 header compared to
our rev works unequal length header and the setup that we had before if you have
any thoughts or comments please leave them down below like always I would love
to hear from you stick around don't miss a video because you know we've got more
coming up for this guy thanks everybody again for watching I really appreciate
it and remember stay fast out there I'm
checking out we talk to you all next time
