okay at the end of the last video I had
a little bunch here of 2 6 6 7s for a
suggested turbo value for injecting 70
milligrams now what I've done is I've
altered those values that I hadn't done
before by the same percentage in other
words if that value there has dropped by
whatever percentage it's dropped by I've
made this one drop by the same
percentage and I've done the same this
side so I've done that all the way out
there and all the way down there and
I've done that using the calculators
that are build it built into Microsoft
Excel and so these figures have been
automatically changed for me by Excel I
could have sat here with a calculator
and done it but obviously that'll be
more hard work and I didn't bother
so I've done it using Excel itself to
work out those values so that's the
point at which we stopped last time and
I've just completed the whole lot if
you're not 100% sure how to do that then
really that's not something for this
because it's nothing to do remapping
it's just basic math so you'll have to
look up that for yourself or look up how
Excel does that now I did say that at
that point we would run into trouble if
we tried to use figures like that
because the boost limits would cut in
and cause us problems now the single
value boost limit is very close it's 262
hour and we're looking at two six six
seven now I don't think overall we're
probably likely to allow this in the end
because we've if you've been watching
these videos we haven't got some talk
map yet so what I'm going to do is I'm
going to guess that should we change
this value to a new value so I'll just
put in there new
let's say that we decided at some point
we'll change it to two six seventy and
we don't have to worry about that
because if we change it to two six
seventy and it's okay we will not drop
into limp mode in the car we'll be fine
if we've done a change like that and the
ECU thinks to six seventy is too low
obviously whenever the boost is running
it's going to peak over that and drop
into limp mode and we all know that we
need to up that value I suspect by the
time we finish playing with several of
these maps that's not going to be a
problem okay that brings us onto the
booze limiter now here I've got a slight
problem because of my own stupidity in
all of these videos I've been saying
that the maximum is to 350 quite how I
arrived at a figure of to 350 I don't
know because when I look at here I can
see that I've got two 350 there and I've
got two 350 here but in the middle I've
got two 400 so quite why I decided to
350 was the highest I don't know and no
one's contacted me about the videos and
pointed out that that's wrong but I
won't lose any sleep over it but so
obviously what I'm going to do is at
this moment in time I'm just going to
undo my stupid error put that back in
there is my high point but I want US
state boulders now I don't want that so
I'll put that in there as my high point
and I will make that value to 400
instead and
I can only apologize for my own
stupidity now of course here what
changes do we need to change well we
need to change things but only in line
with what we think our maximum is likely
to be so we don't really need to change
all of these values because we are
probably not in all parts of the map
going to be driving flat out so it's
possible that we won't want to change in
areas like this if we make changes in
areas like this on a sort of a global
scale we do run the risk of causing
ourselves problems but should we end up
in a part of the world where the air
pressure is very low if you don't think
that that's very likely then you could
make these changes on a percentage basis
so if we wanted to completely rebuild
this map in a different manner we can do
it like we have done with others we
could just say well okay what I'll do is
I'll put that in there and pick that
sell there so that's my air pressure
sell doesn't quite fit that I'm not
going to worry too much about that I got
a slight problem with picking up the
numbers that's probably because of
formatting so we'll go and have a look
at formatting and we'll call that a
number with no decimal points see if
that solves that one it does and then
now just drag that one down see what it
makes of that and of course again we've
got problems with formatting it's funny
how sometimes the formatting doesn't get
too uptight and other times it goes
completely daft I think I will make that
bold and that one bold so that the to
more or less match each other up right
hasn't done it has it I know why that
was because again me being silly right
bold and just clicky them at that one
bold right now what I could do is I
could decide to up the values all over
couldn't I I could just say that this
figure is that one times one point one
and see what that does done down there
and then I could say right what's that
done over there a ten percent increase
all over there's some apart from the odd
decimal point jumping up and getting in
the way he's not looking too bad
surprisingly it's got me to a maximum of
two six four oh and we were looking for
our maximum won't we have to double six
seven so we're not far off are we I mean
them if I go back and have a look what
if I was to go for one point one what
should we actually have 15% called at
1.15 what does that do to the figures
look at that I'll give me two three
lands and two pairs let's go across to
there to 760 so I don't really even need
to go that far do I am into 760 that's
higher than what we suggested on here so
now obviously you can sit down and try
and work this out but it's just as easy
in many respects to just say to yourself
well let's have another go one point
three let's see what that would give us
that down there and then I'll drag it
all the way across here and see what
that gives me two point seven one two
well that's you know that's getting very
close isn't it now I would prefer the
values on here not to be higher than
there so if I can't find a value that
I'm happy with I may go back and change
the maximum boost to make it a little
bit higher but before I consider doing
that I'll try oh not there I didn't mean
to do that let's just undo that prefer
it up here so let's try one point two so
that would give us twelve percent so try
looking at that see what that gives us
two six double eight I think we're going
to get much closer our weak without be
making really silly changes up there so
two six double eight so that's not bad I
think I can live with that and then all
I need to do is say to myself well this
is a personal preference I don't like to
see that number less than this one
I like that to be my emergency so I'm
going to put in there
a slightly higher value again now the
problem with this is that we don't
really know for sure what is a suitable
highest number here to feel safe with
that turbocharger that there are ways of
determining this and maybe if I looked
on the internet it would tell me but I
I'm sort of hanging around a fairly high
level which can be a bit of a problem
because obviously I don't want to be too
high at that point so what I'll do is
I'll try putting in there I think for
now something that's fairly close anyway
I'll go four to seven hundred and then
at least that's bigger than this one and
again remember what I've said all along
this is not exactly how you have to
remap this is not a set of professional
changes this is something that if you
are having a fiddle
around and want to know roughly what to
do it's pointing you in the right
direction it's not saying hey here's a
load of figures copy DS now taking that
point in mind I now can copy and paste
all of this into here if I want and all
my figures will be twelve percent bigger
or I can just choose to leave most of
this alone in other words I can say what
damn down around here I'm not that too
bothered about and across here I'm not
too bothered about and maybe right the
very very top I do actually like having
that much of a restriction so I'll keep
perhaps some of these values at the top
so the only values R will change is
somewhere around in the middle here so
you've got a number of choices put all
of this into here change more or less
this whole bit here so just at the top
end or just go for this sort of middle
ish region around here and again that is
entirely up to you you could try
variations on that until you get what
you think is the best for you and of
course were you having this
professionally done at a rolling road
they might well suggest that to you they
might well say right we're just going to
make some changes and then we'll see
what that's like and then we'll make
some more changes and see what that's
like if you're doing this at home
without rolling road you can't do that
because you have no yardstick so all you
can do is make some changes drive the
car and see what it's like now again all
of this you can't actually do yet
because even if you've put all this
information into the limiter and you've
changed the limit value in the map we
still haven't got our boost map finished
because all we've done is talked about
an extra column but you can't have an
extra column you need an extra column in
here which we haven't got and we haven't
finished sorting out this one the smoke
map because we are going to need new
data on the smoke map some of this but
we need to do something about
news that are on here so everything
about that is going to need a slight
change before we can even consider this
area covered so what I'm going to do is
I'm going to stop there and then the
next video I will try and tie all of
these bits together so in other words I
will try and tie the maps for boost and
the smoke map all together in one
complete package and say right that's it
I'll finish that peer so we'll do that
next time
