Well im currently trying to tackle some other issues on the car but i figured while at home i could work on some tune issues...
Looking at data logs from a wot run im seeing low voltage from my HEGO's
IIRC this means im running lean..
My Wideband also reads lean...
HOWEVER i failed inspection for having my HC's 8 times the limit...
This leads me to believe im running rich... Very Very Rich... so rich that im shooting unburnt fuel in to my exhaust and im reading lean.
SO in order to start to tune this thing i need guidance.... First im told to get my Maf transfer for my 24lb pro m maf.
Done.
If you are gonna run 24's ... I would upload the j4j1 file and you will get
a BUNCH OF STUFF good to go with one easy quick upload
Ive also uploaded the 24lb injector template.
I don't know what this means
And pulse width for long tubes.
I loaded in all kinds of different date here
Honestly ... I never could see any of it made a diff I could see
Now i was told to "remap the LAMSE table for OL startup and OL stabilized"
I can't say I can relate to what you are saying
BUT
See below
How do i go about doing that? I want to pull 5%-10% fuel to test my theory stated above. I also need to know how to do that...
Thanks,
Adam
Adam ... Let me get you started with some VERY BASIC info about fuel
and WOT tuning that worked for me
First we will assume all mechanical stuff is all good to go such as ........
no vaccum leaks
no exhaust leaks
all electrical connections OK
and the like
Next you wanna get your maf transfer all good to go
Next I would tell you to work on the Closed Loop part of your tune
This part of the tune is all about ............
low load driving conditions which I would break down to 3 parts
1) idle
2) cruise
3) Very ... one more time ... V E R Y ... light acceleration conditions
You should be able to get stable K's by adjusting inj data such as
low/high slope
timing table
breakpoint
offset
For a stable idle you'll want to take a look at
idle speed
isc settings
tb airflow rate
neutral idle airflow
maf transfer points at idle voltage and 1 point below and above
Get to know the point of your maf transfer curve (maf voltage can help
you relate to this as well) where below that point is Closed Loop and
above that point is Open Loop
You will use the top part of the curve as your Open Loop part or if you
prefer WOT part of your tune
Here is where I believe someone told you to remap things
In a nutshell here is how I did it
You wanna go to the fuel table that is used for WOT
As a a starting point work with the top (highest load) 2 rows
Make em fat ...
by the way ... When doing WOT fuel tuning you want
BIG FUEL ... little spark :Word:
You wanna dial back your spark a good bit here
anyway
Make your values fat like 12.25 to 1.00
The idea here is gonna be to make your fuel table and your wb match
that way
You just chnage the table values and you'll know what to expect
Once this is done ... Your wb pretty muchly becomes obsolete
I'd tell you to split the upper part of this curve in two parts
the speed gets quite high as you go higher in the curve
More importantly
You wanna know you are ... ROCK SOLID ... on your understanding
of what you are doing here so you know for sure a tweec in one
directon or the other is gonna make you fatter or leaner :Word:
Just start at the first point in the curve that is OL or WOT and tune to like
whatever is around say 60 mph or so
You adjust the points to get closer to a wb output of 12.25 AFR
Your wb does output to your dlogs
... Correct ???
Well ... That ought to get you thinking about things
The info is quite general but we got to start somewhere
Think about the concept here
and
Let me know if it makes sense
I will try to splain it better if needed
or
Fill in the blanks that I left out
306, Keith Black Flat Top Pistons, TFS/KPI HiPorts, Wolverine 1190 Cam, TFS Track Heat, 1 3/4'' Accufab Headers, 70MM Accufab TB, 24lb Injectors, 24lb Pro M maf, Innovate LC1, Moates QH, BE, EECA
Grady these values are from a stock tune with a 24lb pro m maf.
In order to start tuning i know i need to force open loop.
Thanks in advance for the help!
Why would you wanna do that
