I've been asked
At least 10 times
How to install this
Ecumaster
Digital Ecu Tuner
Det3+
Model
I will show you
The basic installation
I have the Ecumaster
In engine bay
Here
Here you can see it
All right
The reason is
I had ignition problems with
Longer wiring
These wires
I moved it to engine bay
There was too much interference
The ignition started misfiring
With warm engine for some reason
Okay, let's take a closer look
So
There is..
Kind of
Cold weather
Not optimal
For this but
It doesn't matter
So first there's
Power +12v (pin1) and ground - (pin11)
Wires
Those goes
Here
Here's the ground wire
And here
In fuse box is power wire (ignition on)
Then there is
Ignition with shielded wires
Here, these goes to
Crackshaft position sensor (VR type, blue or red wire)
So
Ignition in (pin9) and ignition out (pin5)
In and out of Ecumaster
So there was the ignition
Then
To map sensor, these two
These are
Analog in (pin13) and analog out (pin17) (wire has to be cut between those)
Next
There is
USB cable going inside the car
And then
There is
Built in
Map sensor in Ecumaster
This hose
Goes there
It's that simple
Indeed
This
Crackshaft position sensor
Correct wire colour is blue or red
I had blue, some have red
It depends
And this
Map sensor
As you can see
Correct
Wire is the furthest one
Brown color
Furthest one
Light brown
Installation is so simple
It will be much harder with
Fuel implant mode
But it works great without
Next I will show you
How to
Use it
After installation
Of Ecumaster Det3+
There is
Pins for 20 wires
But used only
Few
There's much
Fancy things you can use
But I don't need them now
Okay
I will show you next
What to do with
Tablet
Okay, first we connect the usb
And open the DET3 Client
This one
Okay
Now it should look like this when opened
But not necessarily
If your settings
Aren't right
Let's continue, there's scope on tools menu
There you can see if you have problems
With ignition
You can test it out here
But we have everything working as you can see
Syncronised
Here
Ignition is working, connected and
Syncronised
So everything working
Okay
Car is idling with normal temperature
Air/fuel ratio is there when idling
I will fix it first
I select the whole fuel map
ECU's auto mixture adjustment
Is so powerful
So
I can adjust the non boost map
Based on idle air/fuel ratio
So I selected the whole map
And I press minus to lean the mixture
Like this
Let's check what happens
I'm pressing the minus button
Minus
Minus
More minus
Okay, mixture
Is good now
When idling
It's okay now, I wanted to correct it
First
So it idles properly
Okay, let's take a closer look
Setup menu
So
Setup tables, we have analog 1 and analog 2
Ecumaster modifies Analog 1 signal
That's my cars
Map sensor
Load
Is Ecumasters built in map sensor
You saw the boost hose
That's all we need, we use that fuel table
Ok, let's see what's next
Okay
Analog inputs configuration
You have to decide
The max values
Here's what I have
This Analog 1 is premade
In Scales configuration
This was the nearest one to my original sensor
Mixture adjustment works nicely
With this
Premade map configuration
Analog 2 is
Ecumasters built in map sensor
1 is original map
Okay
Next
Analog output configuration, this is
what
Ecumaster
After modification
Sends to ECU
From 0v to
4.94V
I had problem with 5v
It made
Error code
So I had to limit the voltage
And maybe I even broke one map sensor because of that
Okay
(Forgot to show scales configuration)
Is there anything else, yes Ignition configuration
Very important
So you must have right mode selected
Mine is 60
-2
There's 58 toothed wheel
In mine
On crankshaft
Wheel
This is the right one for me
Crackshaft position sensor type is VR
This all must be corrent to get the ignition working
Maximum rpm on fuel map
7000rpm and here's how much you can adjust
Ignition
Okay
Nothing special
Is there anything else
Okay, that's all
Next I will adjust the mixture
Idle is already adjusted
idles much better than before
With 50% bigger injectors
I have to adjust the whole fuel map leaner
Or the car will choke
Not drivable
Now for test drive
here you can see
the specific cell moving
Okay
Next test drive and
We will see how much I need to modify the fuel table
Only
A short trip
For drivable fuel map
So here it was
We will continue shortly
Okay I made
Some corrections
Drived
About 20km
Now it looks like this (AFR no boost 14.5-15, with boost 12-12.5)
Now it's drivable
So next
Idle is
Good
ECU made some corrections
Okay
Then
File
Make maps permanent
Okay
No need to
Turn
The engine off
It's only recommendation
Okay all good, saved
It's done
That's it
Car is drivable
And the fuel map looks like that
You can minimize
The correction
Level
This how
You drive
Without first lambda
Now you have solid lambda value
So you can adjust the non boost area
Much better
Where I have -30
You can adjust it closer to what ECU wants to see
ECU adjusts the mixture
To 14.7
So you can adjust this area
Closer what ECU wants to see
When you disconnect the first lambda
First warm up the engine
Then disconnect the first lambda
Next adjust the air/fuel ratio
And the fluctuation minimizes
Another thing
Reset the ECU, it also helps
ECU decides the tolerances
For current setup
It also helps a lot
With the fluctuation
It finds closer tolerances
Okay
This is the Ecumaster Det3+
Very good
For my use
You can see that I have a bit too large injectors
Whole fuel map on minus
There might be some +
A bit more boost in here
With high revs
About there
On minus side elsewhere
So I could get away with smaller fuel injectors
Current injectors are from Ford KA
Small turbo engine
Should be enough for 150hp
Okay
That's enough
