Megatune

Here is the article for setting up Megatune: http://www.megamanual.com/ms2/configure.htm

First, make a new folder in the ProgramFiles/Megasquirt/ directory. Give it a unique name, aka. Turbo Grand Prix. Then go into the MS2-MicroSquirt BG 2.890 and copy the entire contents. Paste them into your new folder. Now when you start Megatune, you will see the option to select your car from the menu.

I will go ahead and give you the settings that I'm currently using.

Starting with 'Fuel Set-Up'

General
ECU Type = 1
Engine Displacement = 213 (whatever your displacement is)
Injection Timing Delay = 0
Dual Table Use = Single Table
Barometric Correction = Initial MAP Reading
X-Tau Usage = Off
Prime, ASE, WUE, Baro Tables = Two-Point
MAP Lag = 50
RPM Lag = 50
TPS Lag = 75
Lambada Lag = 60
CLT/IAT/Battery Lag = 50
Knock Lag = 80
TPS Sampling Rate = 25
MAP Sampling Rate = 25

Idle Control
Algorithm = IAC Stepper Moving
Time Step Size = 2.5
Acceleration Step Size = 0
Minimum # of steps = 1
Start Value = 160
Cranking Position = 100
Crank to Run Taper Time = 5
Hysteresis = 5.0
Cold Temp 0.0
Cold Position 120
Cold Taper 40

Spare Port Settings

If you wanted to use the FIdle output as a TCC control, and the accel LED as an indicator that the TCC is active, you would set:

* FIdle (PM2):
o Port PM2, enabled
o variable = map < threshold = 75, hysteresis = 10,
o AND
o variable = coolant > threshold = 160, hysteresis = 10,
o Power-on value = 0
o Trigger value = 0
* Accel LED (PM4):
o Port PM4, enabled
o variable = map < threshold = 75, hysteresis = 10,
o AND
o variable = coolant > threshold = 160, hysteresis = 10,
o Power-on value = 0
o Trigger value = 1

Example: Torque Converter Clutch Control

Suppose you want to engage OD (overdrive) over 50 kPa MAP, and engage the LU (torque converter lock-up) clutch at 75 kPa MAP, provided temp is over 140 and RPM is over 2000. For a torque converter clutch control (TCC) using FIdle with 3 conditions (rpm > 1500, CLT > 160, map < 75), set:

PA0 - Knk Enable:

* rpm > 1500
* coolant > 160

and

PM2 - FIdle:

* map < 75
* port0 > 63

Injector Characteristics
Injector Open Time = 1
Battery Voltage Correction = .20
PWM Current Limit = 100
PWM Time Threshold = 25.5
Injector PWM = 66

Injector Control
Use the Required Fuel button

Control Algorithm = Speed Density
Injections per cycle = 2
Injector Staging = Alternating
Engine Stroke = Four-Stroke
Number of cylinders = 6
Injector Port Type = Port Injection
Injectors = 6

Rev Limiter
Algorithm = Fuel Cut
Lower Limit = 5800
Upper Limit = 6000

AfterStart Enrichment
ASE Hot Start = Disable
ASE Cold% = 65
ASE Hot% = 25
ASE Cold Count = 320
ASE Hot Count = 150

Accel Enrichment
Low RPM = 1500
High RPM = 5000

Other Fuel
Cranking RPM = 300
Use MAP/baro tables = Use MAP only
AFR Table Fuel Calc - Seperate VE & AFR
AFR stioch volts = 0.5 <--- I use a NBo2
Prime Pulse Cold = 6.5
Prime Pulse Hot = 2
Prime Delay = 0
N2O Enrichment % = 0
Spark Retard N2O = 0

EGO Control
EGO Sensor Type = Narrow Band
NB Voltage Target = 0.5000
Ignition Events = 33
Controller step = 2
Controller Authority = 8
Active temp = 90
Active RPM = 1500
Active below TPS = 70
Active below MAP = 80

I use a NB o2. You should not enable EGO Control until after you have a working tune.
