MS1-Extra Basic Configuration manual

(MegaTunix version)

Only for use with the MS1 Extra code (MS1 - 68H908 based microprocessors)

By Philip Ringwood (daxtojeiro), James Murray (jsmcortina) and Ken Culver (muythaibxr)

 

Before you start your engine please read this entire manual and the Software Manual, available HERE. Take a few days to digest it or read it in small sections if it gets boring, but it will aid your install.

For other MS1 Extra Manuals please see HERE

Please Note:

All of these instructions / diagrams are to be used at your own risk, like most things there is more than one way to do the same thing, what we have tried to do is to offer a method that we have tested or that others have tested for us. No warranty expressed or implied.

Use at your own risk.

 


If you have coil packs driven directly from the ECU then ensure you do NOT have the coil packs plugged into the wiring loom whilst checking these settings if adjusting them on the vehicle!!!

The purpose of this Base Configuration Manual is to help you get an over view of what engine configurations the MS1 Extra code can control and help you achieve a base configuration file in MegaTunix that will enable you to start tuning quicker.
Please see the other MS1 Extra Manuals for more detailed information on the software settings and more info on all other features of the extra code, etc, HERE

If you purchased an MS ECU from me at ExtraEFI.co.uk then the base configuration would have been done for you, but a breif look at these settings will do you no harm.

When the ECU is upgraded/changed to another or the latest code the entire configuration file (**.data) is deleted from the memory of the microprocessor inside the MS ECU. A default configuration is written into the memory, but this most certainly will NOT be setup for your engine, so do NOT try to start your engine without ensuring youve been through the following settings and checked they are ok for your setup. In fact, if you have coil packs driven from the ECU then un plug these before turning the ignition on!! Ensure all settings are correct before you plug them back in or attempt to start the car.

If you have an old **.msq from a previous code then some or all of that can be used, but it depends on the old code's version. If upgrading from an 8x8 VE table version then only values like warmup enrichment, the after start enrichment, etc, can be transfered into the new config file via MegaTune. In order to transfer the data it is best to write the values down or to print the pages out and write them into the new file in MegaTune by hand. If you have a working 12x12 fuel or spark table these can be saved by "exporting" them in MegaTune (open the VE or Spark Table and select - file - table export) then simply "import" the table back in once the new code has been uploaded and the new version of MegaTune (new msns-extra.ini file) is running. Download the latest MS1-Extra code and MegaTune Installer from HERE. For information on loading a new firmware code to your MS ECU please see HERE.

If you have no idea what base map you have inside your ECU or if you need to start again for any reason then here is a default msq you can use, but you must then set it up for your vehicle before attempting to start the engine!!!!! You should use this manual to figure out the best settings for your configuration before attempting to start your car. For more detailed information on the software settings and all other features of the extra code please see the MS1 Extra Software Manual

If you have coil packs driven directly from the ECU then ensure you do NOT have the coil packs plugged into the wiring loom whilst checking these settings if adjusting them on the vehicle!!!

Description of terms:

MS1 Extra code is a version of firmware that has been developed by Philip Ringwood and James Murrey over the past few years. This code can be run on any version of B+G Megasquirt PCB (V1.0, 2.2 or 3.0) using the MS1 (68HC908) microprocessor. It is based on the B+G original V3.0 code and Eric Fahlgren's Dual Table (DT). It also amalgamates lots of other code versions and mods that many people have created, as well as lots of ideas and needs from people on the MSExtra forum. See HERE for a list of credits.

 

MSnS mode is for use with a single coil and distributor allowing you to control your timing if you have a single coil firing through a distributor, or an MSD 6A amplifier, firing trough a distributor, etc.
Your tach signal into the Megasquirt can come from a crank trigger or from a "locked" distributor using hall, inductive VR or opto sensors.
This mode requires ONE Trigger per Spark Event, like a set of points or the equivalent. e.g. 2 pulses from a crank on a 4cy or 4 pulses from the disrtibutor on a 4cy (distributor runs at half the speed of the crank) , 4 pulses from the crank on a V8 or 8 from the distributor on a V8, etc.
If your engine has a toothed wheel (e.g. a 60-2, 24/2, 36-1, etc) then you must NOT use MSnS mode, setup the GENERIC WHEEL MODE instead, and select SparkA as the only spark output whilst using the distributor. Please see HERE for more details on MSnS mode.

 

Generic Wheel Mode allows the use of a multi-toothed trigger wheel such as 36-1 (commonly fitted to Fords), 60-2 (used mainly by Bosch and therefore very widespread in Europe.) Custom wheels such as 6-1 or 4-1 also work. Also supported are dual wheels such as the 24/2 wheels seen on Mazdas and Toyotas. These have two wheels, one with 24 evenly spaced teeth and a second pair of teeth with a second sensor.
The code supports:

Fuel only

Single coil (distributor based setup)

Wasted spark with multiple coils

It can also support coil per plug in some installs.

For wasted spark you require a minimum of single "missing tooth" crank wheel, only engines with an even number of cylinders being supported. You need at least 4-1 for 4cyl, 6-1 for 6cyl or 8-1 for 8cyl. However, the 36-1 wheel is probably the easiest to obtain. The MS ECU can drive up to 6 seperate spark outputs, meaning it can run up to a 12 cylinder in wasted spark mode. (4cy, 6cy, 8cy 10cy and a 12cy)
Coil per plug can be achieved with a crank wheel and single-tooth cam wheel OR a dual wheel cam setup OR a missing-tooth cam-wheel alone.

Please see HERE for a more detailed description.

 

Wasted Spark is used on a lot of 4 stroke engines and is where a pair of cylinders are fired together, one cylinder is on the compression stroke and the other on the exhaust stroke. The 2 cylinders that are fired are the pair that move together and are therefore opposite each other in the firing order. This setup therefore has multiple coils, usually 2 for a 4cy, 4 for a 8cy, etc. It does NOT have a distributor, as the spark plugs in the cylinders are connected directly to the coils.

e.g.
Rover V8 firing order = 1, 8, 4, 3,  6, 5, 7, 2    This would be 2 rotations of the crank, so 720 degs.
To fire this engine in wasted spark we would fire 1+6 together (as these are opposite in the firing order), then 90deg later we would fire 8+5(again these are opposite in the firing order), then 90deg later 4+7 then finally a further 90deg we would fire 3+2, this repeats every crank revolution.

Ford 4 cylinder firing order = 1,  3,  4,  2       This would be 2 rotations of the crank, so 720 degs.
To fire this engine in wasted spark we would fire 1+4 together (as these are opposite in the firing order), then 180deg later we would fire 3+2 (again these are opposite in the firing order), this repeats every crank revolution.

The cylinder that is fired on it's exhaust stroke is know as the "wasted spark" as it produces no power. The benefits are that the coil fires less often than when using a single coil and has more time to charge ready for its next spark. This is very helpful at high revs when the charge time can be very small.

Ford EDIS: Ford's Electronic Distributorless Ignition System (EDIS) is an ignition system that does NOT require a cam position signal. It can function with just a variable reluctor crank position sensor (VR sensor) and a 36-1 tooth wheel (36-1 means '36 teeth minus one', and refers to 36 evenly spaced teeth, one of which has been removed).

Because it doesn't need a camshaft position sensor, EDIS is a particularly easy way to replace distributor ignitions when retrofitting older engines with a modern computer programmable ignition, but we now recommend directly driving the coil packs from the MS ECU using the VB921 FET's. This does away with the EDIS module, so all thats needed is the 36-1 wheel, a VR sensor and the coil packs.

See HERE for more details on the Ford EDIS mode.

 

GM HEI: There were a number of different kinds of General Motors HEI modules:

* 4 pin module - electronic ignition, but doesn't do computer timing control, top left
* 7 pin module (large) - electronic module that does timing control, used with coil-in-cap distributors, top right
* 7 pin module (small) - electronic module that does timing control, used with some external coil distributors, bottom right
* 8 pin module - electronic module that does timing control, used with most V8 external coil distributors, bottom left
* 5 pin module - rare not shown

See HERE for more details on the GM HEI Module

 

Ford TFI code is only designed for "push start" modules which are claimed to be grey in colour. Computer controlled dwell modules are black. Maybe this is USA only data because the Push Start module I used is mainly black. On a push start the START wire will run to the ignition switch. On a CCD that pin is IDM and will run to the ECU.
NOTE!!
If you are using an aftermarket spark box like MSD you must simply configure your spark type as MSnS and NOT TFI. See the MSnS settings.
When the code is set to TFI it expects you to use the TFI module to fire the coil and provide cranking spark.

ALPHA testers desired for CCD modules. Try as the settings on this page but set to dwell control instead of 50% duty.

For more info on Ford's TFI setup please see HERE

Here is the pinout of a typical dizzy mounted module, consult you workshop manual if necessary.

 

*.msq files: are files that MegaTune generates when you "save" your configuration. These can be opened by MegaTune and other MegaSquirt tuning software and hold all of the data that is stored inside the ECU thats specific to your settings. These are not used by MegaTunix, it saves files as data files.

 

Lambda Sensors Vertually all the standard sensors in modern cars are Narrow Band lambdas that give a 0-1V output. These are usually supplied with either 1, 2, 3 or 4 wires. The 3 and 4 wired sensors generally have a heater in them and these are recommended if you want to use a Narrow Band sensor as they dont rely totally on heat from the exhaust gases to get them up to operating temperature. The voltage at14.7:1 AFR (Lambda 1.0) is usually 0.5V, anything lower is lean, anything higher than 0.5 is rich. These can only be used to tell you that your lean or rich of 14.7:1, they are not accurate at any other value other than 14.7:1AFR (0.5V output)

Where as a wideband lambda sensor can tell you accurately the AFR from around 10-20:1. These usually have a voltage output range of 0-5V and some can be programed to give a straight line output with respects to the AFR. e.g. Innovates LC-1 can be st up for 0V = 10:1AFR and 5V = 20:1AFR, so 2.5V output would be 15:1AFR, etc. The WideBand Lambda sensors will need a control circuit/box to run them, the MS ECU can NOT simply plug into the sensor like a narrow band sensor.

In order for the MegaTunix software to be able to distinguse between what wideband sensor you are using, and therefore tell what the output voltage means, ????

 

 

Speed Density is where the Manifold Air Pressure is used as the load reference in the 12x12 VE table. The MS ECU has a built in MAP sensor that must be piped into the manifold, engine side of the throttle plate. As the MAP increases the fueling is increased due to the MAP value being part of the algorithm. This is especially important in a boosted engine where the increase in pressure, and therefore air, will increase the fuel pulse width for the same VE value. The default settings in MegaTune are pre-set for Speed density so no changes should be needed to set MegaTune up for this, but if you have tried another algorithm then here is how to set it back to Speed Density:

 


Alpha-N is useful for long duration cams, ITB's, etc, where the resolution of manifold air pressure (map) would be small (e.g. an idle map value of 75KPa would be too small to get a good resolution from). It is also useful to get a smoother idle on engines that have erratic map values. MegaSquirt can be converted from its default speed-density calculations to Alpha-N. You will no longer use the MAP sensor for estimating the load on the engine -- the throttle position and rpm are used instead. This can help with cams with long duration and/or a lot of overlap, as they have low and unstable vacuum at idle, making tuning very difficult. It can also be helpfull for ITB setups when atmosphere is reached very quickly under light throttle openings.

For example: On a flat part of the torque curve, going from half to ¾ throttle might not require the value to change in the VE map on speed-density if the air/fuel ratio is the same for the 2 loads as the change in MAP will do this. On the alpha-N system the map bins will be different as this is the only way the MegaSquirt can find out about the higher fuel demand.

In Alpha-N mode MS still makes 02 corrections (i.e. runs 'closed loop'), if you have it enabled.

One thing you have to always remember with alpha-N is that you don't actually know where the effective WOT is anymore (i.e., when you have enough throttle that opening it further doesn't affect the amount of air being ingested). At low RPM WOT could be only 20% throttle. It is worth setting 5-8 of the total TPS bins (load on the VE Table) to cover the first 20% - 30% of the throttle opening to make tuning easier. This will help you end up with a driveable car, as most driving on the road is done in the first 30% of the throttle. The rest of the bins can fill in the gaps between 30% and WOT. (Wide Open Throttle)

If you have a boosted engine please see Hybrid_Alpha_N below.

 

 

Hybrid_Alpha-N

With a boosted engine using Alpha_N, you MUST use the Hybrid_Alpha_N setting (in Advanced Options) with Megasquirt, because the throttle position bares little relationship to the amount of air going into the engine. Alpha-N is for naturally aspirated engines ONLY, the Hybrid Alpha-N adds the MAP value into the fueling algorithm, (obviously the map sensor will need to be connected to the inlet manifold) so fueling is increased with boost pressure.
Please Note: There is no extra table or any other settings other than selecting the option in Advanced Settings. It is simply used to add the MAP value to the equation.

To use Hybrid Alpha_N ensure you have Alpha_N selected as above (HERE) then simply set your Advanced Options - Hybrid Alpha_N mode = ON

Hybid Alpha-N =

PW = REQ_FUEL * VE * TPS * MAP * E + accel + Injector_open_time

Normal Alpha-N =

PW = REQ_FUEL * VE * TPS * E + accel + Injector_open_time

 

VR Sensor (Variable Reluctance Sensor)

Example of a Ford Variable Reluctance Sensor (VR Sensor), these are positioned so they detect the teeth on a crank wheel. When a tooth (peice of metal) passes them at high speed and at a very close proximity (0.75 - 1.0mm) they generate a small signal.

     

 

The following diagram shows what happens when the VR jumpers on the V3.0 PCB or the VR sensor is wired the incorrectly:
(VR sensor ground signal wired to pin24, the sensors signal +ve wired to the screen and the VROUTINV linked to TSEL)
or
(VR sensors +ve signal wired to pin24 , the sensors ground wired to the screen and the VROUT linked to TSEL).
The trigger points (where the signal goes through the line on the positive going slope) are shown in red. The time between the trigger points is consistant untill the missing tooth comes passed the sensor. The gap has increased a little (not fully) as the wave returns to the line but as it has to wait untill the next positively going slope the next gap is also decoded as another missing tooth.

 

This diagram shows the jumpers and te VR sensor wired correctly;
(VR sensor +ve signal wired to pin24, the sensors ground wired to the screen and the VROUTINV linked to TSEL)
or
(VR sensor ground signal wired to pin24 , the sensors +ve wired to ground and the VROUT linked to TSEL).
This time the negative side of the slope is used as the trigger edge. This means that as the missing tooth passes the sensor it doesnt trigger the ECU untill the fall from the next tooth (Tooth 1).

 

 

Original Equipment Temperature Sensors:
If you are using temperature sensors that are NOT MS SENSORS (e.g. your original equipment sensors) then you will need to generate 3 inc files so that Megatune displays them correctly. (2 inc files are generated for the Air Temperature Sensor and 1 for the Coolant Sensor)

Rotary Engine setup

2 Rotor Engines -- 3 Rotor Engines

The rotary engine is obviously fundementally different to a normal 4 stroke engine, but it can still be controlled by the MS ECU as long as a few rules are followed. With a four stroke engine, in 720° of crank rotation, it will draw in the equivalent amount of air as its rated displacement. But with a rotary engine in the same 720° it draws in twice its rated displacement.
Therefore:
If you have a 2 rotor (Mazda 13B) engine (1.3 L) it's really like a 2.6L 4 cyl 4 stroke engine.
If you have a 3 rotor (Mazda 20B) engine (2.0L) , it's really like a 4L 6 cyl 4 stroke engine.

The rotary engine has a leading and a trailing ignition (2 plugs per rotor) the leading fires first then the trailing fires a few degrees later. On a 2 rotor engine the leading can be fired in a wasted spark format, but on a 3 rotor engine the leading must be driven by 3 individual coils e.g. COP. Simply set the system up as a 6 cylinder engine running wasted spark, this will fire the 3 spark outputs (Spark A, B and C) every 360 deg of crank rotation. Please see the Rotary Trailing Setup HERE for more info before running your engine.
