Megasquirt 2 Official guide for FS-DE engine
Before going into detail about MS2 engine management system, I would like to introduce myself a little bit, I'm student and I've been graduated from college in electronic engineering recently, I will continue my studies in university, but this time I will be in mecanical engineering. English is my 3rd language and I still gotta alot to learn, so its perfectly normal if you find errors. Anyway, first thing first, before MSing your car, you have to ask yourself 3 questions: if you answer no on one of these questions, then you better FORGET the idea do to it yourself, and find someone who can.
- Are you ready to give your car down time?
- Do you know all the function on a basic multimeter?
- Is your car clean?
Ok lets keep going, downtime is normal, 90% of first MS2 timers failed at first start, my car was down for only one day, because I did everything correctly first time. Only problem I encountered was a corrupt firmware, and I found it out after like 3 hours of researching. Don't be scared that you ****** things up, you shouldnt, unless you do something really stupid like giving the chip a 12v on random pin and you saw sparks...
Megasquirting your car needs basic electronic skills, you need to know how to weld wires, split wires, and KNOWING your wiring harness, not by heart, but be able to identify.
The last question seems funny but when I say clean, I mean you have no garbage inside your car, on the floor, you must not GHETTO rig stuff, common sense right? Those people who think it works, and its fine, thats not enough. It must be working, and it must be clean. If you only want it to be functional and cleaness is not important, MS2 is not for you.
MS2 can be purchased online and its the least expensive standalone EMS you can get, I assembled mine, but I STRONGLY suggest you buy one pre-assembled by Pro.
I will not teach you how to solder and stuff like that, and all the part where they go, theres a guide on MS official website (http://www.megamanual.com/ms2/V3assemble.htm) If you feel skillful enough, DIY from scratch like me, but if it goes wrong, please do NOT ask me to help, I will ignore.
dkarthik wrote a detailed guide on how to assemble MS2 yourself. I attached the pdf below.
When you buy your MS2 preassembled, the seller should asks you few question about the ignition stuff and fuel injection stuff, they will assemble the ECU to make it working on your cars specification. If they are not asking, you must to tell them the following spec:
For protege 01-03 inlcuding msp
*Coil on plug 1 coil for 2 cylinders
*high impedance injectors
*VR crank sensor
The image follow is how you need to wire inside your MS2 device if you assemble it by yourself, or you can show it to seller to let him configure.
Courtesy from dkarthik:
In my case im using a coilpack , because it comes stock with 98+ 626, basically its same type of setup, wasted spark, MS2 DIY kit comes with one coil driver, you need to have 2. Ask seller to add one.
Installing into your car:
If you want to run it as full standalone, you can completely remove all the emission stuff, and even the MAF sensor. You are replacing your OEM ECU to MS2, OBD2 port will no longer be working, and the car will not pass emission.
Here's a schematic of wiring,
You need find and cut following wires, connect just like the schematic, some wires are not need to be found like the 12V+ to injectors, as stock wiring should already be like that:
4 injector wires,1-2-3-4. ECU ground them to make them squirt, MUST wire 1 & 4 as Bank 1, 2 & 3 as Bank 2. This is essential to make car run smooth.
2 TPS wires, one 5V from ECU and other is the signal from TPS
2 CrankSens wires, I guess the polarity doesnt matter.
1 Fuelpump wire, when you ground the wire FP activate.
1 CoolantT wire, this is the wire you feed to ECU to show the TEMP of coolant
1 Air IntakeT wire, same as above but for air intake temperature.
1 FAN wire, when you ground this wire, you activate your radiator fan, this is the general output wire, I remember I set one of the Step Motor Wire as fan relay command.
1 IAC wire, since I do not use IAC valve, I cant tell which wire it is, but our car uses PWM valve. which have 2 wires.
1 Oxygen sensor wires, if you have wideband then wire your WB controller to MS2, otherwise find the stock narrowband signal wire.
3 sensor wires, TPS, IAT, ECT.You ground all the sensor ground wire on the same spot, usually its already done by OEM, to PIN 18-19 on MS2. Black triangle symble.
2 coil wires, since im not running COP I cant help much on that one. Wasted spark coilpack use 2 coil drivers, one for cyl 1&4 and one for 2&3
1 Tach wires, I connected mine to one of the coil signal wire
1 ECU power ground, usually black wires
1 ECU swtching +12V power wire
*Optional: 1 launch control wire
Now you completed the wiring, make sure you fix you MS2 to the chassis or somewhere that not allowing it to move when you drive your car.
Next step is download the software and firmware that configure your MS2:
http://www.msextra.com/doc/ms2extra/
Firmware 2.1.0 is the lastest best release IMO
http://www.efianalytics.com/TunerStudio/
Tunerstudio software, I suggest you guys pay instead because you will have the extra autotune function in real time, for fuel. Wideband required.
