basic msns

[junkyarddsm]

so ive been looking for awhile now and have not found an what I need. were can i buy an already built and ready to install and how you tune like dose it come with the software or is that separate? How much dose it take to install it? I have basic know how

of motors but know nothing about ecu or ems any help would be sweet

You can buy them assembled from Symtech Labs

so i were to get the msns ms3 in conjunction with the ms3x board and wire harness would that be over kill for just running 8 psi of boost and basic tuning ? correct me if i an wrong but if i use msns i do not need to have an fmu or sfmu in comination with

 

[SupremeDsm]

Just get dsm link v3. ECM tuning is the manufacture and it would be the last thing you need to buy for tuning wise! Great program comes with software and a chip installs on an EPROM ecu and you tune it with your laptop. It's fairly simple to tune with.

 

[junkyarddsm]

I have the 420a im sure in all my searches not to say you are wrong but dsm link is for the 4g63 right. I may be wrong but if so please correct me.

 

[Locke]

ECMlink/DSMlink won't work on the 420a.

MS on a 8psi car isn't required, but it's not overkill. It'll give you more options.

FMU/SFMU shouldn't be used with MS; use a AFPR instead.

 

[junkyarddsm]

So if i were to run a afpr along with a walbro 255 fuel pump and 8 psi of boost i really would not need msns or would msns just help to get the little tweeks out of the system

It will run fine without MS, but again, MegaSquirt will help you play around with your tune and get the car running much better.

It'll run fine in vacuum without MS, but there won't be anything to add the extra fuel needed in boost. You would need MS in this case.

The three basic configurations are:

• Walbro 255lph HP/12:1 FMU
• Walbro 255lph/S-FMU/No stock FPR/Larger injectors
• Walbro 255lph/1:1 AFPR/No stock FPR/Larger injectors/MegaSquirt EMS

Just a quick note on terminology, "MSnS" or "MSnS-E" refers to "megasquirt'n'spark-extra", a type of firmware that doesn't exist anymore. When referring to the physical ECU, just "MegaSquirt" or "MS" is correct. The firmware it uses is either the "MS1/extra", "MS2/extra", or just the "MS3" firmware.

I am starting to get a better understanding of what i need to us MS. I really didn't know to much before this thread. I'm going to run MS before I turbo so I can have a better understanding of how to tune with MS. I'm trying to not blow my motor apart. I what it to run smooth like it dose with the factory ecu. Is MS simple to tune with? or is it like a lot of stuff you really have to know what you are doing (like programming it your self if that makes sens).

If the car isn't currently turbocharged, then you don't need to fool around with the fuel system at all just yet.

Tuning is tuning; it's not much different between different EMS systems. There's no "programming" in the strict sense of the word -- it's just setting a bunch of parameters.

Look at the links page Locke gave you earlier. It has links to all of the tuning manuals. These will walk you through how to set every parameter there is.

I know its been awhile but im finily on my way to boost. Ive been looking at MegaSquirt MS3 EMS ECU - SymTech Laboratories and im just wanting to know if I would need to buy anything else with the ecu (sensors)? I do not think I need the ms3x board. Im just looking for something to do the basic fuel. I plan on staying with the stock ecu and ms till I get the hang of how it all works.

 

[VelocitàPaola]

You might be better off with just an MS2 ECU if you just want to control fuel. It's cheaper, but still pretty powerful.

 

[junkyarddsm]

Thats funny because I was thinking the ms2 would be more of what I was looking for. I would still be able to go stand alone in the future if I wanted to correct?

 

[Locke]

Yes, you could.

If you are going to go with prebuilt MS2. I would personally suggest a 3.57 board.

MegaSquirt-II EMS System - SMD PCB3.57 - Assembled Unit DIYAutoTune.com

That unit right there.

heres why...

New Features specific to the latest PCB Version 3.57 Surface Mount PCB

90% of components converted to surface mount. This standardizes the part numbers used, as well as the assembly process, resulting in consistently high quality.
All standard ignition input settings are now easily set by jumper shunts, no need to bust out your soldering iron to change your base hardware ignition configuration anymore!
Pulse-Width Modulated (PWM) Idle Valves are now natively supported by the PCBv3.57 hardware without the need for modification. This is one of the coolest features as this was a very common modification that will no longer be needed. The circuitry on the PCBv3.57 will control a standard on/off fast idle valve, or a 2/3 wire PWM Idle valve!
Enhanced I/O Capabilities
DB15 Added for bringing signals into/out of the ECU
Common signal pickup points (IE 'top of the LEDs, etc') are brought out to easily accessible solder pads
LEDs are surface mounted

The v3.57 is electrically identical to the v3.0 board, it's just harder to modify and repair if things go wrong. That particular ECU would still need to be modified for the 420A as it does not have the correct input or output modifications.
