MS install so far with pics.

[selmerguy]

I started my ms install today and just did some basic stuff. Here are some pics of what I have done. Keep in mind that I am doing this install with the intent of being able to go bact to the stock ecu with ease. I didn't want to drill and tap anything.

I started by installing the 2 sensors that you must use with Ms(Intake temp and water temp). I teed the water temp with little trouble. I think that being teed wont effect the temp readings too much. For the intake temp sensor I wanted to make sure it got good flow. What I did was unscrewed the three prong tap for the vacuum and put the new sensor there. I then took out the stock intake temp sensor and made a tee for that and the vacuum port. I figure that after I have the ms running fuel and spark the stocker wont be doing much. Even if it does it will get close to perfect readings anyway. Then I loomed up my ms harness and fed it through the stearing column gromet. I installed the power with a 20 amp fuse to one of the wires for the isd relay. I installed the ground to the factory ground.

Then I had to install the lines for the new afpr that should have came yesterday.(damn ups) This was not to much trouble and is pretty selfexplanitory. I was hoping that the fittings for the stock fuel filter assymbly were npt. But alas they wernt so I had to do the ruber hose with hose clamps trick. Had to delete the pics for my write up.

Pics of the ms. Wonder where all those wires go

Sam I am a little concerned about the sensor being so close to the manifold. Can you reconfigure the "T" so that one sensor points forward and the second sensor points towards the belts?

I thought about that too. I will change that today.

Looking good, otherwise. One of these months, I'll finally finish my install. I know the MS is around the garage somewhere....

/looks around garage...

Nice, good to see some pics of the install for future reference

I will do a full write up when I am finished. Also I will try to help with the basic programing for the ms. Terry has helped me out so much hopefully I can start helping people too.

Got the car running today. The aeromotive came in and was easy to finish up. I am still using the stock ecu for fuel and spark right now till I get used to the msns. Will post pics soon.

What injectors are you using?

 

[selmerguy]

What injectors are you using?

Stock as of now. Terry sent me an extra injector harness wit pigtail. Only looking at it I thought it was the same harness that was on my car. Turns out, it's different so instead of taking out my injector harness twice (once for the ms and again for swaping injectors). I will wait for my 450's to get here to do all that. This will also give me more time to play with ms. Megatune has got me trippin' right now. It's still cool to see everything going on in real time and to be able to log.

Here is a pic of the aeromotive.

I got ms all wired in untill my injectors get here. I really wanted to mess with the stock injectors before I go to the big ones. I cant really get to the injector harness without removing the rail. No sense in doing that twice in a week. Here is a pic of my car pc running megatune and monitoring my vitals.

gettin there

...do you not have injectors on order yet?


EDIT: I just happen to have a brand new set of Ford Racing green top 42#'s

(Thinks about flippin' the bird.....) My dsm 450s should be here in the next couple of days. I just have to figure out what numbers to put in for the injector characteristics on ms. The 450s are low impedance and wont work right at my current settings. Terry sent me 2 maps one was his for his 550 high impedance and the other was dougs 780's. After looking at the numbers I think dougs are low impedance injectors. I will play with it. I also found someone on 2gnt running ms with the same injectors. I sent him a pm to try and get those numbers. I still need to read more to completely understand and mantain all this stuff. So waiting a few days for my injectors is no big deal. If they come tomorrow I might have to dive in though

 

[XMasta19]

Terry told me the other day that all you gotta do is just change the injector characteristics from saturated to peak and hold since you're using low impedance injectors. You thought about flippin the bird at me huh

See: http://www.megasquirt.info/index.html

"setting the constants" and "setting the PWM"

That should clear that up and make it pretty clear for you both.

I started reading that a few months ago, guess I never finished it hahaha...good chit

Im new to the engine management world. I am currently just using a SFMU. Im very interested in switching to MS and have a few questions for you.

1. Which MS are you using ? IE MS-1 or MS-2, MSnS
2. PCB or EFI?
3. Which additional things are needed in conjunction with just a basic MS setup. ex: Aeromotive 1:1

Sure is great to have a Engine-Management forum for us N/T's
I was wondering if you could inform me on what I need to get (pre-installation stages) for MS. Thanks for any help. Figured this would be a good thread to ask in. I just want to get caught up to your first post since I know absotutely nothing about it.

Selmerguy - I look forward to a how-to write-up when you're setup is finished

 

[VelocitàPaola]

Read this thread, Terry answered pretty much all of those questions in it...

I am running the 3.0 board. I think it is ms-1. I have heard that ms-2 wont work for our cars that well. If you ask terry to build one his price and service is tuff to beat. All you need is a aeromotive and the basic megasquirt and you will be good. If you have a sfmu now you allready have the lines ran and should be good there.

The only pre-instalation stage for you would be to have a laptop ready to go. I just decided to put a computer in my car and not worrie about the laptop

Question 2....I am wondering where that question comes from. Perhaps from reading around. EFI and i am sure you will realize that EFI=Electronic Fuel injection and PCB can mean a few different things. PCB stands for "Printed Circuit Board" and it can also stand for "Poly-Chlorinated Bipheyles." In this discussion we are obviously using printed circuit board. Niether of these two terms is an option in the MS. The MS is an EFI system and is constructed on a PCB.

I replied to your PM. You need the following things:

MS CPU
Harness for MS to car
Comm cable
Laptop
Sensors
Injector/sensor plugs ect
1:1 regulator
Injectors
Fuel lines

Obviously the Fuel system I dont supply because every person will decide how they want to run the fuel system differently and the prices I pay would be the same for you plus shipping so why waste money on shipping.

The MS will require some reading on your part. I can answer many if not all your MS questions but if you read the tunign manual you will have less questions and have a better understanding when we discuss your questions here.

Although I have no issue with phone calls, I would like some of the questions posted to help others when they have the same questions. Remember, asking questions here, builds on the information available here!

Hey Terry.

I am interested in a Megasquirt for my 1992 3.0 SOHC Mitsu (3.0) (daytona) and my 1995 2.4L Nissan 240SX. If you have a e-mail address of phone # you would like these questions addressed to please PM me the address and I will be glad to do so... I guess I am confused at the difference between the boxes.... MS1 MS1 MS_N etc....

Thanks,
Travis

Travis, send me a pm for anyting off topic like that. Lets keep each post on topic so the moderators dont find that the subforum was a waste of change.

Thanks

I havent updated this thread in awhile cause I was waiting on injectors but they got here yesterday and I got them in and am having a hard time with the msns. I got the car to idle(poorly) today but now it wont start. Seems to be very lean. With the car idleing I tried to richen it up in the ve table but that did nothing. Will keep you posted.
