I finally started installing my MS3 box I purchased over 6 months ago. I got the kit from DIYautotune that requires you to solder and assemble the whole thing.

http://www.diyautotu...case-p-419.html (except I got the silver case)

A quick pic from when I soldered it a while back.



I am using all stock sensors for now. IAT will be the outside temp sensor. M4.4 has a stock barometric sensor, so I am using that. Crank, Cam will be all stock sensors. I will most likely change them to the more common GM sensors. I just want to know if its possible to get it running on all stock hardware. Possibly do a PNP kit... .

For now I am staying with the distributor. When I have it running and I'm happy with the way MS3 works then I will switch to COP.

I asked s_moneh for his config file, even though he is running MS2E it gave me something to compare my settings to. Props and a big thanks goes out to him.

This how the car sits right now.



All the paper work needed to wire it.


I will update this thread as I get the car running and post some of the configs to help others.

good stuff.

No need to change out the crank and cam sensor, stock are perfectly good high quality sensors and will work perfectly fine with ms.
Your planning on using the stock baro sensor as your map sensor? Im pretty sure that is just an atmosphere baro sensor so im not sure if it will compute boost...but i may be wrong.

your ditching the maf and running speed density correct?

btw i ms2ed my 850 and andrij (s_moneh) bought my old setup so feel free to pm me if you have any questions

The main thing that sucks is that you cant drive the stock temp gauage on the cluster....unless ms3 has the capability to output a frequency signal from its temp readings, but i doubt it can although you could build a seperate circuit to convert the resistance from the temp sensor into the approriate scale of frequency for the gauge to read properly.

I will be using the built in MAP sensor from MS for the MAP readings. Using the stock sensor for atmospheric readings only. MAF will be ditched for sure. I still have to pass emissions so I want to be able to convert back quickly. I will see if Luckys idea will work out (see thread in the performance section).

Yeah, I remember reading that you sold it to him. I am hoping to have it running tomorrow. You didn't run sequential did you? The config i got from Andrij does not look like it. How do you think MS compares to VEMS?

Not sure what I am doing with the gauges yet. Primary focus right now is to get it running. Thanks to MS3X I got quite a few outputs to work with.

Ah duh, forgot about the built in map sensor, im used to the vems =p
ms2 was not capable of running sequential fuel, so i ran batch fire, one of the main reasons i swapped to the vems.
I love the vems, i think it is miles ahead of megasquirt, although i dont have any experience with ms3 it still has its quirks that i definetly do not miss (tin can box and old style connectors), they may seem like not a big deal but after playing with it for a while i just had enough of it, if they would just make a decent harness plug connector for it i would be happy =p
I didnt have any complaints with tunerstudio that the ms used, i like it, but the vems has its own software that is now quite good and i got used to it very quick.
The vems also has the ability to set all of its outputs on the software where as with the megasquirt most of the outputs had to be wired to the correct pin. Although ms3 could have resolved this.
Vems also has wheel speed input which i liked and a built in wideband controller and an egt input that both worked great

Im glad i swapped over to the vems, but at the time ms3 wasnt released, cant really say if i would have went that route instead but i am glad i didnt.

What do you think of it so far?
Regardless, its miles better than motronic, and none the less is a full standalone system that is as capable as the person using it, the fastest my 855 ever was was running on ms2extra =]
Also one of the best things about both systems is the open source development, thank god for very smart people willing to help others for free

[s_moneh]

Robbies got it down with the answers i'll just keep posted and see how this goes

[gilber33]

So, when you use MS, do you basically ditch the factory harness in place for a harness that you essentially make yourself that uses the factory sensors? Do you still retain all of the factory relays and fuses?

Justus made his plug and play so he could swap back for OBDII compliance. No ditching of harness.

MS3 coupled with MS3X (extension board) will give you plenty extra I/O (PWM too). You don't need to mess around on the actual board anymore. Outputs are defined or MS3X ones can be software controlled/switched. Downside is that it does not come with a wideband, but who doesn't have a wideband and thinks to install a standalone EMS.

I actually registered TunerStudio and it has some really nice features. Live tuning/analyzer...


EDIT: The alu housing is not that bad. Pretty solid actually. The DB37 connector are a PAIN to work with and try getting a housing that will fit all the wiring (rec 20/22awg). I hope they will change it with the next release. I understand they kept it so people can easily upgrade.

I like it so far. Not as hard to configure as I thought. Some of the manuals cover our stuff (5cyl and polled cam sensor) only briefly. There is plenty of infor for regualar 4 or 6 cyl setups. Joe (550) has a MS1E+S set up that was kind of a pain. MS has come a long way with the newest version.

Yaaaa man. Look the third pic from the bottom. I am using an old ECU connector (and housing) to make my DB37 adapter.

I kept my stock ECU in the car to feed the dash. I kept the stock ECT in the stock location and used a secondary ECT for Nira. There is a spot on the back side of the head that threads into a water passage. Speedo was still running off the stock ECU/ABS. I had been feeding the tach from Nira but it's only setup to output for a 4cyl so it was off slightly. I ended up splicing the crank sensor to the stock ECU and to Nira and just letting the stock ECU feed the tach. Once the stock ECU got the RPM signal again, I rewired it to control the two speed fan, freeing up one of my AUX outputs from Nira. While this might not work for those wanting to ditch the stock ECU completely, it's an option for those wanting to keep it and may make it easier to swap back to the stock ECU for emissions etc..

Thx.

Once I get the car running I will look into wiring up parts of the dash. MS3 does have an output for tach and I have it wired up, but I honestly didn't even check to see if it worked.

Is the fuel gauge wired directly to the tank sensor or does it go through the ECU as well?

[s_moneh]

fuel gauge has its own thing. Doesnt run through the ecu harness

[fischmama]

It runs!!!



The trigger for the fuel pump relay seems to be a bit weird. I changed it to a regular relay. Works so far.

I'm going to work on it a bit more this weekend and document some of the wiring. Now I need to see where to mount the box and probably make a new harness.

[s_moneh]

damnnn runs so smooth, mines kinda rough

u use lots of my settings in your tune?

can u by any chance get a video of the car starting up? i want to compare it to mine with the VR conditioner

Unfortunately its not much help since you are not running sequential but I did compare your ignition settings to mine and borrowed a couple of settings.

I'll take a video of it starting tomorrow or saturday.

as long as it helped a little bit it still counts sick u have a running ms3'd volvo now.

ok thanks! i'll wait for whenever it gets up!

quick question about your dashboard, is that a custom MS3 dash in tuner studio? i'm kinda liking that one

Yes, I have the registered version of Tunderstudio, so I added some gauges to get it running.

[mdlimy]

good job

are you using an iacv?

Sweet setup, I've been tempted for a while now to make the leap... done a few cars with MS1 and MS2, and really want to try out the new features that MS3 has to offer.

Borrowed from Hussein's thread,



Signal #B27. As you can see it uses 42Hz.

Thx, I'm pretty stocked I got it running that quickly.

Yes, but I unplugged it because it is not configured yet. Stock IAC.

I'll tell you this, its a hell of a lot easier getting MS3 to work on the S70 then the MS1 on Joes (550) 242.

I don't think I will be able to do this with MS unless I change some wiring under the relay box or make a seperate circuit for this. Does any one see any issues with leaving it a regular style relay? How did you guys deal with this?
