MSI Assembled Flashed & Tested
 

Got my MS assembled, modded, usb adapted, and flashed with the new MSnSE firmware. Works good in megatune, everything but RPM but i'm aware there are a few things that can be changed to "maybe" get that to work. Anyway, getting closer and closer but man this was one hell of a learning curve putting all this together and whatnot. Not difficult, just time consuming, brain consuming and trialing. Let me tell you one thing though, if you have to have USB, take the easy route and get the external USB adapter. I'm happy with my "internal" one but the external piece is cheaper and supposedly works great.
Currently have it flashed with MSnSE 029 and running perfect in megatune.

Next step will be to build the harness/plug for it. Hopefully my switches come in tomorrow so i can wire it up for use with my stock ECU.
So i'm pretty stoked about what I have so far and what I have awaiting in my future. Hopefully i end up not having similar problems like that of Reverants.

Oh yeah, Thanks Adam for putting up with my questions along the way, helped out a bunch.

Just in case. Does anyone see anything blatantly wrong with my board. I might have forgotten something even though it's working great in MSnSE Megatune simulation as it is right now. I'd hate to get it all together and find out i needed another jumper or something like that. I've doubled checked on my own already so it should be fine, never know.

looks good buddy, just had to make yours look better than mine didnt U!

Well so far both you guys have better looking boards then mine. I will hopefully have mine up in a day or two.

looks dont matter Adam function does i am sure yours will work better :gay: :P just kidding chad

Makes sense, you are afterall doing your work in a fucking cave in Pakastan

Look I can make an LED Moonite hence I can surely make a Megasquirt. :)

:rofl:

Hahaha yeah if anyone can build a moonlite they can definitely build a MS for sure. If I can do it then most anyone should be able to.

You scrub your boards with alcohol yet Adam?

no was out of it last night, im gonna tonite.. i was freakin out when i send u those msn messages last night, but realized it was cus i was tryin to connect to my board that had ms1 firmware on it with the megatune configured to msns so now evetything is peechykeen

looks good, but don't think you're done assembling. you'll pull that thing right back out and put in boost control as soon as you get it running.

That's what i'm talking about. For the time being I have the Tullos to control boost though. Atleast I'll already have the GM solenoid in place for later.

I scrubbed mine down with isopropyl alcohol last night, the MS and Stim. I pulled the MS chip out before I did it just in case. The megamanual said scrub it all down and then rinse it in hot water, so I did just that and let it dry all night. Need to load up a .msq and get to tweaking it to my NB.

do u have a good link that shows what mods need to be done for boost control?

Could you give us a few more details on what made it so difficult? I'm currently using the external adapter but I put a socket on the board for the RS232 so I could add the internal once everything was tested (internal board is sitting in my tool box). I'd like to know what I can do to make the install less of a pain.

Long as you socketed it then i see no problems because you can go back. I on the other hand had to cut the circuit board to get mine to work because i stupidly didn't go to radioshack and buy a damn socket. Anyway, when you cut that circuit you can't use the DB9 connector unless you rejumper it on the back side. Anyway, it's just stupid that you can't use both. If I was gonna do it again I would socket it just like you have and still use the USB adapter.

The actual wiring it up is easy though.
