CHIM Posted February 11, 2010 Share Posted February 11, 2010 (edited) MS-1 v 2.2 assembly and install on n/a block-turbo conversion We chose the MS-1 un-assembled to save a few bucks and maybe learn somthing in the process. So here is the MS-1 componets unpacked and ready for assebly, allmost overwelming at first glance but it was accully pretty easy and fun assembling in small steps. First things first you gotta have the write tools on hand and some knowlage of soldering. Here we have a very important tool, makes a great wheight to hold componets in place on the bottom of the board while soldering. The contents of this bottle help furthermore in making the project a little funner and less duanting:lol:. after alot of reading and double checking my work and about 2 hours later i have an assembled MS-1 Back side of the board showing the built in MAP sensor (no MAF to deal with under the hood YAY!) I assembled the MS-1 without the stimulator wich is NOT the recomended way to do it, During the assembly process you are asked to test the board after several steps of the process (tight budget kept us from getting the stimulator) But all came togeather well, must have done somthin' rite:banana: The Megamanual containing the assembly instructions is very descriptive and writen in easy to understand step-by-step english. This MS-1 kit is a fuel system managment only (no ignition control) so i used the 2 pole hall distributor (carb model), The MS-1 needs a extra jumper installed the recognize the hall sensor as it is not a solid on/off break but rather a wave pulse. so she's assembled and ready to install! If your planning on running a megasquirt save yourself some trouble and get the DB37 pigtail, usuing wire cut from the stock harness was a pain in the butt to solder to the VERY small pins on the DB37. (we accully choose the get the pigtail after multiple problems with the wire moving and shorting out and fryed a diode). The point to usuing a megasquirt in the first place is to have custom control over your fuel delivery and minimise unwanted or unnessisary items from the motor compartment. We removed the stock cold idle valve from the thermostat housing and used a carbed housing instead. Since we have no plans to install a AC on this vehicle we use the fast idle switch located behind the throttlebody. This switch is used by the stock system to idle the motor up to counter the extra load from using the AC, and yes it works great as a cold idle switch. The MS-1 allows you to adjust what temperature the cold idle switch engages and disenages. I had the laptop on hand during the entire install so i could test and check each item as i connected them, eliminating any probles before they they happen. I ended usuing the stock temp sensor (the one on the back of the manifold) after realizing it was compatible with the MS-1, leaving the one on the front of the manifold open for the stock temp guage. i made this inline temp sensor before i realized the stock one worked with the MS-1. (was going to be inline on the input heater hose). This is our custom intake, yes it's a exhuast 90 (remember i said we were on a budget?) Had to use a few pieces from the stock rubber tube to get a snug fit on the air filter. And here is the intake air temp sensor, When buying sensors for a megasquirt think "Chevy", alot of chevy sensors are universal and work perfect with a megasquirt! This is an open element air temp sensor, it's important to use the open element on a turbo as the intake air temp changes with the use of the turbo. The open element sensors react faster than a closed element sensor. The closed element sensor's are fine for N/A motors as they do not heat up and cool down constantly. The MS-1 also allows you to easily calibrate your TPS as well, no worries if you have removed it and it's not set anymore, a few simple slicks and your TPS can be set to the MS1. Here are a few screen shots of tuner studio and the setup were running on this car. I do have the saved file that can be directly uploaded the the megasquirt ECU wich will set everything you see here if anyone wants it. throw it all togeather and....... SHE RUNS! Of course you want proof! Next project: MS-2 v 3.57 on EJ-22 turbo RX conversion! Edited February 13, 2010 by CHIM Quote Link to comment Share on other sites More sharing options...
wagaru Posted February 11, 2010 Share Posted February 11, 2010 nice! have you had a chance to drive it yet?? Quote Link to comment Share on other sites More sharing options...
eulogious Posted February 11, 2010 Share Posted February 11, 2010 This is sweet! Good work! I am planning on running of these in my MR2 when I get around to rebuilding it, so it's good to see the kit isn't THAT hard to assemble. Thanks for the writeup on getting it to work with the turbo!

CHIM Posted February 11, 2010 Author Share Posted February 11, 2010 nice! have you had a chance to drive it yet?? Yes, i did drive it, still a little boggy in the top end (still tuning) but it has a violent pull on the low end, we were in the process of working it out when the fuel pump quit. we'll get it:) Quote Link to comment Share on other sites More sharing options...
rxleone Posted February 11, 2010 Share Posted February 11, 2010 Wow dude that is amazing! Hope to see how she runs when she's all properly tuned etc... Congrats! Quote Link to comment Share on other sites More sharing options...
CHIM Posted February 11, 2010 Author Share Posted February 11, 2010 Wow dude that is amazing! Hope to see how she runs when she's all properly tuned etc... Congrats! runs very well accully:banana:, she's tuned in a running awsome! Megasquirt all the way!!! Quote Link to comment Share on other sites More sharing options...
idosubaru Posted February 11, 2010 Share Posted February 11, 2010 Nice write up, I've always wanted to do this just for kicks. Dont' have the time but should I ever this thread is a nice start. Thanks for sharing, good stuff. Do you have an approximate time for 1. Construction 2. Install 3. Tuning ? 4. Set up - sensors, etc? Quote Link to comment Share on other sites More sharing options...
CHIM Posted February 11, 2010 Author Share Posted February 11, 2010 Nice write up, I've always wanted to do this just for kicks. Dont' have the time but should I ever this thread is a nice start. Thanks for sharing, good stuff. Do you have an approximate time for 1. Construction 2. Install 3. Tuning ? 4. Set up - sensors, etc? assembling the MS-1 took about 2-2 1/2 hours, went pretty smooth Install i took my time on and took about 3 days in all for setup. Tuning is the time consuming one, never working with a Megasquirt i took alot of reading and hair pulling. Tuning is bar far the most complicated part. I do have a saved copy of the tuning map so anyone interested running a MS-1 on a EA-82 can hit me up, ide be more than happy to send it to you saving alot of time getting your car running. Tuning took me the better part of a week with ALOT of research. I'll go thrue the writeup later and include more details and part numbers for after market items used.

kingbobdole Posted February 12, 2010 Share Posted February 12, 2010 When we got Dorothy the 86 Turbo XT, she had MS 1 running on her high compression EA82T. Was very fun to play with for sure. I just sold it to my brother to put on a EJ25 SC project he has going. Quote Link to comment Share on other sites More sharing options...
eulogious Posted February 12, 2010 Share Posted February 12, 2010 So when are you going to get the LCDash? It looks sweet, and I am actually going to install one when I get do the MS to my MR2, but it would be great in a Subaru for sure! This is really good stuff!

eulogious Posted February 12, 2010 Share Posted February 12, 2010 Nice! So there is going to be more than one EJ22T RXs on the board now, in fact multiple ones, good stuff. That will be a fun project for sure, especially with the MS in it! Quote Link to comment Share on other sites More sharing options...

rxleone Posted February 12, 2010 Share Posted February 12, 2010 yup, that was my starting point for the fuel map. It seems awfully complicated to me, then again, I've never really worked on Fuel Injection. How did you learn all this? I have no idea what Dwell is or anything!

I have no idea what Dwell is or anything! lots and lots and lots and lots and lots.... of reading man. I now have a much better understanding of fuel injection after this project by far. Fun upgrade with lots of features over stock and truly a learning expirience. And yes, it was worth it. Quote Link to comment Share on other sites More sharing options...
CHIM Posted July 29, 2010 Author Share Posted July 29, 2010 Thought i should add as well, The MS-1 at minimum does not use all the pins on the DB37 conector. I choose to run wires for the currently unused pins anyway just in case we decided to have the MS-1 control somthing else later. Such as cooling fans or a turbo whastgate solenoid. Just a good idea to think about when your making your harness. Quote Link to comment Share on other sites More sharing options...
