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.

runs very well accully:banana:, she's tuned in a running awsome! Megasquirt all the way!!!

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:)

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!

To my understanding this board was here to give information and insight from people that have been there done that, Seems like the old friendly usmb is now a place to be critised for asking a question. sorry.

Oh no, im definatly not using the stock harness, made my own, just keep a few inches as pigtails. Im hoping to have her running tomarrow.

I havn't really started yet but i think i might, Im building my own harness from scratch so i should be able to give ya somthin.

Ok, so im getting close to finishing a megasquirt install on my nephews car, Anyone here using a megasquirt I that might have fuel maps for the EA-82 T's? Maybe know a good place look? I am fully prepared to build one from scratch but wouldn't mind taking the lazy way and usuing someone else's homwork as a starting point.

Top speed wasn't it's strong point, it was gettin there that proved to be the most fun. Thats just a huge tire bill. And it doubled as a flame thrower:Flame:

Love the comment "thats even with a blown head gasket":lol: I miss that car, sounds so smoooooth. IMO the best exhuast i have personally heard on a subie yet.

Mine is a 79 firebird tho, and it's going bye, giving up on the dream of what i wanted it to be.

Ok, so here's my RX, and yes it is really that streight, this is the side that has the only 2 body flaws, and im missing the wing

My lifted wagon has an allmost identical setup as crooner's minus the tip resonators, wich does make a much different sound. The tip resonators were added to keep the valume down . Here is both of my cars with custom exhuast that i did when i still worked at CmC (Exhuast shop). Ok crooner, your turn:).

Exactly!, there's tons of them here......driving around, they don't get crushed here, they get revived and driven. :-p The trick is finding a specific vehicle in the JY thats not stripped allready. LOTS of GL's and all the legacy's i find are automatic or missing the tranny.

The rat as it looks today.

I have been unable to find a legacy in the JY, i allready have the motor (tho i havn't seen it run so no idea what shape it's in) but it does have compression. I have been for a while now looking for a legacy 5 speed and unsuccessfull so far. I have the stock ECU and harness but i don't need it, im going to be usuing a Megasquirt system to control fuel and ignition. For ease and tunability. My biggest worry is that tranny, i have destroyed a few D/R 5 speeds in my EA81 turbo subie. I know that 2.2 trubo is gonna have alot more thump to it, was just hoping the RX tranny was better built. If the RX tranny is pretty much the same as the D/R im gonna have a problem.... I have come to the realization, "if it can be broke... Ill break it". Worse case, ill run the RX tranny till it breaks while still looking for an EJ 5-speed.

awsome!, that was my biggest worry. really don't wanna destroy it as there's not to many around, and i am un able to find a legacy trany for a reasonable deal. at this point it would be cheaper to buy a legacy than just the tranny. TY vagen.

I had junkie link it to me, i still can't find it for some reason... Anyway, i think i have all the info i need, i am still a little unclear on a few things but ill figure them out i guess.

If the high idle didn't start till you adjusted the cable you might have got it a little to tight, Also the linkage could be a little sticky from grease. I have an issue with my webber getting dirty and linkages getting a little sticky from time to time. I use a dry lithium greas as it doesn't attract dirt as much as a wet lubericant. Allso might need to use a different throtle return spring or adjust your current one. loosten your keeper nut on the cable and back it off slowly whith the car running and listen for an idle change.

I did find the writeup post from numbchux but the .pdf link isn't working, anyone have a newer link or a copy of the they could e-mail me?

OK, sonit's been a few years since i got my motorless RX and im gettin sick of seeing just sit in the driveway collecting dust. Being somewhat intimidated in cutting and wiring in the EJ ecu and harness i have decided to go with a complete megasquirt system. wassn't really looking forward to the task of wire diving, mostly the reason i havn't started this project sooner. i also like the idea of custom tuning my setup and possibly going to be going with an ECU managed boost control of the turbo. and not having to worry about fuel cuts. I can't seem to find this ever elusive EJ-EA swap writup, been a while since i have been on the usmb. A few questions... How well should i expect the RX tranny to hold up to the EJ-22 Turbo? What flywheel and cluth do i need for the swap? motor mount need to be modified? Can anyone link me the writeup? I will most likly be posting my progress as it happens, starting with the megasquirt assembly. I WANNA DRIVE MY RX!!!! Dayten.

depends on what the DC amperage of the switches is, not sure how much the wondow motors pull but i would say stay 15 amp or higher. the new switches will last years to come given there not super cheap. Runing relay's is alot more trouble than it's worth i would say, Worse case keep a few extra switches on hand in case one of the new one quit.

Yeh well mark is to blame, besides i blame stuff on him all the time, it's just easyer that way.

Awsome, finally got her wuped!, rite on man. First time on in over a year, great now im gonna get addicted to the usmb all over again:banana:

Ok, found them, im used to them being under the dash, the diognostic plug (Green One) was plugged in, i am changing the throttle body now, hoping that does it. Im sure there is still another problem, like a stuck injector......... When i say it was flooding itself that was an understatement, it's drowning itself. I'll see what happens, i might be back on here asking more dumb questions, Thank you guys alot, your savin my rump roast! ~CHIM~
