Megasquirt XR4Ti **U/D w/ PICS and VIDEO** - PDenbigh - 10-22-2008
I just ordered Megasquirt II for the XR. In a perfect world, I'll test it out at the next NASA event @ Summit in early November. In a realistic world, I'll have it half installed, sorta working, and still test it out in early November :-).
Here's the build sheet so far:
Purchased Item Price
X MegaSquirt-II Engine Management System w/PCB3 - UnAssembled Kit $250.00
X MegaSquirt Stimulator v2.1 - UnAssembled Kit $48.00
X MegaSquirt Relay Board - UnAssembled Kit $65.00
X MegaSquirt-I or II Relay Cable $70.00
X MegaSquirt Wiring Bundle - 12' Long $40.00
X GM Closed Element CLT / IAT Sensor with Connector $15.00
X GM Open Element IAT Sensor with Connector $20.00
X MapDaddy 4 Bar MAP Sensor with Barometric Correction $60.00

X Megasquirt Decal $4.00
X Wideband O2 Sensor $80.00
Total Megasquirt $676.00

Right now, it's just fuel control. I'll be converting to a distributorless ignition system once I get this going.
I purchased everything from DIYAutoTune.com. I bought the "Stimulator" a while ago. I have had quite a bit of soldering experience but I was still really surprised at how easy it went together.
I'll update my progress here and on my website. I'm hoping there will be a lot of interest in this. I'm pretty excited regardless :-).
If anyone wants to help along the way let me know. If I actually find a way to have a scheduled work session I can let ya know.
Peter
*Edit* I took the plunge and went for all the distributorless ignition stuff. Might as well dive in the deep end and get it over with :-)

I always thought it'd be fun to do that with one of my 318s, if for no other reason than to do away with the crappy AFM, so I'll at least be interested in seeing your progress.... Good luck! I didn't realize how expensive the unassembled kit is though.
- Dave - 10-22-2008
I'm very interested since that is part of my long-term plan for the Z. Awesomeness!!
- ScottyB - 10-22-2008
i'll be checking in. i just flat out don't understand the nuances of tuning or much of the jargon and i want to learn.

Very cool Pete.
- JustinG - 10-26-2008
its really a great setup, i was running MSnS on the RS-T. I wish i could have found someone to tune it for me before she died. I was really interested in the potential of such a cheap EMS.
- PDenbigh - 10-28-2008
Parts are in!
Stimulator is assembled and Relay board is assembled. The actual "Megasquirt" board is getting there and I've confirmed communication with my laptop and uploaded the first round of software.
I've decided to just go all the way and do ignition using Ford EDIS. It's really not that much more work and I have to assemble things differently depending on which ignition system I'm using, so it was pointless to use the antiquated stock ignition when I'd just have to desolder and resolder when I upgraded to EDIS.
I think I'll have the assembly finished tomorrow. Next step will be installing in the XR.
Pictures to come!

The kit by itself, especially for a no or low boost application, isn't so bad. I added the relay board, a stimulator, premade harnesses to connect the two, etc, just because I've never done it and I wanted to eliminate as many variables as possible while still doing the soldering myself.
- PDenbigh - 11-01-2008
Everything is assembled and tested! It's so cool to have it sitting on our dining room table (in true MM fashion) blinking all sorts of LEDs that show injector banks, warm up enrichment, accel enrichment, etc.
I'm almost done with the fuel side of the new wiring harness. Tomorrow I'll start on the spark side, it's a little more involved because I have to use shielded wire in various places and there are more connections to make for the EDIS.
The EDIS parts won't arrive until later in the week unfortunately, so I'm just wiring to where I am going to place the parts so I can hopefully hook them in quickly upon arrival. In the mean time I can test sensors and read a lot on how this whole tuning thing works.
I'm really impressed with the system so far. Great directions and it's so much smaller and more simple than the 1985 version I'm replacing. Plus I'm going from my Mass Air (converted) setup to Speed Density, so that means two fewer connections to boot.
Will I make Summit? It's doubtful. Had the EDIS stuff been here already I would have better chances, but I don't even know when they are arriving (USPS FTL).

Damn, I wish I could be there to help.

Awesome Pete, let me know if you need any help, ive been playing around with tuning for a few years and tuned a few cars.
Ill be honest ive never tuned a car with megasquirt so ill be glad to read/follow along with your build.
- PDenbigh - 11-05-2008
Wow, what a project.
I've been working for about two weeks non-stop on this it seems. I just finished the last of the wiring though and the task list is starting to get pretty small!
The car will be ready to test (not start, test) this evening. I will start with seeing if the injectors work (MS has an injector test mode), then I'll see if I have spark, and I can test the base timing to see if I'm remotely close.
Then I have a bunch of reading to do before I actually try to start it.
Tomorrow is start day. I guess it's also the make-or-break day to determine if Summit is a reality.
Fingers crossed!
- Chris - 11-05-2008
best of luck! hopefully we get to see you and the car at summit.
- D_Eclipse9916 - 11-05-2008
Hey pete, when are you headed to summit and where are you staying? I was wondering if maybe I could catch a ride with someone?
- PDenbigh - 11-05-2008
We're heading up Friday evening, but we stay with Alison's Dad in Winchester. You're welcome to ride with us and I can drop you off wherever you're staying if you like!
- kcook - 11-05-2008
dj you better drive that thing to summit
- D_Eclipse9916 - 11-06-2008
Pete, thanks for the offer, I will actually be at the Winchester hotel of the sleep inn. So it should be right there. If its not an inconvenience to you all, im just not sure the car is ready.
Kyle I wish I could but I am taking all precautionary measures to make sure she is perfect before taking her on any more road trips.
- PDenbigh - 11-06-2008
PM me your cell phone number, mine's 540-421-0200, so we can coordinate this. I'm unsure of our departure time but I'm thinking sometime around 8-9pm on Friday.
No inconvenience at all man. Talk to you soon!
Peter

I'm giving up on Summit. Too many things to square away and I'm out of energy :-(.
On the bright side though, I think next season is going to rock!!

probably a good decision, but too bad you'll miss it. good luck finishing up the projects.
