Hi all,

I have pulled the drivetrain out in order to rebuild the transaxle. That job will be done this weekend! YAY! I am stoked! I will go from having 2nd,3rd and 5th gears (no reverse) to a newly built transaxle! I can't wait! (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif)

But that's not what I wanted to talk about. I had 40idf carbs installed on my 1.7 previously. This was a marginal set-up at best. I have now removed them and I am planning on installing FI. I will be going with the MS computer, mallory dist. and a 30kv coil along with stock T-body, injecters, plenum, and intake runners. If possible, I will use the stock D-Jet sensors as well.

I have a degree in electronics engineering, and have been working in the field for 10yrs now, so I know my way around a soldering iron. That being said, I plan to build the kit myself. I have read through several sites describing the theory behind the MS set-up and even found a site describing the installation on a sand rail. All of this info was very informative, and has given me the confidence to go ahead with the project asap.

Most of the info out there is pretty general when it comes to actual applications. I have yet to find a description of a T4/914 specific install. I know a few of you out there have already done this thing.

My question: Are there any T4/914 specific tips, tricks, methods and etc...that anyone could bestow upon my humbleness? I would be MOST appreciative!!!!

I had an 1.8 running the 1st version of MS a few years ago...I used the stock CHT and injectors (I used the L-jet resistor pack), GM air temp sensor and an aftermarket TPS....ran good once I finally put it on a dyno to tune it.

I used no O2 sensor

Last year I attepted to run the same MS on my 2.0, had nothing but problems, but I think they had all been owner induced (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)

Dave Hunt and another 914 owner here have put thousands of miles on their MS installed 914's...Dave took his install one step further and is running the ignition from the MS as well with the help of the ford edis system (crankfire)

Hopefully they'll chime in....Dave has some great info on his website detailing the install.

I have about 0 schooling in electronics and even I was somewhat successful in building one and getting it to work (IMG:http://www.914world.com/bbs2/html/emoticons/smash.gif) ....most errors with the MS are owner related (diodes installed backwards, not reading the MS build and install instructions.....)

I want to here this as well. I will be getting two megasquirt II units and am looking for the spark unit. Need the one for a V8 though. So everyone chime in.

There isn't really a dedicated "spark unit". The MS and MS II hardware is fairly generic, and what makes the difference is the software, which can be changed long after the unit is built. There are two major ways to have MS handle spark right now: MSnSpark, and MSnEDIS. The former uses a MSD or similar box to trigger spark from a distributor signal. You lock the distributor's advance mechanism and the advance curve is held in the MS software, programmable by the MS software using RPM and manifold pressure. This is easy to hook up, and you can use even a crappy 009 and still have a good advance curve. The latter uses Ford's EDIS system, which is distributorless, and uses a small box and a coil pack off several different early 90s Fords (Escorts are most popular). These parts can be had from junkyards pretty easily and cheaply. This also uses a crank-trigger wheel and sensor, which is something of a pain to fit on the Type IV. Dave Hunt has one on his new setup, and you can find photos of his setup by searching on this site. Perhaps this is the "spark unit" you mean?

For the MS or MS II should work on a V8 just fine, by just setting it to run on a V8. The EDIS spark setup from a Ford V8 can be used (different Ford box, marked EDIS8 instead of EDIS4 like the Escort box, and a different coil pack). Some have also run two EDIS4s in parallel on a V8. There's a writeup of these on the Megasquirt sites. Indeed, MS was originally developed on an SBC.

The most confusing part about MS right now is there are three hardware versions and three or four major software versions in development right now. Using the straight MS unit with the "extra" code is probably the easiest thing to do right now, as the "extra" code does fuel only, fuel and spark with a dizzy, or fuel and spark with EDIS. This is becoming the mainstream MS setup now, it appears. MS II is an add on to a regular MS, and will allow new development, but I don't believe the first cut will have many new features over the "old" MS. It will allow development to continue, and there will be some desirable new features added over the next couple of years. You should be able to get most engines running well with MS, so waiting for MS II isn't really necessary.

I've run MS for quite a while now and am working on EDIS ignition. Check out the link at under my signature. This all applies to fuel only.

Also check out sdsefi.com

It's not megasquirt but it has a ton of info that you might find helpful.

Cool! Thanks guys, this helps alot!

Dave: On your site, In the list of components, you wrote: "Modified Throttle Body reamed to 50 mm diameter". Is the reaming out to 50mm the only mod you did on the Throttle body?

Anyone else got some input? I figured there was more interest in this topic out there. Come on, the travel agent thread got like 5 times as many replies!

Wow! So when I finally get this thing back together, I will be one of only five people to MS a 914! Interesting...

I am currently attempting to attach a Mega Jolt Light Jr to my 2.7 /6. It is a stand alone DIS that uses the Ford EDIS system. Really easy to assemble and inexpensive.

Hello!!!!

I have had mine for over a year....my engine has been apart almost that long though.... (IMG:http://www.914world.com/bbs2/html/emoticons/dry.gif)

I set up the box on a bone stock motor, using only the injector outputs and tach signal. all relays were run through the ECU. no cold start, no warm up enrichment..

It ran good, easy set up, not perfect tune, but enough to drive it.

I then build my 2.7 motor with the twin weber throttle bodies...again, I was worried that my settings would be way off and I would not be able to fire it up...

again, no problem. This time, everything went through the MS relay box. I am now using warm up enrichment, but no cold start...I don't need it. Even though the temperature is now -3degrees, the motor will fire right up..

so I guess that what I am saying is that it is not hard to do...the hardest part is soldering the little buggers.

pic of my throttle bodies....

Those throttle bodies look nice! You are using injector outs, tach signal and WU enrichment only? Are you using a TPS?

I found this on evilbay, looks pretty neat. It's a little pricey tho...

http://cgi.ebay.com/ebaymotors/ws/eBayISAP...&category=42604

I am using the TPS.

Now I am using the CHT for warm up enrichment. I did not really need it though.

What ignition system are you using with the Megasquirt? If you remove the distributor, what are you putting in the hole?

I will be using a Mallory distributor. MS will just control the fuel injectors...

I too am interested in all info on this..
at the moment I have been waiting for a reason to start my project. I've only had the car for a year and it runs fine (carbs) So before I take it apart I'd feel a bit better if there was a group of people here with similar setups to share tips and code etc.
Speak up if your considering the same.. I was a professional mechanic for 7 years before getting into the computer field. I believe I am up to the task
I think I have a basically stock 2.0L

OK here is a pic of the stock FI stuff I will use. There will be a wide band O2 sensor installed later. (IMG:http://www.914world.com/bbs2/html/emoticons/mueba.gif)

no need for the MPS...sell it (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)

Where does that red tail light thingy go??

do I need one?
