Really cool work.

(IMG:style_emoticons/default/idea.gif) Now if you really want a STEALTH system, take the ECU and put it in a gutted D-jet ECU case, and put the MAP sensor inside a gutted MPS. (IMG:style_emoticons/default/biggrin.gif)


I like the suggestion. Any Chance ?

So will you be supplying the fuel map/program for it ? Or is it something the end user will have to fiddle with.

When are you taking orders (IMG:style_emoticons/default/biggrin.gif)

This setup will be expensive.

I think when everything is done, it'll be around $2000 for the bolt in setup.




So is this based on converting a D-Jet car to MicroSquirt or is this converting a carbed car to MicroSquirt?



Compared to going from carbs back to D-Jet (assuming you don't have any D-Jet parts already) what is going to cost more? D-Jet or MicroSquirt? I dunno for sure, but I'm thinking going from carbs to D-Jet would probably be in the $2k range.


anyway, this will be an interesting thread to watch.

DHunt did that. Said it was a royal PITA. This is stock enough for me. Not trying to win Parade Concours, just keep it looking more likely a 914 and less like a science experiment. (IMG:style_emoticons/default/cool.gif)

Costs would be about the same. If this becomes a kit, it will only need you to supply intake runners, plenum, throttle body, fuel pump, fuel regulator, fuel rails, stock cht sensor, and stock air temp sensor. I think that's it.

he wasted spark setups that you (TimT) are using, are they built into the systems?


Not so much that they are built into the system in that we configure the ECUs we use (Haltechs) for waste spark. It is all in the software configuration. We have been having a pretty good run lately installing about one per month E6X systems.

Dont want to hijack McMarks thread to much but here are some installs... We usually use Bosch 3 channel ignition modules..

3.7L Hi-output /6



coil board set up




Very nice!

Mark, If I were doing this install I might do something a bit different..

I'd mount the ECU inside the the car.. You can get a nice hefty rubber grommet to pass the harness throught the firewall Grommet. Then the ECU is bit out of the weather, and from what I see of the microsquirt harness, the serial connector for your laptop will be inside the car.

In the 911s we mount the ECU under the drivers seat usually, on a shock mounted aluminum platform... In a 914 you could easily mount the brain on the firewall behind either the driver or passengers seat.. and snake the serial connector under the carpet along the tunnel..

Sit in the drivers seat...laptop on passenger seat and tune away (IMG:style_emoticons/default/dry.gif)

Just a thought (IMG:style_emoticons/default/beer.gif)

If this were a traditional MS install I would definitely do that. But since the MicroSquirt has FAR SUPERIOR connectors which are all weather proof, I'm not a bit concerned about water. It's designed to be mounted on open frame motorcycles. Also, the serial cable unplugs once tuning is complete. This install doesn't need any additional holes cut in the body. I'll take a picture in a minute to illustrate the seals.

The microsquirt uses ampseal(?) connectors. We used to use the exact same ones @ GE in our motor drives that had to be able to survive FDA type washdown duty. They are VERY well sealed connectors.

Tim, I've got a twin plug 911 w/ a haltech E11. Im sending you an email.

Here's the picture of the AMPSEAL connector. You can see the red seal around the perimeter.

How did this thing turn out? Everything run alright? Where did you get the connectors from? I've got an ms3 board I'm going to put together at some point, but I'm going to stick with D jet until I feel a little more comfortable with it and have all of the parts put together to put it all together.

Before someone says not to change, I won't have a stock engine forever but I want to stick with FI.

This is a good thread. Certainly an update or maybe even a must do with some of the D-Jet parts NLA. Thanks for the write up.

Where does that connector go? is that the one that attaches to the MS?

I've been looking for a pair of connectors (male/female set) for quick disconnect between my engine harness and the body harness.
(Then again, I might just go with a handful of smaller connectors... hmm..)

Yes, that connector goes to the MS. AFAIK, ampseal connectors were difficult to get in small qty. That may have changed. Its not an issue w/ the MS since it comes w/ both halves (plus, Im sure they are ordering them in large qty.)

Hey Mark,

That is sweet! I saw a few earlier comments about a 6 cylinder. Have you given any consideration to doing a megasquirt or other system for the pmo throttle bodies?

Re MS and going distributorless, there is apparently some board in development that would let you fire up to 8 injectors and plugs on their own. In my mind this becomes a very efficient, very nifty coil on plug system. The injector thing is cool, but you're really only getting benefit at low RPM (primarily low temp, even) because your injectors are open longer than the valves at the top end.
Anywho, I would have linked the page but I couldn't find it. Does anybody know any more about this than I?

considering what you get and the current cost and quality issues of available induction systems, it's not that expensive

nice work

what about the naked wires on teh back of teh ECU plug?
