MegaSquirt

DJ19885.0 · 02-02-2010, 09:47 AM

I'm about to order a megasquirt 2 kit along with the eec-iv adapter board. I am so pumped to be able to do whatever the hell I feel like with the engine electronics. I will keep you guys updated on my progress. My friends have built one of these for a turbo van but have yet to get it to run yet, hopefully I can beat them to it! Any of you guys know of anyone running megasquirt? More info can be found at diyautotune.com if you were wondering.

I wonder where they came up with the name megasquirt lol. Never heard of it. What does it do? Does it replace your computer or just allow you to modify a few things?

More info can be found at diyautotune.com. It is an extremely versatile ecu that you build and program yourself and can be made to work with ANY engine. It can work in papallel with your stock computer or on its own. You are in control of every aspect of engine control via your laptop. It is extremely tedious to build and to program, but it should be a great learning experience for me, i'm excited.

Ok, well, I am currently at work but the tracking on my shipment says that it has been delivered! HELLZ YEA! I have already began the process of making a "relay cable" that goes between the megasquirt and the adapter box that will plug into my stock wiring harness. I have also started doing a lot of the reading and teaching myself how to use the tuning software and how to tune the computer. There is one heck of a lot to understand before you even want to think about cranking over your engine for the first time. I will begin the "how to" writeup as soon as I get home and can start taking pictures. SO PUMPED! I'll keep you guys updated!

Yea i was wondering on the name too lol. That seems tricky as hell. How much does that run you?

Awesome! Yea keep us updated. Seems pretty interesting. Id like to see how you set it up.

Well, I hate to say it, but I haven't got too much accomplished in the past couple of days and will be out of town this weekend, so not too much progress will be made until later sunday. Busy, busy, busy... But I will "update" the materials and cost:

For doing this to a mostly stock 5.0, this is what is reqired:

-Unassembeled Megasquirt 1 or 2 (2 allows for a wider variety of control, so I went with MS2) : $250
-EEC-IV adapter board (Not required but it makes using your stock wiring harness easy and clean. With this, you can just unplug the MS and plug your factory computer back in no prob): $67
-Relay cable to go between the MS and the adapter board : Free because I just happened to have wire and db-37 connectors from work =)
-DB-9 to USB adapter (Necessary if your laptop does not have a db9 port) : $20
-25 watt soldering iron (not too much hotter or you can damage components): $12
-Resin core solder: Free bacause I already own some
-Simulator board to test your megasquirt: $50 (I am borrowing one from a friend, so free again for me =) )
-Ford EEC-IV computer to harvest the connector and case from (the adapter board bolts right inside a stock Ford computer case) : $30

Total cost for me : $390 AFTER shipping.
You would need to either buy a relay cable for $70 or make one for about $20. You would also need the simulator, another $50.
That all totals to $510 if you decide to buy the relay cable and adapter board, and dont get anything for free lol.

This is getting me pretty interested. Does it come with instructions or is it just figure it out?

DJ19885.0 · 02-12-2010, 11:47 AM

There are several extensive manuals, writeups, forums, and how-to articles at the sites I mentioned above as well as at megamanual.com

Check it out, its very interesting!
