Megasquirt Project, .....IT RUNS ! Options

[Michelj13]

Hi,

Although I have been a member for a while (since I purchased my 914), I have not posted much. I still love my 914 and it's is interesting how this car drives like an absolute go-cart.

Anyway, my engine is a carbed 2270 that I built up with the help of many including Jake, and I am now embarking on a Megasquirt project. As many know, megasquirt is relatively inexpensive for a programmable FI system. I find, however, that there is too much information out there that it is nothing short of confusing. I want to share my progress so that at the end of the day, some may learn and may become less intimidated. Hopefully I will be successful....we'll see.

I have so many questions that I will post, along with some things that I have already learned. ANY and ALL comments appreciated.

I made a youtube video of my progress up to date. Enjoy!

Well, I have been fighting a few issues before going on my first 5 mile drive. One of them, was a huge vacuum leak. I found a piece of wire lodged between the head and intake manifold. This caused the gasket to break and the result was a high pitched whistling sound when reving. I also added clamps to the boots connecting the intake runners to the plenum. I use a stetoscope to detect these leaks. I am also building a smoke machine to play with.

Now with a few less vacumm leaks I ran the car about 5 miles. The engine is surprising strong. Staying below 2500 Rpm, the engine pulls smoothly and nicely. When stopping, the engine almost dies, drops to 700 rpm and the climbs back up to 1000 before settling, so I need to work on the idle. I would love to see how folks are setting up their WUE etc.

After 2500 rpm, the there are a few hits as it climbs to 4000, but it kept pulling really hard to almost 5K. Wow, I can't wait to get this thing dialed in.

There is still so much to learn too. Wish I had gone to COP instead of CNP using ford coils and Type 4 ignition wires. The wires are not up to the task of shielding such a high voltage ( I have suffered at least 3 shocks (IMG:style_emoticons/default/w00t.gif) )
