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!

Sunday, I had some time to do some tuning. I was able to identify without a doubt that the "0" marking on the fan was indeed TDC. I even put a wooden stick down the #1 plug hole and rotated the engine to make sure piston was at its highest at that point.

Knowing this, I got the engine started, but could not get it to idle at 1000 RPM unless timing was set to +5 degrees as observed at the fan. It did idle nicely with this timing. With a bit of throttle input, the engine speed increased nicely to the maximun ignition advance set to 33 degrees, at which point I could see the 28 timing mark on the fan. I don't know how to explain this (IMG:style_emoticons/default/screwy.gif)

I am really starting to think, this cam was not the best choice for my engine (IMG:style_emoticons/default/sad.gif)
