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! http://www.youtube.com/watch?v=RoJfMZ9YgQc Michel (IMG:style_emoticons/default/smile.gif) |

I have a wideband O2 sensor from AEM. At idle, AFR is about 12.5, MAP is 85.
The timing can be adjusted with both trigger offset and advanced in TS ignition advance table. I have been around and around with these. It can get a little confusing especially looking through a mirror at fan markings. Bottom line is, at the fan, I need 5 degrees ATDC to achieve idle when looking at the fan markings. I know it does not make sense. I will be a few days before I can play some more. |
