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) |

WTF? Why do you have an rpm values that go from 700 to 1100 and back down to 400 and then jump to 2000 rpm?
No wonder the car does not idle. Your ECU is confused since you have two 700 rpm columns. This needs to be fixed now. Start about 100 rpm below your expected idle speed and then make smooth even steps all the way to redline. Tuning fuel for maximum vacuum at idle. This just means add or remove fuel (increase/decrease VE value) until your MAP value is at its lowest. On the cars I tune this usually means an AFR about 12.8 or so. Then you go back and change timing until the MAP value stablizes. Starting the car is a milestone for sure. Now you just need to start the tuning process. Think of it as changing carb jets with your fingertips. |
