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) |

As I have said in the past, I am slow but steady. Had a chance to install the new harnesses and both the "new" LS2 driver board and relay board (with tach adapter in place of one of the relays).
Once I got it hooked up, changed the oil and gas, filters etc. it started right up. Amazing!! I tuned it up a bit around the block several times and went to visit a friend - about 5 miles away. It runs great to about 3500rpm (with tons of torque, can even start in 2nd gear from stop, but then has a hard time reving past that point with low power. Lots of tuning to do yet. I was almost at friends house when the engine reved up and then RPM dropped to idle barely keeping engine running. I discovered that the MAP sensor tubing got chopped in fan as I did not secure it to anything. I fixed it temporarily with outer insulation of a coax cable and tape. I think it was still leaking but it got me home. So, total trip was 10 miles. Next phase of project is learning more about tuning, VE table, advance curves that work best, etc. Wish I knew someone in the area with a lot of Megasquirt experience. Here are a few photos of harness and relay and ignition boards Attached image(s)
