now that good weather has arrived I have made some progress on this setup (that and the fact my stock ECU is giving me problems is speeding up this project)

So I purchased some things that are going to be helpful

one is a zeitronix wideband that will be installed into the car pretty soon I hope. This will be used for the MS. I am keeping the Narrowband in place for the stock computer right now. I am going to be running them parallel for a little bit. I am thinking I might even start the MS system just running fuel and the stock computer running spark for right now just to see how that works out.

The other toys that I have is the fuel injectors FIC 1150. Reason I started this whole project is because I needed more fuel

Here is something I built that I think is really helpful. I didn't want to hack into the stock wiring harness. When I went to U pull I found a 1.8 ECU that the stock clips can plug into. Also in the yard was a 90 laser and I hacked off the plugs off of the wiring harness. Put the two together and you have a wire harness extension!

I thought this would be really useful for tapping all of the lines you need and still not have to tap into the stock lines. In case this doesn't work I wanted to be able to plug into the original harness

Also what is helpful about this is that you are not in the car when splicing into the original harness. I don't have enough room in the car to splice and solder stuff. I can splice and solder connections in my own house before putting it in there. I love this thing!!!! plus now I can label what goes to where. I have tested this and it works. My stock ecu sits on the passenger floor board. Another thing is that if I even have to convert my car to 91 harness, flipping the two wires will be easy!
