Busy time over the last few days. Now I can 'talk' to the ECU I needed some way to interpret the results. So I have built a program to do the analysis. Took her out 4 times today (beautiful weather, perfect for driving) to get some data points.
Here are some results (You can see the parameters I can analyse across the top of the screenshot).
First the temperatures in and around the car: Not bad
Now the ignition timing: Again looks good, switching from 5-25 deg advanced.
Finally the lambda (Oxygen) sensor voltage. This does not look so good
and seems to indicate it may not be working properly. More research
Worth pointing out I am temporarily running with both exhaust pipes
open. I will block one shut tomorrow and see if the data shows
Fascinating stuff. If anyone wants to try the software you can get it from http://www.rmrsoft.com/MEMS.zip
