Some more small problems to struggle with that make that I still have no MoT. The small one was a loose bolt on the diff carrier (solved after a dive underneath the car), the complicated one was CO being too high and the labour intensive one was a cabling error to the headlights. I did a mess and mixed up ground with one of the headlight 12V+ wires. Silly me! Solved whilst resoldering, followed by adjustment.
The technical control mentioned a CO rate of around 8% which is far too high. During TechnoClassica in April I purchased a Gunson Gastester. Out it came to try adjustment on my own. Here is how I proceeded:
- run the car so it is hot (around 80° water T)
- connect the gastester and leave it for 8min
- calibrate the gastester to 2% and wait another 2min to let it stabilize
- put the probe into the exhaust and leave it there until you get a reading
- open the map in your ECU and go to the live adjustments (Emerald)
- tap 2 to decrease or 3 to increase fuel (injection trim)
Before you start, be sure to adjust iddle and check the TPS (throttle position sensor) setting.
I managed to set it to 1.6% which should be ok, than had a run and checked the value. It was slightly higher but still ok. I may repeat the adjustment just before I go to MoT next time.
Cheers.
