Hi,

Pscan unit arrived today and have done a quick live data scan. Been trying to turn data into line charts without success so figures only.

I was hoping it would be the upstream O2 sensor as that would be a quick fix but it seems not to be the case.

I started the feed with a cold start until temp guage was at normal - idle only.


Upstream sensor started at 0.63v and fluctuated between 0.2v and 0.75v straight away.

Downsteam sensor started at 0.47v and stayed at that for some time then started changing at 67c engine temp. Fluctuated between 0.11v to 0.9v.

Fuelling correction - not sure what this is, meant to use fuel trims but it started at 100% and moved from 85% to 110%.

Reported being in closed loop for entire test.

Any suggestions on what to test next? Engine coolant temp sensor seems ok, MAP sensor?

Iain.
