Trouble with setting Co - Cosworth
Evening all,
Took my Cossie for a pre MOT, most keen to see what the emissions are like!!

8% Co at idle!!
Didnt suprise me as the plugs have been black and the gaps were at 0.5mm - ive since set them to 0.65
So having read lots about Co's and fuel pressures, I went about dropping the Co down to a sensible rate. The setting screw by turning it anti clockwise dropped it down, but just to 3.5% - it would not drop any lower (ideally looking for 2.5%).
Its going to be setup next month, but I worried myself into thinking there maybe a problem with my ECU and I dont want to travel to a tuner only to find that out there and then!! Game over.
I did take the top off the ecu and checked/confirmed that the adjuster had contact with the gubbins inside.
Any ideas guys?? Chip is NMS for T34 and greys.
Huw
