So what's the best way to set the trim without a exhaust gas analyzer?
CO trim adds a fixed time to the real-time injection pulse-width. This is added across the entire RPM range. A CO trim of +1 adds 10 microseconds to the real-time pulse. A value of +10 adds 100 uS. Conversely, -10 will subtract 100 uS.
What Wayne said. If you do have an analyser, for the 8V, 5-7% CO, for any 2 valve head, 3-5% CO.
Why is the reading for the 8V double what it is for the 2V?
Wouldn't complete combustion cause the same readings in either engine?
And what about the 4V Daytona?
