Assuming I have my fuel, load and idle all dialled in, how can I sort out my cold starts. Of course I have read the write up a number of times and know that I am going to need to see a richer mixture for a few minutes (to op temp) and even richer for the first few seconds.
Is it possible to sort this without a wideband? Do the narrowband HEGOs report enough to use the calculated FE% in TPRT while the are completely cold?

Re: Cold Start Enrichment
you simply give it more fuel and see if it likes it or not
