Tried to search and read up as much as possible, but wanted to see if there was a definitive answer.
An accurate airflow measurement on this application isn't feasible. But, as I understand it, a COS will allow full use of the spark tables, (not just the first column, which the scan/tune trace showed it was locked into when I test fired the engine). Is this due to the COS performing a calculation to estimate air mass per cyl based on VE and RPM?

Most importantly, will the 01270001/2/3 COS allow me to properly control a 4l80e transmission with no MAF signal? I've read about disallowing certain DTC's to modify the trans pressures, but will the transmission still be calculating load correctly without airflow, as to shift as it was intended? Don't want to fry this guys trans :o

Thanks!
