I have same corvette with diff mods and never saw this one before.
For the map I ran calc airflow rate grams/s in data tab. In the column I ran rpm and in the row tab I ran ect
I get a scan log and paste it into B4307 and all of a sudden I have huge startup idle, idle hanging, cruise effect etc.
I can cut this table in half and all is well again. He is running a 90 mm tb and set B4349 to .0191.
I can get him a good tune like this but if the computer says desired air it wants and I cut it in half to make it work, would it be better to stick with the desired air it wants and readjust everything around it? I am just worried if I do it this way I will be chasing my tail for all the issues above. Easiest fix for me was to adjust B4307 till all those issues disappeared.
Anyone have an opinion on the procedure here? It seems I am coming up with the same end results... nice afr steady idle no cruise effect.
